I took my 69 down to the Speed Merchant in San Jose to run it on their chassis dyno yesterday. They use a Dynapak dyno which bolts to the rear axles after removing the tires/wheels. This allows no wheel slippage on the rollers. I had run the car a couple of weeks ago on a Dynojet dyno but we couldn't get a torque reading as it spun the tires on the rollers. Ended up with 482 hp and 567 ft lbs at the rear wheels. I was disappointed on the hp as it should make over 500 to the ground. But the torque was actually over 600 below 3000 but this was the lowest rpm we could start the run at without the 2004R downshifting to second gear. We also locked up the converter before the pulls so you don't get a high flash reading from the converter stall.

So it's probably pushing 700 ft lbs of torque at the crank and 600-650 hp. The EFI makes it very driveable and I've gotten 13-15 mpg around town (no freeway mpg yet) without even leaning out the cruise yet.

The one thing they said is that they feel there may be 80 hp (crankshaft) or so loss in my exhaust system. I have 2" super-comps and a 3" "X" crossover/Torque Tech mandrel bent exhaust with 3" Dynomax ultra-flo's. Pipes go to the rear of the car. Anyone have any back-to-back engine to chassis dyno numbers?

Jody

Pics of the car are at http://albums.photopoint.com/j/AlbumList?u=1535951

that is monsterous! What is the build on the engine again?

It's an aluminum Yenko block with .060 over LS-7 internals. I've got a Comp solid-roller; .650 lift and 264@.050 with a 110 l.s. It has ported Canfield heads, Victor Jr., and a 1000 cfm throttle body. I use a Speed Pro computer. 2" Hooker Super Comps, and 3" X-pipe exhaust. I'm also running one of Bruce's (WE4) 2004R's.

The car is a lot of fun to drive and makes torque for days. I'm getting about 14 mpg average around town. I still haven't checked the freeway mileage yet but will soon.

The next step will be a bigger throttle body and some 2 1/8" headers. Then I'll just drive the heck out of it!

I seriously doubt your exhaust is holding back that much power, if any at all. 3" exhuast pipes should easily support 650 HP if you have an efficient muffler. I myself run a 580-600 HP 414 ci bbc that runs 10.92 @ 122 mph (3550 lbs race weight) with 2" primary x 3 1/2" collector Hooker Super Comps and 3" pipes with 3" straightline Performance mufflers. I did some testing and found that the mufflers on or off made no difference in the performance at all. The 60's, 330's, 660's, 1320's and mph were all the same with and without mufflers...all tested on the same day. If anything, I feel 2" pipes are a bit large on my engines HP numbers, but that is all that is available for my application. If anything on your car, remove the tail pipes and install turn downs as they are the biggest restriction you have right now. I seriously doubt 2 1/8" headers will provide you any ET on your time slip. Your simply gonna move the power band up the curve a bit and sacrafice much needed torque to get your car moving from a dead stop.

BTW, now that you have the bench racing numbers, what does the thing turn in the 1/4 mile?

The reason I'm swapping headers is because the Hooker's don't fit worth a darn with the Canfield heads and their raised exhaust ports. I found a guy who builds headers specifically for the 69's with Canfield heads but the smallest he builds is 2 1/8". As far as torque, to lose a little would probably be a benefit. I am planning to run the car at the track but I've got to install a driveshaft loop, longer wheel studs (just in case), and I'll need some slicks. I'll post the numbers after I run it. I'm not going to run a cage or try to be NHRA legal so I'll probably only get one try at it anyway.

Jody

Here is what Hooker and Dynamax use as far as HP and exhaust sizes:
HP-------single--duals
200-300----3"----2.25"
300-400---3.5"---2.5"
375-450----4"-----3"
450-550---4.5"---3.5"
550-650----5"----3.5"
650-800-----------4"
800-1000---------4.5"
1000+-------------5"

My car has 2" hooker header to dual 4" exhaust with an H-pipe. Now I'm making some 3.5" tailpipes for it. Later I will be going to some 2 1/8" headers!
I do think that the exhaust may be hurting you some, you should go dual 3.5"!
Do you have the suspension setup on the car?
Atleast some traction bars?
When you run your car at the track make some 1/8 mile passes first, dial the car in, then when you think its running good make a full pass. Thats what I do, I dont have a cage either - yet! I'm interasted in seeing what your car runs, some 10s I hope http://www.camaros.net/forum/smile.gif

67RS502,

My car isn't set-up for drag racing. It's more the pro-touring route with 17" wheels and Baer brakes, Koni's, etc. So that will obviously affect the launch.

I'll run it the same way I ran my Cobra replica. I was limited to no quicker than 13.0 by the son of the track owner due to no cage, convertible, etc. It has an EFI 406 with a Tremec TKO and is not set up for drag racing either. I figured I'd work on the launch and then lift at half track. IF I got what felt like a good leave I'd go ahead and run it through. With the drag radials it wouldn't hook better than a 1.90 60' and ended up with an 11.11 at 128. I later returned with some Hoosier slicks I borrowed and ran a 10.68 at 134.

I figure with the 69 I'll do the same thing except I won't even attempt it without slicks. I'll report e.t's when I'm done. And yes, I'm guessing 10's.

Jody

67rs502,

I assume the world of "bigger is better" is still alive and well in your part of town??? Those figures are out of line IMO, unless their mufflers are restictive which I would assume and bet they are. Going too large on exhaust pipe size will slow exhaust velocity which will also hurt scavenging and torque production. Your best bet is to get some flow numbers for the mufflers you run and compare them to a GOOD muffler like the Straightline Performance mufflers that I run. I know of quite a few examples of racers running 600+ HP engine combinations using 3" exhaust with no loss of performance.

Just remember that Chuck Samuels of Fastimes Motorworks used simple 3" Dynomax turbo mufflers on his El Camino back when it was running low 9's on 9" slicks in the early 90's. We need to start questioning the current trains of thought and get away from this bigger is better attitude...otherwise people like Jody might spend hundreds of dollars replacing parts for bigger stuff and actually slowing down in the process.

To be honest, that pipe sizing chart looks like what Flowmaster uses. They are one of the worst mufflers made IMO...their tech people make excuses and change their recomendations when your car slows down with their mufflers. Due to the baffle design, their is built in restriction which is why you have to run a larger pipe with flowmasters to overcome that inherant restriction due to the baffles. Flowmaster is and always has been about marketing and hype.

Jody,
Looking at your pics of your Camaro and Cobra I just had to change my shirt because of all the drool. You have some nice rides. May I suggest on your 69 Camaro that you tie the frame together. That modification is fairly easy and sorta hidden. MY flex flyer 69 was ripping the drivers side rear 1/4 apart from the torque of the engine and when I installed my 4 point cage and frame connectors I felt I was driving a different car. It made a huge difference. Boy oh boy just when you thought you had a fast and cool Camaro...somebody else comes along... http://www.camaros.net/forum/smile.gif
I wonder if I could stuff one of those blown alky motors under the hood. (kidding)


[This message has been edited by Toby T. (edited 08-15-2001).]

I see you got it running. With power like that it should be fun. I have a guestion I see you have a 67 Nova does it have a 200 4R in it? I am looking to put one in my Nova but I am worried about the physical size a 350 turbo barely fits. I know that it is the same length etc. But a 400 will not go in a Nova without floor mods. and I really don't want to do that.

Slowazzbu
That chart is not for muffler, its for the actaul pipe size you're to run for the HP you're making - Straight from the people that know best.

The perfect exhaust would be the right size headers and some 18"+/- long header extensions. Since streetcars need an exhaust system its OK to run a step bigger pipe after the headers since the you've got the extra length of a full exhaust.

You menstioned Chuck Samuels car, well that was the early 90s, exhaust technology has gone a long was since then. If you look under Chucks car now, or any other "fastest streetcar shoot out" guys car you will see dual 4", 5" and even 6" http://www.camaros.net/forum/eek.gif systems.
The Header size is whats important, because after the 18" of pipe it should be an open exhaust anyway!
There are a few things to stay comservitive on, like heads, stall, and gears but...
Bigger is better - engines, cams and my favorite EXHAUST!

The main reason the manufacturersrecommend larger exhaust pipes is due to marketing...they know people like yourself wanna hear bigger is better, so they naturally will tell you what you want to hear. The same holds true with cams...most of the major cam companies also know what you want to hear and will tell you exactly that even if it compromises performance.

Tell me how bigger is better given this example...my own.

414 bbc (destroked 427, 4.280 bore, 3.600" stroke), 6.500" long aluminum rods, 10.5:1 compression, custom Venolia pistons. Old indiction was a Crane solid roller with .712" lift I&E, 272/278 @ .050, 312/316 gross, 110 lsa, GM 990 rect port open chamber heads fully ported, flowed 325I/250E with 2.25/1.90 valves, Edelbrock Victor 454R intake, Pro Systems 8896 1100 cfm Dominator.

This configuration in my 3550 lb Malibu would only run 11.40's at 125 mph, and only 60' in the mid 1.70's, shifting at a rather high 7800 rpm.

I then sold the entire induction and went with a much smaller Comp Cam with .653/.660" lift, 248/254 @ .050, 286/292 gross, 110 lsa solid roller, GM 781 oval port heads that "only" flow 265/200 cfm with 2.19/1.88 valves, smaller Victor Jr. intake, and a 850 Holley. The shortblock remained untouched.

This configuration now runs 10.92 @ 122 mph with a 1.55 60', now shifting at 6900 rpm. The headers and exhaust remained the same 2" primary, 3 1/2" collector, and 3" pipes with 3" Straightline Performance mufflers.

Now tell me that your "bigger is better" mentality works! That line of thinking is perpetuated by the manufacturers and people like yourself who want to hear that, when in reality many times smaller will run faster, quicker, be more reliable, less maintence, and last longer.

I agree larger cubes are better up to the point of where traction becomes inconsistent, but cams & exhaust have to be kept conservative to maintain torque...HP don't mean squat as torque is what moves vehicles from a dead stop.

Sure 4 & 5" exhaust are used, but now were talking about 1500-2000 HP Pro & outlaw street cars, not 600 HP street/strip cars.

Please tell me how a lil 414 bbc with 10.5:1 compression & tiny 3" pipes & muffs can run the same ET's as a whopping 502 ci bbc with 4" exhaust???

First, I want to say I didnt mean to tick you off, and dont take me so seriously------&gt;
I dont have the "bigger is better" mentality when it comes to everything! Otherwise I'd have a 2 1350 dominators on top of a sheetmetal tunnelram, a huge solid roller, 14 to 1 compression, 5500 stall with a T-brake, and 488 gears!
I have to diagree on the pipe size, I think thats the correct info, I talked to both manufacturers + I've read alot on the subject, where an engine will pickup big number by going to a big exhaust. Hey whatever smokes your tires http://www.camaros.net/forum/smile.gif

Second, I told you I dont believe in huge heads, and that is most of the reason you car combo wasnt working. Yea the cam was way too big too - by my standards.

Third, here is what I've got a small hydrolic roller - 252/263 611/612 and 049 oval port heads with 219/188 valves. I think your idea of a big cam (race) is different from mine (street)

The difference is my car is a street car yours is a race car. I just jump in mine and drive it 100 miles in one day - no valve adjustment, or buying new springs once a year.

And not to offend you or anything but how will your 414 run with my 502 streetcar http://www.camaros.net/forum/wink.gif

Enough, I got off of the Chevelle site because of things like this. I don't care if your 3/4 ton truck ran 9.00 with a small block this is supposed to be an information site not a mine is bigger than yours site. A life long friend just went 5.39 262Mph in his Federal Mogul car. He has no sponsers and works out of a garage. If anyone had the right to brag he does. But not a word he talks about his blown hemi 32 Ford street car.

Not sure I get your point on the race vs street cam...mine is a Comp Cams Xtreme Energy STREET roller grind. Valve springs only have 170 lbs seat pressure and a little over 450-475 lbs open @ 1.25". This is by no means a radical cam, or high valve spring pressures. These springs will easily last several seasons for me. BTW, I haven't needed to touch the valve lash since March.

Yes, at the present time my car is stuck racing only, but that is due to Maryland's strict emissions laws which are keeping me from getting tags at this time. Believe me, I've wanted to drive this thing on the street for years now...guess I just gotta wait for the car to turn 25 (3 or 4 years off) and hope I can get classis tags with no inspection...we'll see on that.

Oh, and I see you pulled the old "bait and switch" with your ET's in your sig... That's OK...I've not got anything to prove to anyone about my cars performance http://www.camaros.net/forum/wink.gif

Talking with manufacturers is one thing, but going out an testing is another. Have you taken your exhaust off and seen what it's done open heads, and maybe even smaller pipes??? You might be surprised to go faster with smaller pipes, but then again, maybe you should get anymore torque, cause your not hooking as it is considering your weak 60's for a 10.40 pass...but then again, yours is a street car, and doesn't work like a drag car.

We aren't comparing apples-to-apples, so this conversation isn't going anywhere...but I still stand by the fact that 3" exhaust will go no slower than 3 1/2" or 4" on a 600HP bbc.

I will compliment you on your rides performance and that you were quite smart in choosing GM iron oval ports and not running the high performance shiney aluminum rectangular port heads everyone seems to think they need.

On second thought...I retract every thing I said above. It bugs me to death to see misinformation beign given about certain subjects, but it looks like you guys have your own group of "experts", so I will leave this stuff to them. My experience is race related, not street stuff, so Jody is better off listening to your advise as he already said his is a street car and not a race car. You can get buy with mismatched parts on the street, but not on the track.

Wait a second I said I didnt want to offend you, you had some good advice. The head/cam swap that picked up your car are good. And not all engines respond to the same things! Some 502s I've seen pick up with huge headers, like 2 1/4" and 4 1/2" collector http://www.camaros.net/forum/eek.gif, that doesnt mean that all of them will. And if your car didnt slow down with the 3" exhaust , thats usefull info too, thats how we all learn!
Didnt mean to get on your bad side.
Its all about making a good combination.
We study the stuff and make an educated guess. It took me a while to get a 600hp streetable 502.

Wow!!!!!!!! Leave for a few hours and.......... I appreciate the info one and all. The reason I went with aluminum heads is because of the aluminum block. And I KNOW good oval port heads would have made even MORE torque than the Canfields I have on there, but again, they were a very good deal and I already had the rectangular EFI manifold from the ZL-1 heads.

Toby,

I have installed frame connectors but can't get myself to put a rollbar or cage in the car....yet anyway. I know you're right about stiffening it up though. Thanks for the compliment!!!!

Oger,

I don't have the Nova anymore. It came with a TH350 and I swapped in an M21. The 2004R SHOULD fit as body-wise it's very close to the TH350. But those Nova's have VERY narrow tunnels. You might call Bruce at Performance Trans and see if knows of any areas the 2004R is larger.

I'm actually (probably) going to build a 2 1/2" "X" system identical to mine just to see how much quieter it is. The tone of the 3" with the Dynomax welded Pro Flo's is nice but there's more resonance inside the car than I like. If it kills the power I will put the 3" back on. Thanks again for the info.

Jody

I do not mean to over simplify engines because people really enjoy working on them but I like the idea of buying a nice 500+ hp big block crate engine, putting a nice under the hood super charger with moderate boost and crank out 650 to 700 HP and drive it all day long with no problems. All this talk of engine combo's makes my head spin. I feel unless I am actually racing a car and trying to get every tenth of a second I can, I just don’t worry about it. Life is too busy. I do like to play with carbs though and try to tweak then a bit. Just my 2 cents. I do try to think through combinations but do not experiment too much. By the way I use a set of 3-inch exhaust with an X crossover from Mr. gas and pipes out the side under the door. I also use a set of stainless Edelbrock straight through design turbo style muffs. It works for me very well with my small block.

As far as tweaking/tuning every last tenth out of a combo - Thats my favorite thing about HotRodding! I love having a car combo that runs good for what its, wether its a stock 305 or a street/strip 502, I just like cars that run good http://www.camaros.net/forum/biggrin.gif My buddy has a 454, 70 chavelle that runs 11.50s and another friend has a 302 mustang that runs low 12s, both are streetcars and are budget motors, I think thats cool. Other people like show cars, and others restorations. There are alot of different thing to like about HotRodding, I just like a tweaked good running car - its a never ending thing http://www.camaros.net/forum/wink.gif

since you know all thats been done to your engine,i would like you to download Dragstrip Plus (demo) from www.martelbros.com (http://www.martelbros.com) . I know the gross HP is a little high,but the 1/4 times are only .2 slow. I did a "quick compute" on your car giving it a 3200 lb. weight with driver,4.11's,and a 4500 stall. Its saying low to mid 10's. Hope its true http://www.camaros.net/forum/biggrin.gif. And could I have some more info on this 200r4 please ?

Those four and five inch systems are fine for juiced/blown 1400hp street cars but a 600hp NA cruiser/bruiser can benefit from a high flowing three inch system. Length, Volume and Flow must be balanced for the motor's purpose and combination. Most folks go big early and wonder why it didn't work. Right Todd? BTW my 427 runs 6.97 @ 98.48mph with 1.55 60'1969 SS @ 3200# (do the math, that's 10.90 in the 1/4)and I probably have less $$$in the whole car than you have in your motor.

My10secss,

Who are you talking to? If it's me, I wouldn't doubt that you have less money in your whole car than what my engine costs.

Jody

He, He!! Question, How far is my Dyno2000 and Drag off on my 496 I put together on the cheap?

I've posted the combo many times but would really like to hear from somebody that has ran one. PLEASE!! pdq67

496, Merlin ovals, 9.8 CR, 750cfm 3310-2 Holley and Strip Dominator, CC's 282S solid cam 282/236 type and finally 1.75 headman headers. All going through my M-20, 3.31's and say a 26.5" tire.

My point exactly!! If I listened to every speed shop "pro", magazine guru, or website wizard, I would need lottery winnings to build a car. If you are ever in the Carolina's with your "classic" come get you some at one of our quaint local racing establishments. BTW we don't take American Express, just cash. Bring lots, you'll need it.

For all you guys that love 1.75 tube headers on you BBs check and see how much of the header tube overhangs the exhaust port.

My10secss,

What's with the attitude? I never said my car was better than yours, faster than yours, etc. I just posted some dyno results, that's it. This car is a driver, in my opinion, with 4wdb, 17" wheels, overdrive trans, A/C, PS, etc. It's not a race car. And I didn't build it to see how far I could stretch a buck......so what.

By the way, 10.90's ain't gonna cover this car.

To each his own. No use getting an attitude. If someone decides they want to spend a LOT of money building their car, it's their perogative, much like it is your's to be thrifty. I've probably got as much money in my engine as Jody does. My engine alone cost $18,000. I'm not asking for your approval. It's what I enjoy, and it was worth every last penny. I think Jody's car looks awesome. I'm glad there are some people out there that have the money to make a car look that sweet. Gives me something to shoot for. I also like to see a low-budget car run 10's. IMO, that's an accomplishment. Noone is bagging your stuff, so have the decency to do the same. Just my 2 cents.

If you're talking about my set-up your wrong.
I think I probably have the cheapest 502 in tha world. I got the block for $ 800, and used stock cast crank and rods. The Whole engine cost me $4500, I think that pretty cheap for a big block.
And as far as th exhaust I was just posting the size chart of Dynomax and Hooker, thats what they told me they use, and I thought it would be good info for everyone, since there is alot of big horsepower engines here http://www.camaros.net/forum/biggrin.gif
I think the big freeflowing exhaust is one of the reasons why my car runs well, just my opinion. http://www.camaros.net/forum/wink.gif

I think this post got kinda crazy. Jody, that is a sweeeeeeet ride. Pushin those kinda numbers, and probably 18-19 mpg on the highway. I love it man.

Thanks for the comments guys! This thread is taking on a life of it's own! LOL!!!!!!!!!!

Personally, I like low-dollar and high-dollar cars. This particular one just seems to break the budget, so to speak.

If you're talking about my angine costing more the your car you're wrong. My 502 is probably the cheapest one on the planet http://www.camaros.net/forum/biggrin.gif, I have around $4500-5000 in the engine from intake to pan. I got the block for $800, had some stock cast rods and crank, some stock 049 oval port heads, a hydraulic roller cam and Team-G intake. I think thats cheap for a big block. And as far as the exhaust size chart, I was just giving that info out because there are alot of big, high horsepower motor here. I was just posting what Dynomax and Hooker uses, I think its useful info http://www.camaros.net/forum/smile.gif And I think the big freeflowing exhaust is one of the reasons why my car runs well http://www.camaros.net/forum/smile.gif

Hey Camcojb,
I saw your car on a trailer going down to Speed Merchant. You were going south on 680 when I passed your truck. I was very impressed with the car. Unfortunatly, I was distracted by my mission to get to GM Sport Salavge to talk T-56's with the guy for my 68.
Very nice
Rick

Rick,

Yep that would've been me. Thanks for the comments.
