Just got a g tech for christmas, my 454 isn't running yet so i took my 71 firebird out down to a long street, I was throughly dissapointed when the lowest numbers i could get were a 14.07 at 107 mph, with a 5.6 0-60mph. I was expecting low 13's. I couldn't really get much traction in first gear, but it wasn't too bad, the tires were spinning but the car still launched, it didn't just sit on it. im wondering if the high numbers are do to traction? the mph seemed a little high for the et time? im running a pontiac 400,comp cam,big valve heads, dp holley, rpm intake, headers, msd,
richmond 5speed, 3.27 first gear, 3.08 rearend, dualfriction clutch, 275,40,17 in the back, with subframe connectors, traction bars, and stiff multileaf springs, I have beat stock LS1's before and those run 13's! Does anybody think mid 13's are possible with some traction? whats a good way to launch with street tires and a stick? Of course its probably just because its a pontiac, can't wait to finish this nova 454!

I was disapointed when I did mine too. Mine said 13.0 at 118mph. I can't get any traction in first, so I have to pussy foot it then nail it in second and hope it hooks. I've heard g-tech will show a few mph more then the strip. I know my mph is high too, 118 is what most high 11 second cars run.

How does the g-tech work anyway. I've been thinking of getting one. Sounds like you guys aren't too impressed with the accuracy.

Yeah, thanks for the reasuurance, i am wondering about my mph compared to my et? If your 454 is only pushing 13 with no traction that makes me feel better! The next step for this car is trying to make it hook better, the g tech is worth the money and for the most part is accurate, i am happy i have one.

Cody,
The truth hurts....most people do not really realize how fast a low 13 second run is. A 14.07 in street trim is not all that bad. If the tires spin more than one or two revolutions, you have probably lost at least a second. Keep working at the launch procedure, or get a set of slicks.
Hope this helps,

I went back and tried again today, this time i got my launches pretty good, i rode the clutch and then punched it, got a little wheelspin but definetly a lot better, now my times are 13.98, @106.8, and 0-60 5.66. These are all better times but i am still dissapointed, I thought i could keep up with a stock camaro. stupid pontiac 400 is all torque no hp. I debating whether i put this 468 in a 68 camaro or replace stupid pontiac engine, hmmm, think i will go with chevy car. anyway at least i got into the 13's but what really suprises me is how i have beat many cars that should be faster than a high 13. Well thats what i get for driving a pontiac.

I was dissapointed as well with the results of my G-Tech, but only cause of my poor traction. (wasn't the Camaro). Appart from that the results were vey close one from another so it wasn't the meter. I think the problem is that those things start counting inmidiately your car feels the slightest contact in the clutch, and those miliseconds count. By the way I'm not using mine anymore...

Actually I can start rolling and mine won't start until I actually jerk the car. If i wanted to I could cheat and roll out first and then nail it, but what would be the point of that! Anyway, i think it is a good tuning tool. If it isn't raining this week i decided that i am going to swap on a 850 holley from my 454 for the 650 on it right now, I know that is a humongous carb for this engine but just going to see what happens, also i am going to take my woofers and box out of the trunk to try to lose some weight, see what the results are. I am convinced that high thirteens suck!

BillK hit it right on the head...most people really have no idea what a 13 second run feels like. 13's is pretty darn quick on street tires. A lot of the so called 13 second late model camaros, mustangs, vettes, etc only run those times with a decent driver behind the wheel. Not every yahoo with a confused look on his face can pull 13's out of a LS-1.
As far as accuracy is concerned, they arent too bad...certainly better than a computer program. The mph will always read higher than the strip because the g-tech reads instant mph at the end of the 1/4 mile instead of average speed over the 66 foot traps at a strip. The g-tech wont replace a real drag strip, but it is a great tuning tool...and its great to embarrass your buddies who wont go to the strip with their "bada$$" car

Welcome to the world of torque, Cody. It's torque that accelerates your car, and the ability of your chassis to use that torque will produce a lower e.t. If you look up your speed in the NHRA stock records, you're looking at mid-12 second e.t.'s for your car. If you're interested in a real torquey Pontiac engine, look no farther than Jim Hand's 11-second wagon pictured here. http://www.boyleworks.com/ta400/psp/rebuild455jh00.html

Thats a big car! I am not trying to bash pontiacs I have invested a lot of time in this car, and have done a lot of investigation and research. This engine has always had a lot of torque and it has always ran out of breath before 5 grand, we will see what the bigger carb does. I have realized that the mph is high for the et, i am going to try to dwindle my time away. What everyone is saying all makes sense. but i still want low 13's. But in defense of chevys, I believe they make more power and torque, especially big blocks, both of best worlds, yeah torque gets you going but you need horsepower to keep you going. My suspension is fairly tight and stiff, which probably isn't good for qt mile. How can i tune it?subframe connectors, dearched high rate multileaf springs, rear swaybar, all polyurethane, lakewood "cheap traction bars" should i bring the snubber on traction bar close to the leaf spring, there is about and inch space right now. the front is real loose stock mushy springs and kyb's, the front sits a little higher than the back. My launch isn't too bad, ride the clutch some then punch it, only get some wheel spin. How much better can it get and will it really affect my et by that much?

[jshelzz]

sorry to say cody, but your all tow and no go! you'll never beat an LS1 or Mr.cameleon lehmer with that E.T. I suggest you just focus on your 454 from here on out.

[onovakind67]

Cody,
If you want to tune your car, Sacramento is open on Saturdays for test-n-tune. Let me know if you want to go and I'll give you a hand.

It is hard to substitute the real thing. I don't have any experience with the G-tech, but I wouldn't get down on myself (or my car) over what the G-tech told you. Go to the track (I would take onovakind up on his offer), with youe mph you could very easily be in the 12's. It will take good traction and a properly setup chassis. I think 12's are well within your reach. Most people have never even felt a 14 second pass let alone 13's (keep your head up).
Jshelzz, I take it you know Cody personally? The people here don't take kindly to ignorance or negative comments. Just thought I would warn you. If you don't have good info to offer you are better off keeping it to yourself.

Yeah i know that fool jshellz, he doesn't even have a camaro, he has a ford maverick with a 289 2 barrel and stock hubcaps that runs seventeens ! onovakind, maybe i will take you up on that offer, sac is kinda far, but not that much farther than sears point, maybe next weekend if it isn't raining, I wasn't sure if tracks were still open during the winter, that is pretty nice of you to suggest, thanks for all the positive responses.
