I was wondering what info is needed for someone to run my combo thru Drag Stip Dyno?


Thanks

For Desk Top Dyno:
Engine cubic inches (Bore & Stroke, number of cylinders)
Cylinder Heads type (stock or performance, valve size, full or pocket ported)
Compression Ratio
Induction (carb size, manifold type, Injection type or Blower type)
Exhaust system (stock manifold, Large or small header, with or without mufflers)
Camshaft (lifter type, lift and duration From seat or 0.050)

Sorry, I didn't know which you were looking for.
Desk Top Drag:
Vehicle type (weight, wheel base, drive wheel weight% (69 camaro is 44.0%) and frontal area (69 camaro is 22 sq. feet))
Engine (HP)
Drive train (Transmission type and tranny gear ratios, convertor and stall speed)
Rear drive gear ratio
Tire static diameter, width and type (street, hi-po street mild race or race)
Driving style (Launch rpm, shift rpms and engine redline)
Weather conditions (typical is 60% humidity, 75.0 f, 0 wind speed, 800 ft. elevation and 29.05 humidity

Ok gotcha!

Wow, there is some info that I don't know off hand hmmm......

Ok I'll give the info that I can answer maybe someone can plug it in for me! :D

86z28

3450 w/me

DD2000 came up with 504 hp and 483 tq I believe I'll check it though

th350 stock gear ratio

3800 stall

4.30 rear

28x11.5 et streets

as for launch rpm and shift points I will not know as I am installing a different cam Crane solid Power Max 114681 F-280

If any one could run that and tweak it a bit I would appreciate..Thanks

11.51 @ 117 mph with a 1.61 sec 60' time.

That's way ball park because you never even told us what kind of engine this was or what RPM the peak HP was at. I just used the power curve from my 383 which is also right at 500 HP according to DD2k. I put in a "reality adjustment" before I put it into Dragstrip Plus (based on the correction between what power DD2k says my engine makes and what the Dyno and ET's say it is)

Sorry about that! It is a 331 and the cam is rated from 3000 to 6800.......But I'm sure in the 327 it will wind up pretty high......I like your guesstimate lol cause I was being more cautious in thinking maybe 11.9!! But I hope I'm wrong lol.......thanks

I got close to those # also.
11.63 at 120.1 with a 1.98 60'

If its a 331 then the TQ will be quite a bit lower than the 383 I used for the sim. Not to rain on your parade but I think you will do real good to get a low 12 sec pass.

My friend's 327 powered 69 has gone 12.40 @ 108 which IMO is pretty impressive for a 3500lb car on the motor. That was with a 4000 stall and 4.11 gears.

I get, and you all know I'm the king of keyboard racing, 12.26 @ 108mph. It recommends a 4200RPM stall and 4.52 gear (or use 26.5" tall tires). If you advance the cam 6 degrees it gives 11.99 @ 109.7mph and your gear/tire/stall are almost right on the money.

This is assuming a set of good flowing iron heads 2.02/1.60 valves, 10.5:1 compression, 1 5/8" headers, 750cfm Holley, good weather at sea level and "excellent" traction. I've run quite a few peoples combos through here for sh!ts-and-giggles and it always seems to give about 2-3 tenths SLOWER times than what they've actually run.

Well, I have 1 3/4 headers, Dart Iron Eagles, 11.5-1 compression, 750 DP, @ Sea Level

Switching from 1 5/8" to 1 3/4" headers says you'll slow down to 12.16. This is because the larger tube headers bring your shift points up 400RPM (says 6000RPM with 1 5/8" and with 1 3/4" it says 6400RPM) Dragstrip Plus gives 463HP and Desktop Dyno, which uses flow numbers so it might be a little more accurate, says 497HP

oops double post

Well, I guess there is only 1 way to find out which will be very soon........Also I switched 5/8 to 3/4 cause I got a set of Hooker SC's at a price I couldn't refuse plus I'll be running spray also...
