Is the car in your sig the one that ran that time? What was the DA? 10,000?

Philip Pugeau

Yes, the car in the sig ran that time. It was the best out of 9 that night, with 12.4's the other times. Trapped 110 one run. Not sure what the DA was, I'm in Orlando and it was about 80 degrees.

I could be wrong, but something seems really off about your times, and the numbers in your sig. I'm running times a fraction faster than that with a stock cube, stock internal, bolt on LS1 with a 4000 stall. With the list of mods you have in your sig, I definitely think your car should be pushing higher numbers, and should be getting into the 11s at the track, especially on drag radials.

The stock exhaust could be choking you off maybe? That's the only thing I can think of. Even a high DA shouldn't limit you that much.

look at the dyno numbers at the bottom of his sig guys, its not making nearly the power it should for the internals - those are bolt on numbers...

I agree. Your car should be moving down the track faster then this.

I forsee a tune in your immediate future

Sales1@Texas-speed

Yea the time and mph are down for sure, and if the numbers in the sig are current there is definitely some work to be done.

I can understand the high ET but the MPH never lies and yours is way low unless your letting off early.

Are you running it right through the traps?

Philip Pugeau

Wow, all kinds of replies!

Well, to start off, the 383 was really held back by the stock ls6 cam and stock exhaust. That's why it made 330 at the tire. Besides the 383 bottom end, it was pretty much a bone-stock ls6 top end with no bolt-ons whatsoever. It has been thoroughly tuned by Geoff at Next Level Performance.

The 3500 is a very street friendly, low STR and tight converter. That best run was launching at 2000 rpm and somehow getting it right for that 1.7 60'. Besides the stock struts, all other suspension mods should help with the hookup running a 4.10. First gear was over in an instant, but made up for it with an incredible blast of take-off.


Here's all nine track times that night, including the failed launches:

In addition to the above post, I have just recently had a cam and exhaust installed. That woke her up! We'll see what that does at the track next Friday.

-Comp Cams 230/236 114+4 XER
-American Racing 1-3/4" LTs, 3" collectors, 3" y-pipe w/high flow cats, 3" manual cutout
-42 lb injectors
-Dual Valvesprings w/ti retainers

RED is before the cam+exhaust. BLUE is, of course, pretty awesome:

You need to get bolt-ons and a cam! That should be an EASY 11 sec ride.

edit: you snuck that lost post in on me. Now it will run 11s.

According to drag times d.a. was 698 ft. Per your timesheets. My bolt on car traps the same as that with 1800+ d.a. hopefully with the new stuff your times will get you in the low 11s here you should be

Philip Pugeau

Yep. That's what happens when you plumb a leafblower through a garden hose. It just ain't gonna happen, no matter how much tuning one does!

babbage1109

That's for sure. Lol. It should be on track now.

IT should post better times with the new additions. The original times were horrible for a 383 but they make sense after letting us know about the cam and heads you were running

Philip Pugeau

Not to get off topic and be moved into the " Dyno Guesses and Bench Racing Forum", but I've been guessing at 11.7 @ 118, just to throw a number out there. That will include running 3rd gear out to 6500 rpm at 110 before clicking into OD. That's how I ran that 110 trap speed, originally.

That's what my roommate runs cam only with a 3600 stall

But with a lot higher da

Philip Pugeau

Yeah, I've heard about these cam only cars making big numbers and respectable runs. Most of what I've spent is on overbuilding to survive my right foot. I'm sure everyone can understand that! Not to mention all the parts I have broken already, ie stock 10-bolt w/4.10 gear, and stock valvesprings that ruined the original LS1. good times
