awesome harlan, what did your timing look like on that run? 100 octane right? oh do you have a ported a TB? and MAF? i think these would help with with a translator, more airflow is always better.

<img src="graemlins/gr_bs.gif" border="0" alt="[bullshit]" /> You know LS1s cant make that kind of power on less than 25+ psi...ask the buick guys <img src="images/icons/wink.gif" border="0">
Don't think we aren't gonna try to pick your brain apart for all the little things you've done to tweak that thing to such awesome numbers. Seriously..Awesome job! Tell us about your timing curvee. I am thinking its shaped like the letter "U"

Wow, those are some nice numbers Harlan. I'm hoping for something like that hp range when I finish my engine.

R U bringing timing back in after your tq peak? Even though where you let off is higher than my peak numbers <img src="images/icons/tongue.gif" border="0"> I bet you would love to keep it from falling off so much. Or is this purely the intake restriction your refering to?

Awesome numbers!!
Imagine that setup on an all bore ARE 393 with S3 heads and decent cam!! <img src="images/icons/grin.gif" border="0"> You would need 55# injectors, custom fuel and custom tune but it would be SICK!
Cheers,
Chris

55lbers for a 396CI/S3 Heads and real boost..
No dice..More like a FAST SEFI W/WB and 83lbers...


Turbo that is a mean setup u have there
I bet Chris is right,With a big motor and S3 heads u could make 850RWHP to 900RWHP

Wow nice numbers!!!

On the intake restriction. Let's say you got the new Weiand alum manifold and extrude honded the crap out of it. Or you got that LSPyder intake... I assume that would greatly reduce restriction and give you gobs more power?????

Default Re: hmmmm, Turbohawk + dynojet + 12+ psi

Right now

I run SVO 42's at 58 psi base pressure. so they are basically 50 lb/hr.

I'm in the process of getting the stock PCM setup to run low impedance injectors.

I've got a few tricks up my sleeve, so no need for DFI yet.

i'm not sure where the restriction is in the system. but above 5k i can't get any more air in the motor. All three pulls i made end up at the same line from 5k on out. The were made at 10 psi, 11 psi, and 12 psi.

The initial hit in the 660 tq pull was about 13 psi, then it leveled off to just under 12.

The basic plan for the winter is

stock cubes, stock block, stock crank. good rods and pistons, 9:1 CR, mild work on some LS6 heads. a reasonable cam, still considering the Hot Cam to try first. BIG front mount IC, dual core radiator.

sumped 98 tank, and a HUGE fuel system <img src="images/icons/grin.gif" border="0">

Harlan I'd get with someone like Harry at Precision Turbo to pick a cam. Or maybe Tony Dequick at CAS.

Uh, can those turbos even flow enough air for 900 rwhp?

nice numbers, I pulled 691 RWTQ on my N2O setup a couple weeks back and that was with the bottle almost all the way closed.

I think your major restriction is simply the stock cam.
A hotcam with a blower might add around 60hp over the stock cam with 10psi. But I am not sure how it will work with a turbo.
