100% stock motor + boost TIME SLIPS!!!
100% stock motor + boost TIME SLIPS!!! so i havent seen or heard of many completley stock setups being pushed with boost so i want to see what other people are running!
i just ran the 1/4 mile at Texas Motorplex this past weekend
my setup is a 147k stock ls1 with a 4l80e and 3400 circle d stall
HEADS HAVE NEVER BEEN OFF!!!
i made my own truck manifold setup and am running 14lbs of boost from a precision 67/66 (small turbo but it spools fast)
and simens deka 60 lb injectors
stock returnless fuel system with a walbro 255hph pump
all tuned by me using hptuners
my first pass was as folows
1.696 60'
7.268 1/8 @96.51
11.368 1/4@119.44
second pass
1.682 60'
7.287 1/8 @95.89
11.379 @120.36
later that night i made an apperance at texas raceway in kennedale texas (1/8 mile track)
the temps had dropped into the high 40's
ran a 7.11 @ 97.7
and a 7.13@ 96.8
i'm not sure how long this setup will last but i'll keep running it like it is until i have an issue.
currently i've hit a 85% dutycycle on my injectors so i donot want to push them any furtur
anyone else running a 100% stock long block feel free to post your times!!!

Its in a full interior 2000 transam
And that is because the turbo is tiny
Most guys run two if these turbos as twins it dosent flow near enough air up top. Im planning on buying a second one as soon as i decide to build a motor.

97 mph in the 1/8 at ~ 3,800 lbs puts you around 510 rwhp. I don't understand why you are at 85% duty cycle with your 60#/hr injectors. It would be interesting to see your VE table, and injector flow values.
From what I calculate you trap about 15 mph higher than you would stock. That gives you right around an extra 170rwhp. So you're making about 12-13 hp per lb of boost. And if I'm not wrong usually people with some-what efficient turbo's are making 25 hp per lb of boost or so with stock-ish ls1's... Congrats on trapping 120 either way though!

Verdad Gallardo I know that a bigger turbo would help out. But i dont think the stock fuel system other than a pump and injectors would support 14 lbs out of a bigger turbo
I know the car could be running better. But for a 100% stock long block im pretty pleased with how its running right now
Its very consistent aswell!

ya ive pushed my 60 pounders to 109mph with my heavy turd and i still havnt turned on my second pump. i am spraying meth which im sure helps a little bit but 85% at that range seems high or you have it pig rich
so i havent seen or heard of many completley stock setups being pushed with boost so i want to see what other people are running!

ah!
i forgot about stock springs
they are absolutely holding him back
i bet a dyno pull looks all droopy at full boost like our truck
throw some pac 1218s in there for a cheap experiment, see how much faster the car goes lol

I am aware my pump is the limiting factor right now. The turbo is next on the list .
This setup was just a budget test to see how far i could push my 100% stock motor and nearly stock fuel system.
There are many upgrades i could do to make it better. But running 11.3's with under 1500 invested in engine upgrades. Im pretty happy with it for now until i finish saving money for a big build

I had a stock lq4 in my camaro with the on3 t76.I was running 14lbs car trapped 123 at pretty much the same weight.stock valves springs were definitely holding me back.car would start making real good power at 4000rpm then it would stop at about 5200rpm.
But fun none the less.
