FAST LS1

iTrader: (2)

I'm wondering what the highest SAE corrected dyno is for a completely stock internal NA LS1?
No cam or valve springs to raise the redline, just bolt-ons. I'd like to know what mods produced the results also.
The highest I remember seeing here is in the 350-360rwhp range and was a full bolt-on car.

Edit: I'm going to change the title to reflect the highest hp reported as the thread goes.

I've got 354rwhp and 367rwtorque with just bolt-ons in sig.

If the LSX Intakes are any good I might make more.

The car is also still on the stock tuning, and I have a descreened stock maf.

it will be an M6 car most likely

LTs with a good flowing exhaust
Ported TB
LS6 intake
and the other usual bolt-ons

But why does it matter, I bet you can show me a stock internal car that dynos 350 rwhp and I could probably still spank it out at the track even though mine only dynos 314

Mainly I'd like to see what setups are the best for hp and what a full bolt on car maxes out at.

362.5hp and 372.7ft-lb tq

-Ported Throttle Body
-Descreened MAF
-MSD Wires
-NGK Plugs
-QTP Stainless Headers
-QTP Merge Collectors
-QuickTime Electric Cutout
-QTP Off-road Y-pipe
-Speed Inc Dynotune

I still haven't bought an underdrive pulley either. You could also get an electric water pump, but since I take the car on road courses, that's probably not a great idea for me.

Do you happen to have a dyno graph absolut_speed?

Also any info on gains from the dyno tune like before and after dyno numbers?

Mine made 351/361 bout 3 1/2 yrs ago running through Macs, 2.5 Ypipe, full exhaust, and LS1 intake. Would have been interesting with a set of longtubes, LS6 intake, and a tune....My lil 98 shortblock was a freak

lt's wouldnt have really helped on a stock car but the intake would have. did you have a tb or pulley

i think i have around 360 with a stock rear with the addition of the pulley, tb and few other things

I know for a fact w/ a set of LT's, 3 inch Y, LS6 intake, and a small tune the car would have made 10-12 more. Oh well, little late for that now

You are a freak according to the local zoo animals.. Now start posting new dyno #'s...

SMOKIN01TA

iTrader: (10)

i agree, i would think the intake and a tune would have done that.
i would like to know what i could get if it wasnt so rich with the lt's, just not willing to spend the money to tune a stock car.

As a matter of fact.... The two lines represent before and after the dynotune. (Forgot to mention I have the SLP OEM lid that came with the 345hp option)

SMOKIN01TA

iTrader: (10)

oh, so you have a dyno tune, its good to know i can pick up that much with a dyno tune

Wow absolut_speed 18rwhp from a tune

I'm going to change the title as need be to update the highest rwhp reported in the thread so people know what they have to beat. I really doubt anyone is much higher than the 360's range. I'd be surprised to see anyone in the 370's.

Like I said earlier, it's a stretch with just a pulley, but a pulley and an electric water pump would do it for sure, at least on my car.

Holy Crap, M6, My TR 224/224, Long tubes, Lid, Offroad Y, Catback, Predator tune, 10 bolt car only put 370 RWHP and 363 TQ. Good thing is my TQ curve looks flat as an ironing board I dont dyno high, but its good enough for low 12.0's
