Hello all,
I just finished my build on my 2001 Vette mods are.

PRC stg 2.5 LS6 heads w/PRC springs
Torquer V4 111lsa cam
Fast 92 w ls2 ported intake
TSP long tubes w/ cats and borla stingers
SLP underdrive pully
42lb bosch injectors
Monster Stg II clutch
Mail order tsp tune
Z06 springs/shocks/sways

It is up and running strong haven't gotten on it all the way as I'm still breaking the clutch in. Hoping to throw it on a dyno jet here in the next 2-3 weeks.

It feels strong and pulls hard anybody have any guesses on what dyno numbers it will put up? I cant find any dyno charts for the Torquer V4 cam.

I don't have an accurate guess, but I would say mid 400's on a dyno jet.

Solid build, wish I still had play money

01badvette

That what Im thinking somewhere around the 450s,
Im more curious about the Torque curve on the Cam it feels pretty solid all the way from 2500 and up.

dbgoodwin

When I'm back in the game I'll be looking for a nice, high torque cam. Honestly I'm happy with my 380ish whp, but I want the Cammed experience haha.

425rwhp, 400 torque.

Seems a bit low for a dynojet. Not that dyno numbers even matter. I know my car is a good bit quicker than a lot of other 376whp cars.

I'm not really hung up on the Dyno numbers wherever they trend high or low, its more of just a curiosity thing I just wanna see were they trend in comparison to the bolts ons before. With just the bolts ons (pre heads and cam) I was 355hp/371tq on the last dyno run on a dynojet. I'm going to bring it back to the same place for a better comparison.
The Cam really does push you back in the seat now from 3K on up and great all around torque, so judging by the seat of my pants it feels like it def gained a significant amount of under the curve and overall power.

Could be. I've been at this a long time. Depends on what cars you're comparing to as well. I've seen a LOT of modded C5s and its not easy to hit 450rwhp with a NA LS1. My first round of mods were almost the same as yours. I had a slightly different cam, FAST 102 w/ported LS2 TB, milled and ported 243s, XS Power LTs, 25% underdrive pulley, Vararam, Lunati dual springs, 36# injectors and a professional tune on site and made 420/398. I was running an A4 so you'll pick up some since your a M6, but the numbers won't be that much different. To hit 450rwhp, that means you need to be making about 530hp at the crank taking into consideration a 15% drivetrain loss with your M6. The A4 has about a 17%-18% loss. Getting to 400rwhp isn't too hard, but that last 50 is tough. GL with your build and let us know how it turns out once you get to the dyno.

She is going on the roller Friday April 22nd will have the dyno sheets posted up after

chassed

Can't wait to see how it does.

red03vette

i'm in for results, sounds awesome!

01badvette

Sorry for the delay my dyno time got postponed, Hopefully can get rescheduled in the next week or two.

My guess is 435 400


I am getting 429 and 395 with the PRC stage 1 heads and the TSP228R, LS6 manifold, XSPower headers, under-drive pulley and a Vararam.
Dyno Jet dyno tuned by Cartek.

01badvette

I hope my cam with more lift and duration along with the fast 92mm and stage 2.5 heads are worth more then 6 HP over your setup, or I spent a couple thousand dollars on nothing. We will see tho.

warren s

You know what they say, Speed costs money - how fast do you want to go?

When is your rescheduled dyno day?

01badvette

I hoping for May 20th the car has a baseline solid tune on it now. The local speed shop I'm using for the tune is more or less just doing it as a favor towards me putting it on the dyno so I'm kinda at the mercy of his schedule as well. Hopefully within the next couple weeks tho.

warren s

How many miles are on your engine?

01badvette

The motor has 80kmi on it. I did baselines pulls with just LT headers and air intake and was at 355hp/371tq. The bottom end still has good even compression and solid oil pressure even before my high pressure oil pump. Going off of what TSP said and my tuner I should see around 90-95 rwhp gain from where my baseline was. I know the seat of my pants tells me it was a huge increase over where I was it pulls substantially harder. I'm going to the drag strip today hopefully I can get a couple good launches and I'll post up the results.

warren s

Thats a very strong baseline for just headers and an air intake.

My best time with just the headers, Vararam , LS6 manifold and a tune by ECS was 12.611 at 110.48 , I am hoping to be in the 11s next time. My driving skills at the track also have much room for improvement.

I have 30k miles on my car
