Update: Now a build thread.


400whp isn't cutting it, so I'm finally going to put a cam in my car.

I would expect that without the FAST 102 on an off the shelf cam. I'm betting 445/420.

This is now a build thread, the fuel system has arrived and the cam is being ground.

My guess is 439hp/421trq.
BTW, instead of using a OD alt pulley I'd recommend just bumping the idle up to 900rpm.

I already bought the OD alternator pulley, plus my whole goal with this car is for it to be the ultimate heads/cam daily driver. A 900rpm idle just doesn't sound like it fits the description.

If you're going back to the same magical dyno that you hit 400 hp/tq with 3.91s then I will say probably 470ish.

If you go to a more realistic loaded dyno you're probably only going to hit 440 at the most with some 410 tq.

We've established my car is slightly stronger than your average GTO. I don't know many other GTOs with coated stepped headers and a FAST 102 on the stock cam. Somehow, because I made a whole 10-15 hp over a ported LS2 intake and pacesetters the dynojet reading is fake. This is the same Dyno that read 317whp stock with a hacked crapmaster exhaust and 365whp Intake/Exhaust/Tune. If you want to accuse Lethal Performance SATX of bullshitting the number be my guest.

Dynojets are usually known as being a bit friendly, maybe youll make 450whp on that dyno but on the street your car will be a 430whp car

Well that's one point of view, but Dynojet seems like the most common around here and thus the standard. People usually say the opposite: "It's a Mustang dyno, so it reads low." Those are really the 2 most widespread choices, and Dynojet seems more popular around here. Also, from what I've heard it's much more difficult to manipulate a Dynojet like you can a Mustang.

It really doesn't matter, the car makes power. Yes there's variation between dynos but do you think it's a 20hp standard deviation? Whenever somebody posts up a dyno number that's slightly higher than average people always say the dyno must have been rigged. Doubt it. Forget what's actually in my setup. Look around there's a thread here with a 415rwhp LS6 Z06.

my guess is 460-470 ... i mean there was a GTO that just put down 475 wheel with just a cam and a fast 102 , that RPM did in delaware
