425 rwhp is my magic number that I HAVE TO HAVE as that gives me 500 at the CRANK and I NEED 500 at the CRANK to keep me away from that new Z for several years. I have all the aggressive bolt ons listed in my sigs and for now must likely will stay with stock LS6 heads (as they flow great and don't think $2,000 is worth a few more rwhp).

I know several here have hit that magic number i am looking for and I the the LGM G5X3 is a STOUT cam. Keep in mind this is going to be a daily driver where i put on between 12 to 15K miles a year on my Z and i need a RELIABLE SET UP!! I like the LOPEY HOT ROD SOUND and know others have had success with grinds in the area of 232/234, .590 to .600 lift on a 112 or 113 lsa.

I don't want to flycut the pistons and was wondering what the new bad boy streetable cam for stock headed LS6 motors are these days and if you hit the numbers I am looking for on a bolt on Z please let me know the cam specs by way of this post or IM!!

THANKS GUYS &LET THE SICKNESS BEGIN!!!!!!!!!!!!!!!!!!!

I have a cam that will work very well on your Z-06 and should get you close to the numbers you are looking for (it will be hard to do it with a stock intake and TB). As for your heads we could do the port work needed for around 1500.00 and the gains should be in the 40rwhp range.

Thunder Racing just came out with a new line of Cams. The first is the TRak cam (Thunder Racing ass kicker cam):

231/234 .643/598 112LSA (+2).

It has ideal valve events for a 346 and will make more power than any other cam in it's duration range. It has slightly less overlap @.006" than the FMS F-13, but lots more duration at .200" lift. It's a bad dude. If you run a good spring, reliability should be good. The lobes are new and designed to pull very high rpm. They have the cam in stock now.

Flycutting pistons when running stock heads LS1 or LS6 is not necessary.

That is an interesting grind.

I definately recommend going with the G5X-3. I buddy has a 2002 Z06, M6, with bolt ons and put down 422 RWHP on a Dynojet. If he had his TB ported, he would easily have put down 425.

There is the new LPE (lingenfelter) GT11 cam

215/221 .631/.644 118.0 CL w 1.7 rocker

Said to make 500 hps on a LS2 with stock exhaust and cats.

the ls2 is also around 20 more cubes...

The grind we are using is based off of renegade lobes. On our dyno it has made more power than any other cam only car we have ever seen. When mated with a set of ported heads it made more power than any other HC we have ever seen.
Price is 375.99 plus shipping. I do have one in stock.

Specs?

That TRak cam looks VERY interesting. Not a huge duration cam. That might be just the upgrade for my little 221/221 T1 cam in my A4 car. Talking about revving high though, that might mean tearing into the engine and replacing some rod bolts. What kind of powerband are we talking about Patrick?

The TRak cam has an intake valve closing point of 45.5 degrees ABDC @ .050" meaning it will make peak power right at 6300 with a 346ci LS1. The ideal valve events mean it will carry power easily to 7000, but you will not have to turn it that tight to make the power you need. It should be a beast of a cam with better idle than the F-13.

Brent B send me the specs too. I have the money in hand for a cam. P.M. me. Thanks

I don't think so, I've seen t-rex cams on graphs here on this board peak at 7000. In fact, I called comp and they said it shouldn't peak until 7200-7300 with the right intake/exhaust. And just so you know, 425 rwhp is not 500 crank. It only takes about 40 horsepower to turn the drive train of a z06. Add an aluminum flywheel and you have even less. You need about 450-460 to be at 500 crank horsepower. There are no percentages because that would mean that it would take more horsepower to turn your drive train just because you added power which makes no sense. I suggest heads and cam.

The T-Rex should peak higher than the TRak cam, it has an intake closing point of 49 degrees ABDC. That said, the intake manifold becomes a limiter to the LS1s peaking a great deal above 6300 rpm. Some do, but the runner length of the intake dictates much of the level at which peak hp and torque occurs.

The tech at Comp is looking at perfect case scenario, not a real world LSX application. With an intake with shorter runners to better match the T-Rex, the motor probably would make peak power above 7000, but with the LSX manifold, it's more in the mid 6XXX range.

Just give it a sloppy shot of the juice.Thats what i do t

Its been said before that the drivetrain loss is verry debatable on weather its a percentage or X amount. Im my personal opinion 425 should be pretty damn close to if not 500 crank. I highly doubt with IRS that the vettes loose only 40hp through the drive line.

My cam is going in today, I'll let you know how it is.

I agree as the industry standard is 15% drivetrain loss for manual tranny C5s. That being said, let's not turn this into a pissing match about drivetrain loss etc. The thread is really geared on what street cam will give me the most power on a daily driven Z (without losing low end torque andwhere a nice lope and hot rod sound is what i am used to and enoy!!!

Sorry about thats, I do agree that the G5X3 or Majic stick would give you what you were looking for. Other cams are the HPE "S" cam, it made 430 in a friends car here in houston, ill see if I can catchin him online so he can reply to the post to give first hand advice about it.

I made 404RWHP through the muffler and a pretty quiet one at that with just bolt ons and no pully..233\233 .598\.598 112+2 ...most of your stock Z06's hit 345-355 at the rear wheels..hitting your number should not be that hard..
