So my car has just about every bolt on, with a cam. Just installed the LSX 90/90 combo. We're still thinking there is a lifter preload issue, going to swap out the 7.4's for some 7.35's.. anyway.. New numbers are 441rwhp/395rwtq SAE corrected. Im pretty happy.. but theres more in it. This is with heavy *** 17x11 TT2's with 315 DR's... and a crappy lid with a fucked up k&n filter lol. 100 shot numbers in my sig... dissappointing.

 

wanna give us a hint on what cam it is(sounds like t-rex) or specs? sounds like some good #'s...

 

its a TRex

 

what is the Trex cam?

 

see thunder racing ------>

Nate

 

242/248 .608/.611 110lsa..

 

yea didn't think the 109 or 110 lsa would do good on the gas.. made lots of nice tq tho

 

Nice numbers on motor. Sorry about the nitrous, but a lot of its going right out the exhaust valve un burned.

 

Can you post a graph?

Why "cam only" in quotations?

 

What gear and rear?

 

"cam only" means its a bolt on car with no engine modification(i.e. displacement, heads, forced induction), but just valvetrain and cam and the bolt ons.

 

Yeah I know, but most people do not put them in quotations unless there is a descrepency to the cam only rules. For example, 241 heads on a 97-99 motor.

 

4th gear, M6, 10 bolt with 4.10's (thats about to explode lol)

ill post a graph in a minute, i dont have a scanner, just a digital camera.. so quality may not be the best..

 

Run 003, is with SLP longtubes, ASA cam, and LS6 intake
Run 033, is with Dynatech longtubes, TRex cam, and LS6 intake
Run 041, is the same as 033, but with an LSX 90/90 combo.

 

Very nice. Looks like more and more people are putting down big cam only numbers with this T-Rex. I may look into this one after all. Now lets see some track numbers.

 

wHY Does the hp graph drop way before the 7k mark I thought this cam made its peak power at 7200???
Good #s though!!!!

 

I like how the ASA has more torque from 2500 to almost 5k with a LS6 intake Is that ASA cam for sale?

 

Hehe, the ASA cam was sold out of this car before it was even removed, lol.

NickcZ28- we're not quite sure why it falls off like this, im still thinking its a lifter preload issue. im running harland sharp rockers, 7.4 pushrods, and comp-r lifters... im going to try a set of 7.35 pushrods and see what happens...

 

Get rid of those damned HS rockers and put the stockers back on with the nasty performance mod. Thats a lot more weight in the valvetrain that you dont need and i would be certain that it's part of your problem.

Nate

 

Are the stockers that much lighter? I would think with a full roller rocker you would be better off. The Nasty mod? Is that where they change out the barings? How much is that?
