this is a turbonetics kit on a stock sleeved gsr 81.5mm motor. it has aftermarket 9:1 forged pistons but stock rods and rodbolts. im just getting some opinions on what the safe whp range would be for a setup like this.

 

the <U>general</U> number you will get is to "keep it under 300whp"

I have to agree with Dunc, wouldn't take it over 300+hp.

 

yup keep it under 300... why not forged rods ?!?!?!

 

I agree. Right around 300 is where you want to limit.

I did this also, just didn't have enough $$ after I blew up my GSR to buy rods also (few years ago, rods cost more then)

I put arias 10:1 pistons in with stock rods/bolts.

I ran 10psi on log mani, 2.5 dp and made around 280whp.


I ran this for over a year and then tore the motor down for a complete build cause now I had money. Rods still looked ok when I pulled them out, maybe a little discolored from a lot of heat but thats it.

 

It's mind boggling why you wouldn't put some Eagles in there when you tear the motor down to put forged pistons in

 

this isnt my car, its a friend of mine, who ran out of money fast....
