Re: Max boost on stock LS rods? (gigantor)
Depends on the charger and what kind of tuning you're capable of. I've seen a turbo single cam that made 300hp using LS rods. My stock LS took 9psi for a long while from a T3. It's in the tuning.

I was running 14psi on the stock bottom end. But an accidental boost spike ended the piston lands.
Before she blew I was pushing 272 whp with 11.8:1 a/f ratio.

Re: Max boost on stock LS rods? (BlowOff)
Here's the buildup:
-wiseco 8.5:1 pistons (ultra-lite race version) .20 over
-Mr. Gasket head, intake manifold and exhaust manifold gaskets
-ARP head studs
The block has been cleaned, decked and bored .20 over. I had all the bearings replaced, the oil pump rebuilt, timing belt and water pump replaced and had the crank cleaned and rebalanced.
My car runs the following setup:
drag gen 3 turbo, deltagate, rc 310cc injectors, walbro 255lph fuel pump. my car is currently set at 14psi.

How long were you boosting at 14psi?

Re: Max boost on stock LS rods? (gigantor)
Ive heard as much as 350whp.. but there are always freak motors and freak set ups.. just curious, why did u go with 8.5:1 pistons? are u planning on running high boost on pump gas?

Re: Max boost on stock LS rods? (DIRep972)
I wouldn't even chance it with the stock rods. You're almost 90% built...why not just wait and get some GE rods or something? With that much money invested already, I would definitely wait for some rods.

Good luck with the build. Who's doing it?
