ZZP 2.4 Max Power Testing
I wasn't sure what section to put this in. It's a forged 2.4 bottom end, but running an LSJ head, LSJ ECM, LSJ turbo kit, etc...
Anyway- we finally got a clutch for Ryan's car so we could get started on the 2.4 max power testing. Ryan is still running the S366 billet turbo from Bullseye. We made a few pulls tonight getting things dialed in and so far all is well. At 23psi, it put down 602whp std, compared to 533whp at the same boost level for the 2.0/S362 combo. We turned it up about 3 psi and picked up 50whp. Another 3 whp was good for another 50, putting us close to 700. At 30psi, it put down 719whp std, and that was where we quit for the night. We need to change the wastegate spring or get a higher pressure boost control regulator. Testing will resume tomorrow!

Hey Matt, what are the advantages of using the lsj head on the le5 block??? Or did you just do this because Ryans head was already set up for this turbo configuration? Oh GREAT numbers btw.
