5.2 Predator Block

[IceMan706]

My gen 3 5.0 block is finally on its last legs definitely thinking about going with the predator block. The car currently has twin turbos and a fore dual pump fuel system w/ a built t56 which compression ratios did you all go with really deciding on the 11:1 but it’s strictly a e85 car so should I go back with the 12:1 ratio?

Higher boost levels with 12:1 compression is a lot, even for E85. Not saying you can’t do it but you’ll want One Ethanol S or R. I’d stay 10.5:1 or so IMO.

How much power will you make? What size turbos? How much boost? What's your tuner say?

I have a Predator 5.2 in mine. I stuck with factory compression ratio in mine 11.0:1. Has only seen pump E85.

No. Don't plan to either for my power goals.
