Hello guys, I’m new to this community so any accidental guidelines I might break please forgive me. I’ve got a 2017 zl1 manual with heads, cam, headers, flex fuel sensor, rotofab big gulp, nw103 tb, alky control meth kit, stage x kong ported stock blower, low side aux pump, 2.3” upper, 10” lower. Made 905whp but burnt a hole in the piston while doing so. Ordered fore triple pumps and port injection to take care of the fueling issue. Pulled the motor and decided that I’ll up the compression ratio to 11.5:1 cause why not? Mo powa baby. Anyone have any experience doing this? What power numbers I’ll be expected to see? Might change the upper to a 2.175 to hopefully break that 1000 mark. Also created this to I guess “test pig” it for others that might want to take this route. Thanks!

Might as well do a stroker crank. Could do lt8 crank. More cubic inch and more compression with same piston and more power obviously.

Hmm, I’m not an engine builder, but most of the time I see people running lower compression than that so they can run higher boost and more timing. Maybe on E85 you can get away with it but I’m not sure on that. I’d talk to a couple of professional engine shops experienced with the LT4 before going down that higher compression road.
