i know the ringlands are bound to go out but i was wondering if i will be able to run 10psi. my fuel setup will be rc 650's, walbro fuel pump, and p28/uberdata. is 10psi the max hold on stock h22a bottom or should i go lower? i'll sleeved it, throw pistons and rods in the future.

 

A, A1, or A4?

the A1's have stronger bottom ends than the A4. Not sure about the plain ole A's though

 

i'm running 8 lbs on my jdm h22a (closed deck) using fmu/450cc/walhbro 255/fpr/vafc hack.

 

A

 

I think 8 is a pretty good to start. keep adding fuel/boost until something breaks. Thats how you find the magic number

 

why are you using an fmu, fpr, vafc hack all together? first off with the hack i thought u didnt even need the fpr let alone an fmu with it? does it run better with the fmu and the hack. that doesn't make sense =x
