hi
i did alittle bit of research about this blockguards things for my block and I was woundering how much psi would u put on a all stock gsr engine with blockguards but with a 9.1 cr and some fmu and injectors

 

Umm u shouldnt be using an FMU with upgraded injectors 1st off and if u were to use an FMU u would have to worry about that b4 the block guard or ne thing else...

 

you need to research for a few months before you buy anything...

 

PSI has zero relation to sleeve failure!

 

with an FMU it`s not recomended to go more then 9 psi of boost . and with an FMU and 8 psi it`s recomended for you to leave the factory injectors .

 

ive seen up tp 25psi but i wouldnt recommend any more

 

Listen guys.......<FONT SIZE="2"> PSI has no relation to sleeve failure by itself</FONT>. NA guys crack sleeves so, where is the relation? Peak cylinder pressure and the rod angularity that this peak pressure occurs are the deciding factors. A better question would be, "What WHP can my stock GSR sleeves handle".

your stock pistons will crack before your sleeves... get pistons before blockguard

 

I've gone 26 lbs on my Nuformz BG, but I'm also all forged internals too...

 

I built an LS motor for a friend of mine w/ just rods, pistons and blockguard and made 417whp 340 wtq on bone stock "LS head" @ 22 psi.
