what are your goals??? i say 15 psi to stay reliable. you can run 25 if you want, just need good tuning.

Re: What would you consider to be the psi limit for my motor? (Bspec18)
Injectors
CPR 850cc
Walbro 255 intank
Goals:
to be able to run mid to low 11's
What ever it takes to hit... 11's
Why is it ok to run more psi without a block gaurd ???

so you are saying the motor can handle 450whp and psi is just a variable to reach that power?!

im saying that with a good tune the 425-450whp level is relatively safe for your motors build. I wouldn't push it much past 450whp....it could take 18psi, 20psi, 22psi, etc. It really doesn't matter.

Re: (Bryson)
Ive seen guys with simliar setup to urs, with no block guard. Stock sleeves. Boosting 25psi !!!! I assume, jus to get a good Tune. You will be good. Im sure low 20psi will be Definately safe!

Re: (ExcelcivicSi)
i say you would be able to run more boost without a block gaurd since the block gaurd causeshotspots and detonation. it also causes the wall to warp. because of this the block can not be boosted as much without the risk of detonation and warpage.
the bock gaurd doesn't really do any good. it doesn't prevent anything your motor will see if your only running 25psi or less. even highger than that, there are little to no side loads. even if there were, the block gaurd doesn't even reinforce the walls at the right place. the place in the motor that the motor would see the most side wall force is actully about half way down the sleeves. this is why the only sleeve maker who uses block posting on thier sleeves that does it right is golden eagle

Re: (Bryson)
The Ideal gas law ... cant wait for the EFI course at riverside.. 
Any ways, thanks for your responses, ExcelcivicSi – I’m located near Napa, to the block guard question should I consider not to boost to high since it might knock but I will be using c16 gas during tuning or motor sport 109, so should I boost high to achieve the 450hp bench mark ?
