Having 11:5 pistons and now wanting to boost but not wanting to change out the pistons-can it be safe to boost on that high of a cr? Ive heard ppl use a thick gasket to lower the compression do any of those gasket kits exsist? any info is greatly appreciated

 

thicker head gaskets do exist but i dont think that would help you. I wouldnt boost with compression over 10.5-1. and even at 10.5-1 i wouldnt go over 7 psi. You could run like 3 psi but thats kinda a waste

 

You can run that much compression. It just makes the setup harder to tune. If you are going with a good fuel management system and you have proper fuel supply ect and have it tuned, in theroy is should last for quite some time and make some nice #s... Tony the tiger is running over 1 bar of boost on his 11:1 CR setup in his teg and it runs fine... and hauls butt!!

any more questions- PM me.
