guys need your help on this
ok so here it is what kind of compression ratio can the m113 hold before i blow a head? also someone told me i can use two head gaskets to lower the compression but i dont know about that, sounds a little iffy? so what do you guys say.

for N/A motor 11.5 comp is about the limit for 93 octane gas forced induction you should run 8.5-9.0 comp.
stacking head gaskets is not a good idea i dont think it would work out.

Stacking head gaskets is not a good idea, just have one custom made and if you want to run high boost I would keep it under 9:1

Ted Baldwin swapped to a C32 pulley on his W210 E55 but it required changing all the pulleys and a new AC compressor. Heres a link.

You can run alot more than 10PSI with 9:1 CR. I'm running ~8.5PSI with stock block of 10.5:1 CR. Sounds like you have big plans, who is going to tune it for you?
