10:1 comp max boost
hey guys I am new on the forum. I have a 1998 nb mx5 with a rotrex supercharger. Its on about 9.5 psi and makes around 220hp at the wheels. The motor I have at the moment has a 9.5 compression ratio as it is standard. I am thinking of building a 10 compression motor with forged internals and running about 10psi through it. Will a 10 compression motor be able to safely handle 10psi providing its tuned properly? thanks guys.

we need a sticky about how boost is irrelevant.
I'd say you're safe up to 250 rwhp if you have an INTERCOOLER.
otherwise, call it 225 before the intake temps are too hot to be safe. *shrug*

I use an '03 10:1 bottom end and a tiny GT2554R running 10psi. IATs are good with an 11x11x3" FMIC. Your Rotrex puts more heat into the intake charge but the fuel you have over there has better detonation resistance.
A knock sensor and EGT with proper monitoring/management are a good idea.

im running 10-11psi on a stock 2002 Motor with no problems. Tuning has a lot to do with how much power you can make on a given motor. For a "built" 10:1 comp. motor you should be able to make more then enough power.
BTW, its nice to know that JR wasn't blowing smoke with showing those kits. Im really curious as to what they're going to get out of them.
