Hey all, need some help for a uni project. I need some method of limiting boost, possibly at 1psi upto 7psi (though i doubt we'll use it more thtn 4psi max.). Its using a supercharger so we cant use a waste gate. What options does this leave me with? Bleed values? Boost controllers? I know little about these and was wondering if anyone could shed some light? we're going to be using a centrafugal type compressor (same as a trubo) which wont boost till ~20k rpm, but then will run all the way upto probably 100k. this means that the boost isnt going to be constant and so it cant just be leaked off at a fixed rate. We need to be able to change the amount of boost it holds easily as we'll be running it probably at 3 different levels throughout the event it will be in.

Anyone got any ideas?

Cheers
