Inliners International Forums General Discussion Blown and Injected Building a 250 turbo for Bonneville

from some quick calculations, you are going to need around 20 psi of boost. maybe even more. that is to achieve the 500hp mark. this engine will need to be intercooled also.
the turbo needs to have a high efficentcy, like 75% and so does the intercooler.
also V8 rods are too narrow on the crank end to use.
