Rouge, forgive me if I am mistaken, but from the pic in your album it appears as if the blower is pumping the charge "up" to the inlet manifold. If this is the case, I was refering to the blowers ability to push the charge up to the intake at cranking speed.
How much heat is generated on the blow side of the pump? that is some significant overdrive you have. I wouldn't dare spin my s/c14 that fast. Those little blowers are about 600ish cc's aren't they?
I have scored an IHI lysholm screw blower recently. But I can't decide what to put it on.
