Does anyone know any good books about Carbs?
I really don't know a lot about them, and I'
ve always wanted to learn.

Why is lower compression better for Blowers and Nitrous?

Lower compression isn't better for blower or NoS applications, they just cannot live very well with high compression. The additional heat generated by the blower or No2 promotes detonation. Blown Alcohol engines use 12.5 to 1 and higher compression because the alcohol fuel runs so much cooler.

I've always thought blower motors liked less compression because with less compression you have more volume you can fill. The more volume (void) that can be "force feed" the more pressure can be created. Thats my take on it anyway, as it applies to street cars that is.
