I've been throwing this question back and forth for awhile. In the future I plan on building a 3s. Most of the crazy 3s builds I've seen are running around 22-24 psi with a lowered compression ratio. If you had the choice, would you rather a)lower compression and add more boost or b)keep the compression ratio at 8.5:1 and limit the boost. Or would you say that you'd get the same result either way. Personally I'd go with option A. But I really don't know whether one or the other is more or less hazardous. What do you think is safer,,if either?

stock compression isn't dangerous for a FI application. The danger comes from running pump gas at those levels. Is this going to be a street car? drag? what applications? and what are your hp goals?
