Reading through this, this is all interesting stuff.

I read through all of this rather quickly but I did not see where anyone mentioned the FWD advantage. FWD powertrain losses are generally much less than that of a RWD powertrain. Powertrain loss on a FWD car may be 10-12% vs. 18 to 20% on a rwd car. Obviously varying from make to make. I think some with dyno experience with mulitple cars can give you more accurate info, this is just what I have always heard. You are changing the direction of the power and it creates more a loss, not to mention more moving parts.

I think this needs to be included in any calculations where we are looking at stock hp vs. improved hp and weight. Your thoughts?
