First off I have tried it and it DOES knock the power way down. Almost 1000rpm in Fox 36X and even more in a Johnson BB. The exhaust is under pressure (remember muffler pressure?) and that pressure is always there and the gas is forced into the case by that pressure and there is a pretty good vacuum in the case from the induction. That vacuum is what made sub piston induction work in the first place. A shot of air was pulled in under the piston at TDC. Both lead to a fair amount of contamination of the incoming charge. Like I said, I have done it.
