I think you're failing to recognize how inefficient M90s are. Or did we start a new conversation about stroker motors?

Sounds like an awesome idea.

Like said the reason to open the exhaust up is to allow for more airflow and help prevent knock. It's been proven even on stock vehicle that it will remove some knock retard with more exhaust flow. That is a better solution than removing even more timing and increasing EGT's and cylinder temps.

Weird how the whole N/A compression with a supercharger thing was already covered... That's a completely different ballgame.

95% of people with a supercharged 3800 will not ever outflow the stock manifolds.
