Wives tale. Most of the full bridge, 10K rpm engines in local race cars around here are only dipping 280ish to the hubs. Some halfie's landing anywhere between 220 and 250.

A custom intake with less porting (and presumabley revs) won't net an extra 40% increase in peak power, assuming 200 to be the practical peak benchmark for a well done streetported 4 port.

If you really wanted to do something experimental, try my next project.

300-350whp max, small turbo (T04-E 57 trim likely.....) with straight water AI.......................................on 87 octane. I don't care what type of block you use, but has to be low grade fuel. That's what I'm planning to do with my recently acquired FB, one day.......one day.

Turbo engines can be reliable. Certainly not as "bullet proof" (ie. as low powered) as an N/A, but don't think you can't just because people have problems....its no reason to stay under the 300whp mark
