Never said exhaust vacuum wasnt measured by anyone except Honda owners -- said in the case of crankcase exhaust evac setups I havent run across any actual measured numbers except from the honda crowd.

The thread and topic was about crankcase evac, not exhaust design. Besides, we have a big blockage hanging off the end of our manifold (this is the turbo forum, right? *doublechecks*), that kinda kills exhaust pulses post-turbo, no?

The question was that a muffler creates to much backpressure and it overcomes the Bernoulli's effect -- my post was intended to point out that the people who say this are old school v8 owners who run large, chambered mufflers. The turbo import owners who run straight-through mufflers have proven that the exhaust evac setups do work with this type of muffler, and have measured the vacuum to prove it, in both hondas and high hp single turbo supras.

Youre smarter than I am though, any input on the exhaust evac setups as a means of reducing or eliminating crankcase pressure? Short of a vacuum pump, Ive been led to believe it is the best method, especially on a turbo car where you have to still have a means of adding vacuum to the crankcase and boost keeps you from using the intake as a source...
