Turbo
Volumetric Efficiency Displacement Restrictions (IM, exhaust, TB, piping, air filter) In essence it all boils down to mass flow rate (lb/min). PSI is just a relative form of pressure ratio, which is only part of the equation. I'm currently running at 12psi...which I'll admit is fun, but not nearly as much fun as FRTfun is having. That pressure ratio at redline on a 1.6L with my little peashooter is at the far edge of the efficiency island, over the 60% line. This yields a 1.4 DENSITY RATIO which is a much better determinant of power. FRT has more displacement, and a turbo which flows more and is more efficient where we are operating...much more efficient. If you want to start a "12psi Club" I'd be happy to join and feel like I'm awesome...but if it were a "200whp+ Club" I'm afraid I'd be excluded, like I was through most of junior high. |

12 > 8. That is all that matters.

Me first :)
|
224 kpa
|
Will be there mid next week once I install the clutch....I hope :)
|
Started and broke in the new buid today, loved 7 psi and is begging me to join this club after i fix the pass side wheel bearing.
|
No worries, you will get a ride, I just have to make it out to one of these meets when the cars finished.
