you only answered the second part of my post. As for the girdle, what about a street motor that revs high, like most built ve motors. Surely the girdle is best kept in those instances?

Uhm so did you huh SR Romes.

I knew about the windage tray gains, but I never really gave the girdle vs windage tray much thought. To me the girdle's benefits always simply outweighed any reason to possibly remove it.

The girdle makes the oil bounce back and forth from girdle to crank. The faster you rev the more oil is doing this, the more power you lose.

Almost the same concept of knifedging a crank. As you are making the crank more aero drynamick so it can slice threw the soup of air and oil more easy. You end up with less frontal resistance.

How stupid is it to remove this on a DET with a stock T28 on it?

i build simple 300+ turbo motors in my motors i remove the girdles and i use 4ctw cranks

the last motor i put together using a roller rocker bottom end i made 280whp at 8psi of boost spiking to 12 on a greddy 18g turbo with LOTS of room to go in tuning as well as with better exhaust piping ect

i do not baby any of my engine i abuse them as much as i can and i ride the limiter alot when i race i have had very little problems with the bottom end, i tear my motors apart at the end of the year to replace bearings ect
