Any flow numbers on fully race ported GN1's?


259 Intake at .500 lift from Todd Mckenzie.
These are not the Rs.
Todd does work for some of duttweiler's projects.
More work could have been done but these are
going on a 109 3.8.

[tweaked]

The best that we have had done is TWO[2] sets - "Black" now on Neal Whyte's "NASTY" and Mike Kurtz.

Both sets flowed over 300 @ .550 BUT ...... they were done by a friend for a friend. Probably could not afford to buy them.

Normally anything better than 260 is real good.

Have a nice day.
