Looking at upgrading to a 90mm looking for opinions on what improvements it provided. Will it increase MPG?
TooCool, sounds like you got excellent results. I didn't have a A/F gauge at the time and unfortunately the new TB85 didn't really feel any different from stock. I have the old TB taken apart from experimenting with it and will have to put it back together and test it. Thanks,Originally posted by TooCool:
Oh i'm not comparing my dremeling to his with the proper machinery. But that one is only opened to the throttle blade like mine. For what you get out of a ported TB, i fiqured i use the money for other mod's and do it my self. Think i got the result's i was after being my wot 12.5 afr went to 13.2 afterward. I also opened up the back side to match the intake and polished it while i was at it. It wasn't hard to do and had fun doing it.
