[logan_450R]

Any one run a rev box in there 660 and what brand is it and how are the gains from it low? mid? high?

we have put them on about half a dozen 660s in my group... i reccomend them... we use the big gun one i beleive... i dont know as how you gain tons in perfomance as far as more HP, but what is nice is not hitting the rev limiter so easily... for instance if your rear end comes up through the whoops...
