I work a lot with dynos and that dyno chart is missing a lot of info. I never said mandrel was not better then chrush. I just said is it worth the money on some cars yes and some cars no. I know on my car I would put mandrel. But if I could get some thing better I would put that.
(Cobra Neck) flows even more then mandrel. The more you bent it the bigger the advantage. but I know the cost would be too much. Because nobody in the automobile industries offers it or even knows about it. Its been around for years on bikes.I just wanted to see if some one brought a new idea to the site what would happen.I can tell you my experience was not a good one. when people do not understand they just start insulting. The funnies thing is nobody ask what (Cobra Neck)is. It seems every body knows better.
