We sponsored Mark Jacobsons manifold. And as for the Supra manifolds, well that depends on who you ask..... Of course, you would be silly to ask the opinion of someone representing the opposition
If you are that interested in the Supra manifolds, why don't you ask GAS? They aren't having any probs making over 1000hp.
Oh, and BTW, D-Sport made 100hp more ATW (850 to 950) with our manifold compared to a Trust with 47mm butterflys.
I could be wrong, but i'm sensing a little negativity from you. Any reason for that?
