True, I don't think anyone is punting a T67 on the stock manifold. The comp housing is too large from what I know.
I have to say though the result from Kurtis is really nice. Spool is mega and so is power, but it needs to be said hes on a high mount and E85. The T67 is probably better off at the level Ron is at (with a cheap highmount) but the 5558 would be better in terms of contingency.
Not to rub anything in to anyone, but we all did say 'buy a hypergear' about a million times lol.
