On 93 he would have more then enough. But ya a bad pump can happen. As said if he went E85 he would have issues. Plnety people in the 700whp range with no return style on 93 with no issues. But also they still have stock compression so don't need as much boost as him since he will be 9.5:1 now. But we was already talking about him getting fuel system while doing the engine. That way he don't have to detune it or run less boost.
Terry was on E85 when he made 1000whp. And from what I was told by Lund I would need a fuel system now if I went E85 even for over 650.
Yes, and it is a smart idea to switch to a fuel system at 650 even on 93, just from the inherent flaws of a returnless fuel setup, the safety overheard on a return style is worth it imo.
