200whp+ on 93 would be amazing. But, IDk I have reservations on how well it will perform on E85. Though the runners are larger and not hurting VE on pump gas, will the added length hurt VE and top end performance at higher rpms where the knock resistance of E85 becomes advantageous?
That said when I had a full exhaust and the Crawford BPBs that this forum is divided on the power band was much more lively and had better drivability than without them on 93, with an appropriate tune of course! Once they have this it will really showcase their manifold design.
If I hadn't already sent a MY17 manifold out for extrude honing, I'd commission Racer X for a similar design to what they came up with slightly shorter runner legs.
But I got curious.
