once you get that 60ft knocked down you'll be knockin on the single digits! How much boost are you able to build on the footbrake?

3-4 psi max on the foot brake. this converter is tight since it was built for nitrous.

How well are the 80s keeping up with e85? And at what fuel pressure?

Actually my fuel pressure under boost is 62-64psi.
My idc is at 100%, but I need another regulator so I can crank up the fuel pressure.

NICE. Gives us an idea of where we'd be with a lil more power and much more bite. We went 11.50 @ 128 with a 2.0 on a street tire(not dr) with a 10psi 550rwhp(gas) 6 speed goat in the hot fla summer. Hoping to run similar mph with this cool air. Kinda digging your fuel system setup too.

Tight work, very cool build.

That's what I was afraid of. Hopefully copious amounts of meth will make it work better for me
