A little fire out the exhaust, but not terrible. Timing advanced a couple of degrees might cure that. A little more water and/or fuel might cure that. Don't know enough about the build to say any more. 10% slower gear would have helped on that pass, as the engine didn't stay up at the end.

What size is your cross over tube, do you have a velocity stack in front of your turbo?? Any methanol in your water?

Nice pull !

That is a damn nice pull, only a 301!!! A 3inch pipe will flow twice as much air, I use a 3 1/2 .

Did you banjo the cross over so water mixes in better?

O.P.S. Heads, the 12 gph is my water injection. Im running frozen boost cooler with 800gph ice water. Im also doing some ice water cooling in my intake (another 800 gph) thats a long story to describe, lol but helps quite abit.

Thanks nevergreen. not sure what you mean on banjo crossover. Would like to hear more.

I also was mistaken. My boost pipe is 3"

I dont know if you have room under your hood but a banjo is when you 90 the cross over towards the radiator then 180 it back, then down to intake, more pipe mixes the water better, thats also why I use 3 1/2 for all those elbows.

Worth up to 40 HP on the dyno according to my turbo maker.

Ive seen one engine the pipe went up front then down between engine and radiator then all the way along bottom of engine to the back, up again then towards front then down to intake.

Ive been thinking, with your intercooler that might atomize the water good enough???? Too bad its so damn hard and expensive to dyno these things.

Rules dont allow you to spike the drink???

I don’t think The longer piping route is not at all that important when you have an intercooler. It does help when you don’t have a cooler. As long as you have big enough pumps to keep the cores full and enough water shortest is better between cooler and manifold.
