Well I finally got my old junk on the dyno and tuned by Jeremy Formato. It's my old ls6 that was rebuilt. It has gmpp cnc 243 heads, darthv8'r old llsr cam and a ported msd intake. It made 544whp/446wtq running out of fuel pump in sheetz 93.
Idk....I think there's another 20-30 left in it. It was running out of fuel pressure so it may pick up a little there along with a few other things I'm gonna do. I think 570-580 whp might be doable.
My bet would be the old bolt on ls6 had a 10.4 in it there at the end. This thing should probably go into the 9s. Well see eventually. Right now i just want to enjoy driving some of which I have to be safe and short shift it till I get a pump in it.
I absolutely love the newer style walbro turbine pumps. I have three Walbro 450's in my rx7, the 267 part number pumps. They can make tons of power NA even on E85. I think one pump for E85 can make 750-800hp NA. I have one as a lift pump and two in an in tank surge tank system for my car - I plan to use an output on my Holley to turn on the second pump at high E85 %'s and also to trigger in case it sees a drop in fuel pressure.
They're so quiet you almost can't hear them turn on. Even if you don't need the fuel flow, the pumps are worth it for how quiet they are.
The E85 stuff is really coming around. However, Its different grades of E85. My buddie that drag races in the dirt have a deal to test the QUALITY of the fuel.
