Dyno numbers are in on my build... Finally haha. Picking it up tmrw. 917rwhp on just under 19 lbs of boost. Twin 61mm turbos on E85. My pumps are maxed out at 20 lbs so Mayhem is saying there's easily a 4 digit dyno number there if we had more fuel. Currenly on twin Walbro 450 pumps. Ill post the dyno graph tmrw when I get it!!

I have twin Walbro 450lph pumps on e85 and making closer to 1200rwhp...... -10AN feed with -8AN return.

Let's say each pump flows a little over 300lph at 80psi.... so you have over 600lph with twin pumps..... that's enough for around 1200hp with 13.5Volts to the pumps!

Injectors are Racetronic 160s and we think the lines might be a size too small and not the pumps. Heres the dyno graph

Honestly I'm not sure how the fuel feed lines are done as LS1EXCITEMENT in Durham did them. As for the turbos... member FORCEFED recommended them to me (3 or 4 years ago) so I remember they are 61/62s and CXracing ceramic ball bearing but I can't find or remember any more info on them.

I made 1221/1176 through -6 feed and return on a TT (2 x 6565s) 427. It is about keeping pressure up and not line volume. I did have a boost a pump on the second pump. Are you logging fuel pressure?

Great numbers!

Glad those turbos are working out for ya. 850ish was the goal if I remember? I believe those are the small 61/62's. It's pretty much a .96ar T4 GT35. I'd think they would be about done at 900whp, but who knows!

The T3 GT35's were 100% tapped at 850ish whp on a buddies LS1. Guessing the larger T4 housings let thosego a little farther!
