GTX2860 @ 20psi Dyno
I just got back from a dyno day at a local shop. Pulls were done a Mustang Dyno that's pretty notorious for hurting feelings. I held the "lowest HP" award for a few hours before a 2012 Camaro SS took my crown with a 312whp pull. For what it's worth the printout shows an estimated Dynojet number of 368whp, which made me feel a little better.
329whp, 281wtq @ 245kpa
300whp, 250wtq @ 210kpa
329whp, 281wtq @ 245kpa
300whp, 250wtq @ 210kpa

2000SE
Stock Motor with Eagle rods
Stock drivetrain 6sp/3.90
BEGI cast manifold
Gutted intake manifold
2.5" intake piping & Fab9 350hp intercooler
Artech downpipe
MKturbo exhaust
Toyota COPs
ID1000 injectors, return fuel system, DW300 pump on E85
I made a couple shakedown pulls this morning before the dyno that show spool. 16psi at 4000rpms, 20psi at 4300rpms, now that I look at it that seems a bit weak, but I dunno. These are the same pulls on virtual dyno's dynojet and mustang dyno settings.

Nice result - and pretty timely for me as I'm about to get mine mapped with a similar setup (but with VVT and a tubular manifold) and am hoping for similar ballpark numbers...
What kind of duty cycles are you seeing at full chat? I've only got 620's but we don't have E85 in these parts, not sure if they are going to be a limiting factor or not...

My log showed duty cycles peaking at 75.1%. That's with a pressure referenced return fuel system and I think it's at 75psi base pressure.

I'll probably run out of fuel before my goal. I only plan on making 400+ on the dyno to prove the setup can make it and then turn it down to 350 max. But with pump gas I dont think ill make it there. I have a ported head, back cut and tapered valves, 84mm ST pistons, etc. I should know in about a month.
