Update for me! Just picked her back up today after nearly 5 months at the tuner (winter storage he called it, lol). This was the hail mary pull at the ragged edge of the fuel system capabilities at 17 PSI. Fuel system coming along with 4 figure numbers one of these days when I get to it.
that's a really strange readout... if hp & torque are on the same vertical scale and overlayed across the same RPMs, shouldn't they cross at 5252?
and then the torque reading is much higher than the hp (atypical for a centri), and the numbers don't calculate to the estimate at the bottom.
or is it something to do with the correction method that i'm unfamiliar with? i'm so confused right now.
I was just looking at my graph......I really need to do my fuel system, that car flatlined just over 900. I think it could have gone closer to 950 looking at the curve if it hadn't been out of fuel.

you aren't on e85 either right?... I bet your car would crack 1k on e85, it was already flattening out just after 5500 and already past 900rw so with another 1500rpm plus e85 I don't think it will be a problem

Nope, 93 and meth right now. Need to build a fuel system and retune for that first and with a little more boost and proper fuel it should crack 1k on the 93. After I get that done I'll save up for the injectors and swap it to E85 down the road.
that makes more sense now.
and i forgot to say congrats the 1st time... hitting 4-digit power ain't no walk in the park!
Thanks. Engine should pull more high rpm. When was best power, boost was 1.35 bar, boost rise to 1.55 but its not make more power. Maybe stock ls3 intake manifold and Kooks 1 7/8 headers start to choke...

any reason you aren't just going straight to e85?... injectors to handle that kind of power on ethanol are expensive so if it's money I get that

Money is the thing. I can piece together a fuel system with the injectors I have now and lean on it some, and then just down the road when I can afford a $2K set of injectors, I can dump what's in it and swap it to E85.
@C5-Fan What that pull at 28ish lbs of boost judging by that cut off lower graph? I'd like to know a little more about your setup, it's impressive.
I built the car for Drag Week so it had to be dependable because it will take a beating. It was already making more power than I thought so we decided to make some test hits and see what the converter does before turning it up. Once I spin it to 7000RPM it should be well past 1200 RWHP
