Default Gen 2 LTX Turbo Dyno
Took my car to finalize WOT stuff as trying to do it on the street was just too much sketch for me.

383ci forged bottom end, 9.5scr, decent flowing heads, new hotside, and an old PT76gts turbo, 4in downpipe all the way out back.

Left it at 19*/16psi for now, basically where it was back when I ran HPT on it. I attached a quick screenshot, but its hard to read... backpressure was 26psi on the 15psi run. IAT were better than I expected so didn't feel like I needed to plumb in the water/meth setup I had brought.

Does anyone know a good way to convert fuel flow to a rough power estimate?

Upside to a big motor and tiny turbo combo. Just on/off power wise.

That DOOM Eternal intro though lol.
My 7875 LS1 was like that, made 674 ft. lbs. at like 4,000 rpm, it would just annihilate tires lol.

Randomly ran across the video on YouTube the other day and was like, "I recognize that car from LS1TECH!"
Congrats on the work and numbers. Looks like a real clean car too👍

Thanks!

Prior to adding a **** ton of stainless to the car, it trapped 140 so hoping to at least do that again before thinking what turbo I can upgrade too
