It's crazy how much further the 2.0s are.Yeah, I'll share the dyno. Not a problem at all! It made 515WHP/444WTQ SAE on E30 @ 10 PSI. Dynapack hub dyno. Blue line was the winning run at 10.2 PSI, red was our "tried and true" baseline around 8 pounds.
My car is currently the stock block WR holder for the V6 version of the Genesis Coupe. Stock power is around 340 crank, 280 wheel.
The car is GDI and maxed out on fuel, and there are presently no options for supplemental port injection.But it's 11.5:1 CR with 3.8L displacement and was gaining about 25-30WHP per pound of boost as we got the turbo into its efficiency range. Was a fun day and we learned a lot about the motor. I wish we could've gone harder, but I'm at the theoretical limit of the block and valve train and definitely at the fuel limit. I'd like to come back again in a year or two with a built motor and a custom PI setup.
Let me know if this picture is readable. It's the one I could find quickly on my phone, but I have more kicking around when I get to a computer.
People have tried other turbos on this car: PT6266, On3 Performance 70mm CBB, various Garret GTX, but this Remnant Performance turbo beat the #2 record by ~50WHP and spooled several hundred RPM sooner. That makes sense, though, since the RP 70mm (and all Omega) uses the ODM design that also underpins the Garret G series, which we're all familiar with. Quick spool, efficient, good power.
I recognize this is not a lot of power by Supra standards, but it's groundbreaking for the Genesis community. There's a small group of us still hammering away on the platform and trying to find its limits, and there's been a radical amount of innovation for it in the last ~2 years. The ECU is goofy, we don't have good definition files, there's no port injection and, until Remnant Performance came along, the tuning was absolutely dreadful. So were the turbo kits and options. Remnant Performance single-handedly transformed the scene for my Genesis and ushered in an entirely new era of performance and power. Cars that used to explode on less than 5 PSI are now doing double that with performance levels that would be unimaginable pre-COVID.
I'm such a diehard for Remnant Performance because they radically altered how much it cost to go turbo, and what kind of power you could expect. I would go so far as to say they rescued the platform from total obscurity and triggered a whole new wave of R&D that's very exciting. Many of the mods we see on Supra are coming to Genesis now, a full 6 years after the last model rolled off the line. Just some context to help folks understand what's going on with another car, and why I'm so excited about them putting together stuff for the Supra. They proved themselves to me already.
Test conditions: 91°F, 70% humidity, 900ft elevation, ~3500ft DA.
Who tuned the 3.8? Nolman?
