Title says it all :)

Thanks a million to the @Fullblown, 2J-Racing and the awesome team at Syvecs. The car wouldn't be where it is without your help to get me back up and running. Car pulls like a freight train. Max boost is set at 1.7 bar or just under 25psi on E75.

...is E75 a typo?

Now that you have a more appropriately sized turbo, what do you feel is limiting the 2.3 with respect to power on the high end? I ask because you're still (roughly) maintaining peak power when you stopped the run at the stock fuel cut. I had personally expected it to be the stock turbo and valvesprings and that those with a larger turbo and supporting mods would see a benefit in raising the redline.

75% ethanol is what was measured in the tank. So while the car had "E85" in it, it was really E75. The redline can be raised but I see no reason to do that at this point. 515 is plenty. @Fullblown made almost 600whp with this very setup with exception of the cams.

Nice. That torque curve is much better than I was expecting. Looks like the torque still comes on low enough to be fun when you arent kicking the gas hard.

Short version: The ****ty headifold. The head just isn't made to flow a ton of air from the factory, and there isn't a lot of work you can do to easily to get them to. Which is why cams don't do a ton for the RS. Need to open up and smooth out the exhaust passages, but there's not much space/materiel to do so.

Congrats @bludrgn happy to see the results it's been a journey.


Off topic side note LJ said that my Aux Rail should ship today so I hope to be roughly where you are by next weekend.
Awesome man. Looking forward to seeing what your car does.

So based on prior posts, your non-answer=self-tuned? If that's the case don't be ashamed of it, if the engine holds together that's a nice curve.

So... will it ever see the 1/4? Great numbers for sure! But it's one thing to put them down on a dyno and but them down a track.

Was the Mountune Intake Manifold with injectors ever under consideration? Reasons? Just curious.

Congrats on nearly being done. Looking forward to your impressions.
