Would be nice to be vindicated, but can't take it from a conversion. Soon maybe.

yeah i remember that LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOONG engine tech thread.... i read it from time to time...

3sge beams was truly a bad ass motor

Good ole DynaPack. This plot looks like it was trying to show flywheel numbers instead of axle numbers. As usual, it would've been better to see raw data, but in the forum landscape of info vulturing, we'll take what we can get. Strangely, another example where the engine dies soon after 6k RPM.

-->carbonBLUE: what shop was this done at?

AVO Turboworld did the test

It was done in Japan at our shop in Akishima, Tokyo. It will read slightly higher there vs. most of the USA due to gas quality differences - high octane in Japan is considerably better than the piss water available throughout most of California, for instance.

The way the torque drops by more than 10% in 500rpm looks nothing short of hideous.

A while driving in, I've always check the RPM to check for feeling of torque lost in 3,000RPM~4,500RPM and I seriously couldn't feel the torque losted.

This isn't what one would call a high torque motor. If you were dropping from 400 ft/lbs to 360 ft/lbs, you'd feel it. On this motor, that's only a very minor blip when you are revving through, which is only going to be really seen by the dyno.

Fixed

I'm in very little doubt that I'll be able to feel that as plain as day.
