Boosted Performance single turbo build

The flat torque is nice, however for entertainment purposes it's at 411. With my Gtm TT kit on my graph the lowest point is around 411. But the highest point is 496. I'm still very happy with what I have.

Recirculating is standard, and no high flow cat options at the moment.

Got it, thank you. Yes you are the first to send in a deposit.

At peak power of 550whp, the boost was 9psi, not 12psi.

That is crazy talk....however


As mentioned before, torque is a function of timing. The more agressive the timing, the more torque the engine will put down. I can provide countless dyno graphs to support this.

I have noticed that GTM dyno charts are very aggressive early in the rpm range. You can tell that by the way the torque goes up out of the gates, again, early in the RPM range. A lot of tuners will avoid this on stock blocks because it is a lot of stress on the engine. If you look at the 550whp chart you can see that the boost is already at 10psi by 3750rpm, so if the timing was advanced the torque would have shot way up in the 400's. Then as the RPM's go up, the torque would taper off. Instead, a nice smooth, flat torque curve is simply easier on the engine, prolonging it's life.

EDIT:

Here is a perfect example of the same kit with a different tuner:

Note the torque curve between 3500 and 4500rpm...easing into it. I

I am not arguing your numbers at all, or the kit it performs great. Just noting how timing/tuner have a large role to play when it comes to presenting the final graph/numbers.
