Default Single turbo dyno 570 WHP (93 + meth) - 09-28-2013, 10:51 AM

Hey guys,

I finally got this project of mine onto the dyno. My current setup is a top-mount GT3582R w/ 1.03 A/R Tial housing and JB4 w/ Cobb. These runs were done on 93 + meth (80/20 with two CM7 nozzles). Boost peaks at ~22 psi. Transmission is 6AT. I'll post up a log tonight when I get home. Thanks to Terry for his support on this project! I was only hoping for 550 whp.

Looking forward to checking out the log. Is it possible to dial in say 26psi @ 5000rpm tapering to 22psi @ redline to flatten out the porer curve a bit?

There is probably some work that can be done on the boost curve. My settings aren't too creative lol. Pretty much a flat "curve" now.

The peak power is great but you want to bring up the power under the 5500-6700rpm curve.

Yeah, that power curve basically says "next stop, the moon" haha. Looks like an Evel Knievel ramp. Torque is ridiculously flat, though. Looks like my first girlfriend.

Since looking at Shiv's top heavy single turbo dynos I've always wondered if raising boost down low is simply not possible due to the hardware or if he is just too lazy to try it.

Octane would be my first concern. The hardware *should* allow it.

What RPM are you hitting 22psi with the big hot side housing?

I'll have to look at my logs again; but on the street I can hit an even 20psi right around 4k.

Terry, I'm not following your reasoning/logic as to why it would be advantageous to taper boost towards redline. The peak power RPM will be lower, thus flattening the top of the power curve, but in no way will this make the car faster since power is being reduced nor will it shift the curve itself in any way.

Just curious as to what I'm missing as you are the most knowledgeable on this.
