[QUOTE=RER_Solutions,Feb 9 2011, 07:52 PM]Sorry, I am not impressed.

 

A few members have inquired about running a smaller turbo with our turbo system. They want the best low end torque and response. It may come as a surprise to some, but our set-up with the standard GT3076R and standard Tial .82AR turbine housing has no problem hanging with the smaller turbo set-ups when it comes to low end response, spool-up, and torque.

Below we have three turbo set-ups. We've selected all AP2 set-ups to make the comparison fair in terms of the torque and boost curve. The Greddy and Godspeed dyno charts were chosen because they're both running small turbos that offer very quick spool-up and low-end grunt.

The three turbo systems are obviously running different boost levels, but regardless, you can see that we make more torque right off the bat (pre-spool). The boost curves are also very similar, even given the fact that we are running a much larger turbo.

Power and Torque:



Boost:



The dyno graph for our PTUNING Turbo System explains why (at least with the 2.2L AP2) you can literally drive around in sixth gear at 2500rpms and the car will not buck or complain when you start rolling on the throttle.

Also, we've had many customers inquire about the differences between the GT30R vs GTX30R. The GTX30R will outflow the GT30R on the top end or at higher boost levels, no question. However, it is not a 100 percent win win situation. The GT turbo does spool-up slightly faster than the GTX and therefore also makes a bit more low end torque. If you're looking to eventually run a built motor, WMI, E85, or race gas, then the extra cost of the GTX will be worth it.

WOW! very glad to see the 30r out does the greddy kit!
Ptuning keeps blowing me away at how well this kit performs! Still need to install my kit :-(

 

Excellent comparison of the 3 turbo set ups. Interesting to see the different spool/hp numbers by rpm of each kit. More fun to drive my PTuning s2k.

 

I can't wait to see the dyno numbers for your set-up!

 

Jason, I'm glad you're enjoying your set-up. BTW, you probably know that's your dyno chart. :-)

 

Any ideas what the gtx3076r will flow with a .82 AR? like maybe 24 psi? wasn't the gt out of breath at around 22?

 

We actually use .82 AR turbine housings in all of our turbo systems. You can certainly try to experiment with a 1.06 housing to see how much more top end you can get. We have not yet done a race gas tune with the GT3076R, but I'm sure we will eventually.

Unfortunately, we stopped the race gas tune on the GTX3076R at 22.5 psi due to time constraints. I'd say 550+whp on our DD Dyno would definitely have been possible if we had more time. However, from my experience, at 530+whp on our dyno, we most likely would have needed to address having only a single in-tank walbro pump.

I for one see the enormous potential of ur kit and those turbos. Ur dyno reads low and the numbers are phenomenal. Please test this kit on a car with an aeromotive pump!!!!!!!
