Impressive setup...

Will you offer a slightly smaller turbo that can come in a bit sooner, like 3500-4k range?

Doesn't look like it was in shoot out mode did you baseline on that dyno? Nice looking kit.

Yes, they did. Please search through the thread and you'll find their baseline. You'll also find a comparison against the vortech supercharger. Finally, you'll find their turbo before wmi and lower boost before being raised.

We haven't run into any kind of compressor surge at any boost level so far. However, we're also running the standard GT3076R compressor housing with the 4" inlet and anti-surge housing.

We have a customer that is looking to run a GTX2876R, so we'll have a dyno chart for that set-up in the near future.

With the current GT3076R putting out 185-195+ WTQ in the 3,500-4000rpm, the car has no problem accelerating in that part of the powerband without downshifting.

Haha they used my old Genesis Coupe (*cough cough* 500whp *cough*). I can't wait to get my FR-S and build it up. Looks like the PTuning crew will have to put up with me for another go. Haha

Thanks.

Shoot out mode calls for a ramp rate that is just too slow for dyno tuning. It would basically would make a fifth gear pull very very drawn out. It would be great for a turbo kit shootout day, but not so much for doing a couple hundred dyno pulls on a shop car.

We dynoed stock FR-S' and BRZ's using the same ramp rate and 5th gear and they baseline at around 159-161 whp. We use 160whp as our baseline.

Ah right. Do you have a boost plot for the above graph? Thanks

Maybe I might end up being a customer running a gtx35

Is pricing come out real soon ?

WolfsFang · 05-21-2013, 02:14 PM

can you give us a idea on how much labor would be if you offer to install these in your shop?

So peak boost is at 5k rpm? Was that interpreted from the dyno graph? Just trying to learn some things, thanks!

Very interested in the GT28X, I don't want the massive power spike the GT30 has. I only need about 280-300whp but I like the WMI idea.
