if i'm reading this correctly the test car has the stage 4 setup? just curious since it's only made just under 500whp so far with 7.5psi i'm interested in seeing how much they gain with higher boost. other stage 2's have made 550WHP at 9-12psi so if this is stage 4 im waiting to see the end results.

This is not a stage 4 setup. It was late on Sunday night when I wrote what the "stages" were going to be. It had been a long week and I may of jumped the gun with what I wrote. Massive sleep deprivation tends to do that! :tiphat: We still have not fully nailed down what stage each turbo configuration will be.
The original stages of what I wrote were what we were looking at on paper. As you we all know, real world testing can yield completely different results. That being said, we see no need to offer previous listed turbine wheel options in the GTX28 series turbo's. When we define stages for our products, it is going to be related to vehicles requirements to be efficient. For example:
Stage 1 requirements are going to be for the stock car. GT2860RS, require mild fuel modifications, boost controller optional, pump gas tune for the individual that is looking to make between 450-475 RWH "daily drivable." This stage will also be the most affordable because for someone who only wants to achieve this power level, there is no need to spend unnecessary money on more expensive turbo's that they will never utilize. Everything for stage 1 will be supplied with the kit.
Stage 2 may require additional fueling modifications, i.e. Aeromotive pump vs. the Walbro pump to be able to fully utilize the GTX 28 series. As well as exhaust system requirements and MT clutch or automatic transmission modifications. A boost controller will be needed to turn up to boost for those who want to push the limits of what the stock engine can handle. The GTX2867R will most likely be our stage 2.
Stage 3 is for the big boys/gals! For individuals who want to make serious numbers. All of the requirements from stage 2 with the addition of internal engine modification, larger fueling (return fuel system), rear differential work and our 3" exhaust. Turbo's associated with this stage will be custom matched to your specific requirements, i.e. weather you are a drag racer, road racer or just the weekend street warrior. Our exhaust manifolds can support turbo's deep into the GT30 series. We can utilize turbo's that can make well over 1,000 HP to the ground if your drivetrain can support it.
The lines between the the 3 stages do not need to be in black and white. For instance, you can add a boost controller to stage 1 as well as take our car for example. This is a between a stage 1.5 and stage 2. Currently we are using stage 2 turbo's, no boost controller, still on pump 91 octane, low boost levels and the 2.5" exhaust.
All in all it depends on you as the consumer and what you want out of it. Very much like our exhaust systems we have designed a kit that can be custom tailored to your wants and needs.
We are still doing extensive testing with various combinations and the turbo system altogether. Our goal is to be able to answer any question thrown at us.
I think that this covers it all for now.
Thanks, Tony
