This will end up being summarized with dyno results, but only the results from the GTX turbo will be posted, due to the fact that I havent ran my GT3076R before doing this upgrade. However, I could post the results in comparison to my older setup using a GT3071R.
I visited ADP distributors in langley, and discussed upgrading my GT to a GTX, and they offered to find me a wheel. I ended up chatting with them later in the week and they had found me a billet GTX wheel from one of their suppliers. I was able to get the wheel for $200.
This upgrade has well documented results already, and there is NOTHING but good things to be said about the upraded billet wheel.
It provides a higher pressure ratio it doesnt fall on its face as hard as a standard GT30. Infact, there were tests done with the GT3076r in comparison to another GT30 with an upgraded billet wheel ( similar design to GT series wheel, but not GTX style) And both the standard GT30 and hybrid GT30 actually out performed its larger arch rival, the Precision 6262. The previous billet wheels showed gains over the standard wheel, however they arent as impressive as the new GTX wheel. Looking at the maps, it appears every GTX turbo excels over its previous GT series. The GTX3076R is basically a replacement for the GT3582R. Its that efficient!
I bought a GTX compressor cover and decided to compare their contour and see where the blade has its differences. Ill be getting the blade later this week and giving ADP my turbo, to swap in the new wheel and balance the assembly.
With that being said, ive only been able to compare my compressor covers, but just by setting the GTX cover on my GT3076R, you can see how the blade will be slightly larger. The blade has lots of room around it when the GTX cover is placed over it, and the contour of the blade will be different with the GTX wheel aswell. This space may change a bit if the GTX cover requires any profiling to fit the wheel. Ill post any changes that may be made. The service at ADP distributors is awesome and I should end up with a killer turbo.
Ill be sure to post up pictures once the swap is done. And sum everything up with some dyno results.
