No the GT28 is efficient far beyond 14 PSI. The reason we use an extended tip, 7 blade, billet wheel, is it can extend the efficiency of the turbo. You can run these turbos up to 25PSI effectively.
Keep in mind the GTR is essentially 2, 3 cylinder motors. This car will easily run 9sec 1/4 mile passes with the right fuel and higher boost levels.
I personally feel these turbos work very well at 22 -23 PSI with supporting mods.
We will keep the community updated with this car and the Z projects we have going very soon.
Thanks for all of the support!
