Whats the inducer and exducer size on the 991 GT2 RS turbos? Is that them in the pic? How do the new GT2 RS VTG turbos compare say to 991.2 turbo s VTG inducer/exducer size?
Great project. Yes, that is them in the pics. The car went on the dyno today and got dialed in on 93/meth. Numbers on 93/meth, race gas/meth, 60-130 and 1/4 miles times are all to come. |
58mm compressor wheel on 991.2 turbo s. According to AP head of Porsche GT cars 67mm compressor wheel on 991 GT2 RS but everyone measures them differently. No-one so far has been able to tell us if the hot side on the VTGs is bigger than on the old 997 GT2 RS VTG turbos.

Ya so it does seem that the GT2RS turbos are much larger than the 991.2 turbos.

Yup, that’s what I want to know as well. While dyno numbers are cool, the question is how do these dyno numbers translate on to the street / track. I already got 60-130 numbers today on 93/meth. Very impressive! I promise to share it all soon! |
