Could anybody tell me where this A/R will be best suited ( rpm wise ) ie what port

It is currently going on a bridge port but i am conceaned that it is too large and will not deliver at the engines peak rpm (8500 rpm)

1.22 on what size turbine? I'm going to assume you're talking about a P trim. If so then that is defineatly not too big..

 

The only info i have is its a matched gt42 r.

 

I would imagine that you'd be fine with that on a Bridge port. I don't think it is too large.

I had 1.30 AR open volute w/ P trim on my J bridge. 10psi @ ~3600rpm. I calculated it to hit at a higher RPM, but maybe it was due to pulse effects.

 

You will be fine with that housing

Common choice down here, its actually a bit small for the GT42R, two top untubbed cars (13B and 12A) world record holders actually run a 1.34 GT rear housing on that frame and need staged boost control in each gear as to not make too much boost pressure and over power the track in low gears

Both run about 30 to 34psi and trap 164mph range in road cars.

 

Fantastic stuff. Cheers
