Pretty simple thread, just curious as to what single turbo you run, is it ball bearing or journal bearing, and what A/R do you use on the turbine side...also is it split flange or not. Then if you wouldn't mind commenting on spool and how the car pulls to redline.

surely that dont mean much as its just a wheel to housing size comparison?

A single .86 housing T28 gives a LOT less power than a .86 housing T72, lol...
well of course...but noone is going to run a single T28 on a gtr...thats why I also asked in my thread to state what turbo it is on.

I currently have a .63a/r single scroll GT3076R on an RB25DET running 1bar. Its made over 370whp so far and has 2psi by 2000rpm, 10psi by 3200rpm and 1bar around 3500rpm - with huge midrange pull. Its only running a .63a/r as I'm on stock internals and not intending on pushing the turbo overly hard just yet, so focussed more on getting it spinning a bit quicker in the mean time.

Its not "choking" within the 7000rpm redline at this stage.
