just trying to see if anyone who runs a 60 trim with a .64 ar has any feedback to give me :)

basically im debating if i should buy another .49 rear or buy a .64 housing for my t28 non roller bearing turbo .

I have room in my life for a little more lag but dont fancy waiting till 6k for 20 psi lmao. I have room high up for peak power to be made later too as its only made at 6-6200k so thats ok. Car is used on the road but i did build it mainly for track . msm cam so plenty of lift and what not .

Any help much appreciated as normal

When you say track, do you mean drag or trackdays ?
I think Rob @ Backyard (Rob@Backyard) used a GT28r at some point on the drag strip, pretty sure a couple of other people tried it as well.

The turbo I run has a .64 ar but is smaller than a 60 trim, I get full boost at just over 4k/4.5k depending on how much and I have a piper 285 cam, so with a 60 trim I should imagine you will get boost quite a bit later than 4k. the .49 ar is really the ideal option :)
