garrett to4e 1.15a/r expectations???
I bought this to4e 57 trim with a 1.15 exhaust a/r and p trim turbine. I haven't installed it yet but was wondering if it would be a good setup for street use. Should I expect heavy lag due to the 1.15 a/r and relatively small turbo???

The compressor will be a good match. Close to 400WHP capability, or around there, with a usable power band.
Do you have size specs on the turbine? The A/R is you have is rotary-friendly. Single or divided?

the ar 1.0 gave me full boost (16psi)at 3200rpm with a even bigger comp wheel then the t04e (i had a t04s 60-1).
this was a stock block s4 engine....with a rew and/or a ported engine the 1.15 will be better i think especially if you have. large port

For comparison, I was also running a to4s, with a 1.0, stock port 13B, divided manifold, dual wastegate setup, and hit 9psi by 3200rpm on wastegate spring (no boost controller to assist spool up)
With a 1.15, I wouldn't expect full boost by 3200rpms. Hope it works out for you tho.
