I have a 2013 mustang with an on3 tt kit. I am running there 67mm billet wheel bb turbos. (.81 ar, 65mm wheel)

I have been 9.2s @ 150 +

while tuning the car my tuner says these turbo are really putting out a lot of heat and are out of there efficiency range.

I would like to make more power and have power come in sooner.


any suggestions on turbos to use ?

on3 brand.

Put some precision 6766s in there enough turbo for 1800 hp or twin 6266 enough turbo for 1500 hp. If you have plenty of room out the borg warner s366 in there.

not much room.

Turbonetics 6965's would be a drop in i think....
