True North Turbos TNT366 66MM T4

Awesome turbo!

I've got this S366 68mm turbine T4 .88 a/r on an 01 VP44 Cummins, its a little laggy as I would expect on a VP44 pump but it really rips once it spools. EGT control is very good as well. I have 300hp injectors, Fass, Edge tuner stacked with a Diablo power pup and upgraded valve train. The turbo would be too big for stock fuel as its laggy even now, but over all a great turbo!!

Fantastic product. Customer service is matched to the product

Quick spool

Put on a 4.6 2V , this turbo is huge compared to the PW T66 unit I had on before. But going from major back pressure issues at 10psi and spooling at 3500rpmbut falling off at 5500, this turbo is spooled up by 4000rpm and ready to haul the mail at 15psi all the way up to 7000rpm. If you're looking for a mild V8 build (450-600ish) I think this is a great option especially compared to the Borgs or Precision turbos which are 3x the price
