Two weeks ago I installed the GTP38R on the truck in my sig.
I have driven this truck for 8 years, and anymore is mainly used only for hauling my trailer and pulling tractor. I have upgraded along the way as needed. 3 weeks ago my turbo started to go out at 180,000 miles.
Install was pretty easy, I deleted the Exhaust Backpressure Valve & Intake Air Heater, did the Zoodad mod, all new CAC
hoses and put a piece of 4 inch pipe between the turbo intake boot and the air box to delete the factory plastic connection (where the CCV
Initial test drive on the street I mainly noticed the noise of the turbo and pretty smooth boost build, right up to 32 psi
. Nice but nothing really special.
Last weekend I hooked onto the trailer with two tractors, grossing a tad over 25,000 lbs. This is where it got my attention. First I noticed better accelleration under load with EGT's staying under 1150F (pyro in manifold) and zero surge. I got it out on the highway and set the cruise at 73 mph, EGT's stayed under 1000F, and it ran so much happier. The engine ran like it wasn't working near as hard as with the stock turbo. I ran it up to 85 mph and EGT's closed in on 1200F. Driving 2 lain black top roads in over-drive I could pull 5-6% hills at 62 mph and keep EGT's under 1200F.
The difference in turbo's is like switching my chip from stock to the race setting. This is a well recommended upgrade with impressive results. I would never think that a turbo could make this much of a difference.
