A quick update after a couple days of commuting to work. I love this turbo, not only for the sound (which is sweet) but the performance is great. The burb seems to pick up speed with much less effort, especially at higher speeds it doesnt hit a speed wall like it used to. Apart from the turbo whistle the truck actually seems much quieter under cruising speeds, although ive been enjoying spooling this bad boy up.
So far I havent noticed a huge jump in power between my stock turbo and this one, but the overall performance and manner of the vehicle has greatly improved.
I have a 70 mile round trip to work and back, 90% highway. On my last couple commutes to work this is where the numbers sat on my sustained highway journey that is mostly flat with some mild grades (max boost is set at about 18PSI at WOT):
(these are the readings MY guages are giving me)
AVG Speed: 60MPH
RPM: 2000
Boost: 1-2PSI
EGT's: 400-500
Trans temp: 150
Coolant temp: 185
I have yet to test it loaded or under sustained high boost other than about a half mile highway run up a mild grade, 18PSI of boost with EGT's hitting between 8-900. I also plan on limiting the boost to 15PSI.
again this is just quick observation, i havent studied it to much as im really just having fun driving it right know. As soon as i calm down a bit i hope to get a little more accurate with all the readings and do some homework LOL.
