    Man someone's been on the sauce and or the wacky tabackie tonight big time. Lmao

    Any ways. Yes post turbo you are safe at 800-1000 sustained and ok for a few short bursts to 1150 or so but keep the time there very short and not very often.

    Now my 6.4L powerstroke can bury a 2000 degree pyro (pre turbo) when a camaro or the like needs a schoolin but thats only for when I dont have any F's left to give and Ive been trying to blow that thing up for years and it just wont die. Lmao.

    What kind of weight are y'all pulling that you're getting 1,000+ degrees post turbo?

    Why is the air hotter pre turbo vs post turbo, wouldn't the compression of the air make it significantly hotter?

    Thanks for the replies. Purchased used with no history. It has plenty of juice just wanted to be safe. I thought all S60's had steel top pistons and may have a higher temperture limit. I will get the numbers when it comes back in.

    ? The turbo doesn't compress the exhaust. The exhaust is what makes the turbo spin.

    Let's see. 110K to 134500 several times with seacans. I had license for Md and Va for 99K gross standing at all times. Strictly between either Baltimore or Norfolk for shipping. The 134500 gross was the amount recorded at the stephens city scales before it broke and dropped me a truck about a foot onto the steel beams below it. The ticket that day was 3000 dollars against company. I was told New Market in Md on 70 was open with a wink.

    Considering the terrain I crossed below Tuscarora Md on that 5 span bridge east of Harpers using US 15 and then US 340 to Md 26 the walkersville bridges were slated for demo in three weeks time so I selected those to cross the Monacacy. If they dropped with me on it oh well....

    This was back in 88 I believe with a mid 60's short mack offset cab. Maybe a 230 Detriot roughly. Wound out maxed. Maybe 8 mph on 3% grades top speed 28 before the entire front end would go out and run me off the road, load and all.

    The actual gross weight?: That's theoratical. Probably in the 155K range give or take 10. The tractor was totaled. Never saw that thing again. Did not hear about any crane problems lifting that heavy ####### onto the ship for Europe though so... It must have made it. God help them...
