I finally towed with my new turbo (& cam). EGT's were so nice. Trailer was over 10k. I was on regular REVO, all default, level 7. From Bishop, CA, to Mammoth lakes, CA (Sherwin Grade it is called), I kept it in 5th gear, EGT's stayed at about 1100 to 1200. They actually stayed cooler in cruise. It was 94 degrees at the bottom of the grade and 84 degrees at the top of the grade. Staying at 60 mph was no problem.


I do notice less boost & more smoke.

By the way, Bishop is like 4000ft and Mammoth is like 8000 ft.

What are your temps at 85 mph? ;-)

Hows spoolup at those elevations?

I'm at similar elevations(around 5k most of the time, going up to 7500 on occasion).

I was thinking a HTT 62/65/13 would be about right for these kind of elevations.

I have the 62/65/13ss. it seems to do really well. I am still tuning but spool is not bad. I can still get very hot so I am looking into water to help with that problem. With the injectors and some of the smarty programs it will still lay down a traffic stopping cloud.

I might hit 85 on the way down, since I do not have an exhaust brake. Spool up is too slow up here. With the trailer it is not that bad, as soon as you get a tad of boost, you can mash the throttle and boost hits, smoke is not that bad (once boost hits). W/o the trailer, I would rather a 62/65/13.

If I lived up here, I think I would have to bone up for twins.

I've towed 15k lbs at speeds forbidden to talk of on these forums with my HTT, and after a certain speed it just levels out to 1150*. For me, it tows great, the Mp-8 really gave it some more attitude. I'm very satisfied with its performance. That said, i don't tow excessive weighted loads much, maybe once every 2-3 months. My frequent loads average 10k. In most cases though the 65 wheel will be more effective at towing, especially with my fueling mods and pressure.

"15k lbs at speeds forbidden to talk of on these forums"

LOL...I love it! Spit coffe on my computer...the speed police always bust my tow/haul stories.

My worst violation was the 1000 miles trip non stop at 80ish, 1400 egt, grossing 27-30k. The A5k survived that!

My 62/65/13 stays nice and cool pulling our 10k backhoe. Tnt revo on 9 with tst on 2/2, it maxs at 800 degrees post turbo. Really wished they'd installed it pre-turbo. And if anyone has been in central MO, then they know its not flat around here. Just $0.02
