I am towing the 10k+ trailer from SoCal to Yosemite tom. I am currently running TNT Sw-9/TQ-2/Time-2/RP-2/WG-off. Are these good towing options? I will go down to level 5 or 7. I am a big EGT wussy when towing. I will not keep it over 1250 for extended period of time.

Thanx.

Opinions?

 

uh, i towed my 10k trailer with tnt, but i was on level 3, tqman 2 timing 3, rail 1, boost off. my egt's never went over 1100*, but my turbos are different than yours.

i think level 7 would be too high, and definately 9...

 

The REVO is an amazing towing tune, but I don't like driving around with it. Regular REVO makes my turbo feel too big. REVO/TNT, with my current options, gets rid of any noticeable turbo lag. I will be driving the truck around for a week, I want it to run like I like it.

Maybe I will try what I have with level 7.

 

I tried towing my 16,000 lb toyhauler with TNT on 7. Took it out for a test drive and decided after the first hill to drop it to 5. Decided after the next try to drop it to 3. Worked fine on 3 with TM 1, Timing 0, RP 2. I have a g-56 w/ 3.73's and a sprung hub SBC 3250 DD 12 CB.

The problem wasn't heat, just some unnerving sounds from the area of the clutch and transmission coming up through the floorboards. I think the higher settings just strain the tranny a bit when you start pulling at about 1900 rpms in OD and if I'd have wanted to downshift on every little grade I'd have bought a Ford. I didn't really notice #3 being that much weaker than the higher numbers at lower rpms, where I like to run the engine while towing. It did seem a little gentler on the drive train while on cruise control though.

1900 for me is about 65 mph in OD (I'm running 34.5" diameter 19.5's) and it pulls like a locomotive there but the pressure spikes were too much for the drivetrain IMHO on the higher numbers. I love the way it runs and I want it to run like that for a long time and just figured discretion was the better part of valor.

With your lighter trailer you may not experience what I noticed with mine, but that was my experience grossing 23,500 or so.

 

jmcart: Just wondering how your towing with TNT went.

 

Just got back. It worked great on level 5. Only thing that stank was on my way home, before going up the Grapevine (Southbound), the gasket between the turbo & the manifold totally blew out. Not good for boost! Temps were not as good as the regular REVO, but going over 60 under 1100 degrees is not worries when hot out.


It was a bad time to go to Yosemite, it was totally smoked out from fires.

 

Just for a point of reference...

I towed our 10K camper (2007 Cougar) to VA Beach last week from central NC. On the way there, I averaged 13MPG running Smarty on lvl-5 with TM2 and RP2. However, I found it to be very laggy on slower roads (45-55) and tended to drive with OD off just to keep from lugging the motor. On the way home, I kicked it up to lvl-7 with TM4 and RP2 and had a much better time towing. The turbo kicked up quicker and I was able to enjoy the ride even the slower roads. The only drawback was my mileage dropped to 11mpg. But, I really enjoyed on TM4 - the power was always available very quickly.

 

Mine just blew out on my trip to AZ, had to drive 300 miles with that leak. I went back to the factory style gasket. I towed a 22' boat back with Lvl 3 tq2 timing3, Fp2 and got a big 10 mpg. Not very impressed with the turbo. The boat was covered with soot. Stocker in a twin in the near future.

 

Were you using the graphite type gasket? I was told by Dave at HTT that these were working out well...

Turning up the TQ might be a good idea for low end. HTT is sending me a metal gasket for free. It is coming UPS, so I might hit the dealer for a stocker so I can be on the road.

 

What sort of unnerving sounds?

 

Yep - that is what I did and got much better low-end performance (and little to no smoke).

 

ShutUpAndHoldOn asked: "What sort of unnerving sounds?"

It just sounded like it didn't like the torque. The sound was a lot like a ball or roller bearing in a loose race. Kind of a cross between that and coil springs being compressed and released. I even contacted SouthBend clutch and asked them if it was possible that since I had a sprung hub clutch, if that was possibly what it was -- the clutch springs being compressed. They just said it was the "...transmission saying give."

In any case, since I was towing pretty heavy and turning the Smarty Revo TNT down from 7 to 3 made the noises stop (and the truck still pulled like a champ, not quite as strong as the higher setting but still better than anyone has a right to expect from a 359 cubic inch engine --- pulled Wabuska Grade on hwy 95-A in NV at 65 in OD grossing close to 23,000 lbs w/ no excessive heat anywhere) I just liked it better. Have to give the SB DD 3250 its due: No slipping at all.

 

Oh. Just to add to the above, that was with 3.73 gears and 34.5" tires. I was pretty impressed.

 

Just got my smarty and fixing to tow the 39' Toyhauler. Trying to get the lingo down, you guys are still speaking spanish to me, all i know are the pre-programmed settings on the Smarty. How can I learn more?

Thanks,
