First tow with EZ and 275's

[John Berger]

Pulling a 6% grade on I-26: length - 2 to 3 miles ??



Temperature - 91 degrees

Boost - 26 psi (steady)

EGT - 1050





Pulling a 6% (maybe 7) in Tennessee on 19/23 East

length - between 3. 5 and 5 miles



Temperature - 70 degrees

Boost - 25 psi (steady)

EGT - 935



On the I-26 grade I never had to come out of 5th gear as the RPM never dropped below 2000 (came real close, though)



Fuel mileage on a hot day running anywhere from 64-68 mph averaged out to 10. 1 mpg. On the way home, I managed 10. 2 mpg on the first tankful (cooler weather, more hills) and on the last tankful I averaged 9. 9 mpg (hotter weather, not many hills, faster speeds 70-72 mph).



I'm very happy with the mods as they did what I had hoped. There is a wicked twist and turn 9% grade on the 19/23 bypass in North Carolina that I really wanted to have a go at, but my clutch was acting up (see the slave cylinder post) so I ran the grade in 4th and maintained 50 mph without any problems and with plenty of pedal left. The highest EGT I saw on the whole trip was 1050. The truck ran between 600-650 most of the time.

John, is your probe on the egt pre or post turbo???

John -



What kind of load were you towing?





Barry -



I'd say it is pre-turbo, given the EGT's he reported.

The probe is pre-turbo and the load is a 31 ft Nomad travel trailer. The weight on this trip was probably between 8. 5-9K.

That info looks great. I was looking at installing the exact same Mod's, and have the exact set up with my truck. have you dyno tested your truck yet??

No, but I have a GTech that I want to put through the motions. I messed around with it a little bit and I saw a reading of 266 but that wasn't redlining it through 5th gear. I want to do that when I know I'm not going to get stopped. I don't think the police would cut me any slack because I was testing mods

I should have mentioned that I ran my truck on a Dyno this past weekend. Results are 217 HP and 425 torque. 100% stock.
