Engine/Transmission (1998.5 - 2002) Anatomy of the DTT Stainless intake

[Allnew2Me]

Take it easy there Blair, not everyone hauls around their vacation cabin like you do. And some guys even go slower than you speedy fellars! Either that or when he says "fifth wheel" he is just referring to his spare tire!

17MPG towing a 5th wheel, man what kind of engine does that 5th wheel have and do you subtract the 5th wheel mileage from your truck mileage? Must be a typo or a very small 5th wheel.

Well, judge for yourself:

For sure, it's not the "Bulge-mobile" some herd down the road - total GCW loaded is about 14,000. I always got around 16. 5 MPG with the older '91 truck, and also on this one until recently - maybe the engine is loosening up a bit more, just under 60K miles on the truck. It helps to drive around 60 MPH as the speed laws out here specify (55 MPH, actually) - and the LACK of 4WD helps as well.



OH, and yes, MPG is hand calculated!

Well I guess it is not a typo so I am selling my 5er and getting one like yours. I guess it helps if you properly size your trailer to the truck, I must have missed that day at school.



Only problem I have now is I can't get 17mpg empty !!!!



Well done Gary.

Well done Gary.

Last several longer distance trips empty, we got a bit better than 22 MPG - cruising mostly at a bit over 60 MPH, with a few shorter distances over 70 MPH, such as Nevada and California, with higher speed limits than Oregon's 55 MPH.



For sure, I'm very happy with my RV/truck combo. While in some respects, the trailer may seem small vs the truck's capability, but with about 750 lbs of bed contents, fuel/tool box and 5er hitch, plus other RVing essentials, the 5er itself has a pin weight of about 1200 lbs with the 5er fully loaded, which puts me slightly over the truck's 1880 or so available additional GVWR for towing as we do. The setup tows beautifully, and the low profile cuts the air pretty decent for an '88 model.



We have about 100K on the 5er, bought it new in '88, and been all over the USA with it. I usually drive pretty conservatively, but don't spare the truck in the steep mountain grades - can easily maintain 70 MPH in overdrive on the multi-lane California Sierra grades, such as I-80 between Sacramento and Reno - but any more, I just drop down into 5th gear at just under 60 MPH, and cruise along. Of course, that's easier on both the drivetrain AND the MPG... :-laf



Besides, the narrower and far more winding grades in Oregon don't permit speeds much above 45 MPH or so as a rule - so very few Ford/GM challenges available. :-laf



I always keep the truck tires at 80 PSI, and trailer at 60 PSI when towing - brakes all well adjusted, and rolling resistance about as low as it gets, every little bit helps - and it will be interesting to see what happens now without the Smarty, but the SS intake in the mix!

Gary, I get very similar mileage to you but I do have 4wd. cruising empty at 65 I turn in about 25 mpg hand calculated. I don't think the Smarty SS intake swap will do much to the milage. I got a mile or 2 better when I put in my Edge EZ & that stayed the same with the CaTCHER programs. If I recall, you are using your Comp for timing & that would be about the same as the EZ.

You're probably correct - my main interest is seeing how effective the SS intake is in offsetting the absence of the Smarty in similar driving...

Heater grid delete

Stefan, I recieved my heater grid delete today and installed it asap,looks good,was easy. Here are some pics

 

[Allnew2Me]

Hey Short Stacks, looking good with that delete installed. Are you going to leave it on all year or change it back to the heaters in winter? I hear Reno can be a bit brisk! Also, can I assume that my intake has arrived with your delete? Oh Boy! I get to put mine on now.

 

[darkhorse]

That looks so much more elegant than my HighRam that the bling factor along nearly justifies the price. I bet the flow on this one is almost identical to the CFM+ but I'm partial to the stainless.

 

[JasonCzerak]

Are they going to make that setup with a 3. 5" inlet? For those of us with bigger intercoolers? The banks thing is so FUGY

 

[DFleming]

I would like to know the DTT intake compares to the CFM+ in flow rates and or horsepower gains, I do like the fact that it is steel insted of plastic or what ever it is.
