HX35-12W, it was only the 2001 and 2002 automatics that had the small HY35. It was installed to meet emission standards!

AH well - not the first time I've been accused of lying!

Gets REAL amusing when I actually PROVE what I claim - and they STILL refuse to believe me! :-laf

My GCVW when towing loaded runs about 16,000, We regularly tow long, steep grades up at the 5000 foot level, 5th gear, at 55 mph - and I built the truck this way SPECIFICALLY so I would NOT be a slave to the gauges - and so far, it's working - believe it or not!

As to Dyno - Imageshack seems to have lost my last dyno run pic, but here's the one from the year before, only slightly lower - I'll have to dig out my originals and rescan them for Imageshack...

You have a VERY nice combination there, sir!! Basically, what I want, when my trans. and converter get replaced.:{

You have a VERY nice combination there, sir!! Basically, what I want, when my trans. and converter get replaced.

Thanks - I carefully attempted to arrive at my power level for the substantial RV towing in the mountains we normally travel to/thru. - and to get that done with mods evenly applied enough to not require frantic gauge monitoring or concern over potentially ugly side effects under heavy loads and steep grades - I have enough to do watching the road and traffic in those situations! :-laf

I started out with the High Output engine, and the 6 speed manual transmission, and went on from there - never been disappointed, BEST truck I've ever had, bar none - I still get 27 mpg traveling empty over 395 in widely varying hills and valleys between Reno and John Day eastern Oregon, and slightly over 17 mpg towing the 5er over the same stretch of road. Properly set up and maintained, these are GREAT trucks! Oo.

Do you fuel with imperial gallons?

plus 2x4

2x4's, 6 speed manuals, and 3.54's got pretty good mileage right out of the box. I can get 20 MPG with 4x4 and 4.10's if I stay around 60-64. Get 12.5-13.5 MPG on flat ground at 20,500 combine weight with a tall 5th wheel.

 

[Gary - K7GLD]

FOR the record, I DO NOT LIE - no need or motivation to do so - I visit and post here purely to LEARN what I can - and HELP where I can - My mpg figures are US gallons, hand figured - and yes, the BEST numbers attained, but the average figures are only slightly lower.

 

[SnoKing]

Gary - Some people have no sense of humor?

To OP, do not expect to see the same mileage figures that Gary posted. You have an Auto transmission and in 2002 the front differential lost the CAD(center axle disconnect), like earlier trucks, assuming you have a 4x4 you have more things turning up front that hurts mileage. You did not state your gear ratios, but the larger 285 tires might hurt mileage more than help. Like Gary says many question his mileage figures and cooling statements because hardly anyone else see that!

BTW, if I hooked up the Comp fuel wire to my VP-44 I would be maybe within 30 HP of Gary's numbers. 60HP injectors vs 90HP injectors, and maybe a bit better turbo with my PDR34-12W. However being the "SNOWFLAKE" I never felt the need to do that and put the extra strain of my pump, so I just run it was a timing box and to fool the ECM on over boost.

Over the years I have been here (14) very few do power mods expecting better mileage! Sometimes that happens, but it takes a lot of self control to add power and not use it to play hot rod truck. I love changing up mountains with the 5th wheel in tow and passing other RVers! I know it cost me some MPG, but life is to short to worry about it.

After we finish setting up my truck back in 2004 Bill at DTT was test driving it one day and said "this is one of the best driving mod'd truck he had driven. Nice power, but well behaved! Then with me behind the wheel, he called me a hot rod'er! But I was a kid back then only 60 years old!!!

I got 13.5 mpg half empty miles half at 25550 gvw on the truck scale one thing I've noticed about this truck it gets a little better pulling but worse running empty . I have since remodeled my flat bed head ache rack seems to be helping

It's no accident I get the mpg and related performance I do with my setup - I bought a HO, non 4x4, 6-speed manual truck because all my towing and driving are on pavement, and I didn't want or need the unwanted extra drag of the front 2 wheels, OR mods that required constant monitoring to avoid damage. I get all the power and performance I want in my application because I carefully TAILORED my mods to suit what *I* wanted, personally - and MANY of the mods I have done are posted in threads right here, on TDR - along WITH all the pictures and documentation during testing that most reasonable people can understand, as long as they are not more interested in debate and ridicule than giving their target a little credit for intelligence and reason.

Yeah, I read one last post from my self-styled critic - and no, you CAN'T persist in openly criticizing and ridiculing me, and then use the lame, tired old excuse "I was only kidding"...

NO, MOST others here will NOT get my results, because MOST don't spend the time *I* have testing to GET those results - and that's NOT my fault, or problem - but abusive guys who persist in shadowing me on this board to call into questions what I have tested and DONE - then when they get called out, pretend to "just be joking", are!

NOW, Snoflake - you can either be a MAN, and openly apologize for your poor behavior, JUST like you did your juvenile remarks - or just STAY in my scrap bin - YOU decide - I'll read one more of your posts, THEN we'll see where we go from here...

The ball is in YOUR court...

I've seen you on here for a lot of years if that's what mpg yer getting good for you my 98 24 regular would put down 19 mpg had figures and driving short trips around the farm . The bumblebee on the other hand weighs over 9000 with the sides close to 94 actually and is shoving 2 extra tires and a 1500 pound bed down the road . If I can get er to hit 17 I'll be so happy I'll pee myself .man she's got a lot of dang power and is the nicest truck to drive ive ever had . I also have to have 4wd and sometimes even have to throw a couple sets of iron on to get where I got to go.

 

[SnoKing]

Gary, I have followed your post for years and many others also. Your results are the exception and not the norm we see here on this and other forms. Some of it has to be driving style also. For years many have had to go beyond the HX35 to cool EGT's. So driving style has to play into your results a bit along with how heavy you tow!

And OK I am sorry if I was dogging you! But 999 out of 1000 others will not see the result that you spent years working on. No 4x4 Auto will see similar results. So the OP truck and yours are applies and oranges! I would love to have a 6 speed auto in my truck, I think I would see 2-3 MPG increase across the board. I am always gear bond one way or another with only 4 gears available, and yes a pull hard on a lot of hills in OD if I can stay above 60 MPH.

Snoflake

OK, accepted!

But no, I never HAVE stated that others with dissimilar trucks could precisely duplicate MY results - but on the other hand, all else being equal, even the 4x4, auto transmission guys most likely WOULD experience similar PERCENTAGE gains, the difference in OEM turbochargers between stick and auto trannies being an unknown potential issue. As to MPG, keep in mind that the Oregon speed limit is 55 mph - I normally pull the 5er at just under 60 mph where road conditions and traffic permit. I have 285 TOYO tires all around, and as I recall, a 3.88 differential. Yes, I corrected speedometer back when I had the Smarty, and in 10 mile long speedo check areas on the highways - as well as my GPS, am well under 1/10 of a mile off in accuracy in that distance.

I have absolutely NO way to judge as to how "unique" my specific truck might be in it's response to my personal specific mods - NOR do I have any particular reason to DOUBT that another truck just like mine would respond in the same way - all that would be simply guesswork, unfounded until actually tried! Here's a pic of the build sheet on my specific truck:

As to driving conditions while towing, the differential ratio and tire size place me right in the middle of my power band in 5th gear at 55 mph - so I have plenty of room to adjust speed as desired - and the EGT in the grades I mentioned is not at normal cruise, but rather when accelerating precisely to see HOW high I can force the EGT - fact is, slowing to about 45 mph on those grades, then flooring the pedal, the absolute HIGHEST EGT I can produce is about 1250 degrees - but normal sustained 55 mph cruise up the same grade usually puts EGT in the 1000 degree range.

NOW, as earlier stated, I come here for what education I can receive - or at some times, put on the table from my OWN direct, and often tested and documented experience - and it gets real frustrating when AFTER all that testing and documenting, I get accused of lying or exaggerating from others, not based on THEIR OWN actual direct testing or experience, but rather from long held "seat-of-pants" guesswork or prejudice. I'm here trying to help - not falsely somehow build up my own ego by pitiful lies or exaggeration! I'm NOT here to fight - but I'm not here meekly, to be used as anyone else's punching bag, either.

SO, Let's start over, and I would simply ask that ANYONE reading what I post here, check out how long I've been on this board, my post count, and the threads I have either started here on projects on my OWN truck, as well as involved participation in threads others have started

FAIR ENOUGH?

 

[SnoKing]

OK! I think your gears will be 3.54/6 or 4:10's.

For OP here is my build thread.

[Gary - K7GLD]

HMMMmmm - it's been quite a while since I was last back at the differential - 3.54 seems too high - could be 4.10, will have to check again to refresh my memory when weather improves - light snow here at the moment, too cold in the garage to crawl around on the floor. Come to think of it, I might be confusing the truck with the differential on the motorhome - it's 4.88, maybe got the numbers confused...

 

[SnoKing]

If you turned at or a little over 2000 at 60 in 6th with OEM tires you have 4:10's. Well under 2000 RPMs would be 3.54's

 

[Gary - K7GLD]

I don't remember what the RPM was with OEM tires (265), but with the 285's, I run about 1600 RPM at 60 mph - as near as I recall, going from the 265's to 285's dropped RPM by about 200...

Maybe it IS a 3.54 or so...

 

[Gary - K7GLD]

OH, and by the way, 2 more apologies are due, first, from me to the OP (as well as other readers here!), sorry to have so poorly degraded your original question and purpose of this thread, regardless of how well intended my own references to my own truck were intended, and,

second, to Snoking - several of my earlier responses were regrettably undignified, and NOT in keeping with the guidelines of this board, OR the image of my personality or character I'd like to think I possess - I have gone back and best I could, corrected those unwarranted references - but regardless, I still regret my behavior.

 

[SnoKing]

Gary I have no problem at this end. We are all here to share.

The funny thing about the Snoking name, is it came from our snowmobile years and my ability to find good snow for our group to ride on. Snowflakes are required to put snow in them mountains. At the time Washington only allowed 6 letters on vanity license plates so the W was 86'd.

I have a question on the build sheet where it says 100% galvanized steel. does that mean they looked like a Gleaner combine before paint ?
