Engine/Transmission (1998.5 - 2002) Don M 1.5's, or DDII's?

[fox]

LKrueger, when my truck was set-up like the profile, we drove it to south west florida, summer of 03 and it produced a tank at 20. 5 mpg, then the next two were 22.

About 6 months later it had an attitude for a week or so. I never gave it much more thought until I checked mileage, and it was down.

I have tried several different injectors and comp box settings.

All mileage is hand calculated.

Currently, 16-17 is every day witha best high about 19-20. this is driving it very easy, which was not the way we did goint to florida. Ran 75 most of the way.

Then this past january we went back to SW florida and had a bunch of dead pedal issues coming home. And code 0216.

Now it is running very normal and feels very strong.

I need to check grounds and all connections.

There are many reasons to ?? the talents of the engineers who proofed the grounds and filters. ( none ).

I think they are still on the bottom of the learning curve, or they are hiding under it.

So far I have had to filter the APPS and need to do the same to the cigarette lighter/ phone charger plug. The noise is bad, and probably moves to the VP.

"there is a NWBombers get together the first weekend in June. "



AH! That's more like it!



I'll keep an eye out for the announcement on that one - wonder where it is in relation to the one this weekend in Enumclaw? Also wonder if it as comprehensive in scope, large turnout, Dyno runs, etc?



Depending on exact location, might travel thru Redmond myself - we'll hafta stay in touch...



Thanks for the info!

 

[snowracer69]

Guess I need to be more specific... I'm going to be in Redmond, OREGON by then.



The address for the one in June is "Arlington 98223" (don't wanna give out all the info on here, even though I'm sure they wouldn't mind). Like I said, it's pretty far north, but will probably be worth the trip.



You're gonna have to learn about us NW guys... you can throw as much crap our way as you want and we'll still welcome you with open beers.

 

[Gary - K7GLD]

I understood the Redmond bit, or figured I did - I'm in Canyon City, about 120 miles east of Redmond on hwy 26...



Thanks for other info...

 

[snowracer69]

Guess I'm the one confused... shoulda looked up Canyon City... always thought it was more up north, near the Columbia... learn somethin' new every day.

Doesn't look to be any question the 1. 5's would work well - remaining question is, would the 2's be TOO much for towing and EGT under load...



My gut feeling is that the 2's MIGHT be a stretch - I need a bit more input from other users - I don't really plan further power upgrades after this, and don't want to be forced to something like a larger turbo in order to live with, or get the most out of 2's. If that IS likely to be an issue, I'd rather go with 1. 5's...



Something about a piston meltdown from excessive EGT sorta ruins an outing!

I felt the same way and opted for the F1 Mach 1. 6's. My thinking was if I went with the M2's I would have to add a hybrid turbo.

I towed the 5r last weekend up I-5 and had no problems with egt's (of course it's only the freeway). They did however run just a bit warmer than the 275's, which was to be expected. The only thing different from the 275's as far as towing I can see is, that I'll be using 5th gear a little earlier on steep grades. BUT the egt's for us rowers are very manageable. BTW did I say how much love these sticks! They rock! Thanks Don!

Gary, I can't believe Bob hasn't chimed in on this topic. Bob told me that I could safely run a F1 2. 4 injector for towing. I had the stock turbo, boost fooler, power puck(sort of comparable to an ez). I had no issues towing a load of cattle. The only thing I had to upgrade was my clutch. Looks like you have already done that. My egt's were perfect for my application and towing. They were so perfect, that I went with bigger injectors because I do not tow very often. I would go at least with the F1 2 injector. Set your comp box on the ez power level when towing and enjoy!

 

[nutter3]

I have the DDII Jammers and really like them. I tow a 27ft enclosed snowmachine trailer with the PM3 set on 2 and dont have smoke or EGT issues.

 

[DLBurns]

I have the 1. 5's and changed out my HY for an HX35/12... this combo with my EZ box will flat get after it... I have not towed my fiver yet as I am still trying to sort out this APPS problem.

Last Dyno was 340 RWHP and 680 ft lbs torque... gonna dyno it again this weekend and see if there is any change.

I have a similar setup and would be interested as to what you do dyno this weekend. Please keep us informed. Phil

I usually drive around on 1x1 on the COMP box I'm a little curious what HP/TQ numbers I would have on the lower settings. At the Dyno I've only checked the high end.



Gary,

I can build some serious heat going up a steep, long 6-7% grade here in Colorado without a load. I know people around my area tow with stage 3 injectors provided they have enough turbo. Personally if my truck was primarily a tow vehicle I would be careful going beyond the M1. 5 /DD2 injector.

 

[DLBurns]

I will keep you guys posted... . My HP should be a little closer to 350 and my Torque seems a tad low also!

I guess I'll just try every dyno that I can find and then stick with the best numbers

They are all different!!

 

[Gary - K7GLD]

OK, as it now stands, I have committed to Rip Rook for an installed set of F1 1. 5's, and a 4 inch exhaust system involving dual baffling (mufflers) to avoid drone or resonance - these are to be of straight-thru design for low back pressure.



This was after lengthy discussion with Rip, and I still have 2 nagging concerns. One is that the 1. 5's are REALLY the maximum usable for my typical use and other associated mods - and the other relates to the use of a 3. 5 inch turbo downpipe whereas the rest of the system is 4 inch.



Rip claims the 3. 5 inch downpipe enhances low end torque, and is entirely suitable for up to 450 HP - my finished setup SHOULD be good for about 400 HP.



Rip comes highly recommended - and I sure hope he is correct on all counts here - I really DON'T wanna have any regrets or second thoughts after the time, $$$ and effort all this will involve...



Wish me luck!



OH, and I received quite a few (much appreciated!) offers for used injectors from this thread - I very much appreciate them all - but feel I really should buy the products from the guy installing them, in case of later issues that might occur.

 

[darkhorse]

Gary, I think you are going to be very pleased with the Mach 1. 5's. The power with your comp on 5x5 will be more than you can practically use for any thing but racing & it will be pushing the limits of your stock turbo. The standard 12 cm exhaust housing can be ported if your EGT's run high or you could go with a 14 cm housing. With the Mach 2's you would have trouble running the higher levels on your comp.

 

[Ram4Sam]

Rip's downpipe....

Gary, I have been following this thread with interest as I have been pondering similar mods. I thought Rip's exhaust had a 4" downpipe, is the 3. 5" downpipe something new or just an option?



Sam

 

[snowracer69]

It has to go small to come off the small turbo. The turbo is your major restriction, NOT the downpipe! The downpipe almost instantly goes to 4" after the turbo and the system should be 4" from there back.



Gary, if you'd ever get over that Cali attitude (you live in OR now, remember?) you'd find that the fellas in the NW are a great bunch of guys and we can be trusted (you seem EXTREMELY skeptical of us for some reason). Rip is one at the top of the list. He WILL TAKE CARE OF YOU NO MATTER WHAT! There are VERY VERY FEW vendors and products that I openly endorse (look at my sig... between Denis, Luke, and I, we have tried many thousands of dollars worth of stuff on these trucks from lots of different people!)... two of them are Rip Rook and Don's EDMs. You will never have a problem with either of them.



Hope to meet up with you this summer sometime.



Josh

"Gary, if you'd ever get over that Cali attitude (you live in OR now, remember?) you'd find that the fellas in the NW are a great bunch of guys and we can be trusted (you seem EXTREMELY skeptical of us for some reason). "



HEY, you've got me all wrong, I don't single out Oregonians - I'm skeptical of EVERYONE where lotsa $$$ are involved!



But seriously, it's pretty easy for misconceptions to arise in trying to communicate your expectations to someone else - in this case, I am focused upon trying thru these mods, to put my truck at the UPPER EDGE of it's potential. I don't mind turning down the Comp, or backing off the accellerator SLIGHTLY to maintain proper EGT in towing up steeper grades - but what I *don't* want, is to run out of fuel well before I run out of boost.



This is NOT about whether I "trust" Rip or not (he obviously has a GREAT reputation among his customers), and I sincerely apologize if that seems to be the case - it's only that I am anxious that *I* have properly communicated my hopes and expectations to him as to my goals. This truck is used mostly for towing, but also for around town and down the freeway empty - and I really want the most power and reliability possible out of it from these mods under ALL those conditions.



AS to these "northerners", let me tell ya, they have been absolutely the GREATEST bunch we have EVER encountered in our travels - and we travel a LOT!



We look forward to lots more of the same, and will try to fit in, "California attitude" and all!

Gary,



As far as the 3. 5" downpipe, unless you go to an HX40 size turbo, stick with the 3. 5". The exhaust housing on the stock turbo is the size limiter.



Rip will treat you right. Anytime you make mods to a vehicle you should do as much research as you can (and it sounds like you have), and then take your best shot. If you have talked your selection over with Rip, and he's in agreement with what your expected outcome will be, he will stand behind the sale. When you take your pickup out for a drive after the install, and you are not happy, let Rip know. He has always done right by me.



As far as the choice you have made, I think you will be happy. I ran mach 1. 5's for about a year, and with my stock HY35 turbo, it would get pretty toasty on 5x5. You have an HX35, so it won't get quite as hot. With the 1. 5's I could pretty much tow up anything I wanted with the comp on 3x5. At the top of some long hills on a hot day, I would sometimes roll a little out of the throttle. If the road got wet, I usually dropped the comp to 1x5, just so I wouldn't be tempted to use to much peddle when passing...

Hey Gary i just put in a set of F1 1. 5 over the weekend,Stock HX35 turbo,Catcher,and i can easly hit 1250 pre turbo,You will LOVE those 1. 5

 

[Gary - K7GLD]

OK, thanks guys, Paul and Machinist put the frosting on the cake - I'm sold - I'll let y'all know how it turns out - Rip has to wait for his next shipment of 1. 5's, then we'll set up the install. Sure wish he also had a dyno, but am planning on a trip up for Hoss's bomb bash in June, so might be able to get to the dyno outfit that Bob Hanson and crew used this last weekend for their party.



Thanks for all the input - it's been greatly appreciated and helpful to a worrier like me!
