Tow rig setup

[NyCowboy87]

Ok I know this topic has been beat to death, but I'm going to ask anyway, because I want some real world feedback and opinions.
I have a 01 6 speed truck currently with an adrenaline, 38r, reg. return and of course intake/exhaust. I'm in the market for some injectors and tunes to wake it up a bit more. I'm pretty sure the truck has a edge 100hp program in it (came with it when I bought it last year and it's hotter than I'd like it to be)
I've called around and have talked to a bunch of people on what injectors to go with and have gotten anything from stage ones, 180/30's 200/30's and 238/100's. Truck is pretty much a tow mule hauling horses and when it's not on the horse trailer it's hooked to the flat deck hauling hay or my pulling truck (whenever that will be finished) So what's everyone's opinion? Not looking to set the world on fire with it just want cooler temps towing and a bit more power towing to hang with my dads new 6.7.

Regardless of what you do, you should first get some custom tunes for your truck. Years ago, in my '02 auto, I had run edge that someone let me borrow, and the 80 was the most tolerable, but not as smooth as custom and did nothing for the tranny.

I have the same year/configuration as you, including 6 speed. Do you want to put a clutch in it or not?

If not I am not sure how much injector you can put in before you will slip the clutch, especially towing heavy.

I know for a fact with 238/100s and g3arh3ads #4 street muscle, your stock clutch will not hold if you get into it above 2000 rpms, even empty. So I guess it comes down to whether or not you want to put a clutch in it. If not, Im not sure how much above 160cc AC's you can go before you'll max out the stock clutch.

And at the same time, their #4 street muscle with 238/100s runs really nicely with a 38R, even up long grades. I DD that file.

Guess I should have said earlier that new tunes were coming weather I get injectors or not, been in the 7.3 world a looong time and know the benefits of a real chip vs a programmer. I've just been running what I have to save some coin until I got the other vehicles paid off. Also should have mentioned I already have a valair single disc rated for 450hp and am not afraid to put a dual disc in it if needed.

I thought I'd recognized your handle from PSN days. But I could be wrong. Matt at g3arh3ad prefers 238/80s for heavy towing over 100s. Though injector theory says 100s should be cooler. Ultimately it will come down to tuning. I haven't gotten to pull anything heavy yet, too many other projects going on, but their #4 file is extremely nice and cool, even during long grades, and acceleratingredients up said grades.

The 38R lights quick with the 6speed and what I have, which is nice. Also seem do be doing pretty well on fuel.

Have you picked a tuner yet? A discussion with them and what they like to tune was where I started.

Though again in theory, a 175/80 a code injector should have better IP than my hybrid, and should be more efficient.

 

[mikeeg02]

Do you want to/plan to stick with the 38R? When I talked to Carson Stauffer the other day, he recommended upgrading to a t4 369sxe, said it should do better and better cooler with what I have towing and on the big end.

 

[Tim @ P.I.S.]

A good set of 160/30's

I really like my 175/80 other than the new HPOP can not keep up with them. Just a "better than stock" replacement but even at 3.0ms it cant make more than 2800 psi at 75+% duty....Apparently the 175's are super oil hungry.

I wish I had gone with a hybrid.

I run PHP's hottest tune 100% of the time. never have EGT issues.

My 450hp rated South Bend holds up just fine.

Either keep the stock 38R wheel or do the 6x6 blade billet wheel. Do not get the 11 blade wheel made for the 38R, you will not like it towing. Slower spool and runs hotter while cruising and climbing grades.

If you go T-4 I wouldn't go bigger than a 366 sxe. a 364.5sxe might even be a better choice if this is strictly a tow pig. Good to about 500 hp and will spool super fast.

On average im pulling about 8K, Washington State Mt passes are where my experience comes from.

Unlimited stage 1.5's. In my opinion they make an awesome towing setup. Low egt minimal smoke and. They have a lifetime warranty.

 

[NyCowboy87]

Yes I plan on sticking with the 38r, although I'm not overly impressed by it now, I just like the fact it's a direct bolt on and I'm using the ebpv as an exhaust brake which is very nice to have.
I've always used swamps tunes in the past for the hot trucks that I've built (450/400's with a big single, twins and even the triples) and Jonathan has done a super job with those setups. He recommended a 200/30 injector for this.

I would go with 200/30's hands down be a solid 450hp aetup and should run clean

 

[TyCorr]

Yea, you would have more tuning flexibility eith the 200/30. You could demand more icp when its pedaling a hill and not have to worry about icp codes due to lack of oil.

I like 80% or 200% nozzles best but a 30% is probably sufficient. I just wonder with a 200/80 if you couldnt get boost quicker since you will lose it on shifts. Jam the same amount of fuel in with less pw.

 

[TyCorr]

@carport mechanic- i had the same issue. My 175/80s were drinking all my oil especially towing heavier. If i hit a hill towing, forget it.

 

[NyCowboy87]

oil.

That was my thinking, but I've personally never tuned a truck. I could care less if it smoked a little between shifts, can't be any worse than it is now.

Then there's always the train of though, if you're paying for a hybrid injector with an 80% nozzle, why not just get a 238 or 250. They usually are the same price. Have them tuned or detuned to suit your needs, but also have room to grow later or if you decide you want to hot rod a little empty.

 

[NyCowboy87]

Exactly, I guess I just don't understand why it's hard to detune a larger set. I guess at that point the injection event has to be just about perfect or things could get outta hand quickly, which is probably why tuners want something smaller.

I think that's the case with 200% + nozzles, though tuners are becoming more accustomed to them, and even more live tuning is always best to survive.

I don't think you'll find anyone having trouble detuning a 238/80 to fit your needs. I know on my #4 file from g3arh3ad, pulse width is limited to just below 3ms if I remember right. And egts are absolutely perfect to not have to watch the Pyro meter, again even lower rpm and accelerating up the large mountain here.

Funny you guys mention oil hungry 175/80s.
I can set my CEL on a hot tune towing heavy.
For low icp.
I'm even running an adrenaline and it will do that...

I sometimes wish I went hybrids too. 238/80 .

That was a concern with mine, and people will say all day long 175/80s will run on T500s and adrenalines, but nobody could give hard numbers of what it would hold on the ICP side. I did ask a couple forum members but nobody data logged.

I did some test runs last night and my T500 and 238/100s will hold over 3000 ICP at ~3 ms of pulse width. I can get the actual, but thats off memory from last night. I had an IPR issue I had to deal with so I wasnt paying close enough attention to how much above 3000 it was.

 

[Swaan]

Yeah I don't think my adrenaline can keep up with thses pis 175/80s .it's fine on a tow tune but on my all out it or any of my high hp tunes she runs short .

 

[CarportMechanic]

Is there a single pump that can keep up with these 175/80's?

Im thinking the Adrenaline and HB Jr. are pretty close flow wise.

Maybe the Honey Badger Sr?

Otherwise whats the options? Twin pumps or a Gen 3?
