Engine/Transmission (1998.5 - 2002) Boost fooler or Edge Box or Injectors

[Leathl_WS6]

I have some gauges on order. I am considering the Edge comp. Injectors or the Catcher.



Truck is a 1999 Six Speed I'm guessing its the HO model.



I really want to get injectors first. I am thinking about the 1. 6's. I like the idea of 90 more hp. Over the 50 for the edge or the 66 for the catcher.



I tow a boat on occasion 10. 5k a car some times 5k, but mostly it will be a daily driver.



It was recommened that you run some type of boost fooler or elbow with the injectors to up the boost. Can I accomplish this with out buying a $500 box?



Is there a boost fooler that is less expensive? Like on a gas motor you just put a $50. 00 boost controller on and you can then adjust the boost how ever high you want it.



What is an elbow? where can I get it? and what exactly does it do?



Thanks guys. I have been reading alot on here and have found some great information.

The HO's didn't start until the 2001 model year, you have a 235 hp 6 speed, that transmission has the 1 1/4 inch input shaft also, no big deal, just not as beefy as the later ones.



When I got my truck I started with the Comp box, it does the boost fooling and everything and I like the adjustability, that way when someone else drives it I can turn it down. I recently added injectors and upgraded the box to the Drag version. Someone does make a boost fooler only but why pay for that and then pay for a box that'll do it later. Once you start you won't stop adding power so just do it right the first time.



If you go with the catcher it takes care of the boost for you, from everything I've heard the catcher and injectors are a nice setup.

What kind of power are you shooting for? A Comp and 90hp injectors will require fuel system upgrades and a bigger turbo, and should put you in the low to mid 400hp range.



Do a search, there has been talk that the Catcher and the Comp don't work well together. The Comp by itself on your truck will make ~115rwhp gain.

A comp box alone will give you approx 120hp (Fueling, timing and boost fooling)

if you tow, the comp box is a good choice because you can turn it down

to keep your egt's under control

injectors are good too but your stuck with that power level (unless you change them) for larger ones or smaller ones



IMO the edge comp box is the best bang for the buck

Leathl_WS6,



What Turbo Tim said. The boost elbow comes with an Edge EZ or comp, not with a Catcher. It will allow the boost to exceed the stock ~22 psi to about ~32 psi. Boost fooling is telling the ECM that the boost never exceeds stock parameters. Edge and Catcher do this. If you don't go with one of those, you can get a boost fooler only.



I have the Mach 1. 6 and Comp. The stock HX35 is acceptable for daily driving, though care is required if you want to take off without making smoke, as is my preference. You can also tow with this combination - box turned down, eye on EGT gauge.



The HX35, even with my opened up intake and exhaust, still does not allow the full potential of the fuel available with this combo. In other words, with the Comp on levels 4 or 5, empty truck, hammering into a grade, this turbo can't clear up the smoke and EGTs will become an issue in a few seconds.



A bigger turbo addresses those issues on the top end of the performance curve, but tends to trade off quick spool up in daily driving. I'm not sure what is the ideal solution for those two operating requirements.

Twins?

Bigger intercooler?

Water-Methanol injection?

Money, money, money?



I think it's money :-laf

P. S. Before you go over-fueling your truck, you might want to make sure that you can reliably get enough fuel from the tank to the injection pump



Happiness is:

A lift pump that sucks

A turbo that blows

And hummin' Cummins

The 1. 6s are a great injector. I ran them for several months before stepping it up again. Mileage is great with them and they really add the power too.



I'd just get an Edge EZ or Van Aaken box if I were you instead of messing with a stand-alone boost fooler. You'll be wasting money in the long run because eventually you'll want more. I've had good luck with my EZ but in most cases, the Van Aaken box is cheaper and gives comparable power increases. I wouldn't mind trying one even now.



I'm just not convinced on the Mad ECM idea yet. All of your boxes that are available are designed to work with the stock ECM and the stock injector pump. It's now known that the Mad doesn't play well with other boxes that add timing. And too much timing is not a good idea.



Of course, you can always just run injectors only and leave the turbo alone. Without a boost elbow, you're boost will stay in the low 20s and you shouldn't throw any overboost codes.



By the way, a boost elbow is the little brass elbow that screws into the front of your turbo. The wastegate line slips onto it. Fueling and timing boxes come with either an adjustable elbow or one that has a small hole drilled into it so more air will bleed off, thus causing the wastegate to open later and create more boost.



Whatever you do, go with the 1. 6s, you won't be disappointed. Olee Poole is a nice person to deal with:



Power by Poole



Oh yeah, and if you go with injectors AND a box, you're gonna have to upgrade the clutch before you can ever make use of the power. Also, an Edge Comp alone will probably make the clutch slip. With 90hp injectors, you would probably be ok. Mine slipped with and EZ and 1. 6s.

Thanks for all the very helpful replies.



I am kind of a speed junkie. I am going to try and reserve myself with this truck.



I have a WS6 that I have put a lot of money into chasing the speed deamons. It runs low 11 second 1/4 mile at 121mph. As well as a speed boat that runs almost 80mph.



I like the idea of 100 maybe 150 more hp. I know I don't want to upgrade turbos, fuel systems or get real crazy with this truck. I want to keep it relaible but I also want to add some decent power. It already has a 4 inch exhaust. and a KN filter. I know those arent suggested but will it be good enough for what I am tring to do.



That being said can I get away with just the injectors? Would I be better off with the comp box? I know the EZ would not be enough for me. nor would injectors smaller than the 1. 6's.



Thanks Rob

Let me reiterate that a 120hp Comp box will very likely make your clutch slip. Even Edge suggests a clutch upgrade if you are going to use this box. But depending on what you do with your truck, a slipping clutch might not matter. It's only going to slip if you have the truck under load or if you abuse it.

The problem with the CaTCHER stacked with a Comp is that they both are trying to control timing. There is a "special" version of the CaTCHER just for use with the comp &/or extremely large injectors. The advantage that the CaTCHER has over other fueling programs is it's extremely rapid throttle response. I don't think it can be beat in that regard. It works well with fueling only boxes such as the offerings from Blue Chip or TST. It works best of all with moderately large injectors like Mach 4's.

 

[Leathl_WS6]

How would the catcher work with the 1. 6's? Would that be a good fit. Maybe I will just go woth the comp for now.



Which way will give me the least amount of smoke for a daily driver?



The clutch was just replaced with a better one but I did not do it. so i don't know what clutch it was or how good it was. The seller told me it was a sindered iron disc.

The CaTCHER works very well with Mach 1. 6's. I ran mine with 1. 5's for over a year & found it very good. Granted, the Comp is less expensive but the CaTCHER has such good throttle responce that a number of folks have sold their Comps after getting the CaTCHER.

Hey are there such things as boost elbows which you can control when they open? Such as one you could set to let enough air through to open the wastegate at 30psi?

There sure are. I believe Rip has them listed on his web site with a photo.

okay, lol. I see everyone with rip's 4'' exhaust in their signatures, but I dont see a link to their site.
