Engine/Transmission (1998.5 - 2002) horsepower upgrades. What is best?

[ecv2001]

Alittle about what i'm doing. Any feed back would be appreciated.

I've got a 2001 ho 6 speed. I have installed a 4" exhaust and have a jacobs brake.

I want to add about a 100 horsepower and a pyro gauge.

are the bullydog stage 3 injectors a good way to go. ?

I am on a budget of about 800. 00 or so.

Also on the pyro gauge what is it going to take to install the sensor. can it mount on the elbow were the brake is sitting or go on the down side of the brake?

Thanks. happy new year!!!

Welcome Jim,

Most people, me included, install the pyro right in the exhaust manifold. Usually the pyro comes with instructions... ... ... be sure to measure twice and cut-once!



Additionally, 100 horsepower is going to tax your clutch if you drive like a hammer-head! So plan on switching to a better clutch(Southbend) sometime soon.



BD3's are a good deal, I will be switching from DD2's to BD3's soon. Another alternative would be to install either an Edge Comp, or an Edge EZ. An EZ will give you about 50-60 HP at the wheels and a Comp will give you from 50-130 at the wheels (the Comp is adjustable).



Since your starting out, I would suggest one of the boxes, then a clutch, then BD3's... ... .....



HTH,

Best of luck,

George



BTW, fill-in your usercp so we know where your from, etc.....

Firemanemt,



Welcome to the Board. I agree with Batman -- start with a Box. You can get a Power Edge Comp and stay in your budget.



The other suggestion to get your 100 hp is to Install a Power Edge EZ box and then some 275RV injectors. . This route will give you slightly better mileage. It will run a little more $$. Added benefits is that you can remove the PE EZ in minutes when your truck needs to go in for Dealer service. The Comp is harder to remove and you must splice into the injection pump wire. If down the road you have Injection pump related problems they may not be covered by warranty.



Installing a Stage 3 (100HP) Injectors will give you the HP but are not as responsive as a box plus you will have more Bottom end smoke to deal with. Boxes First Big injectors Later!



Either route at 100 HP upgrade you will need a clutch upgrade soon. But you can cross that bridge when you get there.



Happy Bombing!!

DD2's are gonna give you about 90 HP on the ETH, DD3's will give you about 115-120. The Comp box MIGHT get you 70 total, but not near the 120 it will give an ETC. Why fight the high EGT of a Comp anyway? The injectors will give you more useable towing power. The box also adds more low end power than just the injectors, which is hard for the clutch to hold. I would think you can get away with DD2's for quite a while driving sensibly, but most slip the clutch soon with a box. The EZ and 275 combo runs VERY nice, but has the low end to eat the clutch if you hammer the power at lower RPM. Injectors and minor fueling boxes (like the EZ, VA, PUCK) are the way to get useable power. Tapping the pump wire on an ETH is only good for 30 HP and raises EGT quite a bit.



If it were my truck I would add the DD2's if towing, DD3's if little or light towing.



Put the probe for the pyro in the exhuast manifold. If adding power it NEEDS to be in the manifold.

I'll have to agree with what LSMITH said, add the DDII's for about 90 hp. Your clutch should live with this unless you go out and *try* to make it slip. For your budget ($800) you should be able to get the II's and a pyro with some change left over. You will not be able to get III's and a pyro *and* the clutch that you most likely will need from the III's.



From what I have personally seen the injectors add more power from 2000rpm on up which appears to be easier on the clutch than the big boost that the boxes give below 2000rpm.



Good Luck and BOMB on.

< Added on Edit > Somebody correctly pointed out that the injectors may cause overboost and a limp mode problem. You can solve this with a Practical Solutions boost module for about $150, so you're still in budget. $500 for injectors, $150 for boost module, and $150 for pyro, although I'm sure you can beat that price on injectors if you shop around.

 

[Stefan Kondolay]

I would run a Edge Comp ($659 approx) and a pyro ($150 approx). If you do big injectors first there is a good chance that your truck will go into limp mode and make no power. The comp will give you over 100hp and will keep you within your budget.

 

[LSMITH]

The DD2's come with a boost module, there for no limp mode.

 

[mikel]

I was not aware that the injectors came with a boost module. Thanks for the heads up!

I still say and so do dozens of my customers... Box First then injectors. With the EZ and 275rvs you won't have much smoke or egt issues. and it is alot more fun to drive having a Crisp and responsive bottom end. If you can't be nice to your clutch then only an EZ for now will make you very Happy.



Unless you are installing the injectors yourself you may want to add in a Installation Fee.

EZ & 275's...

I agree with Kwikkurt - that's the setup I have.



Throttle response is super crisp. Good combination of low end and top end. AND, most importantly to me, this combination is, A) super stealthy (EZ is easily removed), and B) this is about is tickled as a manual transmission can get before the clutch is really taxed. An EZ and DD2's may hold for awhile, but to me its not worth having to replace a clutch for the difference in power between an EZ & 275's versus an EZ and DD2's.



Last thing is, this combo cost me ($110 injectors including shipping + $495 EZ including shipping + $65 clean & matching injectors) ~ $670. Now that's bang for the stealth & reliability buck in my opinion. I'm running in the range of 300 h. p. and 625 lb. ft. at the rear tires (according to others with this set-up who've dyno'd).

Personally, I'd just add the EZ and pyro gauge (pre-turbo) and see if that's enough for ya. If not, upgrade your clutch then try larger injectors while retaining the EZ box.

my thoughts

I put in Stage 3 injectors (100 HP+) on my rig. I like them very much. They were very appreciated on a recent CA to VA and VA to CA trip over the XMas holiday (6000 + miles in all). The highest EGT I saw was 1200 degrees and that was just for a matter of seconds.

Everyone makes a case for "being able to remove the boxes" quickly. That is a true statement but they dealer would have to go through a bit of work ( and labor hours) to know that I have other than stock injectors. Yes, Yes they would know something was up when the touched the accelerator and the truck launched their head into the back window. My dealer is "cool" and works with me. I don't volunteer info about my mods but lets say they used my gauges to find my bad lift pump.



One thing to consider is your clutch. It is smaller and less robust than mine. I am stock but I am not an HO engine. My clutch works well with my current HP.



I simply love my injectors and would repeat the purchase even after reading everyone's input about the subject over the last year.

Upgrades!

You can see by my sig. what I have done. I would really like to go with injectors at this point but have been told the dd2's will cause high egts without a turbo upgrade???? It seems like alot of members have dd2 with the ez and no upgrade of the turbo. I would like injectors with the correct part number to keep it stealthy. Whats the best??



RichB

 

[LSMITH]

Rich, 2's should be fine without a turbo upgrade so long as you don't tow heavily. Your turbo will let you hit 1400+ pretty quickly with the 2's, but unless towing or very heavily loaded you can't keep them there long enough to hurt a thing.



If you are one of those guys that gets nervous at 1200* then no the 2's will not work at all.



An HX35 could probably be had for less than $400 with low miles on it if you keep an eye on the classifeds. It should bolt right up, and then you could run the 2's easily.



I have only used Diesel Dynamics injectors (2 sets) so I can't comment on the others, but I am totally satisfied with the DD injectors. The will probably make you a set of 2's with the stock part # if they don't have them on the shelf. There is no point to it though. The dealer WILL KNOW as soon as they take it across the lot that there is something up.

Rich,



I have pretty much the same setup as you and have no ill effects of high EGT. I have the HY turbo and used a turnbuckle to hold the wastegate closed a bit more for higher boost (28-30 PSI). Search on 'turnbuckle' if you haven't done so. DD2s and an EZ are a great combo which is a significent and safe power mod you'll love. I do plan on a PDR HX35 in the future, but the little HY is holding just fine right now.

I will add ont to the injector group. With DD3's and the little HY I never see temps above 1200 unless I turn the box on. I never drive with the box on unles I am playing as I love the way the 3's feel stock. However since I have a ETC I can't comment on how 3's are in a ETH. I would have to say to do what the ETH guys recommend as they will know best. Good luck with whatever you choose as you can't go wrong either way.
