Why doesn't anyone use the DD I & DD II's ???. It seems as if the jump from the 275's to the DD III's are pretty extreme. I'm just curious, that's all, I'm still stock and just playing my options... .

<font color=blue>There are several people that use those levels. I can think of two off the top of my head that I know personally. Ramkids has DDI's and MarkCuda has DDII's. I could prolly think of some others, but alot of people either have 275's or bite the bullet on the III's.
 
Ah, finally I don't regret only going with the DDI's. They are a bit hotter than 275's but still don't take the truck into orbit by themselves.

As to max hp, I am quite happy when I combine the DDI's with the hot PE.

When the PE is off I get the advantage of it's internal boost module which allows the DD elbow mod to unleash enough to make me happy and still not slip the clutch.

As to snow, the L/S rearend is more a problem than the extra hp when the PE is off. I will not drive with the PE on in the snow ever!! (not the PE fault, rather the L/S rear trying to apply all the power in any direction it wants to)

With the PE on level 1 I rarely slip the stock clutch but enjoy the extra power.

With the PE on level 2 I have to manage the hp being applied to the clutch and be mindful of where I point the smoke generator.

The hot PE level 3 is only applied during passing situations when the RPM is over 2 grand. Some day I'll install a real clutch but for now this all works for me... !

I dynoed both about 9 mo. ago. This was done on a older dynojet 248c. After dynoing on some other dyno,s i realized that this dyno #,s read alittle low.

275 injectors 235hp(with boost module)

DDIII injectors 277hp

The last time i dynoed on a mustang dyno i got 525hp/1072torque. I,m going to try the PM3 offroad and the PE-EZ combination in the near future.

Good info sport bike. That's about what I'd expect for RV's vs. level III's. I was expecting up to 50hp difference. Due to limited gain due to air shortage it isn't quite that big, but close.

The debate is: What limits the gain realized with bigger injectors? Air? or Fuel Atomization? I'm buying the "air" side of the debate myself. Although a pretty good argument can be made for better burn with better fuel atomization -- but even then I still bet more gain is to be had with more air.

Still liking the 275s with the original PM. Although I was really bummed when I couldn't run away from the 360ci gasser I lined up with the other night... he had me by a nose and bailed before I could wind him in at the top side. If it hadn't been for shifting I would have had him by a nose.

Speaking of the DDIII's "smoke" characteristics, I installed the Banks High-Ram Air Intake on my truck and it really cut down on the amount of smoke I get from my DDIII's. The reason might be because it's about twice the size of the OEM Intake Manifold.

BLKDEMON,

How much did the Bank's High Ram cost? Do you feel it's worth the money? Thanks.

John you're exactly right.
At work we extrude the rubber seals for the auto industry. We make our own face plates for the different profiles with the 2 Mitzubishi EDM's that we have. Then we have to run them through our Extrude Hone to polish them out. A few years back, a rookie Engineer grabbed a face plate that hadn't been extrude-honed and tried to use it. Spider webs of rubber were exiting the face plate, showing how valuable the extrude-hone process is in fine polishing.

I foresee some Government projects with injectors in the near future if I can get the correct diameter of wire needed for the EDM burn. The hard part will be machining a nest for the injector to sit in during the extrude-honing.

Thanks Vaughn,
I'm a little skeptical as well. Take a look at all the bends in the system from the turbo to the intake... a lot more can be done there than just at the intake horn. It might be worth a try, but I've got other things to do first (like a VGT turbo or something). The high ram is on my list next to the ATS manifold as far as functionality. But who knows...

glad toi see others doing the G-jobs #ad


Isn't Banks' claim a 58% reduction in pressure drop? I'm more interested in the actual pressure drop for each manifold - not the percentage reduction. 58% of nothing is still nothing. Not really a cost effective change IMO.

To Mark in Nebraska,
Before I ask you my question on 275RV injectors, I want to tell you, as a California born boy, the time we spent on a farm in Nebraska(Tildon, Antelope County, 1976-77, the coldest and dryest [no snow] winter in the history of the Republic up to that time,-70 degrees with wind chill) was one of the best experiences in my life! I had to have battery-heated socks, and my cars' radiator was plugged in to 110v every night.
I loved Nebraska, but the rest of my family were California sea-bum types and hated it so I had to pack up an move back after only a year. #ad

Anyway, my question is this: I have a stock Auto transmission with an PE-EZ and 4:10's. It's a considerable improvement over stock, however, I am still not really happy. Sure, I don't expect to blow away a 5. 0 Mustang,(I was smoked by one the other morning-embarrassing) but I do expect to keep up with a a Chevy 350 4x4, which I couldn't do this afternoon. #ad

So, will 275's + my EZ give me an edge without blowing my transmission?
Thanks , Bob

Banks' High Ram doesn't seem to have any noticeable impact on power, spoolup or EGTs, according to Rob Hanson who put one on recently. He has a 99 QC 3500 4x4 with 4. 10 gears, blue box & Stage 3 injectors. 4" exhaust and stock (soon to be changed) turbo housing.

Let me start by saying that I did not dyno before and after... but I felt no appreciable change in performance after installing the High Ram.
As far as EGTs and boost, I saw no real change. The problem is this... unless you do something like video the gauges on the exact same road, same temps, same winds, same speeds, etc, the information is skewed, IMO. The change was less on EGTs than what I saw with my cowl induction hood.
Good news: I am very happy with it for two reasons... not many out there, and I think it looks cool. To each their own!

RobbyRam,

Not only is Nebraska a great place to live, we have a real football conference (Big 12) -- not a bunch of wannabes. #ad


I don't know enough about the PE-EZ to say for sure, except that you'll definitely see an improvement with the 275s. I could keep up with (or outrun) the 350 gassers with my original PowerMax and stock injectors -- unless the gasser had some performance improvements. With the DDIIIs I could outrun them easily, and give the 5. 0s a run for their money if I could get a jump off the line. Now with the 275s and original PM I'm having to adjust my thinking back to "this is a truck, not a racecar". Although it's still pretty darned fast. Had a Toyota with some GT enhancements try to run with me a couple days ago -- I was faster. But I will say when that remote (why is that THERE!) stoplight turned red he could stop that little car and I had to make the "run it" decision #ad
(no traffic anywhere -- or I wouldn't have been playing, have no idea why the light changed). No way 8000lbs (winter weight) was gonna decelerate from 100 to 0 in 100 yds. If there'd been traffic it was ditch time.

I guess what I'm saying is you have to get pretty radical to make a truck this size run with sports cars; but we can outrun the stock gasser trucks pretty easily if their anywhere near the same weight.

I would like to no,What is the best injectors to run with a va and boost module?I am looking at 275s. Thanks Joe.

joe i have 275's wit ha va and they are a good combo , i should have gotten the DD stage 1's , still waiting to get the part number for the marine 300's though.

i think you would be happy with the 275's and the VA /boost module , thats my everyday driving combo ,but with the winter i pull the VA , don't need the extra power in the snow except when i have my snowmobile trailer on the rear . but i do have a hot power edge sitting on my column just incase i run across a pesky brand x that needs to be spanked ... #ad
