Thanks, TDR Staff

just sold my 96. have some parts on ebay

Difference between Comp and Drag Comp??

Not much road time on them yet, but so far I'm VERY impressed. This is my first set of aftermarket injectors, so I don't have much to compare them to, except for my EZ. I was very concerned about how high the egt's would be with 100hp injectors, but that turned out to be no big deal at all.



I had initially unplugged the EZ's data connection (to save the stock clutch) and left the MAP portion plugged in to keep the boost fooler. After I fired it up for the first time and all the lines re-primed, I couldn't believe how smooth the truck sounded at idle! I had a slight "romp-romp-romp" when feathering the clutch while backing out of the garage, but with the pedal all the way in or out the idle would smooth back out. Acceleration smoke is very controllable, probably more so than with just the EZ (it is only 25 deg F out though). Heavy acceleration with low boost would get more smoke than with the EZ, but once boost built (over 10psi) it was clean burning.



By the time I reached 90 mph on a full throttle acceleration run I had 32 psi of boost and egts were barely touching 1100 deg pre. This compares to 28-30psi and 1050 deg with the EZ and 22-24 psi and 1000-1100 deg stock. As far as power, I can break the duals loose with long-pedal only in third gear on dry pavement. The girlfriend talked me into plugging the EZ back in at the lowest setting, and that ended up breaking the rears loose in fourth and resulted in 34 psi and 1100 deg @ 90mph.



So, like I said, I'm very impressed. I wanted to add power but keep the driveability and towability and I think this should do it. The clutch holds for now, but I will be getting an SBC OFE in the near future. Of course, that would allow me to put in a DD UFM and a 40/35 turbo... . When will it end?!?!
 
Never ends!!!!!!!!!!!!!!!!!!!!!!!!! Only limited by $$$$$$$$$$$$. O'Ring head, cam, more fuel, more air, never ends... ... ... .....
 
I've had my EDMs in for two weeks now. They are awesome. thanks chris suttion for the install. I pulled with them a week ago. I had a load of 8 cows (9k lbs) and the trailer (6k) and the smoke and temps were very controllable. The highest my pryo ever got was 700 but unfortunately its installed post turbo and thats changing this week. Bottom line i pulled away from a freinds new Duramax going up the hills and i never even put my foot into it. :D
 
I'm looking closely at adding EDM IIs. Has anyone experienced adverse effects on cruise control operation with the combination of EZ and EDM II? Thanks In Advance
 
I was experimenting with that today, as a matter of fact. No problems whatsoever with the cruise. Rock solid.



I also got a chance to try a cold soaked start (0 deg F). One cycle of the grids and a little more cranking than with the stock injectors and she lit up and settled into an as-smooth-as-can-be-expected-at-zero-degrees idle without any romp-romp-romp. Clicking on the exhaust brake below 140 deg water temp will result in about 2-4 "romps" and then it will smooth out again.



Once everything warmed up the truck really ran smooth. Normally when the temps are below 15 F or so the engine sounds like it is hammering pretty hard from the timing advance. The temp never got above 10 deg. and the hammering wasn't anywhere near as bad as it was prior to the injectors.



Now if the ice would get off the roads so I could play with the extra power... .

Well I guess that depends on the size of your EDM's. My Mach 7's surge something fierce with the cruise on but I also make over 400hp on just injectors :)
 
Jeez, no sheet Sherlock. Mach 3's 125hp, Mach 7's 225hp??? Cruise control doesn't seem like much of an option when running something like that!
 
I was talkin on the "average" level. These Mach 3's old style 140HP and the dodgezilla turbo is a killer combination.



I am very pleased :)
 
Temps

Bob,



What kind of temps do you see with your Mach 3's and whatever box your running?? I have a DDUFM and just put in some Mach 2's. Temps warmed right up :eek: . Been thinking about a turbo choice. DodgeZilla would be on the lower end of the spectrum or maybe a KSB1-B on the upper end. I need to get some info on the DD Jammer.

It's a trade off of course. I don't want smoke so small turbo for the low end drivability. I want to be able to use the top end without problems.

Any info appreciated.

Mach 7's. Nate tell me more. Have any dyno #s on kill. Whats your egt's like. Boost & overall driveability. You can pm me if you want.

Kurt,



You know I have to stay a step ahead of everyone. Don and I tried a little different combo, at the very end of last year, and found a few lost ponies. I really have to find out what layed down on the truck before I can say they are definately better though. Boost is the same to +1psi (75psi). Egt's are about the same at 1500* max on the strip. Driveability is pretty poor on anything more than 1-1 but the temps were pretty high down in AZ and Vegas the last time I ran them.



We really need to get my modified pump together and tested as no matter what we need more fuel.
