Engine/Transmission (1998.5 - 2002) Mach 1.6 or mach 2's?

[MDale]

Since there is no core charge on injectors this month I'm going to get some. I'm trying to choose between the 1. 6 or the 2's. The big question is will my stock clutch hold with the mach 2's if I only use the EZ as a boost fooler, Or with the EZ on the lowest setting? I don't tow much, mostly highway miles and I want to beable to play around with some chevys and fords. Also better MPG is always a good thing, and money is tight so I can't upgrade the clutch at this time. I hope you guys can really help my out on this I've been looking for the answer all day.

Thanks, I can't wait to get them.

It depends on how hard you push it. DDIIs and an EZ did the push for my auto. With the stock clutch I'd say you would be safe with the 1. * but pushing the envelope with anything larger. A couple slipped clutch launches with any power mod will eventally lead to failure. It's your money, pay to play.

BTW: Who is selling injectors w/o core?

 

[OPoole]

Thanks MDale you will love your new F1 injectors.

Always go with bigger when you can. Heck, I am running Mach 3's on a stock clutch with the Diesel Dynamics TTPM. Of course, the stock clutch is not really happy right now. Hopefully this month will upgrade to a 13" OFE.

Chances are your clutch won't hang with the EZ and the injectors. The first time I did a fifth gear roll on (clutch foot on the floor, empty truck) my clutch went away. And once it slips, it glazes over and will only get worse. So then you feather the throttle to prevent any further slipping so you don't trash your flywheel, and you're now putting down less power than you could stock. Some of the 6-speed clutches could hang at these power levels, but the majority can't. The composition of the clutches Dodge used varied greatly, so some got lucky, most didn't. Mine had led a fairly easy life and it still slipped. You can try it, but remember that it'll never be the same if it slips under power.



As far as the EZ is concerned, levels 1-3 all produce about the same horsepower. The maximum fueling is the same for all levels. What changes is the psi of boost at which fuel is increased. Pretty much for smoke control only. Running it as a boost fooler may be your best bet. You won't get that EZ bottom end hit, but you will get some really smooth power with just the injectors.



Once you get the clutch in, that combo will be a blast! Nice and safe egt-wise with awesome power (just watch the fuel pressure).



Good luck!

My clutch slipped with just the EZ. So if you already are running an EZ, my bet is that you will go over the top with the injectors on top of the EZ. And like PC12Driver said, after the first slip it only gets worse. It was no fun laying off the throttle after making the power - kinda defeats the purpose of the performance upgrade in the first place.

I slipped mine within ten minutes after adding rv275's to the ez... . The 1. 6's... you better drive really light footed... :-laf

What are the egt differences going to be between the 1. 6's and 2's?I am trying to decide as well. I use the truck to tow alot so maybe the 1. 6's would be better,but everyone has told me go bigger than you think you need. I need a clutch first though.

My stocker does battle with mach FOURS this month! Highlights at eleven.....

Ok I got some Mach 2's from powerbypoole.com, I'm going to run with out the EZ at first and see how things go. hopefully I won't slip it. Does anybody think I'll need to go to a 14cm exhuast housing? thanks for the help. The Injectors sould be here next week. thanks again to OPoole.

 

[PC12Driver]

Mach 2's + EZ = no problem with the stock turbo. Max I could get was 1200-1250, which according to Cummins, you can hold all day.



My advice would be to try the combo before you mess with the turbo. If your egts are in control, don't mess with it. The 14cm housing will move the RPM that your turbo lights off at up by about 200 rpm. You'd be trading bottom end spool for top end cooling that you probably won't need. So if you're not overtemping, there's no real need to upgrade the turbo.

Well, I got my Mach2's Tuesday and installed that night and am very happy with them. Much faster spool up(32psi from 28Psi before injectors), EGT 800F max post turbo,50 to 75 lower EGT at 60mph, and nice smooth power. Tonight I hooked up my EZ also lotssssss of smoke ,and the stock clutch held! But the fuel pressure drops like a rock to 3-4psi before I let up, and Egt got 900F. But it puts real hard between 2000 to 3000Rpms. I'm going to show the guys at work tomorrow, then unhook the the EZ until IRP. Thanks guys.

 

[OPoole]

Gald your happy with the Mach 2s and the no core charge is nice also. Maybe try a big Line kit next for that fuel press. Or maybe a RASP pump i am going to raffle one off for $10. 00 tickets.

OPoole is right about the big fuel lines. I raised my WOT fuel pressure by 6 psi simply changing to 8 AN fittings & lines from the lift pump forward & that's with the stock banjo bolt & line still on the lift pump inlet.

 

[DjFire07]

darkhorse, where'd you get your fittings and lines? I just replaced my stock banjos which only netted me 1 psi. I can still bring it down to 8 psi and I haven't added my 1. 6's yet.

hohn I can't wait till you get your don's 4s in you been talking about em for a while.

Also I admire you for knowing so much and still being kinda consevative like me: no wire tap box quadzilla hybrid instead of b1 or super 40.



Very few that are as knowlegable and don't show their butts like RAser dooly sl ed pooler and comp453.



start a thread on your setup as soon as you get the 4s



im looking at catcher then 4s then b1-2 or htb2 then and of course con ofe some where in the middle THANKS hohn

by the way anyone know what a power puck does is it timing advance and fuel? it seems simular to the edge at 50+ considering it doesn't come with a boost fitting.

 

[MDale]

I have an EEP pusher pump kit sitting in the garage, so I'll see want that does for the fuel pressure first, then get the big line kit if I need it. Is it just me or is the #6 injector line a PITA to get. It took just as long to do that one injector as it did to do all the rest!

I got mine from Scotty but all the parts are listed in the Summit catalogue. Just don't get the "Webber" fittings. They are to restrictive.
