Hey guys - replaced my injectors 1x with ISX holding my hand (where's the "flower" icon ) anyway Thinking of getting rid of my RV275's and going to +75 => +100HP ...... together with hx35/hx40 hybrid. That with my methanol/water kit should bring right at 275->425 HP which is as far I as think I should go without new headstuds/bigger turbo. So thinking a couple things. (1) What you think between full injector replacement or just nozzles ?? (2) Think of these http://www.cumminsperformanceparts.com/cpp-injectors.html + 100HP and http://www.dieselautopower.com/product_p/35-fslash-40%20turbo%20budget.htm or something else in some price point ? I haven';t seen anything and guys reckon they are on par with DDP. (3) ok main part/reason of this thread. http://mopar.mopar1973man.com/cummins/2ndgen24v/injectors/injectors.htm Step 10 of INSTALL. When retorqing the fuel line - what tool do you use as you can't use a normal socket etc due to the line ??? I think ISX and I just guestimated this part ......is there something that can be made or bought to go with the torque wrench ?? (4) ON torque wrenches was going to get these. One for inch pounds and one for ft pounds. The foot pound one acts as a calibrator also. Seem ok ??

Hey guys - replaced my injectors 1x with ISX holding my hand (where's the "flower" icon )

anyway

Thinking of getting rid of my RV275's and going to +75 => +100HP ...... together with hx35/hx40 hybrid.

So thinking a couple things.

(1) What you think between full injector replacement or just nozzles ??

Personally I prefer full injectors because with nozzles its suggested to pop test the injectors before installing.

(2) Think of these

http://www.cumminsperformanceparts.com/cpp-injectors.html + 100HP

and

http://www.dieselautopower.com/product_p/35-fslash-40%20turbo%20budget.htm

Did you get your EGT's down some with the water/meth?

or something else in some price point ? I haven';t seen anything and guys reckon they are on par with DDP.

(3) ok main part/reason of this thread.

Crows foot should work to get them tighten with a torque wrench. But like ISX I guess at the tension as well.

I've got 1/4" 3/8" and 1/2" torque wrenches... The 1/4" is inch/pounds and the other 2 are foot/pounds. Just good ol' cheap harbor freight wrenches...

THANKS

Coments in blue.

I just did some Cummins Performance Parts nozzles on some older bodies I had around. By the time I bought the nozzles and had the sticks popped and shimmed back to spec I only saved maybe 75 bucks.

My dad came home with a set of crows feet after I asked him if he had any that day So if you want to bring it back we can redo it and torque the lines down properly lol.

This is what a crowsfoot looks like. You stick your torque wrench in it off to the side.

Still - thats $75 and you got to have them balanced/shimmed and pop tested locally Seems ok.

How about you come down here and visit slacker !!!! If I can decide to do the mods - we have a bit to do !!!! 50/50 at the moment on that decision

or snap-on has some nice crowsfoot tools...i have been thinking about some injectors from jaime also..as you see you can get up to 200h.p. ones for $400..don't think that price can be beat...and me personally would buy whole injectors and not just nozzles..but..everyone is different and know there own budget.so that turbo...would that be a good upgrade for me?i am running the stock hy35 still...what kind of max.boost p.s.i. will they make?another thing is will this turbo accept my down pipe without having to buy a hx40 pipe?cuz i have a 4"inch downpipe and when it gets to the frame it is 5" all the way back.another info is helpful:thumbup2:

--- Update to the previous post...

oh i forgot to add the the nut that needs to be torqued..where it tightens up at the head...is very critical...to tight and to lose can/will cause it to leak....per mopar

That is why I like my 12V!! No need for fancy tools. All six of mine were installed in an hour on a hot engine!!

so that turbo...would that be a good upgrade for me?i am running the stock hy35 still...what kind of max.boost p.s.i. will they make?another thing is will this turbo accept my down pipe without having to buy a hx40 pipe?cuz i have a 4"inch downpipe and when it gets to the frame it is 5" all the way back.another info is helpful:thumbup2:

As far as I know the Hx35 or the hybrid 35/40 are interchangeable with the HY. Only difference is the HY has the vband clamp and the HX35 is a direct bolt in and a couple extra bolts.

I don't think there is a big difference in fueling capabiltiy from what I have read between them - but for us HY people -> lower EGT's due to the exhaust housing. Max boost would really be 35-40psi. Maybe extra 5 psi over HY.

With my expertise that I have found, I can now install on a 24 valve in 1.50. I will addmit I did not wont this new found experince.lolAnd by the way christmas has come early for folks in central Tx., we now have a full service Cummins shop just twenty five minutes from the house. yeaaaaaa Where were these people a year ago.I found it going to the Freightliner shop.

You will need a different down pipe if you go to any turbo that has an hx40 style exh hsg. Not only is the mounting different but it is 4 inch right out of the turbo.

The HX35 and the hx35/40 hybrids don't have this though right ? So good to go ??

Or is there years specifics as well ??

--- Update to the previous post...

oh yeah .... W+F ....... what do you think about dumping the RV275's and going to +75 or +100HP (on a HX35).

Just didn't really seem to gain much or notice much from the RV275's.

John when I went from your 275 back to my DDP 50'S you could tell a big diff. I am not pushing ddp's but they are good inj. DDP 75's or 100's would be awsome with just the set up you have. Imho

yeah thanks - I have a sale pending on my RV275's Going to try the CPP +100 s ........ and with my methanol kit hoping should be good power when I push on it - but still ok mileage when I baby it. Now need to find a decent HX35 - keep your ears out

If it is an hx35 then no but if its a hx40 hybrid it will have the HX40 4 inch exh flange so there lies the need for a new down pipe. As far as injectors I would stay under the 90hp range with a stock sized turbo. I had a BD super B with BD 90's and could bury the 1600 egt gauge with that setup with a regular comp. To give an idea, Industrial injection only reccomends 90-100hp injectors for the silver 62 turbo I have when I talked to them before buying it a few years ago and it is a WAY bigger than stock turbo. Do you already have a H2O meth system installed on the rig? Personally I would never run a water meth systems unless the head was o-ringed.

I tighten my fuel lines with a 3/4 wrench. I tighten them hard. I then drive and retighten the ones that leak. You have to tighten those things pretty hard.

The last couple times I have done just this as the suggested torque was not enough to keep em from leaking on my 02.

Heck with my RV275's, Edge Comp on 5x5, straight pipe ex, BHAF, and HX35 I can tag the 1,400*F easy... 100 HP injectors are going to be extremely hard to control... If you capable of controlling every power level up to 5x5 then I'd say go up in injector size... Remember Edge you can turn down to control EGT temps. But injectors once there install you cannot turn them down all you can do is slow down...

ok

you fellas scared me back down to +75HP. I sent the guys an email to change over.

Remember I will be running h20 injection as well - so that should cool and extra 150-250 degrees.

Will keep you posted on numbers ................ gotta get me that HX now

How come - you said before but I don't get the reason.

As long as I remain under 400HP which I should be right at

(230 stock + 75inj + 120 edge + 30 WMI) * 0.85 [15% driveline loss] ........ => 387 HP

I mean all its doing is adding vapour into the combustion cylinder - which gives more pressure -> but reduces cylinder temperatures as well as EGT temps.

If I was breaking 450-500 I could see the need for o-ringed head and ARP studs .............

or is there more to it ?

You answered your own question. Its all in the cylinder pressure it creates which will reduce the life of the head gasket regardless of egt or hp levels. I have seen wmi take out fire rings and o-ringed gaskets in extreme situations where they upped the jet size for dyno runs or pextra performance.

Cool. I assumed that the pressure really was converted to the extra HP - so essentially as long as you don't go over that 450 ish mark - then should be ok. I am pretty much planning on running straight water - to reduce EGT's and pick up 30HP. I am sure a couple of times I will run some methanol for fun ....... but nothing too heavy .................maybe 30% (straight windhield washer).

I love that John cannot leave well enough alone. He won't be happy till that enormous trailer does 70 over mountain passes. I wish I could do that with my truck. He is our own very r&d guy and we are better for it. Keep up the detailed research John. I for one hope you pass me on the hills soon!I have had 75's and 100's and if you want more power the 100's are great. The only thing you will need is a bigger turbo. You have an hx-35 so all you need is the bigger turbo for twins and you won't have to worry about egt's. Let me know when you are ready for that. I have an extra big turbo laying around...
