370's and #10!

[Wirenut]

Yesterday I installed my #10 TST plate and today I installed my 370 injectors! ..... ... ... . ... ... . well, thats about all I can say. Of course it started raining while I was putting the injectors today to make the roads wet for my test drive... . I've never seen a dually all over the road like that... ...

 

[Wirenut]

Well I already know what my next item purchase is... . Souh Bend clutch, definitely. It slips so bad that its not even funny.

 

[GOTSOOT]

OH YEA!!!

Wirenut: thanx for the reply on the Cell phone,btw how soon do you think that you will be getting your NEW clutch,I need one also with just a #-11 and 370`s can`t imagine what a #-10 must be like?What part # was your 370`s?Got any idea what kind of hp you might be putting out now? thanx

 

[Wirenut]

Im not sure what the part number is on the 370's. Joseph Donnelly is the man there. I would figure on being somewhere between 350-400hp. Im not getting it all to the ground yet though with that stinkin stock clutch I'll have to find a way to make some more money to get a south bend clutch... so who knows how long it will take me, hopefully within the next month.

Can't wait

Man, I can't wait now.



Wirenut, what turbo are you runing ? and what's the EGT's like ?

 

[gitchesum]

Fun ain't it.

Mom, even drove it to work the other day. Made a point to call me long distance to tell me how much fun it was driving a big ol truck that moved that quick. She even hinted at wanting one

Pop's in trouble now. especially since he's a die-hard Ford diesel guy.

 

[Wirenut]

Im running the stock 12cm turbo because I couldn't get the housing off to replace with the larger one I have for now,... Hx-40 is on the wish list. If I go through the gears gettin on it, Im at 1200° pre-turbo by the time I shift out of 4th. I have the plate slid more than half way back.

 

[BigBadDodge]

I have my plate slid all the way forward along with the AFC Housing, stock turbo, and I am seeing 1600 plus post turbo in fourth gear hammered with 42ftlbs boost. I am just trying to determine if I should wait for a new turbo before installing the 370's.



Thanks

Looks like it is time for a ported cylinder head and a HX-40 turbo for the BigBadDodge



Don~

 

[BigBadDodge]

Don, I am already considering a larger turbo, kinda leaning toward a h2e though with all the Hx-40's I have heard about breaking shafts. The wife almost slapped me when I told her what a turbo cost, can't imagine what she would do when I exsplained the price to get the head ported and polished. Speaking of that, what kind of HP gains can that do for one ?



Scott,

Head porting is just like changing camshafts. It gives you no horsepower gain, but allows more oxygen in the chamber and lowers EGT. Thus allowing you to add more fuel and make more power.



Did you say 1600° post turbo? You need to put the probe pre turbo. You might have some kind of record there!

The HX-40 is still a good little turbo and can last with care. The hybrid hx-40 with the smaller housings is not gonna last for too long. Mine went about 1500 miles.



The standard HX40 with a 16 housing can last a good long time.



Porting the head does not add much HP. I think Joe D. said he got about 10HP from it. The lower EGT's was my main reason to do it. I wanted to lower the compression with the thicker head gasket too.

I dont have my ported head on yet. Hopefully I can hook up with Cord (the guy who brought it back for me from Joe Donnelly) and get it installed in the next few days.



You might get as much as 35 HP from both the turbo and the ported head and way lower EGT's.

OOP's

Chris, sorry no record here, I meant pre. My bad



Don, hope all goes well with head install. If you don't mined me asking how much did it set you back ? You can PM me if you can't say in this forum.



So how high can we go in HP with the HX-40 and a 16cm housing ? I don't know about you all but I just want to break 500HP

 

[Don M]

Not really sure how high. Prolly closer to 475 with the 40/16.

The 18. 5 would make a little more power but would lag alot.



Joe got to 508HP with close to what you got now plus the ported head, 370's, and hx40 turbo.



Joe or Piers can get ya to plus or minus 500HP from where you are now.



I purchased a new head, new valves, springs, retainers, etc from Cummins via Joe. The porting was the cheapest part. The castings are spendy, but you have a head on your truck now you can use a avoid the extra cost of buying one. I just bought one new to avoid as much downtime as possible.

Way back in the old days, I had around 400 hp with a torque plate, HX35, and 18. 5 cm2 housing (not lower egt than the 16 but did help keep total boost down a bit for the health of the little -35. ) Poarting the head didn't help much if at all on hp but cut egt a couple hundred degrees. I added the 370 injectors and it felt like maybe 440 hp. This is when I spent days--literally--with the Cummins catalog typing in engine serial numbers until I stumbled onto a couple 370 marine engines. I then gave the numbers to Piers and he could use his Bosch connections to get the injectors from Germany. So, our next project was the HX40 and I told him I wanted a little bigger on both ends, and an 18 exhaust housing with outlet for 4" pipe for airflow, compared to the HX35. I got the second -40 and second downpipe, handmade by Piers--he put the first stuff on his truck what kinda friend is that Then I went to the Dynojet and got 510. 7 hp.

Moral of the story is that airflow will give a lot of hp if you have been bottled up for the fueling level you have. If you are pacing the fuel and air increases, you might think the expensive air improvements didn't help. Air+Fuel=Power. Yep, like I said in TDR23



Those new fire nozzles from Lawrence should be just the thing. They dumped so much fuel at Pahrump, it couldn't all burn in the cold air (I didn't have the chance to fully warm up the truck before dyno'ing). Given some temperature, they may be even better than the prototypes I used for 609 hp last March.



The airflow work you guys are doing now won't be "wasted. " More fuel will come along

 

[HoleshotHolset]

Fire nozzles... . very interesting.

Looks like the 370's are out and this is what I'll be buying once they become readily available.

Fire Nozzels

Joe,



What are these Fire Nozzels ? Not familar with them, are they real new ? in testing phase ? How much HP will the provide over stock injectors or over the 370's ? who makes them ? Quality ? Price ? when will they be availible ?



Sorry for all the questions, but I am going to be in the market for Injectors after the Turbo and want to soak up as much info on them as possible.



Scott

 

[Joseph Donnelly]

fire nozzles is the name I gave the latest prototype high horsepower injectors from Diesel Dynamics. I have another type of prototypes also to test. Time and the Dynojet will tell.

 

[Wirenut]

BigBadDodge, if your seeing 1600 after the turbo, isn't something gonna break!? I though 1200 pre turbo is what you didnt want to go past? I'd be really scared if I saw that number on my gauge. If it's ok to see those numbers, then lets slide that plate a little more

 

[Don M]

fire nozzles hmmmm

I would love to get my hands on some extrude honed 370's.

Stage 4 for 12 valves from DD would be great.
