780hp/1800tq??

[RMalone]

No kidding MattyMac? With TST on 7,7 no load and wot I can see 1450egt no problem if the ambient temp is above 60deg. Just for hoots I put the TST on 9,9, temps in the high 80's, and saw 1750egt so fast I had to change my diaper. I have a spa guage and the numbers I claim are from the spa memory, supposedly the spa has a very fast thermocoupler so I may be seeing a real high "spike" in temps before serious boost cools things back off. Still, I can maintain 1400 under wot (tst 7,7) if its warm outside. I don't run pressure and doing so might help egt.



But... if I had twins and saw 1300egt w/TST on 3,3 I would be p****d off!!

I think that guy could make the HP but not the torque. I did 760 HP today, single turbo, couple boxes, small inj. , water/meth, and nos. This as on a dynojet too. My max power was on level 5 out of 9 on the TST.

 

[CTDFreak]

well... what was your torque with the 760?

 

[lmills]

Have you not been to the track with that combo? Cause the 1/4 times do not add up to 760.

... ... . Here we go... :-{}

I threw the water/meth and nos on two days ago. I dynoed yesterday. The best time was 12. 49 on all motor and the truck is a two wheel drive quad cab short bed. I have 12. 5-28-16 tire that are on 10 inch wheels that stick out. I had to grind the caliper a hair to get them to fit. With 13 pounds of air, the truck takes off hard, then hit second and imediately locks the converter, spins the tires, and doesn't start to hook until the first part of third. When i have the nos on, i plan on hitting it after third and i should be in the 11's, ... but only once, they'll make me cage it and put a 5 piece seat belt in then. You know Imillis... ... i saw HVAC put down 788 hp in MM and that night only run in the 13's. He just couldn't hook. Correct me if I am off, B. Pine. Just because a truck has HP, doesen't meen it is fast. The tach wouldn't stick so i never got a torque readding.

My next question would be what was the correction factor?



Heck, Brett Williams of I. I. did 688hp, but it was at 20% correction factor...



As far as I knew the absolutle highest 3rd gen was 690-something by Piers himself



If you truely broke 760 with less then say... 5% CF, then you are among the elite few! Congrats!

Hah!

Well it looks as though I got something started! For all you gearheads out there... I was on the phone with Schied and ATS yesterday and the consensus is that the GEN3 fuel system can't keep up with the fuel requirements I have with the 80hp injectors. The pump is the problem. Fuel pressure drops in the rail as the injectors requirements increase under full throttle. I DO NOT HAVE EGT ISSUES WHILE TOWING. All EGT's under 5/5 on the TST, and above are high and fuel just isn't getting to the motor. This is why the power loss. On a good note, it seems as though ATS is working on a secondary pump to fix the issue and it will be out around Christmas. You will need to run a FASS system(150 gpm) with it for it to work properly. Then maybe I will see what it will do on a Dyno.

 

[lmills]

Never once did anyone see me question if the hp has been done. If so, please quote it in context! I simply asked if you had run the truck at the track with the current set up. You all need to untwist your panties.



However correct me if I am wrong, but you did confirm what I asked. The 12. 50 pass was all motor. You haven't ran it with the NOS or water meth. That was all I asked.

 

[Reb.B]

Okay, here we go on answering a couple of questions. The uncorrected HP was 770. 4 HP. Corrected HP was 759. 8 hp. It was 10 in the morning and it was 45-55 degrees outside and i'm close to sea level so thats why they pulled the power off. The dyno is set for SAE. Its a dynojet dyno which is very hard for a turbo diesel to make power on because it doesn't load you. Here is some corrected results: 634 max power motor only, 666. 6 hp water meth, 759. 8 hp water, meth, and NOS. Max power on level 5/9. I lost 150 hp when i put the box on 7/9. This was the main purpose of dynoing, the time slip said the same thing, but i wanted to see if i was losing power or losing more tracion. I have Don M. s inj. Piers, i believe did over 700 (738 0r 768?)not sure though please don't quote me, on motor only but the truck didn't run the way he would have liked it too and it was on a load dyno. My engine is a calif. 235 engine with smaller pistons too. I'm running alot of NOS too, (110 thou. ) and i'm running a 50/50 mix on the water/meth.

Next problem is fuel pressure. I need a bigger pump #1 and i need to get more rail pressure and a dual feed. ATS is dual feeding fuel at 125 psi into the cp3 after 3/4 foot throttle. They were keeping the rail pressure at the desired level with medium sized inj. I think that after a little more turbo work and a little more NOS work and propper rail pressure at higher duration levels this truck is really going to scream. I'm running studs but stock gasket. I'm only seeing 62 psi boost on the single turbo, but i'm moving GOBS of CFM. I think that by going a little bigger on the exhaust housing i can still keep my stock head hasket.

 

[lmills]

sounds good. you have confirmed something that I have been discussing with a couple local members. it's time for us thrid genners to cause an uprise.

 

[JCleary]

Industrial Injection is also working on a pump.



The ATS is $2700 and requires you to install a 125psi pusher pump.



The II pump (so I've been told) does not need the additional pump, and will be much less expensive.

As well JohnIsaac has a working prototype mod-CP3 on his pulling truck...



LMills - you are right, I feel the CRD as the HP king is coming and coming strong!!

 

[Tomeygun]

I'm only seeing 62 psi boost on the single turbo, but i'm moving GOBS of CFM. I think that by going a little bigger on the exhaust housing i can still keep my stock head hasket.

Thats a heck of a single!! soo... umm... what kind of turbo?

(if you dont mind telling)

 

[Reb.B]

On the dynojet the common rail will win. This is my reasoning. The dynojet does not load. Our engine is a 3000 rpm engine with a 5000 rpm turbo. We have to get max air at 3000 rpm to get the highest HP. Okay, this is the same for all cummins b series engines. What make the common rail different from the rest is the ability to put in multiple shots of diesel in the same stroke, which in turn creates a better burn, which in turn causes more expansion of gases, (ie. more powerfull exhaust at lower rpm) and spools the turbo faster than the older engines. This is why a common rail can run a larger turbo on the street easier and this is why a common rail can twist a fast turbo in half even though it is waste gated at 40 psi. The next reason is duration and if we can over come the rail pressure problem, then the HP numbers will jump like crazy. I am also thinking that there are cam some issues as well, Piers has a really nice common rail cam. I'm planning on sticking one in soon(mainly for the huge increase in fuel mileage and torque), but i want to get as much power as i can on the stock long block, then look at other outlets for making power.

 

[Reb.B]

Hey Tomeygun, I'll be over in Pahrump for MM'06, that will give you an excuse to roll on over and see what a little single will do. Thats if i still have it on. I still think that this 2200 cfm turbo that is arriving here in a couple of days will make some awesome power as a single. I know it will work as a twin, but i want to keep the boost down, ... more testing i guess.

2200 cfm single? on a 3rd gen? thats got to be quite a ride when it spools - So thats like bolting up a HT4C as my single? :--)





"Wait,wait,wait,wait,wait,wait,wait - HOOOLLLLLLDDDDDDDD OOOOONNNNNN"

 

[Reb.B]

Well my turbo now is flowing less cfm but with a little bit of thought i think it can get the 2200 cfm single to spool before 3000 rpm. all i care about is getting more than 1500 cfm before 3000 rpm. Dyno queens are very rarely street friendly. The truck drives very nice now, we'll see when it gets closer to May.

 

[michaelRitz]

You guys get all this worked out so within the next year or 2 I will be able to put the perfect setup on my truck, WAIT there probably may never be a perfect setup but a lot of really good ones, trial and error I suppose, What a blast it is to be so enthuised in such a great thing like a 5. 9L Cummins in a Dodge

 

[michaelRitz]

Oh, bye the way lmills did I ever mention I am as inpatient as anybody could possible be HA HA HA
