Thinking about twins...

[KLockliear]

Scott, that depends on what we can come up with for the next level. If we can do it with a single, we will. Mainly due to cost and complexity. We will not go to twins unless we have to.

 

[Jim Fulmer]

It just depends on what you want and can afford when it comes to power, or what you can build, in my case both!

See, it's threads like this that have me worried about a big single:

I'm not looking for HUGE power here just a lot of power in a reliable and somewhat foolproof (EGT wise anyhow) daily driver.

Guess it depends on what single you are talking about.

 

[Fred Swanson]

Greg, a Dog! That's a low blow.

With 500 HP, the DD single I'm running spools very quick, and EGT's are not out of control, actually they are very usable for empty driving and heavy towing.



Now when more power is available, we'll see where that goes.

SRadke-The KSB can be used as the smaller turbo in a twin setup without any mods. However the tubing, wastegate, polishing, ceramic coating, oil lines, trial and error will require some mods.

 

[Gypsyman]

Does anyone know the specifics of the KSB-1-2-03. Turbine and comp wheel size, exhaust housing size, what does it spool like in a towing situation, what hp will it support? I tow more than half of the time and a lag pig will be more than just an occasional PITA.

I know that the TST and VA 3. 2 duration on higher settings can blow the bigger huffers apart. Also I havent heard of these boxes and good injectors that a single can fully support, (Or the TST alone on 9/9 for that matter).





So what about us guys who want to run 400-500hp with a big single because of the cost of twins and still have decent spool up, and manage EGT's enough for towing? What are our options?



Ive been waiting for the best turbo to match with my TST but with all the horror stories about the bigger turbos and these chips I have been wondering about a twin set up as well.



Alot of performance manufacturers have been claiming decent spooling singles good EGT control on 500+ HP but no one on this board really has talked about it. Ive got my money right now but am just waiting for some good feedback, Keith, or anyone for that matter can you help us out here?

I have posted a couple of times on this forum about running a big single turbo on an 03'. I run the EEP single turbo and have made 540 hp on 2 different dyno's. One dyno was here in Michigan and the other was at Muncie. I have no durability issues and the lag is very minimal. I believe this turbo is much more reliable than the DD jammer for the 03'. I think the DD turbo is good for about 450 hp but that is the limitation. I have seen a couple of failures at hp level above that.

 

[Gypsyman]

Where can we find info on the EEP singles?



-Richard

 

[silver03]

Call Enterprise Engines or go to their web site http://www.enterpriseengine.com/

 

[Gypsyman]

Thank you sir...

 

[mattymac]

The EEP turbo is not a direct bolt on! Also the turbo that silver 03 is running isnt on their website.

 

[KLockliear]

mattymac We do not suggest using the Jammer (or any turbo we currently sell) with the VA or TST box. With our injectors and the TTPM (up to 500hp), they work very well, but the aggressiveness of those duration boxes seem to kill most turbo's.

 

[mattymac]

what can be said about the timing issue and EGT's? I love the extra timing in my TST, if it wasnt for it this box would be almost unusable in my book. VA has never had a reputation for having an aggressive box, what is making these duration boxes kill turbos (bigger ones esspecially)? does anyone know? seems like if a duration box can smoke a turbo why shouldnt a pressure box with a hot set of injectors. I also understand its not the power that hurts parts its the delivery of it so what are the characteristics of these duration boxes that are hurting parts? The TST for the D-max is almost the same box as our cummins box and I understand it holds awesome. Also keith, isnt the TTPM an EZ with sligtly diffrent programing? So will it and the injectors work with a 600?

 

[Gypsyman]

Keith,

Would the KSB-1-2-03 be ok with your DD2's? I don't want to lose my exhaust brake or have to buy another one if I can help it. BTW, I'm close to the Ogden dealer. Are the DD2's exchange or would I have to leave the truck with them while the injectors are reworked? I'll assume that the turbo will have to be in place before the 2's go in due to egt's. Am I correct in this assumption?



-Richard

 

[KLockliear]

Mattymac, it's how aggressively they bring the power on. The injectors/TTPM is much smoother. All the parts (boxes and injectors) are different for the 600.



Gypsyman, not sure on the KSB1... never used or tested one. With the 3G trucks, we modify your injectors on a same-day turn around. This ensures you get back the same mileage/condition set that you sent in.

 

[Gypsyman]

So I take it they don't do installs in the Ogden shop. How about the Vegas shop?

Can it keep up with the TST? I doubt it.



Keith, You also stated " it depends on what single were talking about", Do you know of anyone who has a tested or running a nicely mannered fast spooling street single that can hold to the TST? I dont want a war here keith or anyone else!!! But keith you know more on the inside and are able to talk to or hear more about this stuff than most people on this board and its awesome that you share it with us here, we are truly greatful. The reason most of us are using the TST and VA boxes is because they make the most power dollar for dollar and you stated you dont like running twins because of the price and complexity issue and you wont run them if you dont need them (why would you), the same goes for a mild chip EZ, TTPM, and so on along with an awesome set of injectors, then a turbo, then add in the price for a good trans set up for the power, its more money than just a TST or VA trans and turbo set up with more adjustability.

 

[KLockliear]

Gypsyman, I answered your other thread that Ken can do installs in Ogden. We are not doing any installs at this time in Vegas.



Mattymac - for a given power level, all the "supporting equipment" will be the same. This means that if your truck makes 450hp, regardless if it's done with a TST box or a rail pressure box and injectors, it will still need the same support equipment (gauges, exhaust, airbox, bigger turbo, fuel pusher kit, clutch or trans work).



That being the case, if you are truely looking to make the kind of power that requires all those other things, then the OPTION to do it in a way that doesn't kill turbo's is just that - the option. You can choose to do it another way, granted a little cheaper, but you will have problems with what is out there to support it.



We simply say that our turbo won't work with the TST box or VA box. We don't sell either, and don't feel that we should R&D them to offer stuff to make those boxes be reliable. If you want 450hp or 500hp, we can and have been selling products to do that for some time on the 3G trucks. If you choose to go another route, it's certainly your choice - but that choice forces other choices as well, the turbo being one of them.



We do have another turbo being built that should handle the TST and injectors pretty well, but it will be for the 500+hp range. It is not intended for 300-500hp trucks. It's a larger single, with good spool characteristics, very strong and dual ceramic ball bearings. It is on the horizon, but not here yet. The casting process takes quite some time.



Hope that helps.
