Yea, but what if all im really planning to do is just TST, maybe stacked with TS MP8 and some injectors, nothing insane. Thats about it, I really dont need a turbo that can hadle 600hp( considering im just trying to be in the hi 12s/ low 13s. I just want the fastest spool up SINGLE TURBO. The twins are just too expensive, If I didnt have to build the trans, then the TT setup would be fine. But trans plus TT is more than $8k.

 

It depends on what you are going to do with your truck. I spent less than $2k on my tranny and plan to be 500-550hp and in the 13s, but I will never launch at more than a few psi and I will never hook to a sled either. If you don't expect the tranny to have to hold 500-600hp while power braking, you don't need to spend all that money on billet parts. You can have 600hp and stomp it from idle and a TC/VB set up will hold fine, because you already have the parts moving by the time you get into full power.
Don't get me wrong - I'm trying to figure out how to upgrade without spending the money on twins as well, I;m just saying that you don't have to spend $8k.

 

good, then whats the fastest spooling SINGLE TURBO that can handle most power? or how much ever power is hi 12s/low 13s

 

If your planning on running hi 12's/low13s, Cheap shouldn't be in the same sentence. IMO if you plan on getting into the 12s by saving money on the tranny/turbo then you will end up spending more money in the long run fixing parts. If you want the FASTEST spool up single turbo leave your stocker on

 

Listen to Luken and others. Any vehicle in the 12's has some power... a 7000lb + truck in the 12's is crazy power. An old timer used to tell me the only substitute for cubic inches is rectangular dollars... It cost's money to go fast... don't fool yourself...

 

What you dont understand is low 13's and hi 12's is insane, youll need 600HP or more, you said you wernt looking for something that can support 600, but if you want 12's your gona need it.

 

You guys with twins, is it hard to set them up and dial them in? Do you need any special equipment? I am looking for the latest and greatest for a twin set up and would appreciate any recommendations.
I hope for once I am approaching this in the right direction (tranny first), I usually do the power thing first and break lotsa things. lol.

Just so you all know I'm a convert------I use to be a power stroke guy but sold that big piece of 6.0 and here I am. (Sure strange getting use to the lower rpm power)

Thanks to all!

 

Welcome.... just keep reading... and asking questions...This is a great place to learn ALOT of info...

 

so you're telling me my STOCK turbo will spool faster then any single turbo but wont be able to handle the power of a bigger single like PHAT SHAFT 64, HTB2.....etc? The last thing I want is LAG. So my turbo can handle what, low 13s?

 

I was jokin about the stock turbo. The stock turbo has no lag but it will not cool enough. If you get a single big enough to handle 550+ you will have lag.

 

Not for any lenght of time, low 14's would be pushing it.

 

Go for the relentless diesel twins. Those things are awesome! Check out thier website for videos of his customers truck running 11.80.

 

what are you talkin about? Our turbos are good for about low 13s. TST chip with level 6 (highest level for our turbos and NOT trans) can do mid/high 13s

 

I highly doubt a stock turbo will put a truck in the low 13s. If it were possible your EGT's would be through the roof...

 

Hey Viking just for curiousity how old are you?

Most of the replys here are from people who do not have direct twins experience, they just read posts about twins and instantly decide they are the best for everybody.

You need to be realistic about what you want. You want a 12 sec 7,000lb diesel truck that will have 500hp and drive like a stock truck. Aint gonna happen.

It takes alot to get into the high 12's...ESPECIALLY when you want to go cheap on your tranny and not going to launch it. The difference between launching will turn your 12 second truck into a 14 second truck maybe 15's. It take a long time for any bigger turbo to spool. Since 3rd gens are the slowest and heaviest it will take you 615+ HP to be in the 12's.

Now lets think about all the $$$ it takes to be in the 12's and how much twins cost and work effeciently on a 12 second 600 HP rig. I had B1/B2 twins and needed to spend nearly an extra $2,000 for O-ringing and ARP studding my head to support the amount of extra boost from the twins.

Like people said before if you have the $$$ the definetly go with twins but im guessing you dont since I remember someone wanting to go cheap on the trans, I could be mistaken though. From reading you want and then converting it into reality I think you would be happy with a turbo from Industrial Injection they and a New School Turbo and work perfet for a high HP truck that is still a daily driver and can rip it up on the weekends and bring you high 13's with simple, basic mods. I mean if you want to get wicked with this truck youre gonna spend lots od $$$ getting Billet tranny parts, injectors, stacked boxes, FASS, CP3 mods, ect.

Most people the are probably telling you twins are what you need probably have no experience with II's SPS turbos or any newer then HX40 turbos. I know who's a hard hitter here on this board and most of them havent replyed here.

So I voted New School Big Single unless you have a 10K budget to get serious with this diesel drag racing

I could go on and on.

There is a huge difference between building a 500hp truck vs a 600HP truck.
