Does anyone in here have twin turbos? I have a 2012 Denali HD that I'm thinking of doing this to, and I'm curious to see y'all's setups, and any helpful info before I decide. Thanks!

 

We have done alot of twin turbo kits for the LML duramax trucks. What other modifications do you have to the truck that will support the twins?

 

I don't have any mods yet, but I'm in the market for it.

 

Any suggestions? I'm all ears

 

Carefull, that's the best way to make a small fortune...start with a large one and mod your truck. Do a lot of homework before you start and have fun.

 

I would say look into an s475 over stock kit. With stock fuel, a built trans, converted 10mm CSP3 pump, and lift pump you should be around 650 RWHP.

 

I will look into that for sure! Thank you!

dump the CP4 and replace it with the proven CP3. Also CP4 dose not have much capacity over its currant output.

built transmission is a must with anything over about 90ish HP over stock if you want it to live

 

A Cp3 only has capacity for 600 RWHP, a Cp4 has a capacity for about 550 RWHP although the Cp3 is known for being slightly more reliable.
If you are going to run twin turbo's I would think the 10mm Cp3 would be the best fit, since you have room to grow (capacity supports about 750 RWHP).

The LML transmission is much more stout than any of the previous models. Realistically running them at 550 RWHP (which is 150 RWHP over stock) is about as far as you will want to take a daily driver.

 

Some great info ^ thank you!
