TT Setup Help

[SRT10KLLR]

Something you probably have no idea about or overlooked, those stock manifolds are going to cause a great amount of heat.
I'm not talking about a little wrap here and there, I'm talking when it's 100deg outside, you can say goodbye to any wiring, plastic, electronics that are within 8 inches of the manifold!!!!
Your underhood temps will be so damn hot you won't believe it!!

Trust me on this one, been there done that. I'm only warning you once lol, twin turbo setups using stock manifolds produce a sh!t load of heat!!!
For some reason, using a single setup like I offer is fine, going twins, yikes!
So wrap wrap wrap all the parts around the manifolds as well as the manifolds.

-2.5" is fine for the hotside, there won't be much hot side, just a small length of 2.5" going from the manifold to the turbo.
-with that engine, .96 a/r is fine, so is .81. I use .96 on my 408 with low compression and twins, using stock manifolds.
-I run twin 38's and it's just fine, it wouldn't hurt to go 40mm or 60mm, but my 38's work fine and hold boost and it's very steady.
-bov, just get a 50+mm bov, single before the throttle is fine.
-no, the turbos are fine ,the engine needs them! i ran T60's for a while, the truck is stronger with T76's.

good luck,

Thanks, I got almost the same advice from another member so I know it is sound advice.

Here is what he wrote "hotside piping 2" in and 3" downpipes
coldside 2.5" into a single 3" will be fine
wastegates small ones will be fine, 38mm or so whatever you want
BOV JGS 50mm or 60mm, or Tial Q
Turbine housings i would go with the .81 so you only have to buy 1. The .96 would be too laggy..Even with the .81's its gonna be laggy but should make 7-800whp on pretty low boost numbers. yes the 2" would be perfect,will help with spool alot. you can form them to the T4 or get whatever you need to for a cone or transition readily. Merging the 2 3" DPs into a single 4" would be ideal unless you can fit a 5", then that would be even better!

With that big of a turbine wheel you could get away with the smallest housings availible and not have back pressure issues. With the .70 housing,(which i beleive is divided even) would net 5psi probably around 3400, the .81 would be around 3800 in my guesstimation."

i guess i didnt awnser your questions correctly last time u called me so why dont u do it again ........ 76mm will make alot of power itself... twins will make twice your goal .... I have been slammed the last few days but i have a couple of hours driving tomorrow and i will call ya

I have been on the road myself but got back in last night. Call me anytime as I don't want to bug you at a bad time.

Twins are cool.

Yeh, I have your single kit which is what I was going to use but not I have to make it a twin kit, lol.


Here are some pics of the GT-76 I have for the Silverado and the GT-76 I took of the Hemi(Black coated turbine housing - Left).




I had to replace the turbo in the Hemi so I got a Comp 80/79(Right).






I already talked to the guy who made the custom headers for the Hemi and he will be making me the twin piping soon.

For now I just installed a Nitrous Outlet plate kit so that should hold me over for a little while, lol.
