First I tried to find another place to post this but I could not find one but since I am going boosted I figured this is a good place to do it. I am doing a swap in my '01 sierra the typical 6.0 4L80, I am going to use the truck for my tow vehicle. I am going to run a Texas Speed stage IV high lift came, Procharger D1sc, long tube headers full exhaust, built trans with converter, and rear gear change from 3.42 to possible 4.10/4.11, with air ride in rear for towing and possible meth injection. Wanting to find out from whom ever what would be a good intake to run, I have seen a sheet metal intake from Summit that is nice, I am running a new fuel system with the set up and like the intake I am talking about above is clean and comes in polished or black, comes with rails and a 102mm throttle body. If anyone has a thought let me know, I do want to emphasize this truck is going to be a tow vehicle so I will need horsepower and torque, let me know thanks.

 

Stock intake.

Stock intake.

 

 

X3 on the stock tbss/truck intake, best bang for buck

 

 

Dont flow better than stock and lose torque, require a belt re-route and fuel system mods.

Its like spending money just because you wanted to, but not getting anything in return.

The truck intakes are incredible.

 

What is the biggest throttle body I can run with a stock truck or tbss intake?

 

I honestly don't know but it really does not matter so much on a turbo or procharger application. It would matter far more on a supercharger that is trying to suck in air.

Stock throttle bodies can make 800-900+whp.
