Tbss intake with procharger?
Okay guys I’ve tried to search for a thread where someone has switched from a stock gen3 truck intake to a tbss/nnbs intake while using boost. The only thread I’ve found is where one guy with a turbo was thinking about it and everyone said it wasn’t worth the money. Currently I have everything I need for the swap besides an x link, evap solenoid, and tb coolant bypass. I’m dropping the pulley size down on my procharger from a 4.0 to a 3.7 and was wondering if the intake swap would justify the cost of the remaining components. Has anyone with a procharger or turbo done this swap and if so what were the results?

Well, just thinking logically,
On a NA setup it's a proven 20hp at the wheels, at the least.
On a boosted motor, I can't see why it wouldn't do just as well if not better.
It's a proven, cheap swap, despite the cost of the xlink. Definitely more bang for your buck over the LSX-RT manifold or a Holley Hi-Ram.

It would be an improvement. But would it be worth bothering with when you can get a lot more with a pulley swap......that is the thing everyone brings up. If you are still in the building stage then yes go ahead and get it. But if it is already running I would not bother....

Thanks for the help guys. Yeah I can’t see how it wouldn’t be beneficial since restriction is reduced. If anyone else has any real world numbers and times they’d like to throw in I’d appreciate it. I’m going to throw it on and see how much she makes with it and the smaller pulley, should be around 13-14 psi.

The difference that it makes will be at part throttle and no boost conditions throttle response. The generic response of "not worth it for a boosted application" would only be true if you were always in boost. Like for example a stationary generator that runs at full throttle any time it runs. If you appreciate better throttle response, go for it. If you only care about full throttle horsepower, don't waste your money. The TBSS manifold will improve both, but the noticable difference will be in everyday driving.

I have to disagree. There are gains to be had while in boost too.
The largest gains from this NA are when the engine starts to pull vacuum after the 78mm can no longer keep up - that much I will admit. So boost does its part to help negate that. However, the torque gains over the standard 78mm when both are at say 100kpa are kind of staggering. Those same gains will translate with a blown engine. The path the air takes is still important... but because its compressed doesnt mean you no longer have benefits from scavenge or velocity. the 87mm intake is a more efficient design with better intake runners.
