Here is the info i was takking about. Keep in mind there was no tuning involved what so ever! Just swapping manifolds.

 

 

 

We did some testing on a 2007 Silverado 5.3L engine. Its a new body style truck that comes OEM with the 90mm throttle body and what looks exactly like a TBSS intake manifold which we were swapping to a FAST LSXRT truck intake manifold.

 

The truck tested was 100%stock, and there was no tuning done during testing, the OEM 90mm DBW throttle body was used on the 102mm intake.

 

The intakes were fairly close below 4500RPM, but after 4500 RPM is where the FAST LSXRT started to take off!!

 

Here are the power gains.

 

4500 +3.5rwhp

5000 +17.3rwhp

5500 +20.5rwhp

6000 +19.8rwhp

That was a previous test by someone else. Art is packing more then a 5.3l. And provide the results of that test were not skewed in anyway, art should see more hp with the cubic inches, compression and head flow

okay i received the manifold yesterday. Going to sand down and remove the vacuum tube and tb cable mounts as i will not use them and make it look a little nicer. I will be painting it satin black. Stay tuned.....
