12'SROCK Posted August 20, 2013 Author Report Share Posted August 20, 2013 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 Quote Link to comment Share on other sites More sharing options...
Downeast Johnny Posted August 21, 2013 Report Share Posted August 21, 2013 Thanks for taking the effort and sharing the results. Gotta wonder what a tune would do for it, especially below 4500. Going to experiment some more with it? Quote Link to comment Share on other sites More sharing options...
shadowsniper3006 Posted August 21, 2013 Report Share Posted August 21, 2013 (edited) 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 Sent from my SAMSUNG-SGH-I747 using Tapatalk 2 Edited August 21, 2013 by shadowsniper3006 (see edit history) Quote Link to comment Share on other sites More sharing options...

12'SROCK Posted August 28, 2013 Author Report Share Posted August 28, 2013 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.

12'SROCK Posted September 1, 2013 Author Report Share Posted September 1, 2013 Finished up the truck today. Drives great!! No surging issues at all. My tuner ks a little busy right now but as soon as he frees up she will be put back on the rollers. Be patient. Quote Link to comment Share on other sites More sharing options...
