I thought gm hitech or someone else did some intake testing and they found the truck intake better, even better than the LSXrt (new fast truck intake)

 

Great! I'll have to find that.

I have tested the L76 car intake vs the L92 truck intake. I can get the graph tommorow.

 

*waits*

 

I meant to say monday, ive been on vacation for a week and forgot what day it was..... Wait one more day...

EDIT: I totally forgot to get the info, first day back, busy as could be.

 

Im emailing myself a reminder.......I didnt even give this a thought this week.

 

I remembered them , I have two different LS3 setups that were tested. I just have a few errands to run and Ill scan & post them later tonight.

The L92 is a little better, not by a ton though.

A 6.2L with 1 3/4" headers into a single 3" and a camshaft. This one made 8-10 Flywheel horepower from 4500-5700

 

Nope, the FAST is much better than any GM intake. Spectacle just tested an TBSS vs a FAST LSXRT and the FAST beat it by 20rwhp on a STOCK 5.3L. So it should be worth 30rwhp over a regular "Big Ugly" intake.

 

I know this is old by a year, but is there any validity to the above statement? Anybody test the L92 FAST intake?
