20 Ls cathedral intakes tested! Not sure if this has been posted already but hotrod just did this test. But most importantly they included all versions of a FAST and the MSD. Looks like the fast is still the best game in town until msd gets their qc and throttle bracket under control. Then after that it's a crap shoot

I was about to post this.
Richard Holdener does a thorough job testing. But the carb-style intakes really need a lot more overlap to work better. But all the plastic intakes have a cam that uses the 231/247 113 cam... which would be a good blower cam. Huge difference between the LS1/6 and the FAST 102. Damn.

Verdad Gallardo Other thing to note: that's not an ideal cathedral port cam. But that's sort of the point. You can throw almost anything into a cathedral port motor and it'll make power.
Those heads were AFR 230s... With a 230s duration cam and a FAST... damn near 600HP on a 370.

Gee let's see, $550 for an old used LS6 or $250 more for a FAST/MSD that crushes it on setups from mild to wild......
Who woulda thunk that piece of plastic would be worth $100 more than a full set of 243 heads in 2015.

great article, I like that it also showed average hp/tq from 3000-7000 rpm. gives a good apples to Apple's comparison as to how different intakes make power under the curve. I was surprised to see that the old fast 78 was within 3-4 average hp/tq of the new msd, even though it was a difference of 20 hp up top.

I was pleasantly surprised by how well that hideous TBSS intake did. If I was going to use a factory intake, the TBSS is the one I'd get.
Honestly, I'm absolutely not surprised by how well the fast intakes did. There's a reason everyone uses them.
