Engine Dyno Testing LS3 Intakes INSIDE!! LS3 vs Ported vs FAST

After swapping intakes for the last 3 days we finally have some data for you guys. These tests were run 2 different ways, once with a maf in place & the test I'm posting which was speed density. The speed density showed power gains that the 85mm MAF was holding back. As a result I'm only posting the Speed density results. If your getting a upgraded intake you really should consider a 100mm maf or speed density tune to see decent power gains.

Here's a few pics of the intake testing:



Results:


Differences:



We're currently offering the FAST LS3 intakes for under $800 shipped to your door. The LS3 intake porting is right about $300.

For the 2010 guys these results should be pretty close to what they'll see. Using the speed density best simulates the large MAF the LS3 cars ship with!!!

Engine was a stock head LS3 with TSP 233/240 112+2 camshaft.

you guys do an amazin job...do you think your 80hp cam would still be effective with stock manifold, catless downpipes into the stock 2,5 inch catback? Or do i really need longtubes and 3 inch exhaust? For a supercharged car i understand ; but just a big cam set like yours?
Thank you!

We didn't have the best luck with our ported one, so we're going to try again on a car. The first ported one lost power & I tried it two different times. :( :(
