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. :( :(

So is the Fast intake the better one or is the ported LS3 the way to go? Sorry I might be missing something or I'm an idiot

the FAST looks like it makes a couple more hp, but for the money the ported

Im lost as hell

Looking at the top graph, it really doesnt make a whole lot of difference, no matter what you get. as far as general driving goes, its pretty much the same numbers all the way across, except for the two spots where it peaks up about 20-30HP more, which are at around 3800 and 5200RPM.
Then from 5200 on, its stays about 15 HP over.

Maybe I dont understand what is going on here, but i dont see the big improvement, or where it would really be noticed unless you are racing the car.

granted i know more about 4x4s than I do sports/performance/muscle car motor building, so it probably should confuse me.
Now if yall wanna talk about gears and lockers... im there

Looks to me that for $500 more you get 15hp+ over the ported LS3. Thats the difference of going stock vs. intalling a quality CAI. You damn near paid that much for one, right? Hell tunes are costing you close to that for the same results measly 15hp+, no? What's $500 more for the same power increase over a ported LS3? FAST 102R FTW!

I think you might be reading the graph incorrectly. The lower number is the stock intake, the higher numbers is the ported LS3 & out of the box FAST
