Performance Design XS LS3 Manifold, thoughts?
So anyone planing on trying one of these out? Everything I'm reading seems pretty positive, gains on a stock LS3, cool design, fits under a c6 cowl. Pretty cool how it hides the fuel rails too... Curious to see if anyone else is thinking about pulling the trigger on one.

Ofcourse, the price is right at $1000 too so def makes it a competitor for FAST and MSD... im really curious to see some real world testing. Looks like they may just be in preproduction at the moment.

A grand with fuel rails if I'm not mistaken, which means it beats FAST and MSD prices.

From all of the testing I've seen, the ported and rod modded stock LS3 intake manifold is about as good as you can get for a street car. Maybe the current aftermarket stuff would come into play for a big cammed, high dollar headed, stroker type setup. For anything I'd be interested in, I wouldn't want to lose low and midrange power to gain a little on the top end. Hopefully, this new one would help with gains from bottom to the top. I wonder if the tune would need tweaking to get the full benefit.

Yeah im curious to see what if any gains it really will make on a stock or near stock ls3. They dont have any real testing results on their page yet but it says they made gains on a stock ls3. I'm in the same boat, I dont want to loose anything down low or in the mid.

Found an interesting article on LS1Tech, they got a discussion going on it over there. Here's the motortrend article... Looks like theyre picking up 8-10 throughout the curve on a stock ls3. Very good read

The key here is the longer runners to me
"In developing the XS intake, Performance Design tested three different runner lengths ("A," "B," and "C") and discovered that using all three mixed between the cylinders offered the best overall performance. The result is a power curve that, according to Performance Design, boosts output everywhere. The company states that on a completely stock LS3 rec-port engine the XS intake is worth 8 to 10 numbers (both torque and horsepower) over a stock baseline across the entire usable torque/power band—something no aftermarket LS3 intake has ever promised or delivered. The company also states that adding a bigger cam, better cylinder heads, boost, and a free-flowing exhaust only accentuates those gains across the power band. We'll know for sure when our test unit arrives!"
