LATE TO THE PARTY
The one thing we can count on when testing “all” the LS3 intake manifolds is missing one or two. After running 20 different LS3 intake configurations, we came across a couple of stragglers who were late to the party. Naturally, we wanted to include both the Edelbrock Pro-Flo XT and the Performance Designs Carbon pTR, but this was easier said than done. Unfortunately, between the first round of testing and when the new arrivals showed up at the dyno, we had a problem with our LS3 crate motor. During testing for another story, we got a little greedy with the rpm and managed to tag a few intake valves. We were not able to get the problem solved in time to run the two new intakes, so we did the next best thing: ran them on another test engine. Rather than not include them in the test, we compared them to the stock LS3 intake on a larger 415 stroker (Wiseco forged internals, AFR LS3 heads, and healthy COMP cam) we had sitting around. While you won’t be able to compare them to the others, you can still see how they fared against the stock LS3 intake.
