![]() We also included torque production at 4,000 rpm, since street driving entails much more time in this part of the power curve than at maximum rpm. Understanding this, we included average power production from 3,100 rpm to 7,000 rpm. ![]() This is a significant chunk of change, but peaks only tell part of the story, as acceleration is a function of average power production. A review of the data will reveal that the difference between the least and most powerful intakes was over 65 hp. The internet will be quick to grab the peak numbers from this test and run with them, but there is much more to an intake, or the power curve it produces, than simple peak values. Matching this range with the right cam timing, head flow, and displacement, and you have a winning combination. The runner length (and other design variables) determines the effective operating range. Intakes should be thought of in terms of engine speed (much like a cam). 617/.624-inch lift with a 113 LSA), and would be better suited to something with wilder cam timing, or more displacement, or both. This is an important point, as many of these intakes were not designed for our mild cam-only LS3 crate motor (specs on our COMP 54-496-11 hydraulic roller measure 231/247 degrees at. Oh sure, it is possible to shift power production higher in the rev range with shorter runners, but this usually comes with a trade-off in low-speed torque, sometimes a significant one. Unlike the previous cathedral-port examples, even the mighty Trailblazer SS (TBSS) manifold, the stock LS3 intake, has proven tough to beat. ![]() Provided here for your viewing pleasure are the results of part 1 on the EFI intakes.īefore getting to the results (like you haven’t already jumped ahead!), we need to point out a few facts, the first of which is that the factory LS3 intake is one of the best OE intakes ever produced. Unlike the previous adventure, we decided to split up the EFI and carbureted intakes and test them separately. Not surprisingly, the aftermarket jumped on the band wagon to offer all manner of intake combinations for the new cylinder head configuration, so it was only natural that we had to test them. Blessed with what were essentially race heads right from the factory (flowing 315 cfm), the rec-port motors offered even more potential than the factory cathedral-port combos. GM eventually replaced the cathedral-port heads with high-flow, rectangular-port heads when they introduced the LS3, L92, and L76 motors (to name a few). The problem with doing the mother of all intake tests for the cathedral-port guys is that it left out the LS3 owners. That test included every cathedral-port intake we could get our hands on, including the various factory versions. Way back in 2015, we performed the mother of all LS intake tests by running 20 different intakes designed for cathedral-port heads .
