![]() So since my idle is at 800rpm, I believe that I should target around 53.4 to 66.7hz for my resonator. I am assuming since the basic design of the engine is similar my LS2 should produce the same frequencies. I know that the LS3 engine produces a frequency of 133.3hz at 2000rpm and 100hz at 1500rpm. I mean, it's going to be far too loud to keep my neighbors happy with me when I idle through the neighborhood at 7am in the morning or 2am at night.Įssentially, I want to design a resonator (Helmholtz or ¼ wave) for an LS2 V8 engine that will cancel out a large amount of noise at and around idle to keep my neighbors from hating me, but that won't cancel out any noise at WOT, to be welded in the exhaust. However, with the addition of headers the exhaust will become extremely loud everywhere else in the RPM range. I was very happy with it it was the perfect volume for me and worked as advertised. The Corsa system came with a muffler that contains a ¼ wave resonator, which is great for canceling out drone at 2000rpm on the highway. Initially I ordered a Corsa exhaust system. I want to design something similar for my engine. When I had my 350z, I was a big fan of Motordyne Engineering's Helmholtz resonators for Nissan's VQ series engines.
