Hi guys. Let me introduce myself. I am Erik and quite active on the 456/550/575 forum section of FerrariChat.com. I live in Oslo Norway and also in Villefranche-sur-Mer at the French riviera. I have no Lambo yet, but I have friends with most of Lamborghini’s models. Since 2013 I have been the lucky owner of a Ferrari 550 Maranello. A car form the 90-ies with specs and performance not far from a Diablo. Last summer my buddy and I had a great trip from Oslo to Prague with his 6,0 Diablo. When driving that car, I noticed how much more «growl» that car have compared to my 550 which is much quieter. I am not just talking about the exhaust sound, but more the «wooop» when pressing the throttle down at lower revs. SO, my question is If someone in here have the answer to why this is so much more present in the Diablo...!? Both are V12s, Diablo 5,7/6,0 l and the 550 5,5 liter. The Lambo is 60 degree V-angle, while the Ferrari is 65 degrees. Would that have any impact? As far as I know, this sound comes from the intake. And both cars have one throttle body per inlet manifold (half of the engine). And both goes to a set of big air filter boxes. One engine is right behind you. The other right in front of you. I can’t understand why that should make a big difference? Thanks for all input. I apprechiate it! (No secret I want to make my 550 sound more like a Diablo).
