now that i have a good video camera i will have to try to collect some more of my favorite engine sounds.
F1 cars sound 10 times as amazing in person as they ever can on a computer. any engine can sound good all wound up, but 2.4liters at 19k rpm is jsut a wild noise that i can't even describe. you can ask jsutin what it sounds like through a cell phone, i called him and let him listen as the field went by for a restart at the USGP one year. lol
another favorite is the sound of a ferrari downshifting off the banking during the 24hour race at daytona. it is sick, such a tight sound, and flasshes of flame out the exhaust every time a gear is dropped.

i woudl offer to let everyone hear the sounds of the diesel powered audi prototypes, but there really isn't much to hear. just a sort of whoosh as they go flying past at 180+mph. lol
