crazy crazy crazy
That's a great vid, it was posted on www.nasioc.com last year, those guys have balls of steel.
Hmm, media player wouldn't play it...
Am surprised he handled it for as long as he did.... Must have a lot of work done to the suspension to keep that vintage 911 tame. Nice sounding car.. Damm i love sound of straight cut gears
Crazy loud.. but what does it mean exactly
I was shocked when he crashed He was doing so good
The gear shifting sounded so good
normal gears have curved teeth (I believe for driveability and ease of engagement) ... straight cut are like the reverse gear in a honda (note how reverse sounds wacked when you wind it out). I believe straight cut gears are rougher, yet provide better power transfer then normal gears... at least this is what I've picked up from reading car forums
this will help explain
Straight cut gears are used in race transmission or cars requiring stronger internal parts. Basically the gears are cut "straight" rather then stock (oem) Helical cut gears. Helical are quieter, but have less material contact, and therefore not as strong. Straight cut gives you a better contact at the expense of noise. That noise is actually not whining it’s the gears slapping together. Scary sounding, but its proven to work, and strong as hell. Usual finds in high horse power road race cars or drag cars. There’s a vid floating around of a gt3 BMW M3 in some European Series with the loudest sound I have ever heard.
Am sure Paul or Steve can elaborate on this more with there race experience.
I have the video if someone wants to post it up.
