i used to use that back in the day (v3, i believe), but then i learned photoshop. was glad i did, as it's so much more powerful.

Anyone else stoked for Hayden? Other then the engine drama he once again proves hes got the skills to pay the bills. I recently watched some of his old TT races he was pretty goddamn awesome.![]()

Pneumatic valves means higher revs can be achieved.What ever happened to Toseland? Pneumatic valves... so does that mean no cams? i guess that could mean less weight, less rotating friction, and easier tuning. Wonder what these crazy kids will cook up next. GREAT chopping guys. Im semi consious and still rofl
Reducing the number of moving parts that can fail is good engineering. Racing engines often failed at high speeds because mechanical springs were unable to close valves fast enough, leading to engine failure when pistons struck incompletely closed valves. Renault's innovation was to replace steel springs with light weight compressed air bellows that could respond more quickly and reduce the possibility of valve crashes, other than from leaking bellows. Additionally, the amount of seat tension required to keep a coil sprung valve under control results in peak lift loading drastically higher, with added stress to the entire valvetrain as a result. Pneumatic systems, sharing a common reservoir of pressure retain a more static level of force, controlling the valve effectively, without any attendant peak lift load increase. To avoid bellows failures, air springs are replaced often.
