Forgive me; the gearbox, not the valvetrain is electro-hydraulic. I did however watch the telemetry readout spin above 20,000 RPM with my own eyes.

Formula 1 uses electro-hydraulic valve actuation systems and they exceed 20,000 RPM. Will that be sufficient? No matter what how they're actuated, poppet valves are far from optimal. Coates' spherical rotary valves have been in development for the better part of a decade now but I haven't seen...

I'm truly curious how Cloud Nine Developments can make a Buell look like rubbish.

Might want to keep an eyeball on these fellows... looks interesting. http://www.switch2hydrogen.com/h2new.htm BTW, you didn't mention if your 2.3L Ford was the Lima designed Pinto engine or the Cosworth assisted Duratech unit.. ?

I was given that bit of info from a Ford Co. engineer lamenting the lack of profitability, ergo development/sales incentive in the domestic compact lineup. The MSRP for a Focus SE 4 door is 13-20k, the 325i's is right at 28-31k. Detroit has been chasing the fat margins for so long, they're...

Thanks to the auto unions and federal tax structure, the cost to build a Ford Focus is nearly identical to BMW's cost to build a 325i. The only profitable vehicles for the big three US companies have been trucks/Sport Futility Vehicles. There will most likely be more diesels offered as soon as...

I'm aware of the consequences of improper fuel timing, I was referencing ignition timing, or lack thereof, on a CI engine. (That's a joke son!) CI engine compression ratios are significantly higher than SI, there's more free energy available for reclaimation by a turbo. Manufacturers' use...

Large truck brakes use a reverse-pressure fail safe where a large (LARGE!) spring forces the pads against the drum and the trucks pneumatic system holds them back. This way, if there is a failure in the air-brake system, the springs activate the brakes.

A turbocharger's turbine A/R ratio will have the biggest impact on VE and breathing charicteristics from the exhaust/intake pressure ratio. I fail to see the change that a denser intake charge will have on VE because the intake runner diameter, length, cam events and port volume are the...

Looking over existing hybrid designs, I fail to see why cars like the Prius use 2 motors when an inductive coupling could accomplish the same result (by my wild assed off-the-cuff calculation/assumtions) with fewer parts. Neodymium magnets offer sufficient field density and ultracapacitors...
