So valves are rotated by cylinder pressure, not driven?
Bah, bring on solenoid actuated valves. Much more potential there me thinks. |

I think so too Psycho... will be much more adjustable than even these rotary valves for flow!

Yup, can get rid of throttle bodies while we're at it.

Well I like my power to start at 1000RPM and top out around 6000RPM NOT 14,850 RPM. Can you imagine the scream of the engine at that RPM it would be like a 500cc GP 2 stroke with no muffler!, It would have to have a 15 speed auto with a 3000 RPM stall converter.

They never said it peaked power at 14850rpm... just that they managed to rev it that high.

I do have a question for Steffo, and I'm not having a go at you/him, but have you ridden a high revving 4 stroke motor bike or a 2 stroke? as if you have, you would know that a ZZR250 (learner legal) is a 4 stroke bike and tops out at 12,000 rpm, and will stall at any thing under 3,500 rpm to take off and doesn't produce any real power until the bike is doing at least 7,500 rpm it only produces 26 kW at 12,000rpm, BUT!!!!!! Once you keep up the revs the bike is very quick, 180km/h. So by the time that you have reached 10,000 RPM on the ZZR250 I'm half way down the road in 3rd laughing.

Ok, but that bike only makes 26kW @ 12,000rpm.. of course its going to be a slow accelerator. What's your point? There are plenty of high revving cars that would leave an FPV GT, HSV GTS, and what have you, for dead in almost any gear. Just because an engine can rev does not mean it will produce 95% of its power at high rpm. Especially with a larger capacity, and 8 cylinders. My uncle's 3.5 V8 Ferrari F355 is an example of that. OK, so it doesn't rev to 14,850rpm, but 8500rpm is pretty high anyway. Peaks power (280kW) at 8250rpm, and torque (363Nm) at 6000rpm. Makes its peak torque when an FPV GT hits the rev limiter, and makes less of it then a Falcon inline-six.
But, 80% of that torque is available from like 2500rpm upwards, it has a very good power/tq curve. So, it accelerates good. Now, Coates give no detail of the power curve of their 5.0 14,850rpm V8, but I imagine it wouldn't be so bad. Not like a 0.25litre motorbike engine anyway. |

I never said it was a stocker... If you've ever spun something that does 12,000rpm to 14,500 before, you know theres a big difference between 12 and 14.5 krpm.... and its decidedly unhealthy
5.0 litres breathing through down draft webers turning 14,500rpm? I don't think so.....
