Here are more great vids to explain.

This vid shows how sprigns react as rpm increases from 1000rpm to 6000rpm. You can see the small spring has a harmonic wave passing through...
typically material quality, design and theory advance, new techniques of manufacture allowing more far fetched ideas.
The basic aim is to hold the valve as high as possible for as long as possible, because this means that you spend the most time possible at a lift value high enough to flow...
None, there are no cons.
We run mini RPRF (roller path radius followers) which allow alot of load and zero wear with compound ratios because of the rocker ratio changes as lift values change.
If an old racing cam designer from the 70's looked at a stock renault 182 cam he would faint at...
I think someone needs to start thinking about cam design a tad harder and its applications. Ramp fast, hard and as close to the piston as possible, run a stronger spring if needed, control harmonics and use vvt/vtec to its optimum. Gains can be fantastic.
you'd be surprised.........
i only rolled once during my semi-professional days ;)
Besides, brundle is still doing it in the GP masters series..........he's useless......and i mean seriously bad. Alex yoong would give him a right thrashing!
Officially from the factory they came with 166bhp...joy.
As for RR jibberish, its quite simple. 1bhp is 1bhp, mathmatically there is no way around it. And its not very hard to measure either, its not rocket science, you just use a load sensor and a torque arm of a known length........fairly...
i will 100% gaurantee we do not have a MAF.........why?
Because there is nothing between throttle body and air filter.
Like i said, speed density which uses a MAP sensor. This is placed on the side of the inlet manifold on the offside.
