or you could video tape it on a decent quality video camera and put an aftermarket tach so we can see exactly what it hits.

 

do you even drive a ralliart? ^^^^

 

well i for one am not twistin that many rpms, but the power is still there. i do believe it (with a bit of uncertainty), but will not try it myself anytime soon. right now the 7000 limiter is as far as i care to venture, but i have seen it may times lol.

 

Does anyone know the 4g69´s rod to stroke ratio?? That might give us a clue as to what rpms the engine can rev safely.

Some time ago I read at a honda forum that the higher the ratio, the better...Honda B series engines (that can rev up to 8000 rpm stock) have like a 1.52 or 1.54 rod/stroke ratio, and motorcycles that can rev up to 15,000 rpm and even F1 cars have a rod/stroke ratio of about 2. something or more.

 

Hey, Juan how is Ricky ? Is he ok ? Knowing the power of his car and crashing into a wall its not easy to sustain!

 

yes, he is ok, but the car.....

 

I was under the impression that the compression rate was more improtant for higher RPM our cars only have a 9.5:1 were as cars like Honda have a much higher ratio 10.5:1 and even higher... but as for what the internals will take I think you will find that they will take a fair amount of abuse

Other areas to concentrate on in getting more speed and more rpm is a better gearbox, the ratios are not really all that good for such a large CC motor and the rev limiter is a pain I would much rather see it at 7500rpm

Anyway I will be able to find out more info in the next week as my car is going to be getting some major work done to it....

 

my brother has a Silver04 RA5spd. Fun little car. You don't need to own a Ralliart to understand the fact that it is practically impossible to his such high rpm's on stock internals, or at least the stock crankshaft. This car WAS NOT built for racing. Don't even try comparing it to F1 cars, they are ment to be revved up to 18-20k and have the components built to withstand the abuse. Even if you did hit that high...why bother? The powerband starts leveling out and dropping at 6,500 if im not mistaken.
