Not Ranked
Thanks Rick. Interesting stuff. I’ve never heard of using aluminium alloy conrods….how does the strength of the rod compare to a forged alloy steel rod? Their section dims would need to be bigger, surely, and then they lose some of their weight advantage, wouldn’t they?
Agreed, as near to perfect balance as possible is essential for high revs. And don’t forget, I don’t want or need big power. The original FIAs were winning with 380bhp, so 300 to 350 flywheel hp is easily enough (and OK if I find I need more a year down the track, I deal with that at the time). It would seem this thread is already past its use-by date, but what the heck …. so what’s wrong with chasing revs, but not chasing horsepower? Generalising here… what’s the hangup with big horsepower numbers. Is it a geographic thing? So, well and truly established that I’m not after the big horsepower numbers, does that make it easier to spec an engine with good enough manners from 1500rpm to 6500 or 7000? If I use were to use something like Dynatek FI, does that make it simpler?
Cheers,
Glen
