Lightweight flywheel options and selection criteria.
My experience consists of at least 50 road course days flogging a variety of street vehicles not race cars over 20 yrs or so. All were set up for surviving hot laps. I hope this qualifies to express an opinion based on experience.
The fastest car had a wicked pump gas stroker 416 with an sfi 30lb flywheel. The reciprocating crank rod piston mass was so light that the car did not need the light flywheel to get the engine to snap when rev'd. Many stroker engines are lazy due to poor cam choice and poor tune up. Herb McCandless made the cam choice btw
My clutch choice was and still is different that what others used and i would still use that configuration if i were to build another street car that also runs on the track - because it works. I have the engine and steering wheel so far for the next car...
As for the tune up - the tune up is very critical esp with a light flywheel configuration. Most cars do not run well even though the owner operator thinks otherwise
Yup, if I had to get something out of tight corners I’d have a 30 pound wheel.
I grew up when 50 pound flywheels were standard stuff in the drag racing classes I care about.
Today a 4 inch stroke is normal. Even a 3.5 inch stroke would have been considered LONG by Modified Eliminator engines back then.
I had to get my head around why not to use a steel flywheel.
I broke more **** and cost myself more money breaking **** that was considered bullet proof it’s not funny. And that is heavy flywheels and junk clutches.
I’ve been sitting on a video for a few years. I’ve been wanting to post it but I took it without the guy knowing it.
I at least wanted to show him first, but I’ve never seen him again.
I think it’s been long enough now that I can post it.
It’s a learning tool as to what a jacked up clutch, a heavy flywheels and maladjusted traction bars do.
I’ll post it up in a bit.
