I have done a search, and have read all the responses. Most of them are either salt racing, or drag racing answers. http://www.jalopyjournal.com/forum/showthread.php?t=320551&highlight=aluminum+vs+steel+flywheel I have run an aluminum flywheel in a heavy ('57 Chevrolet) on the street, and loved it. High Strung SBC. Has anyone run an aluminum flywheel in a light weight '28-34 Ford on the street with a Hot Rod engine? I love flatheads, but thats not what I'm talking about..... A high HP engine. Hard to drive, heavy vs. light, etc. Steel insert flywheels are a given, all aluminum flywheels are a joke.... All responses are welcome. Thanks, Kevin
You will love the throttle response. Nothing wrong with an aluminum flywheel especially in a light car. I had one in my 1969 Z-28 Camaro and it was easier to shift and and revved up like right now. Schiefer Rev-Loc setup. Should be even better in the rod.
I just this week replaced an aluminum wheel in my 32 roadster.For many years I wanted an Al. flywheel behind a hefty SBC,for the snappy response.After a love/hate relationship ,I replaced it with a HAYS sfi 30 lb. wheel. The downside that bothered me was the low speed lurch caused by a lopey cam and the lack of engine smoothing inertia in the steel flywheel, It was lots of fun for performance driving with quick accelerationand deceleration,but I drive in normal traffic most of the time and it was just too jerky. I have an aluminum wheel behind a hot flathead in a 32 coupe with not much problem. The rdstr has 3.55 gears,the coupe 4.11
Being a round track guy, we always want the lightest rotating m***. I've just never tried to drive this kind of set-up on the street in a light weight car. Do you like the 30# flywheel? How does it rev compared to the aluminum flywheel? Kevin
As a former sprintcar driver ,we had no flywheel,and I love a snappy moter. It just was not smooth at low speed. I gotta admit it was fun to go thru the gears,and the car motered down real quick,and the exhaust noise was neat,but me and my wife got soft[70s] and the engine was out due to flat cam,so it was the right time to change.
Ahhh, you got soft. Just kidding. I want to take advantage of the light crank, rods and pistons in my new engine. Just don't want it undriveable. That super fast snap is great!!!
g m makes a 17 or 18 lb steel wheel, i bought one awhile back but havent drove it yet. Figured it was a good compromise between the 30 lb and the aluminum
Im with you on the light rotating weight,as thats what I like Most billet aluminum wheels with a steel insert will weight 12-14lbs, remember you are still adding a clutch and preasure plate..another approx 20lbs Youll be fine,I have found that driving styles and poorly tuned engines usally give a aluminum wheel a bad rap Tony If you where drag racing with a heavy car thats another story
Actually bought off ebay, but i think it is gm performance, corvette road racers use them. However it may only be for 1 piece rear main cranks
