Anyone using the lightweight Mcleod flywheel #464122 on the street? If so what car weight, gear ratio and tire diameter do you have? More importantly, what can you tell me about how it drives with your combo? I have seen spec'd weight for this flywheel in the 20 to 22 lb. range which would place it between an aluminum flywheel and an OEM flywheel. I suspect in a 3,200 lb. car with 3.91 rear end ratio it would be fine.
- EM Not sure what the part number is but I've been using an aluminum FW on the street for years. I just bought a new FW and it weighed in at just under 16 pounds. There is no reason to have all that flywheel weight there. Just beats up on crap. I've used everything from a 3.23 to now a 4.56 gear and 2.44/2.66 and now a 3.09 first gear box and the FW was never an issue.
Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

I ran the MP lightweight flywheel in my 64 Dart, 273/4 speed.

Pro Stock cars have traditionally added flywheel weight given they have no issue getting engine RPM and the added weight helps maintain engine RPM during launches and shifts.
- EM Maybe in the 1970's but not in the last few decades. The entire flywheel, pressure plate and multiple discs can be under 15#. The fly wheel is just a place to mount the very small billet aluminum adjustable pressure plate and the starter ring gear. All the excess material is milled away. The entire assembly is as light as they can make it. Heavy flywheels are for dump trucks.
In theory, there is no difference between theory and practice. In practice, there is.
