Re: Vintage Ford V8 film

My Dad drove a Nash Rambler with a straight six and electrically driven supercharger off of something industrial that had the luck to land in a wrecking yard near Romulus. This was when he was commuting back and forth from Romulus to UofM in the late 1950s. They did a top speed run at Willow Run and...

Re: NA Engine With No Damper?

I believe dual mass flywheels' typical function is to smooth out the power delivery "out the back" at low loads and heavy throttle especially with engines with few cylinders. Variations in instantaneous rpm. Not to tame the crank twisting events. Yes, I agree that is the typical function. The chall...

All the Cosworth DFV and DFL F1 engines ran with a Holset vicouse damper.

Was this in addition to the quill drives for the cams or is this another (or the proper) name for them?

Re: NA Engine With No Damper?

... Your car will go faster with a good damper. DV I might be misinterpreting some of the queries but I think that they might be referring-to or comparable-to a higher sweep rate for an engine to a given desired power level due to lower mass versus the same engine being able to achieve an ultimatel...

Re: Per DMFW

The way I understand it is the dual mass flywheel is there to attenuate low frequency vibrations more related to torque pulses. It is a different function, and I do not believe this would have any control on torsional vibrations. You would think the damper should be on the opposite end of the crank...

Re: NA Engine With No Damper?

Dual mass flywheels could be (and have been) devised to help reduce the torsional load on the crankshaft from the rear. Camshaft dampers also exist.

I think a rule would be introduced to stop an "arms escalation" that could reduce competition and participation. Maybe such rules already exist.

Re: BBC windage/oil control pan mods

I know it is easy to drill out rivets BUT it would be nicer to use threaded inserts. Future changes/ideas etc.
