AndyB Posted June 14, 2014 Posted June 14, 2014 Today's the day I push my luck and run my 50 year old twin cam to the limit. My favourite charity auto slalom event, I'll post photos later. With me luck! http://www.carcontrolschool.com/special-event-days/2014-james-fund-exotic-car-day/
Automoda Posted June 14, 2014 Posted June 14, 2014 Um. Hasn't anyone told him about the pre-race ceremony? You know, the one that you MUST do before racing a vintage car or else you anger the Lotus gods and a piston goes through the oil pan?
twobone Posted June 14, 2014 Posted June 14, 2014 Andy's twin cam is a fruity little ripper. Hope the day goes well!
AndyB Posted June 14, 2014 Author Posted June 14, 2014 Thanks for all the well wishes. Weather was great, good turnout cars, donors and the Seven lives on.
DeanG Posted June 15, 2014 Posted June 15, 2014 A well maintained twin cam that has reasonable carbonation settings and isn't run at too high an RPM will live a long time. The trouble is the higher they are reved the better they sound.

It sounded marvelous and kept pulling strongly right up through redline.

You are correct, most cars I've driven run out of oomph 500-800 RPM before redline and grabbing another gear before redline is faster. Not so the twin cam she pulls right up and through the redline if allowed, luckily I have an old rev limiting ignition rotor. I've only ever hit it a couple times but it is a reason I have not gone Pertronix as yet.
