Proposal for a new 2021 Sevens HPDE in SC - Gauging interest


Recommended Posts

@fastg I agree - CMP is a very promising track.  Freshly resurfaced too.  The message from Steve was that it suits se7ens well now.  

 

@Kitcat Sadly I will now not be making the August option at CMP and it will probably not go ahead[.  I had an expensive day yesterday when my gearbox blew up on track.  It locked up solid throwing me rather violently into your special grassy regular parking spot at Thunderbolt at the Devil/Octopus.   I thought of you while sitting there waiting for them to stop the track and recover me.

At least you weren’t in the “parking lot” due to your own driving stupidity. And you didn’t eventually drive out if it bouncing off the mamouth rocks NJMP thoughtfully left there, so you didn’t return to the pits with 2 flat front tires and 2 bent front wheels. Thx for that memory Croc(:.

 

But back to the present (TG), why did your transmission lock/explode? Is it the Cat 6sp? Any warning signs before disaster struck? As I mentioned in a post a while back, the seals on the 6 sp need to be replaced semi-regularly.

@Kitcat  Yes it was a Caterham 6 speed.  Now I suspect it is a metal casing full of shredded metal based on the many expensive noises it makes when you try to rotate the wheels.  Very little warning sign - I changed down from 4th to 3rd and felt the change be slightly unusual - stiffer and shorter than normal in my hand, no noise indicator.  I was sensitive to gear changes because I had been shaking down the Holden in the previous session to decipher its gear change issues and evaluate suspension set up changes.   So I backed off the speed immediately and was planning to come to the pits to check it out.  I made it another 500 feet before it all locked up and I did a Kitcat-quality tank slapper.  Fluid in gearbox was fresh and at right level.  No leaks or prior issues.  Changes felt clean and normal right up to the last one which is where I sensed a problem.  Clutch is a year old and feels normal, even after breaking the box.  I could still select gears cleanly with engine on stationary with clutch depressed so assume its output shaft area thats broken.  It was very sudden.  Its 11 years old and 10,000 miles, most of that on track.  So with that perspective maybe not a surprise.  Replacement box secured and the old one will be rebuilt.  These things happen  :classic_rolleyes:
