A point of interest for RV8 owners regarding 95/99RON.....

[King Fisher]

Well it seems I may have stumbled on something that may be of interest to Chim and Griff owners. It's come to my attention that the factory used to set the cars to 22BTDC at 4k with the vacuum advance off. Now, the generally accepted value is 28BTDC at 4k with advance off. Could it be that the factory set the cars at 22BTDC for 95 octane fuel, and this could be why some cars seem to run fine on 95RON, but others pink when run on it? Just a theory!

Therefor some are a bit quicker?

I think unleaded was a new thing when my car was made, super unleaded hadn't been invented

How do you know this.

Can you confirm that it is anything other than hearsay.

I've been around TVR's for long enough to be fairly convinced the factory never set anything!!!! they certainly never set anything the same twice...

and whilst im on which bd designed ( i use that in the loosest form) the damper mount on the chim/griff lower front wishbone...

As all cars will have been serviced since leaving the factory - it's fair to assume that
cars will have had the timing reset anyway.

Designed? What makes you think it was designed ?

Someone who never had to undo one after it had been in service over a decade

It's bad enough using new wishbones and new bolts.. Powder coating is a pain in the ass too. Having to grind and file the pc off, chipping other bits so the bolt will go through and the damper to fit!

One of my old wishbones still has a damper in it and the bolt well and truley seized in the damper bush

Because Nick knows ex factory who set them at 22BTDC, yet TVR Power set them at 28BTDC.

...more like "throw the bits into a bag, shake it up and see where they stick together."

I tend to describe it as "A pre-built kit car that was assembled using whatever bits they managed to 'scouse' on the way home from the pub the night before fitted to a chassis knocked up from hacked up scaffolding pole robbed from the nearest building site"...

...but I love her just the same.
