Road and Track Chimaera ?

well yes obviously disregard the comments of the owner who has first hand experience of both cars on the same roads and as the same driver because on track you've out-driven other people..
I was just speaking from experience, not trying to offend.I agree that a chim/griff suffers from understeer and will never turn in like as Elise etc. This is where we have to take a bend a little slower and power out!
I recently started experimenting with stiffening up the damping substantially on the last sprint day that I did with positive results regarding turning in.
Sadly this was at the end of the day so I am looking forward to tweaking more at the next one.
You should try one of these sprint days. As you are the only car on track then you can act like a hooligan sliding the car round the bends on the throttle which gives you the opportunity to analyse exactly what's happening in generally a safe environment.

Must admit - I hadn't heard of this TVRCC sprint series - I had wanted to use the Chim for MSA sprints / hill climbs but you have to have 6 events signed off in a car under 2 litres before being allowed to drive anything else. This might fit the bill perfectly.
Are you sure about that Keith, I thought the 2 litre thing was just for racing cars (single seaters/sports libre) and that it didn't apply to road car classes.I will have to check my blue book.
OK, checked it, Section 7.1.5 applies
Any driver competing in a Racing or Sports Libre car manufactured after 1960 of more than 2000cc (or 1428cc if forced induction) must hold a National Speed A (Open)or Race National A Licence (H16.1.1) unless the car is currently licenced for use on the public highway and competes in the event in a road legal condition.
So if your Chim is road legal there is nothing to stop you using it in MSA events.

Murray, I see you're a subsea consultant.... Do a bit of that myself 
Whereabouts ?I am currently whoring myself to Total in Angola.
Don't s'pose you know Tim Cheshire?
I was contracted to them until March last year, Subsea-Engineer in Drilling and Completions. Working with Derek Ramsey, Joe Heron, Grant King etc. I heard there is going to be a bit of a clear out there though.

Ah! The benefits of actually being in possession of the BB, rather than trying to find out. Thanks you Corpulent To...that seems rude.
You can access it online - http://www.msauk.org/uploadedfiles/msa_forms/blueb...Lots of information, not all of it easy to find or decipher, good luck with it.

Have you tried putting a small amount of toe-out on the front to improve turn-in? I believe most of the racing Tuscans do. NickOrangeTVR said:

I had heard that as a general thing but not done so as the car spends a lot of time on the road.My car has very little toe in, if any.
I'll do a bit of experimenting at the next sprint.
Your car WILL be toe out whatever your static measurement is, as when the bushes are loaded the wheels will be all over the place. Racers can set toe out when they are using spherical bearings instead of bushes, as well as on track there tend to be less uneven surfaces to cope with that introduce the 3D effects of bump/rebound angles (TRE & camber swings dynamically change toe).
This IMHO is predominantly why some peddlars can get their (or any) cars to cope with bends better than others as they find the best attitude to approach turns with, ie loadings in their favour instead of fighting ~ you have to kind of visualize it like driving a chassis made of string IYSWIM.
