Rolling road tuning/diagnostic for TVR in SW

[sgrimshaw]

Any recommendations as to where to take my Chim 400 for a rolling road diagnostic / tuning session in the South West.

My Scooby feels SO much quicker than my Chim, surely this shouldn't be the case. RR only way I can see to check the car properly.

Thanks in advance,

Simon

Took mine to a Mark Adams session in Cheltenham.
Mark Adams ia 'the' RV8 god - if you want more power get in touch with him.

Hint - everybody has trouble getting in touch with Mark Adams - it's been posted on PH so many times I'm not going to bother looking for a reference - doo a search and you should be OK, otherwise mail me.

Woo Hoo - more power!!!!!
All the best - Nacnud

Thanks Duncan,

I have emailed Mark via his profile.

Interpro down at Thornbury are supposed to be very good. Not too difficult to get in for a quick power run, but for a full-on tune I've been told they're booked months in advance.

Thanks Deadlock.

I'll check them out.

Heard nothing from MA so far ...

Depends on the scooby but none of them are slow, even the slowest is on a par with a Chim 400. The base 4 door turbo was tested by Performance Car and Top Gear magazine in '97 and found to do 0-60 in a little over 5 seconds - around the same as 4 litre Chim. When Autocar tested the 5 door hatch version, its 30-70 time was a second faster than a Porsche Boxter. So in a straight line a base Scooby should be about the same as your chim. Depends on your version (cant tell from profile) but a base model Scooby shouldnt feel significantly quicker than your chim.

Hi Jamie,

The Scooby is standard, apart from having a 1999 ROM instead of the 2000 one (smoother running).

It feels a lot quicker than my Chim.

Turbocharger = greater perception of speed. Off boost you effectively have a Mondeo, on-boost a monster. TVRs have a very linear NA power delivery so like for like will always seem slower.

Also, the Scooby's 0-60 times don't really tell a lot when it comes to the performance. 4WD traction trumps all off the line and help to play up the 0-60 time compared to other cars. For example my FWD car with a turbo is knocking about 300bhp, but I'd be lucky to get to 60 in under 6 seconds (but admittedly a FWD car is the worse example).

0-120 and quarter-mile times are far more accurate asssessment of a car's straight-line potential IMO.
