Last Friday (31st October) I tackled the awesome Cadwell Park at a Javelin organised open pit lane track day. After watching a few onboard videos the narrowness of the track and some high speed sections seemed quite daunting, but its probably one of the best tracks I’ve driven on. Technical, full of character and interesting, and the Mountain proved to be as fun as I’d hoped.
My earlier post outlined some of the changes I’d made to the car and its current spec. Performance wise there weren’t any major upgrades, just a few changes.
It was great to be back on track with the Great Danton after so long but it was also a good opportunity to do some benchmarking. Cadwell Park is one of the tracks on the Time Attack UK calendar and this would allow me to see at what performance level both the cars and drivers compete at, as its a championship I would be interested in competing in. I know my car is close to stock in terms of performance, with nearly all the interior and leather trim still in the car, but it would allow to gauge what sort of work would be required to be competitive.
Next to my mates 318 ti.
Onto the highlights:
SR20DET T28 @10psi
Bridgestone Potenza RE002 Adrenalin 245/40/18
Approx. 1265kg wet weight
The fastest lap of the day was a 1:51.95 during my last session. The track was completely dry by that point after a bit of fog and dampness in the early morning.
The car went without a hitch all day, but I did finish the rear pads again like at Donington; down to metal. The rear pads were EBCs again but this time I went for the Red Stuff compound, which I thought would last longer but only did a couple of thousand miles on road and this track day. Not great. Some Ferodo DS2500 would be a better choice, which I have on the front, but they are nearly 3 times more expensive for the rear; the price difference for the front pads is much closer. I had some temperature strips on the front calipers which registered up to 188degC, which is fine for the brake fluid.
Overall I think I need to upgrade the braking system; not only do the bigger tyres offer more grip but they have a slightly bigger diameter thus reducing the brake performance. Future work on the braking department will be bigger discs at the front and to rebuild the front calipers, and get some 2 piston rear calipers (Z32) to balance the braking system.
Had some good battles out there with a TVR Cerbera, 330Ci and a racing Citroen AX. There were a few great cars that I’d hope to run with but we’d go out at different times or be on different ends of the track during a session, and it’s difficult to slow down to let them catch up when you’re having a blast. It’s the same thing when you reckon you should come in and rest the car: why should? I don’t want to stop! And then you end up on track for an hour and you’ve worked up a sweat.
The RE002 tyres performed very well for a sport tyre as they could easily hang with semi-slick draped cars in the corners, though for my next track day it’ll have to try the set of R888s I have. Such GRIP!
Time Attack UK
So I’ve posted a list of lap times around my fastest lap showing where the Great Danton currently sits among them; these times are from this year’s Cadwell round and only a small portion of lap times are shown.
– 1:42.097 – Club RWD – Mazda RX-7 FD3S
– 1:43.802 – Club 4WD – Nissan Skyline GT-R BNR33
– 1:45.093 – Club NA — Honda Civic Type-R FN2
– 1:48.380 – Club FWD – Vauxhall Astra Turbo
– 1:48.810 – Club 4WD – Mitsubishi GTO (600hp)
– 1:50.688 – Club NA — Ford Fiesta ST
– 1:50.706 – Club FWD – Vauxhall Astra
– 1:51.95 – Great Danton
– 1:53.213 – Club FWD – Alfa Romeo 155 V6
– 1:53.820 – Club NA — Peugeot 205
Overall I’m very pleased with how the car compares with the current crop of Time Attack machines. If I remove and/or replace the leather interior, tune to 270hp and slap some semi slick tyres on I think I could shave the 10 seconds needed to compete in the Club RWD class, given that a couple of seconds could have been saved by improving my lines and pushing a bit harder on the braking points.
