Default real performance of a real haynes roadster

just a bit of an update for you all out there as I know I have not been in of late.

just wanted to share some real life performance of my car that I have been devloping over the last few years on road, track and hillclimbing

car is 505kg dry and empty and 705kg wet and me sat in it (325F- 380R)

top speed at castle coombe stright 118mph (5th)

2 people 0-65mph on warm toyo r888 3.42 secs (no wheel spin)

best time at wiscombe park hillclimb (1000 yards or 914 metres average gradient is 1 in 13.6 and the steepest section is at the Martini Hairpin where it is 1 in 6.9.)
dry 46.51secs semi slicks, 48.50 std road tyres
wet 50.12 std road tyres

I still run the same 1800cc zetec silvertop on fuel inj throttle bodies but now run piper fast road cams in a ported head (was 165.1bhp @7100 before porting)
tall first ratio kit in type9 now and 3.92 lsd diff
toyo r888 med on 15" pro race 1.2 wheels all 20psi road and 16-18psi comp
350lb front springs and 275lb rears (DONT recomend for open diff and normal tyres!)
2.9 turn rack

dont waste time fitting rear discs or bigger than std front discs just use vented fronts and try and reduce unsprung mass as much as possible
