Strange day ........





Then it takes me 3.5 hrs to get the last 15 miles home as the M1 gets shut .......

Thanks for a great day stephen and RAOC,pity about franklyns car getting banned on the first run and his mate in the fiat with the brake pipe letting go and had no brakes on the first warm up run down the 2 mile straight,glad john got his car fixed in time to do some runs.
Was good to push my car to the limit in the dry and wet later in the afternoon had no idea how much grip the vee has in the dry i could not get it sliding at all !
Although in the wet its different story had a few little sidewards moments which i was able to catch and a big one i could n't which ending in 2 complete 360 spins but it was all good fun

Thanks for the 2 laps in the spider was really good quite fancy a spider now

Hey, not bad 144 in the wet and plenty more to come but unfortunately no more gears

speedo set to km's then

what did the rev counter show?

the vid showed 141....

the last time imaxed out my spider in normal guise.... it showed 145 mph on the dash but was at max rpm..... so really it was 135,
showing the speedo is a little bit out at high speed

If it was it would have been showing 232!

144 on the vid. Use freeze frame to check.

Best on GPS was 140.6 at 7000rpm. Shift light not showing. Mark will know where that is set as I haven't adjusted it. Can then work out the theortical safe maximum for next time.

Didn't want to push it any further at vmax as no idea what safety margin there is or isn't.

Engine still seems to have more to come and there was plenty of runway and braking distance left.

Seems to be going OK though. The castrol edge 10W60 seems to have sorted out the oil pressure problem for now.

shift light set, IIRC @7400, assuming you have not been pressing buttons, actual ref limiter is somewhere above that. look on the graph from the RR Stephen as it was taken to the limit. that was a good top speed, more than I got IIRC? Even the clio seemed faster than before, maybe wind from behind this time?

[stephendell]

That would give a theoretical top speed of exactly 150mph if it keeps pulling until the shift light comes on:

Engine Speed RPM 7400
Transmission Gear Ratio 0.89:1
Differential Gear Ratio 4.07:1
Loaded Tire Radius 12.34 inches
Vehicle Speed 150 MPH

According to the same calculator 7000rpm = 141.9

A good run in the Spider Stephen.Should make for a quick run down to MACON

looks very good and true readings as GPS marries up with gearing and rpm etc,
shows it has some real BHP we need to put it head to head with my yellow spid
