Richard D has kindly slapped my factual figures from my 11.4 run, and this is what it spat out, some good bar stool figures in there if nothing else! smile

Just looked at my timing slips 660ft it was doing 99.43mph in 7.69secs, so that simulation is pretty close!!

I've said it before, and I'll say it again - awesome, awesome, awesome car.

Its *almost* enough to tempt us to the dark side... almost...

That is based on a Cerb drag coefficient of 0.31 as per this topic

Can we have the figures for a .34 - I reckon thats slightly more likely (the T440R was 0.32 and Tuscan 0.34)

Have just tried it and it makes no difference! Oh vMax drops to 206mph. A smaller drop than I expected but then its hitting the redline in top anyway.....

If the Cerb changed into a Caterham shape (0.65 coeff!) it's still giving 11.53 secs @ 127mph BUT the vMax would drop to 171mph.

No, noo, nooo

Based on 0.31 drag it is hitting the redline in 5th - the ideal diff ratio would be 2.6 to match vMax with the engines peak power rpm.

That would give 69 in first, 105 in 2nd and a vMax of 218 mph yikes

You'd have to have testicles the size of Space Hoppers for that yikes
