well i have gone for the following:
picked the max weight for the car, as mine is a derv with A\c so figured it will come in on the tardy side so in
lbs = 2921
18% drivetrain loss - been told that from rally_matt as it is the same across all pg1's cars.
RR think it is default at 0.015%
drag co-efficient = 0.320 for a hatch or 0.330 for a saloon (found it on google)
frontal area = 2.030
and i have then used the gearbox man website in conuction with the haynes (gear ratio\final drive) to work out the various speeds\revs for 3rd gear - need private road to do it for 4th gear.
set mine to
start at 1250rpm@ 19mph
end at 4500rpm@ 68mph
tbh i am not sure that i will ever use the dyno side other than just to see, but i was more after the lap timer\ and if i take it to pod would be interesting if it matched the expensive equipment there for the timed run part.
