Apparently superunleaded will iron out the bumps at the start.

Odd how on the same R/R last month my car was given as 195 rear wheels, but only 230 at the fly. (251lbs torque)

Also I thought cars were normally tested in 4th (direct) gear.

Just curious.

[OlberJ]

Whichever gear is closest to 1:1.

Is the Exige 6 geared?

Environment temp 27.7 and 27.8 ???

No wonder I considered putting the roof back on, so so hot !!

Off wikediwowowpedia :

Transmission: C64-speed, close ratio with uprated clutch and cover, open differential

Gear ratios I/II/III : 3.116:1 / 2.050:1 / 1.481:1
IV/V/VI : 1.166:1 / 0.916:1 / 0.815:1
R/final drive : 3.250:1 / 4.529:1

So as you can see 5th gear is the closest to 1:1 gear ratio and it's then used for the run.

It was obscenely hot - I'm completely sunburnt and have a comedy "rudolf" red nose :lol:

But 25% drivetrain loss seems high.

Bet that goes well Bob! i'll remember to give you a wide berth on the roads!

It does that, toyota gearboxes we normally use a 17.5% loss to calculate fwhp.

That's why it's always best to just quote wheel horsepower as that's what you're actually putting down on the road.

[Bob1984]

Ha thanks Baptist! Car sounded awesome again today, even at like 10 mph!

if it was that hot in the garage then your gonna be losing quite a few horseys, i normally get my race car motor rebuilt & dyno'd over the winter & when it broke & needed a mid season rebuild the dyno was down quite a bit & I was well peed off but the car went 100%
