After long time being hold back due to business and traveling abroad, yesterday finally managed to install Harry's Lap timer application which has the option of measuring 100-200km/hr. I dont know how accurate this software is but according to various reviews it seems to be close to reality. Being very tempted I decided to take out my Z for some testing.
Outside temperature was 12C
Fuel used was 100 Oct (Shell Racing)
Weight of car 1440kg without driver and 1/2 tank
Last dyno was 476whp; car now is running without cats probably running a bit stronger
3.91 final drive
19 csl wheels with 235/35/19 & 265/30/19 Michelin SS tires
Run was recorded at 2% downhill
I know that results are way better than any of my expectations and surely will create lots of arguing and discussions, but I thought to share it with you all.
