highly unbelieved on XPF as a guy on theyre who has cams is only pushing out 174 atw like mine and he has spent just shy of 3.5k getting it theyre

Tim, you say you have bigger wheels, surely the tyre aspect ratio compensates for this and will have a rolling circumference that is near on the same as the OE ones? For those mods I would say 6.5s 0-60 being probably closer to the mark, but like you say, getting those times takes alot of practice and getting the take off technique right. It is just a yardstick they use to compare cars, joe public won't be able to achieve it for sure.

here's roughly what times you're looking at if it really was running that power.
Bearing in mind rolling roads aren't the most accurate of things...
Power at Flywheel (BHP) : 195
Weight without Driver (KG) : 1285
Power to Weight Ratio (BHP Per Ton) : 154.19
0 - 60 (Secs) : 6.98
0 - 100 (Secs) : 18.23
60 - 100 (Secs) : 11.25
Quarter Mile (Secs) : 15.39
Terminal Speed (MPH) : 91.87
Drag Strip Quarter Mile (Secs) : 15.19
Drag Strip Terminal Speed (MPH) : 93.46

These figures dont take into account torque or gearing though. The ZS180 has a good amount of torque and a close ratio box so should be a bit faster than the above calculations.

hmm torque doesn't come into the equation in a straight drag on a flat road..

3) The formula’s only use three items of easy obtainable data to produce the figures, these are Flywheel Power (BHP), Kerb Weight (KG) and Drive type (4WD, FWD or RWD). Formulas do not take into consideration other factors that could also affect real life figures, e.g. torque, gear ratios, aerodynamics, air density, temperature etc, these are not easy obtainable.

4) The 0-60 (and 0-100) quote takes into consideration an average amount of manual gear changes. In real life times can vary if an extra gear change is required before reaching the quoted speed.
Those figures are only theoretical. Pretty sure torque doesnt only affect the car up hills

some good info theyre folks id say 6.5 is about right although in my head its quicker but isnt everybodys car

I dunno about the wheels Stamford i always thought the bigger the wheel the slower the acceleration or top end speed

Feel Free to correct me if im wrong
