It seems some say manuals show a big differance and others say its same I thought MPH was power and weight related,Had a good read through the manual drag times and its all over the place in regards to power and mph, looking for a calc or a "good" guide line Cheers Link to comment Share on other sites More sharing options...

Assuming that means flywheel.. Edited 16/12/12 11:26 AM by Sharp Dressed Panda 1 Link to comment Share on other sites More sharing options...

As fwhp is generally a guess.. Link to comment Share on other sites More sharing options...

Same mph brad was running in his manual sedan with same power. It's when they have 400-600kw that they all seem the same. Link to comment Share on other sites More sharing options...

Still can't work out what's going on, I have taken it back to tuner and removed all tourque limits. Haven't gone back to the drags since but doubt it will make a difference as the car doesn't feel much better on gear changes.I would say my car should run close to 120mph in manual.
