SXN16V has a point to get the truest figure on a chasis dyno the run should be done in the gear that is closest to a 1:1 ratio, which for the C60 gearbox would be 5th, as below data shows (from www.toyota.com.au) Transmission description Six speed manual - Transmission code C60 Gear Ratios - 1st Gear 3.166:1 - 2nd Gear 2.050:1 - 3rd Gear 1.481:1 - 4th Gear 1.166:1 - 5th Gear 0.916:1 - 6th Gear 0.725:1 - Reverse Gear 3.250:1 Differential ratio 4.529:1 But as has been said before The way to compare dyno figures between 2 cars is to remove all the variables i.e same Dyno, Day, gear, tire pressure, wheel\tire size...blah blah blah.. even then there are all sorts of things that can vary figures. A 0-400m time slip would be a better comparison as it is a combination of car performance and driver skill.... what good is a fast car if you cant drive it????
