obi Member 150 Member For: 18y 7m 28d Location: Qld Posted 08/04/07 02:59 AM Share Posted 08/04/07 02:59 AM Can any one tell me the RPM of the Turbo Territory at 100 K's ? Is it the same as the XR6T or higher as it appears the diff ratio's are different. Link to comment Share on other sites More sharing options...

Orrie Member 68 Member For: 19y 4m 27d Gender: Male Posted 17/05/07 11:28 PM Share Posted 17/05/07 11:28 PM These figures are calculated - theory - based on gear ratios. So that is what the engine REALLY should be spinning at to acheive. Of course different tyre sizes, pressures, wear etc as well as tacho error will effect what you see on the tacho.I guess the important bit is that a terry will be spinning about 25% faster in top gear compared to a FalconOrrie Link to comment Share on other sites More sharing options...

You seem to have acknowledged that different tyre sizes need to be considered but then not taken them into consideration in your calcs.The XR6T final drive ratio is 2.73 and for the Terri Turbo 3.46A quick divsion gives 1.267 and I assume this is where the "...about 25%..." comes from. Correct if the two cars had the same size tyres.The XR6T has 235/45/17 (calculated dia. of 643.3mm)The Territory has 235/55/18 (calculated dia. of 737.7mm)This time a division gives 0.872 and thus the larger tyre only needs to spin 87% as fast as the smaller tyre to cover the same ground.The net difference is 1.267 x 0.872 = 1.10 or in other words the Territory engine will be spinning only 10% faster for a given speed in top gear.

My Bad !I forgot to update the wheel size 17inch to 18inch for the TT ghia. New Clacs say that the Terry should be spinning at approx 1770 RPM for 100 klicks.Orrie Link to comment Share on other sites More sharing options...

To hard to tell with the T speedo, its not as detailed as some. Its bang on 2000 at 110 though. Link to comment Share on other sites More sharing options...
