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.

From memory it is higher.

My F6@ 140kmh = 2,000rpm in 6th, but the TT was 2400rpm at the same speed.

Hi

Falcon BF - 6th gear (auto) needs 1585 RPM for 100km

Turbo Terry - 6th gear (auto) needs 2012 RPM for 100km

Hope this helps

I don't know whether you have a Turbo Terry or not but they sit on about 1930 or so at 100, and at 110 it sits on 2000.

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 Falcon

Not so Orrie. 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 3.46

A 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.

Hi raptor,

Mate you are spot on ! 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.

That sounds more like it! To hard to tell with the T speedo, its not as detailed as some. Its bang on 2000 at 110 though.

Hey guys. Diff ratios for the TT are 3.46 front and back
