3000 rpm is nothing for the puma really.

Didn't notice what the revs dropped to. I will try to remember to look tomorrow. 110 Hardtop

If you change at around 3000 and change quickly it drops to just above 2000, 2100 I would say 110 Hardtop

When I first got my 2.2 I was changing at about 2000 rpm and it was bad..very bad! now I am changing around 2500 and changes are smooth and clunk free. After following Pete's advice after a phone call regarding the change between 1st and 2nd and training my right foot the Kangaroo problem has also gone.
Really does seem to be a case of just getting use to the beast. |

Hi Folks,
Well I've had the new 90 for a week now and I'm just about clonk-free accelerating through the gears (the 3000 RPM rule is the simplest) but there is still one scenario that has me jiggered: The new engine is very torquey and will happily trundle along at 1500-2000 RPM on the flat. A lot of the roads out here in Oz have an 80kph (50mph) speed limit which equates to roughly 1500 rpm in 6th gear. The only trouble is that when you come out of the lights and accelerate through the gears, you hit 80kph at ~2100 rpm in 5th which means a guaranteed clonk into 6th. I've tried changing from 4th straight into 6th which inevitably also results in some complaints from the drive train. So the two options left to me seem to be break the speed limit or clonk  Paranoia has probably set in. Do you think it's time to take it back to the dealer, or do you think think things will improve as the Def continues to get run in?Last edited by Gus on 17th Nov 2014 1:00pm. Edited 1 time in total |

When I test drove my 2010 2.4 I said to the salesman 'when is it best to change up?', his reply was 'the engine will tell you'.
 So then, armed with this pearl of wisdom my decision was around the 3000 mark so I'm well chuffed with Mr Bell's remark regarding revs. Works for me. |

Gus, it would seem from your findings that 4th/5th gear doing 80kmh is where you want to be and not in 6th ? 6th is to high for that speed.

Hi Pete,
I just corrected my last post, realised I was out by a gear 4=5 etc 
I think 2500rpm in 5th equates to roughly 90kph or 55mph, haven't hit 2500rpm in 6th yet! Gus |

So what's a good cruising rpm for the 2.2 TDCI engine then? The engine pulls fine from 1500rpm in 6th, should I be leaving it in a lower gear until I hit 2000rpm? |

cruising at slow is speeds under60/70mph id personally not go into 6th until after then.

Pete you are the GURU...no doubt about that.
But, I couldn't see any need to be in 5th at "60/70 MPH"? Pickles. |

I'm posting a lot of the road speed V rpm's from memory as I've been driving my 2.2 Ford Ranger for the last couple of months while the defender permanently strapped on the Dyno, the Ranger has a higher gear ratio than the Defender which makes it harder to remember exactly sometimes as I'm not in the defender every day.
Interestingly the ranger is a lot higher gear and drives totally different to my Defender, I may even think about raising the transfer box ratio on the Defender to 1:1 to see if I can make it match. Its also always returning 30+ mpg which is great. Pete. |

Pete, Interesting I feel my 2.4 90 (standard with only the air box mod done) could easily cope with a higher gear, when you think the same engine pulls about industrial 130s with heavy trailers a 90 should be a doddle. My 118d BM pulls 40mph per 1000 revs in 6th and it makes the 90 fell positively under geared. I have looked at Ashcrofts web site repeatedly comparing what different t/box or diffs would give me. I thought about 35mph/1000 revs would be about right. Would be very interested to hear the results from anyone whom has done it. DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy Last edited by LR90XS2011 on 18th Nov 2014 6:14pm. Edited 1 time in total |
