Thread: Overdrive??

The biggest problem for the Perentie gearing is getting to 100 KPH, they are no race car off the mark but will plod along all day. Rather than spending money on gearing, you'll get better results spending dollars on a turbocharger conversion on the engine.

KLR at South Windsor, now do it as a routine conversion.

I recently travelled to Pucka/Corowa in the Perentie (w/LT95).

Further expanding JDNSW's suggestion above re tyre size, I used 255/85 16 tyres (abt 33") on D1 rims. These raised the gearing quite usefully (even makes the speedo read more normally).

The limiting factors for comfort, as JD points out, are wind, canvas & road noise.

Overall fuel consumption averaged about 10.2 l per 100km.

BTW the Perentie has the after market KLR turbo which enables the larger tyres to be used without fuss. The exhaust modifcations for the turbo included greater clearance on the rear lhs tyre.

It may be of interest to be aware that in practical terms the use of 255/85 16 tyres raises the gearing a little too high on a standard Deefer with 300tdi and R380 (and that's how we happened to have these tyres and wheels "in stock" when the Perentie arrived).

And to forestall any of the usual "you can't do that" nay-sayers around, here's a pic showing that 255/85 16s fit well on the Perentie. They fit without any chassis or hanger rubbing and even in the spare wheel space.

That being said, I've driven Arternune's (formerly Spudboy's) Perentie with standard gearbox, engine and tyres at 100Km/h over not too long of a distance. It did it quite happily. The biggest problem was the noise of rushing air making it difficult to hold a conversation.

Unless you are going a long, long way, very quickly, I wouldn't worry too much about gearing.

The transfer gearing can be swapped and is different on the RFSV models. Any RFSV owners fitting a turbo and wanting to swap for a set of taller gears - let me know....

Feeling game?
