Hi Rainsey, the thermo fan is 240mm dia (ebay) and mounted on top of the intercooler, when BD were fitting the engine I asked for a larger air scoop (the truck was originally a 4.5 petrol, no scoop) so the fan fits nicely inside the scoop housing with enough space for air flow for normal driving. Living on the south coast, Shoalhaven, but travelling whenever possible.
regards
Peter
Your speedo and odo should be different.Originally Posted by rainsey
The reason is that the manuf tries to set the Odo as accurate within +/- x%
But, by ADR requirement the Speedo is not allowed to underread IE has to be accurate within -0% to +10% of reading + 4KPH
Bottom line is over a given distance ex factory ratios and tyres the Odo is normally very close and the Speedo overreads by around 4 to 5 KPH
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
Well bugger me.. and here I have been thinking I have some weird problem. Regardless, the signal is from the same source so if the source is changed, both odometer and speedo change .... I assume!
Ill take note on Monday when I am cursing p the freeway what my Speedo reads when I am on 110km. Pretty sure it is out but more that 5KPH.
Kindest regards

Sweet, thanks for that info. I am up at Gosford North of Sydney. Periodically cruise down your way so will drop you a PM next time Im heading that way. Likewise drop me a line if you are up this way.
Cheers

At 110 KPH actual (with factory ratios and tyres) to comply with ADRs your Speedo should indicate somewhere between between 110 and 125 KPH
IE... 110 (not allowed to underread) and 125 KPH (allowed to overread by 4 KPH plus 10% of actual speed so another 11 KPH).
As you say, quite correctly, the speedo and the Odo have the same sensor but are two seperate 'displays' and the two displays are set almost always set up slightly differently at the factory.
If you change your tyres by say 7% in size it will affect both Speedo and Odo the same amount because, as you say, the sensor is common to both
Sama sama if you change ratios.
Lots of people think that the Speedo and Odo have the same error IE they check speed against GPS and if it is say 10% out then the Odo as out 10% well.
On rare occasions it will be... but... it is much more common for the Speedo to overread the Odo.
Disclaimer - the above is not applicable to mechanical speedos (cable driven) or electronic Speedos prior to the ADR changes

Hey guys, not sure where else to ask these sort of questions .. sorry...
Does anyone know of a twin turbo setup on the 6.5 ?

Guys, my conversion leaves BD on Monday heading for home. I would like to get some feedback pls on the following.
1) what brand and grade of engine oil are you using and also are you using any additives?
2) I have a Donaldson air filter Assyr fitted and have had zero luck finding a k&n equivalent - checked websites and sent k&n a note- so has anyone got a recommendation? I noticed a huge improvement in using the in over the factory Nissan paper unit in the 2.8. I will supply the part number later, but mine is the optimiser n/a crate engine, not the turbo version.
3) do any of you use either a 'water wetting agent re reduced friction or the waterless system? I am focused on outright performance and not cost.
Are there any things I should be focused on regards good practices for this engine?
Thanks phil
G'day Phil, Please do focus on cooling the new beast down under load IMHO! We've got Yank donks that had original issues already yet we squeeze them into tiny Q's & U's & Yoda's. Some blokes up FNQ have received descent sized oil coolers to solve their experiences, I believe have read ?
