Sitec's 101..

I see what you mean, but I think you can get away with a much smaller air cleaner than the one you mention - it is huge - about the same size we use on our 2000HP KTTA50's - although we use 2 on those, they still flow 1000HP each, so that would be huge overkill for 400HP. As Sitec mentioned,the stock 101 cleaner is big for the size of the original engine, and is the same size as a unit on the smaller HP 6B's, so should flow fine for 240HP he is looking at. Without doing the maths on it, I would be happy to give it a whirl at 400HP to see if it would work - I think it would come close.

I'm going through the same with my rangie. Looking for an aircleaner that can do ~500CFM while still filtering and fitting under the bonnet.

The Donaldson ratings are very conservative, worst pressure drop they list for rated flow is 10inH20 which is ~2.4% of an atmosphere. But their filters do allow to collect several kg of dirt and keep working.

I fitted some service indicators to the air filters on our farm tractors, as at the time they were working in extremely dusty conditions and the indicators helped us to know when the air cleaners needed clearing .

If there is any concern with enough air not drawing through the air filter you could watch and see if these indicators triggered as they stay on until reset.

I run a Donaldson informer restriction gauge. Great peace of mind. I'm pulling ~5kPa at the moment which is twice what a clean Donaldson filter would be rated at.

Wow.. Spend an arvo in the workshop and miss out on all the action! 400hp 101.... That would be a hoot!!! I think 240hp will do what I need to do... (for now!! :D). I'd have to change the Bosch VE pump out for the large In Line unit if I want big power..
Anyway, I've just got back from a ten min test drive which took a few hours as it went so well, and here's a pic of my 'updated' speedo.... Yup, it will do 110kph, easily! The jump from 3rd to 4th is huge but it pulls it! I knew it'd be overkill but am surprised how drivable its made it. You now use 1st and 2nd, do all your work in third, and select 4th on the freeway. I was getting some very funny looks as I barrelled down the freeway at 110kph! Wouldn't take much weight to slow it down tho! Incidentally, where do people's temp gauges run? Mine is better now there's more air moving thru it but it still likes to climb to that little red line when working.... :)

You need to get a ratio box bade up to correct your speedo now.
110kmph! 80kmph is fast enough for me in the 101.

Might be tempted to change the diff ratio's in the other 101 though.

The VE in the 4BT can produce enough fuel for 300hp. I'm sure the VE in the 6BT wouldn't have any problems providing enough fuel for 400hp.

I made a typo in the 2,500rpm 400hp figures. I'm correcting them now.

as for temp..mine would just go a wee bit higher when worked but hardly noticable.

never saw it redline.

Easier than that. If you have an older local auto instrument technician he will have a cable turn meter. You disconnect the speedo, plug in the cable turn meter and drive up and back a number of times over his measured mile/kilometre.
Have someone else taking the readings and average them. This will give the number of turns and he can change the gears inside the speedometer head. I had a speedo converted from 4.7: to 3.5:1 (Ford 9") in my Series in 1975. Started off with a Range Rover speedometer as the Series might have "got off the clock". The number of turns is usually at the bottom of the speedo - 2 door RR with 205s is 720 per kilometre.
Simon, it's the number almost under the Cold Start warning light in your dash photo.

Older techs were doing it all the time for taxis, local Highway Patrol cars, etc.
Today its mostly restored bike speedometers they rebuild that get this treatment.

I'll jump that hurdle after the diesel and LT230 go in.. I'm hoping one of the coloured interchangeable speedo drives will bring a Defender speedo somewhere near. :)
