Performance Improvement Suggestions

Pressure wash the chassis and crevases, you'll easly lose a couple of kgs of dirt. Fit K+N airfilter, and if you don't have a snorkel fitted, drill 1" holes in the plastic air box lid. (cheap boy racer trick!)
If you have a snorkel fitted, disconnected at the air filter input. That'll give you a couple of BHP back.

Pressure washing the chassis I agree with.....

K&N filter...  main advantage is that you can just wash it and re-oil rather than having to buy a new one.  IMHO a filter will not make the + 4 bhp that most manufactures seem to claim!! (unless the air box design is very bad!!)

Plastic air box on a Defender  :? (.... well except for the TD5)
Usually the holes are drilled in the bottom of the air box - i.e. pre filter - most cars (i.e. 99%) take the feed from above the filter, so if you drill holes in the top section you would be sucking in dirty air  :shock:

Main difference is increased induction roar... which most chav's seem to think gives their cars at least 50 bhp..... :roll:


If you want more from a Tdi.... (IMHO)

The next stage would be a hybrid turbo, better exhaust, bigger intercooler (possibly), a gas flowed head, and if you still want more then a propane or LPG kit.

The most I know of someone getting from a 200Tdi is 198bhp and 360 ftlb of torque - compared to 107 bhp in a Defender (111bhp in Disco and Range Rover) and 198 ftlb of torque as standard.... but the engine needed rebuilding every 20,000.... and it was 'very' modified!!!

specs,pics anything, i wanna see that  :twisted:  :twisted:  :twisted:

The spec... haven't got any pics (was built quite a few years ago)

Copy of my email:

We blueprinted the engine, had our own cam ground, balanced the bottom end, changed the pump settings, had a custom hybrid watercooled turbo built, bigger valves in the head which was ported and gasflowed, We balanced and equalised the combustion chambers in the pistons, fitted total seal rings and a metal ring combustion seal around the combustion area.
We had it set up with adjustable boost and fuelling from inside the cab, we had temperature probes placed in key areas around the engine to monitor the temps.
There were loads of little odds and sods changes to get the last ounce out of it and raise the reliability.  

The end result was an engine that was capable of 198 BHP with 360 ft lbs of torque in ambient temperatures of 30c degrees. The bores would last approx 20,000 miles before they needed reboring.
The reliabilty was ok. The performance was amazing, it would happily devour a 4.5 V8 up to around 100 MPH. It would then run out of revs. The downside was that more power meant more emmissions. It was not exactly ozone friendly!

We could run up to 2.5 bar boost. I don't have a pictures, but from the outside it didnt look that different other than silicone hoses and a different breather system and bigger aircleaner.
We also had to modify the flywheel to take a Cosworth 500 BHP clutch, it spat the standard one out the first time we turned the power on.

mikee are you thinking what i'm thinking?
20000 miles is a lot of off roading and a lot of fun eh
