so who does them then

See MOB's reply. JBS fit NOS regularly and from what I can gather it goes rather well with diesels. Don't forget their NOS Fabia uses the VAG PD130 engine and I can assure you that it certainly shifts [:O]

NOS in turbo asprirated cars is asking for trouble. NA Diesels (SDI's) are the only diesel where NOS can safely be implimented. The strenth of the NA diesel engine makes it an ideal base engine. But if you want to use it daily, an uprated clutch and gearbox would be essential.

The Mk3 they showed on TopGear was an N/A 1.9D, with an automatic gearbox(to minimise clutch slip)

OK this is a great show of people that have never tried it before, only heard stories...

you cannot put NOS on a diesel!

look at the ways the diesel and petrol motors work. Diesels have NO spark plugs. Petrol does. NOS has to be mixed with fuel as in PETROL!!! Diesels are ignited via compression. Also look at the make up of NOS. dinitrous oxide. or n2o. the nitrogen is there to cool the effects of the BURNING oxygen that was ignited by the burning fuel air mixture. Oxygen is not flammable. But it is an oxidizer. you give it an open flame and it will feed it. Diesel has no open flame compaired to petrol.

You are gonna like this though..

PROPANNE!! propanne does the exact same thing to a diesel but without all the bad side effects. it will lower the temp dramaticlly!! You can do the whole nos thing and buy the kit but fill the bottle with propane! that will give you huge jumps in HP and Torque! try it out and let me know

You are doing seriuos harm to your motor. and PROPANE is cheaper!!!! I don't know about you but do the research! allot of banks diesel trucks do a propane injection system. Better for the enviroment, your motor and your wallet

I've head a lot of interesting stuff on here, but this is just plain ludicrous! Anyone who wants to feed highly flammable propane gas into their cylinder head instead of good old O2 (or N2O, for that matter) needs their heads read. It'll certainly cause a 'bigger bang' in your engine, and no doubt, will result in increased performance from the engine. That is, until the piston rings melt and the head cracks.
