Thread: 300 Tdi - Bit More Go

Wind up the Fuel pump. (only do this with a EGT gauge), There is a great page/tutorial on here somewhere, just can't find it at the moment.

What ever you do the EGT must not go above 700 degrees C. I had mine up pretty high. Over Chrissie on the Long Hill up the monaro hwy from Cann River, with the camper was nudging 700 b4 backing off. Mind you I was sitting close to 90kmh the most of the way.

Is your tdi300 a electronic diesel control or done by the good old fashioned cable. If its cable control I can tell you what I did to mine and which gave it a lift in performance. Also is it auto or manual. At 280000 kms I would be a bit careful if its had no motor work.

there was an interesting article on diesel gas in the May edition of Overlander - the most detailed description I've seen of the technology out of all such mag articles in the last year. It had an amazing graph of the performance increase on a 300Tdi Defender - almost double the HP and torque! The effect on an electronically-controlled TD is much less but still significant...

By all means get a compression test, but I know of a 200Tdi with 500K k on the original motor, so 280K k isn't too high for some sensible performance mods - many of which don't need to result in much more stress on the motor (e.g. remove centre muffler and fit ECU-controlled diesel gas from a respected supplier - and then try to avoid using all of the increased power all of the time!) unless you flog the vehicle of course...

Hi Feraldisco;

Any chance you can Scan the article and post it up in Aulro ?

I got a proper disel tune done i went the 'FULL' tune which involved pump mods which were mechanical rather then just little pump tweaks. I would suggest new injectors whould make a big difference without any other mods to start with. my 300tdi went in to the tune with 33kw @ the wheels and came out with 50.1 @ the wheels and OMG what a difference!! 4th gear (mine is an auto) pulls away now!! unfortunaly money talks! save some cash and get it done by a pro i had my pump tweaks ok but did a head gasket mostly due to age 265km. so i was up for a full head rebuild and then the tune so it cost me more in the long run...
