300tdi need more power

(1/4) > >>

ross501:
i have a 300tdi disco and will be using it for towing need some more power for the hills drops to about 40 and has no power to get up them any suggestions

extreme90:
bigger intercooler, but it will make the engine run alot hotter, expecialy in hot weather, and thats without towing  :shock:

just turning the pump up on its own simply wont be enough to satisfy

either leave it as it is where its reliable, fitt a bigger intercooler but run the risk of running hot

or get a bigger tow vehical

oxymoron:
Hi, I have been running a bigger intercooler for the last 120,000 miles.
You just increse the fuelling when the turbo is on boost via the capsule on top of the injector pump.
Make sure you are getting full throttle travel, I back mine of by about 5% for the rev test on the mot,and it makes it flat as a pancake.
On some long motorway hills it will outpull the newer TD5 discovery,not bad for 185,000 miles!

extreme90:
just turning the fueling up on the diaphram is a waste of time and a waste of money on th intercooler
now dont take it the wrong way but u think its fast, put it along side mine or someone elses where its tweaked properly, u wont keep up  :roll:

if your turning the diaphram and leaving the smoke screw, your not getting enough fuel vs the increase amount of air thats entering the cylinders due to it being denser as its cooler becouse of the intercooler

sorry, but your not benifiting

towing it doesnt matter if your doing 40 up a hill, your towing  :roll:
youve got to expect to drop down the box
just like anything else, td5's are the same

we tow a boat all round the country
fully laden its 1.7t

to try and make the 300 disco go better i turned the pump, didnt make a differenct, still the same

if i tow it with my 90, pumping out around 150bhp if not more, it still drops down the box even with all that torque

and it gets too hot for liking and thats with the 8274 off the front for better cooling  :shock:
and also a big pacet fan cooling it

its just a no win for towing

only way to fly up hills is with a dirty big land bruiser,nothing can touch them for towing

thats my opinion and am sticking to it  :roll:

feel free to rant at moan as you please  :wink:
