Forums Forums Enthusiast Forums A - Z Autowirral More power from a diesel

Whoops! forgot to add you'll need an aftermarket ECU and get it mapped to sort out the fuels/boost etc.

If an older TD engine is used, or an older diesel with supercharger, chances are it will be mechanical diesel injection, so there wont be an ECU (Fitting an ECU will give water - electric problems)

Jusst need to adjust the fueling and the timing on the diesel pump

Sweet, and yeah, it's a mechanical diesel, no ECU.

Scoob, what's water injection? And how would it benefit the Jeep? Never heard of it before..

water injection sprays a very fine mist of water into the combustion chamber to eliminate detonation. this is mostly used on turbo charged cars like evo, cossie, etc.

they retail for about 350 to 500 i think. do a google and u will find more info

Its a very old fashioned method of gaining performance. Basically its a very fine mish of water sprayed into the induction side of the engine and when the det happens the water turns to steam therefore pushing the piston down harder.

I only have very limited knowledge of water injection but its proven to work.

It has many many advatages such as its free

It may be worth doing some homework to find out about it. I have heard you can make to kit from some simple items (D.I.Y)

water injection does not gain performance.

pretty pointless in a derv as det is not common,

i'd still say turbo as you could make a splash guard for the turbo/manifold as they don't get that hot anyway

True, on a Derv, water injection wont really be of any help

Water injection actually loses you power as you are adding water to the air fuel mix, but it does prevent det so allows you to run more boost which gives you the performance gain - theres a very fine line at the point of where you actually need to start using water injection.

Have you thought about general diesel tuning like a a diesel tuning box.

Personally i think TD is gonna be the best route as when hes off roading he wont be boosting really so cold turbo,then when its time to go home he has more power to get him home faster and his turbo can get as hot as it wants then cos thats him out of water for the day,good idea no, and as for the pic on the last page,Who the hell drives thru 4 ft deep ponds?!

Any idea what turning up the excess fuel will do? He's already got it fed through to a switch, he uses it when the engines cold then flicks it down to save fuel. Then when he wants a few more pounds of torque he'll flick it up again. Works really well atm but what would happen if he turned it higher than it should be?

allot of black smoke

Rich mixture is okay, lean is dangerous. Have you played with the diesel pump timing ?

Lol I know, but will it increase perfomance? Or would it put the engine in danger?

I don't think he's played with the timing at all, I certainly haven't.

if the timing is spot on them this will help the running.

if you over fuel then there is a risk of washing the bores which is bad due to the leaking of feul into the sump by bypassing the piston rings. this is extreme cases tho.

1.7td out of an old cav is what u need imho.

well i have just bought a 2.0l turbo diesl citron belingo van and was lookin in to upgradin the speed, i hink i have the right engine to be sooped up so any ideas any one ?
