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

Up the boost and wind the diesel pump up andy,if it has the capability,if it has an ECU look into chipping

The new VAG engines are all electronically controlled from the ECU, meaning you cant manually wind the boost up.

A chip is the only option

junk

Is it a 1.9 td or a 2.0 hdi ? Both can be tuned for more power .

Your right, there's not much you can do to a n/a diesel engine the only thing you could do to improve performance is to fit extractors and a better exhaust system.

Fitting extractors and a better exhaust makes a very noticeable improvement, quicker off the spot etc. I know on LR Defenders they have large bore side exit exhausts, but most are turbo'd except the 90's and army n/a diesels

its a 2.0l hdi gl

Lund, what do you mean by "extractors"?

you are in luck with the hdi , you can remap them or plug in a tunning box . this will give you another 30-50 bhp ! !

Oh sorry, err extractors are like steel tubes welded to a header plate that bolts to the
head. A manifold basically! The factory exhaust manifolds are sometimes steel tube, but mostly cast iron, can you get different manifolds for it?

With the exhaust: Increasing the diameter will help it breathe, but don't go over 2" (5cm) as this will INCREASE backpressure due to gasflow stagnation. Aim for 1.75" or 44mm Should be enough, I think.

There isnt really much, that you can do to a n/a diesel, without huge modifications, I say improve gas flow and modifications to the breathing: Snorkel is good Intercooler??

Make it as light as possible

On another note, how often do you go offroading?

Diesel tuning for me is simply

99BHP standard..

145-150BHP tuned
MAFAM
ITG panel Filter
Boost increase of 3-4psi
De-Cat
FMIC
Chipped

ok, so were do i go for a new ecu ? please

here andy, hope your engine is listed there. If not try superchips.co.uk
