Thread: 300 Tdi - Bit More Go

Not a huge amount you can do really.

Wind out the fuel pump and change the intercooler (but they cost a bit) There are also VNT turbo conversions available but they cost even more!

Cheers
Pete.

along with winding out the fuel pump you can mess with the boost pressure setting a little bit by adjusting the wastegate valve rod and then a little tweak on the boost compensator (part of the FIP) will bring it up a little faster.

Jock ;

Within the 300tdi Bosch Pump there are adjustment that can be made to improve the driveabiliy of your Vehicle ,

3 Adjustment

.Eccentric Cone / Diaphram Position
.Stop Screw
.Star Wheel adjustment

before you set out to do any tweeking , Please buy and install a Pyrometer ,don't set about doing any tweeking without being able to monitor how hot things are getting inside your engine ,

Also if engine is slightly down on Power have you checked following;

A) Valve Clearances 0.2 mm on intake and EggZost side

AIR Filter / Fuel Filter replaced etc

C) Intercooler / Turbo Hoses .

If you'd like to obtain a Pyrometer go here

Try this from the past some good info in here , and links , the search button is your freind

Maybe you could replace the exhaust with a 2.5" system strate through i don't know how much power you will gain though
Or you could upgrade the turbo and intercooler, new airfilter, new injectors etc.

CHEERS TIM.

On my Tdi i removed the main muffler and replaced it with a straight thru hot dog muffler , It made a slight difference at spool up

I had gas fitted to my 300tdi. It has a great increase in performance plus around 1000k per tank of diesel. Jim

Safest way to get more go.......tweaking the pump can lead to disaster for some and if you want to go down that track..get a deiso mech to do it....IMO
