Had my 80 TDi on the rollers today..

My local friendly Rolling Road (http://www.surreyrollingroad.co.uk/) had a small dyno day today so thought I'd take the tank as I'd already had the 540 done.

The 80 is totally standard, with 146k miles apart from an EGR blank, slightly enlarged airbox intake and 4x4" hole in the wheel arch liner to vent the exit of the intercooler.



Quite happy with that, just need to get a bit more from it now!

Bet your happy with that, any pics of the car

[Max M4X WW]

Like the colour of the estate very nice and the saloon is in really good nick to and am not surprised your happy with that and i bet your economy is excellent

[Max M4X WW]

Saloon was a non metallic colour, but a tidy car with 138k. Sold it last month.

The Avant is doing ~49mpg which was 585miles to a tank

Need a bit more power now!

Lovely car Max, ive just picked up one myself, any plans for it? are they a4 mudflaps by the way? heres a pic of mine

[Acidburn]

I used to have one of these but a s2 avant rep titled the chipfat express was a good car till an accident saw me loose confidence in the car.

Good values but with poor torque below 2000rpm

1Z engine have max torque at 2000rpm

What gear he make test?

Now remap it!

[Juggs]

Fair play they look like good results for your mods!
I have the same car and i am kind of curious as to what you done to the airbox, could you gibe me an idea as to what you made bigger?

[Max M4X WW]

Avant above looks nice, but I would say that, it looks near identical to mine!

Mud flaps are specific for the 80 I think, they fit perfectly to the bumper/front wing.

Not sure what gear, probably 3rd or 4th but I didn't ask. In regards to the toque, what could cause this? I think the peak value of 145lb/ft is fine? I have been replacing the N75(?) hoses as they were worn.

The airbox has had the standard feed removed, then I used a bit of pipe from an Octavia 1.8T inlet in place of the standard pipe, it fits over the airbox inlet and I made he hole in the headlight deflector thing about 10mm bigger to take the pipe. The actual hole in the air box is not any bigger but the old pipe wasn't as big as this hole anyway.

Rolling roads are funny things.

I've been told that torque curves especially always peak later on graphs than they actually do when on the road.

110 injectors on the way, will see what happens..

Manufacturers plots are almost allways made by breaking the engine down from redline. Also with higher gears on road you will start to boost earlier than dyno can show, as no-one wants the operator to do a 60sec pull
