Default 1.4 TDI tuning/info

Hello,

Just bought a 2004 Polo 1.4 TDi .

This is a 3 cylinder engine (1422 cc) , 55Kw (75 HP) , I believe this is PD injection.

What type of turbo is stock on this engine? Is it a regular GT1544 or a VNT?
Full boost is at 2200 rpm , looks like a non-VNT to me.

What tuning options are there for this engine (besides a chip/box) ?
What's the max (reliable) power this engine can make?

thanks,
jaco

I guess it would be pretty reliable if it's a PD130 just with one cylinder less

In that case, 140-150 hp without any internal mods should work.

It's more like a PD100 with 1 cilinder less.
The rpm's were the power is is very small.
With good chip it gets better.

With GT1749V or something you can make 120/130 hp with stonger clutch.
The it's a pretty fast car :-)

Hi Johan, do you have some info about which clutch to go for? Do you know why they took such weak one? if they kept the PD100 there would be zero problems, but it seems even with moderate torque it slips in the higer gears when the turbo efficiency peaks :2200-2500rpm

Your car is equipped with WG Turbo, to swap in a VNT it needs a little more to do. To change to a VNT turbo you can use the device from Audi A2, 1.4l 90hp, and use basic mapping also from this car. Unfortunately the Audi Turbo is a kkk device so you cant do the easy compressor Upgrade with Garrett parts like with a Garrett turbo. I was searching for bigger compressor for the Audi Turbo but couldnt find until now. Anyway you should be able to see about 110hp with the conversion to the Audi device plus chiptuning.
You can also use PD Injectors from ASZ or ARL for further gain.

I'd just go for a gt1749v or kp39a and cut the 4th runner off the manidolf, other DP flange and it's done..

I know, thats the point.. use the base file you mentioned..

you can use 90hp WG turbo, which will also flow 20hp more, but spoolup is with the tiny WG oem turbo already at 2000 rpm.

The car was a VW Polo 75hp version, engine code: AMF

It suprised me that the oem file spiked already 2300mbar while requested was around 2090mbar..



NOTE: MAP and RPM are switched on the axic by axident..

Dawes Device Boost Controller could help to clean up such spiking, isnt it?

A remap too.. as you see the modded log almost has no spiking I first tought there was something wrong with the actuator/N75, but when just spending 5 minuts with the N75 map it didn't spike 50mbar..

The oem file in that car was really one of the ugliest I've ever seen.. it spikes, car was slow.. All of the duration maps had antoher size ..
