All Things Mk5 > Performance Modifications
Has anyone changed the LPFP at Stage 2+?
berg:
might put the ttrs lpfp in then and the apr hpfp at same time and get rid of the autotech internals

only way I can think of it is like maybe upgrading your washer pump :signLOL:
he couldn't guarantee it too me and im no expert but id want too see dyno results and data logs before I buy one....and soon :laugh: I need a new one

Master tech! You mean apprentice.
Variable load pump controlled by its own ecu.
All the logs are in my build thread. Can flow and hold much higher pressure at lower load. Basically gives the hpfp more help allowing it to work under less strain. After fitting I noticed more mid range and top end grunt. Hpfp pressure was also more stable.

How straight forward would this be Alex?? Variable load pump controlled by its own ecu
vRSAlex:
All you need is a pump and a blanking plug when running it in a fwd car. Ive had some cnc plugs made for the job.

Pitty I had not found this out sooner, as I have just fitted an up to date LPFP

I've been looking into this too. What blocks are used to log lpfp actual and requested.
