20 Autotech, 17 APR, 8 Loba

thats the standings so far

Autotech is cheaper, APR has been around longer, so numerical comparisons don't mean that much. :smiley:


Have you run all three at one time or another John? For anyone who wants to go Stg 2+ but has not yet the APR is struggling in my eyes as Loba pump has all benefits and is cheaper and Autotech for anyone on a tight budget is quite a lot cheaper

You are right. The Loba pump also has other benefits as the tip of the piston is larger and so will be less prone to wearing the inside of the cam follower, plus it is advertised as rated to 150 bar tested, whereas the APR pump is tested at 140bar IIRC.
For me the Loba pump is clearly the better value pump and the fact that it looks to be a higher specification than the APR pump says to me that anyone buying the APR one from now one either doesn't know about the Loba pump or is brand loyal to a fault.

Great summary John

If you can afford it get a Loba, if you are on a budget get used Autotech internals (whilst you are saving up for the Loba  :grin:)

APR is tested to 150 bar as the stage 3 turbo kit runs a 150bar FPRV.

Both the contact points onto the follower are the same on both pumps.  APR on the left, Loba on the right:





Loba is still the winner on price, but there isn't anything in it between that and the APR in terms of performance and quality.

Alex, on a k04 car with S3 injectors, is there any benefit in increasing the pressure from 130bar to say 140bar if the HPFP allows it or there are other limitations (like maxxed out turbo, injectors...) that won't allow the power/torque to go up ?

Only if the injectors are maxed out at 130 bar.  The extra pressure will allow more fuel.  APR run 460 odd bhp on the S3 injectors at 150 bar.

This is news to me. The last time I saw the fuel pump it had a smaller head on the piston which didn't have the chamfer. Also the last time I heard 140bar was what they tested at. Just looked on their website and looks like things have moved on. Thanks for the update Alex. Looks like the difference is just price point then. :happy2:

On a side note, It must also be fairly recently that APR started using the 150bar FPRV......probably since the stage 3 golf R development was completed. I know they have changed a few things like going back to S3/R injectors and removed the need for the LPFP as they had a few issues with the controller, specifically voltage related.

there doesn't seem to be much in it between the APR and LOBA pump except price, lets get a few miles on these LOBA pumps and see how they fair. If alls good it will be good to have a choice and maybe it will trigger APR into doing something about their price :happy2:

You can get 155 bar FPRV's from America, could run massive fuel pressure then on a LOBA or APR pump.

You could run a LOBA LO400 with standard injectors and no need to worry about bigger injectors..

I am currently fitting a BWJ K04 engine in my Mk1 Golf Gti, I am thinking about buying a Loba pump, is there any advantage of fitting an RS4 fuel valve with this or does it come with one?

Also, my current lift pump is good for 10 Bar and I have an adjustable fuel pressure regulator, will this be ok or should I get a Genuine fuel filter with the built in Regulator?

Loba pump doesn't come with the rs4 valve, but it is worth fitting one.

As long as you have a good fuel return then using the regulator will work.

Thanks for the info Alex!

How do you mean a good fuel return? I'm using AN-6 hoses for supply and return lines.
