Autotech vs APR HPFP

[danishmkvgti]

Also the APR pump only provides 125 bar not the 130 bar fuel pressure that most software such as Revo demands on stg2+.

Sorry Dave thats wrong.

I've got logs of my Car on Stage 2+ with the APR Pump and it quite happily meets the requested 130bar.

Sorry, my mistake. I was going off logs from 2 cars with APR pumps and software, its the software that requests 125bar, not the capability of the pump.

Sorry again, i have APR K04 SW atm and it requests 130 bar and gets 130 bar from my APR pump. What APR SW are the logs from? stage? K03?

Stage2+ equivalent k03 cars.

I know this post is old, but just wanted to clarify........other than the price and safety of the APR, does it have any proven performance gains over the Autotech?

I have nothing against the APR pump (except the price), but I would get Autotech Internals fitted by a professional and happily see 50K miles from it (which is about 30K more than im likely to do with it in 5 years of ownership) 

This way the other £350 can be used to buy a Twintake/ITG etc

Get autotech one it's a lot cheaper and it's not hard to fit at all.

Fitted my own one and I'm no mechanic just follow the instructions

Wether or not this was my car is hard to tell but.

With the Autotech fitted and meeting the requested 129.99bar my car produced on it's best run 258bhp on Stage 2

With the APR fitted on Stage 2 i got 270bhp.

They both produce the same amount of fuel in the end. I had an autotech, then bought an APR, then bought another APR
The main concern with the autotech is the fact it has a stepped piston, which potentially in theory causes extra pressure on the seal, which could end up causing your fuel to mix in with your oil. Theres only ever been a few cases of this, and there have been thousands of them sold, so people go for the APR simply for piece of mind. although the problem could have been causes by bad assembly?

The war of the HPFP's has been waging for years.

If they were both the same price, which would you buy?

I had heard that Autotech had addressed the issue in design that made their internals susceptible to failure?


I'm sursprised no one has considered KMD, they are supposed to be excellent..........

I have to vote APR.  I am now running an APR pump after my HPFP with Autotech internals failed. Luckily I was always wary of this happening so caught it before any real damage was done to the engine but the oil smelled like it was 50% fuel.

How did you keep an eye on these mate?  I am cosidering get Autotech internals from W8, but leaving the car on the stage 2 software.

[vRS Carl]

Check your oil regularly Lee.

If it smells like petrol or indeed the level on the dipstick starts to rise, you have a problem. Mine lasted about 50k miles before it gave in and i installed them myself. Others have had them go far quicker.

I was regularly sniffing my dipstick!!

....Well I suppose that's better than sniffing someone else's dipstick!
