HPFP's - Why did you choose yours?

[SteveP]

Just interested to know why people have chosen either the internals kits (like Autotech, KMD, etc) or a fully built APR pump?

Is the APR hype really worth the difference or is a properly fitted internals kits just as good?

opens a cold tinny and gets a ring side seat.

I am hoping for a clean fight

I chose autotech as I wanted to fit myself and it was not a apply to the bank for a loan amount of money thanks to PDT 

Edit also I would like to see the internals of a Apr to see the difference as I bet most the price comes from it being a new pump apart from the new internals.!!!

money no object id go apr as it doesnt have the stepped design (which according to JKM is the cause of the seals failing on the autotech pumps).  

However at the time i thought it was just another overpriced APR product and i went for autotech HPFPs as more guys were using it than any other

[GTIjames]

I chose apr on my old ed30 purely for peace of mind, read a few too many stories of rebuilt ones going wrong and after spending £22k on the car plus another few grand plus the rest  on mods  whats another few hundred for a quality piece, tried and tested

Is this question for when you choose a pump for a MK5???

APR all the way.  Spend the money, get the performance.

This is all from my experiences using, fitting and repairing different pumps.

KMD - I have had loads of failures that have cost lots of money to fit.  When they had the coating, they would sieze, break the follower and fook the cam.  I hear they are better now they have done away with the coating, but their customer support was a joke.

Autotech - Not had a problem with these apart from the way they can allow fuel to pass through the seal and mix with the oil.  Bad news for rings, bores and bearings.  Personally, I have only felt the horrible 5.5k flat spot with the autotech pumps.

APR - fully built, tested and ready to go, great customer support too.  Piston design wont put pressure on the seals and there is a larger surface area on the follow which seams to cause less wear on the followers.  I have APR's fitted to loads of cars inc X-bows which are abused for hours on track days and are still perfect.  Ive not had any pressure drops or flat spots on the cars ive fitted the pump to.

Yes for pump's for the Mk5 or anything TFSI based.

Interesting point about the 5.5k flat spot

I chose the APR as it was the only tried and tested design, my decision in going for the APR was made stronger as someone just had a failure on the forum at the time from one of the other manufacturers, at the end of the day there are not many failures on the autotechs probably mainly due to fitting technique, but i decided to pay double and not take the risk ! and id do the same again, as the resale value is very good

APR clearly the way to go if yo can afford but i hear from well respected sources that the only time Autotech failed was when not fitted properly ie not sealed with some clean engine oil, if the person fitting it has the competence eg PDT then should be worry free as long as keep checking cam follower and smelling dipstick

APR for me.

Largely for the reasons above but also because I went to the US and bought one there.

I fixed it for you.

APR all the way.

I had Autotech internals in mine. On Stage 2 I never got more than 256bhp with them. Swapped to an APR pump and the power went up to 270bhp. Nothing else changed on the car and logging wise the Autotech was apparently making the requested rail pressure. However as the autotechs started to fail I had the APR put on and wish I had done it in the first place.

Autotechs will fail over time. I installed mine myself and they lasted 50k miles ( so obviously no issues with the install ) the problem is the stepped piston and not the competence of the installer as long as they know what they are doing. Or have a hotline to a man that does 

As the saying goes. Buy cheap buy twice.

I've got an APR pump. I bought if for the reliability issues and and fact that I can sell on as a complete unit for decent money when I'm done.

HOWEVER I got the flat spot issue at 5500rpm, which appeared not long after the pump was fitted.
