Hpfp upgrade

[sub39h]

I have asked this before, but hypothetically if the Autotech and APR pumps each cost exactly the same, which would you buy?

That's as irrelevant as me asking if you'd have still bought an APR if it was £5000.

They don't cost the same, and in my opinion the APR does not do enough to mitigate the risk to justify it's price. Hence I went for an Autotech.

I would like to know how the conclusion was reached that the fuel pump was responsible for the fire.

The fuel pump leaked fuel into the sump which several people have reported but not with the same results.

This resulted in, no particular order, a hole in the side of the block which allowed allowed that mixture to hit the cat.

I find the Apr to give a more constant fuel pressure hold on wot.  The autotech never seems to be able to hold quite as much pressure and fluctuates the pressure more.

Fuel mixing into the oil will always destroy an engine.  Even if the oil is drained, the fuel will have caused damage to the bearings and the bore which reduces the life of the engine.

Autotech internals do the job, but its always best to fit them to a new pump.

I had a standard fuel pump fail on me let alone one with uprated internals. Would like to think it I caught it early drained oil washed through with fresh oil once warmed up. Now running some good stuff. Think it has killed my k03 tho oil leaks when parked on a curb leaning down on the side of the downpipe. And get a nice big puff of smoke when going up a hill or once warm when you hoot it. Alex you think anything else could be damaged?

....It's because they don't cost the same that I suggested that you IMAGINE (I'm sure you know what "hypothetically" means) that they do cost the same, that you hadn't chosen which pump yet, and therefore which would you choose?

If you prefer, it's the same as telling you that someone is generously offering you the choice of either HPFP as a gift - Which would you prefer to have?

You may still choose the Autotech pump - I know which you have chosen but wonder if your choice (and anyone else's choice) would be the same IF they both cost exactly the same.

I'm afraid that if you don't see the point of this question, then there is no point me trying to explain any further   [It's a genuine question and not meant to be rude or unfriendly towards you].

I'm not denying that the APR probably carries with it less risk than an Autotech. In your hypothetical situation it would be the one to have.

But in the real world, in my opinion, there is not enough of a decrease in risk to justify it's price. PDT have sold hundreds of Autotechs without a single failure. As i've mentioned before if I were to crunch the numbers I'm sure that would yield a mathematically significant result more powerful than the results we require before deciding which drugs to give people (!)

[56OctyVRS]

Looking at both arguments for the APR and the Autotech. I went with the Autotech purely because I did not feel that the APR pump commanded such a high price for the same part. Both are designed differently but in real world driving there would be no on the difference in car performance. Like every part that is uprated you run the risk of failure as more stress is applied.That was also a reason why I chose the Autotech internals as it uses the oe spring. I know the APR uses much stronger spring rate and can cause issues with the cam follower wearing quicker. I also belive that is the only reason why the APR pumps seem to hold a slighlty higher rail pressure as the spring pushes the pump out quicker and gives slighlty more force to push the fuel through.

So have Jabbasport, when I asked about which to go for they said "Autotech", they told me they do the same job as the APR and having fitted plenty themselves with no failures they are happy to recommend them (Jabbaluke ran one in his ED30).

I don't particularly like APR tho so would be biased on my own choice (Autotech), and the high price of APR, but ETTO

Everyone has their own opinion but as for price it's a no brainier surely.

The most reliable way of doing an Autotech internal job is to fit to a new pump right.
New pump £150ish i
New internals £290
Total £440 plus paying someone to fit them.

APR rebuild pump £478 already built and ready to fit.

Sorry but without the fitting charge for the Autotech the APR deal at £38 difference I can only see one way to go.
APR here we come.

Except for £478 you either have to buy a new pump, £150, or have your car off the road for 2 weeks.

If you choose to buy a new one your old one could only be worth £50 or so, so it's more like £138 more, or massive inconvenience.

I brought my Autotech to vRSAlex, rolled out 30mins later with Autotech internals and a new cam follower. No inconvenience at all.

Jabbasport stated rebuild of existing pump with Autotech internals was fine (It gets cleaned before internals fitted), no need to spend another £150 on a new pump, so its gonna cost you £285 plus half hour labour  , believe thats a fair bit less than £478 plus half hour labour (and car not off road for 2 weeks)  

[Marshall]

Sorry but the 2 weeks downtime isn't true.
If I removed mine today and sent it next day delivery APR would send my new one tomorrow  next day delivery so 2 days downtime.

The other option would be when ordering pay a refundable surcharge when they receive your old pump back you get your surcharge back.
This make zero downtime so still seems the only way to go IMHO.

You still can't compare a new pump with Autotech internals to a refurbished APR. Compare like for like and I still feel it's not worth it.

[Marshall]

Each to their own and I know which way I'm going.
If we were all the same it would be a boring world.

....Agreed 

And no regrets about the one I chose and that it cost me more money which I could have spent elsewhere. I can feel the difference the aftermarket HPFP makes.
