What are the benefits?

Carl :happy2:


being able to match requested fuel pressure  :wink:

this will then mean that car can run at full capacity regardless of it's state of tune  :happy2:

Lastly - I can't believe you're going for that APR propeganda and dismissing Carl's advice, I'm sure he doesn't care what pump you fit, he isn't getting the profit off it. Sure Autotech might have had a few bad uns early on, but that statement put out by JKM was a bit too far if you ask me. Autotech 100% addressed the issue.


....Wrong! If you read my earlier post* you'll see that I am taking JKM's advice and it's nothing to do with "APR propoganda" - In fact, to date, I have never read anything written by APR about their pump. [*= unless it's the other thread where HPFP's are being discussed today]

Robin you can disagree with me all you like but the fact is that even with the car in it's stock guise is struggles to keep requested rail pressure, data logs prove this categorically.


....I don't dispute your knowledge of such things but it leaves me questioning why JKM haven't advised me to fit an aftermarket HPFP, especially as they have developed my car from stock.

Let me add my penny worth...

Anything that removes a restriction improves the "cumulative effect" of all the other running components.  Remapped cars typically have a slight plateau in their bhp profile - typically between 3700-4500 rpm. 

It's down to sufficient fuel being available at the correct pressure...

Come on RR - you know you want to have a HPFP?  :party:

If Autotech sent JKM 1000 pumps with a note saying what they did to ensure there would never be another alleged 'duff' one again and every one was 100% ok, do you think they'd start selling them again?

If the answer is no, then a cynical person may think they'd been taken in by another agenda. Of course JKM are better than that, but it's happened with others...

Dirty tactics and rumour spreading on the internet - the cheap tricks of someone who can't admit they went about something the wrong way.

As I said in the other thread I have had autotech internals in mine for over 40k with no issues

So they obviously did something right first time round. 

Carl :happy2: 
it isnt an on going thing. there was only a bad batch, of which the fault was rectified.

jonny has had them on both his cars and they managed to keep up with his required fueling which is pretty good testement to the internals.

  I have them on mine as have many many others in Uk and america with zero problems.

....What 3700-4500 rpm bhp plateau? : -



I'm doing all I can not to buy even more mods. So perhaps I should stop posting on this site.

Let's see that car's fuel rail requested and actual pressure before going any further...

....But he said "in their bhp profile". Fair enough if he meant power, ie torque.

Come on Robin....don't try to wriggle out of this...   accept it gracefully.

You know full well I don't know my "fingers from my thumbs" when it comes to cars.  :P

@ Mo:

You wrote "bhp" so I looked at my bhp plot - Very simple. In retrospect you made a mistake and I made the mistake of not spotting it. No wriggling involved.

Anyway, we all learn from our mistakes.  :happy2:
