[UPDATED] The HPFP Upgrade Thread. (THE APR, AWE, KMD, Autotech, compared!)

[ataylor]

Wasn't going to put it into the old pump. Already have a new one from Audi.

Is there still no place to buy a new pump for less than ~$1k after all these years?

[vce1232000]

Sum APR dealers will sell for $800.00 new . No Xchange

Pretty sure he meant upgraded pump. Either way, that's a great price from JHM.

Pretty sure john@ HPFP sells pumps for $750. Brand new, upgraded. Fancy shenanigans and all.

I've been running Johns stgII pump now for roughly 25,000+ miles with no issues so far if that helps?

I've run a stage 1 HPFPupgrade pump for over 30k miles with no issues.

Edit: Vizi I don't think you can claim longest running build with no issues anymore. I'm roughly 31k miles post build and my biggest issue is burning a little oil due to the larger piston-to-wall clearances required by my JE pistons.

True that. Good to see another person is running with virtually no issues......

I ran my APR pump for 40k with no problems until the follower failed

[mec]

I've got you all beat! 44k on my stage 1 hpfp upgrade pump, never skipped a beat

And the funny thing is most don't trust his workmanship for some reason. But the ones with the most to lose use his pumps!

Yeah, CF's just suck! That's why I change mine every 10k regardless but unfortunately I know it can break 100 miles into its use.

Black Friday deals coming up...... If you can wait that long.....

[seal66]

My stage 2 HPFP has lasted two Audi's and over 50k miles.... So got all of you beat ha ha ga

[baldy]

Ok, to be fair, my Autotech lasted over 65,000 miles. So maybe I have you all beat, but just can't help to wonder if there is a better option I guess. The main design feature of the HPFP Upgrade, Corksport, LOBA, APR (CP-E) which I think would help with longevity of the cam followers is the button retainer. I never had any fuel leaking through the seal, etc. So on that note, it has been reliable and I'm not complaining. It's just if there is a better option, now would be the time to upgrade.

I guess I'll see what Black Friday brings.

So...reviving this thread for a question:


My hpfp has a crack across the connector, and I was looking up the part number via ECS. IIRC, my car originally came with Rev K, but I noticed the latest OEM rev is M (06F127025M vs 06F127025K). Does anyone know what the difference is?

GAP tells me this same hpfp is used up to the 2015 TTS (265 hp, 258 lb-ft -- essentially B7 2.0T Stage 1). APR Stage 1 for that car says it requires no hardware, and it's somewhere in the ballpark of >350 hp and 350 lb-ft. Stage 2 also doesn't have any additional hpfp updates. Could the update been to stronger internals?

[Flygman]

Will a upgraded HPFP do any good on a K03 with a turbo-back exhuast?

Unless your car is tuned, I don't think so. Someone may correct me but I think stock fueling vs upgraded won't make a difference in a stock car.

Yeah that makes sense, but can more power be gained from tuning a K03 with an upgraded HPFP?

Yes, a stage 2+ tune will require a test pipe or HFC, intake, and a fuel pump upgrade

Would an RS4 HPFP be equivalent or better than these upgrades?
I have a K04, S3 injectors, cat-back exhaust, stock HPFP/Cat.
I need a new tune.

Stock hpfp with a k04?? That can't be good, lol.

AFAIK the RS4 has a roller follower. My roller follower is certainty off of an RS4 B7. So I would “guess” the HPFP is incompatible without a bunch of modification.

Yeah current bs tune is pulling 20-30 degrees total timing at 45% load. Timing decreases when load goes up. Its requesting only 1600mbar at it's peak. I think I'm going GIAC because it's 91 and easiest of all for smog.

[arankaspar1]

As low as 250mbar requested boost when actual is 1170 and the waste gate isn't opening.
