CP3 Pump Install Experiments.**Big Picts**

Lol.......just relax!

How's the cp3 pump for über power upgrades? Say for instance a GTB2260VK?

This man's asking the real questions.

 

[Smokin_Joe]

Thank You...

Wow! It's been a while, thanks for asking Joe!!








Yes, ~26k miles, a great cold winter and zero issues.
The pump is awesome and works good. I often forget it's even there, but still get a faint reminder with the gear whine from the feed pump.
In the fall I was running tests, logs, monitoring mileage etc!! No drama, I just drive the car to work now and forget about the pump.
We went on a big family trip a couple weeks after install, pretty remote areas up north with full confidence.
This winter was great for "extreme" testing as the temperature has been colder than normal. I did notice the car starts with less cranks than before. The CP3 pump builds pressure with less rotation than the CP4.
Fuel mileage is no different.
.
Maybe not mentioned in the past, the electric Aux pump is long removed as the CP3 pump I use has its own gear driven feed pump. The in tank lift pump is still there, simply feeding the pump. I also run the 2Microntech "contain flow" filter as a 1micron pre filter, after the factory filter. Not required, but it feels great feeding super polished fuel!!!
My car is bone stock, no tune or other upgrades.
.
These pumps are very plentiful and avaiable in Europe. Dozens of small cars use them.
Thanks for asking!!
Andrew

Excellent work sir!
How does the car feel?
Power wise less or more torque in the bottom end? When loaded..
WOT?
Whine noticeable at highway speeds?
Hiccups, hesitation, anything negative?

Hello ATR!!
The CP3 pump is Capable of more Pressure and volume ouput than we require at this point.
It is more than twice the static displacement of the factory CP4.1 pump.
A CP3 pump is running England with some impressive Dyno runs and Countless hours under heavy load. I do not know details of the Turbo or Tune, But I do know that currently it is still producing more than enough Fuel pressure and volume.

Good work Andrew! Any chance of a turn-key solution coming from you any time soon?

P.S. With the new pump, can those with Stage II or III tunes and larger turbos take advantage of larger rails and injectors with increased flow rates? Right now, it seems the fuel system is the limiting factor for those trying to achieve higher HP/torque numbers.

Yes Amstel!! Certainly. After all these miles and torture testing on the English Dyno, the concept is ready for a select few testers.
The conversion is bolt on and anyone capable of replacing a Timing Belt can do it.

Excellent work sir!
How does the car feel? Not as Nice as my Wife!!!

WOT? No change. The pump itself does not affect any parameters you mention, unless other changes are made (Tune, ETC) and the pump is commanded to do more - or less!!
Whine noticeable at highway speeds? The whine is very faint. Only a gear head will notice. It is most noticeable at idle, free revving and you start playing with it!!! You will not hear it at highway speeds.
Hiccups, NO hesitation, NO anything negative? NO, but the techs at a dealer may scratch their heads???

Thanks Joe!!
All the best!!

Thanks Andrew! Just what we are looking for

Wow Andrew... I just got my kits from you installed, and who knows, maybe that cp4 will run for a few hundred thousand miles... maybe it won't... If/when it stops I know where to go! Cheers!!!

 

[Savageman69]

i cant wait for this, i got a tune and car that has rail drop that needs this. Plus im close enough to drive to you lol. Thanks for the hard work we all appreciate it big time

 

[YukonLT]

The experiment goes on!!

Great Progress Yukon!!!
So now that we have good data and many months and miles of testing on a stock "unmodified" car, (2micron's JSW) Yukon's awesome stage 3 Golf is going to help prove the Stage 3 tune.
Now.... Just need a regular stage 2 car for testing!!!
Wait, Wasn't there a stage 4 coming ))))?
Great work Yukon, thanks for the help.
All the best!

Fantastic guys...
Excellent work Andrew

 

[bobt2382]

^concur!!

 

[nate0031]

I'll do stage 2! Lol.

 

[mr_y82]

^tempting, right? haha

 

[2micron]

Just a question, but does installing this CP3 pump, have any bad or good effect on our damn emissions components, for those that still have them?

.
This was asked from another thread, let's generate the discussion about it here.
The kit was designed to be 100% compatible with the factory emissions equipment.
With almost a year of testing, the system has not had any noticeable difference to the DPF.
I have closely monitoring ash load and it is very consistent with the groups findings in the valuable DPF data collection thread.
Hope that helps your question?
Thanks,
Andrew

Click...Click...Click...Click...I keep trying to click the buy button but it doesn't seem to work

Any idea what time frames you're looking at for testing / Production?

The ECU is still in charge of injecting fuel and the fuel rail pressures developed are exactly what the ECU is requesting (perhaps better than stock?). Therefore, nothing important has changed related to emissions. If anything, I would suspect a slight improvement due to the relatively less intense pulsation in fuel rail pressure due to the single piston in the old CP4.1 pump. All the CP3 pump really does is change the hardware used to maintain fuel rail pressure, and it does this very well. There is absolutely no change to any parameters or components that have an effect on fuel delivery (to the cylinders), combustion, usage, or emissions.

Have Fun!

P.S. Andrew, I am probably about a year away from a timing belt job. I am going to want one of these kits when I replace the TB. They better be ready for sale by then.

The stock pump is actually a CP4.1, Don.

Oops, post edited - Thanks

[jackchit]

So maybe a group buy: cp3 fuel pump, fluidampr harmonic balancer and timing belt cover?

I'd be game for that

Market it as the tdi2micron "protection package"

This is fantastic info. Hopefully the DIY Kit comes to production soon! Have stage 2 now and this is one of the things needed for my future upgrades.

 

[umrpunter]

oh please yes make it so. I have a timing belt to do in a month or so anyways. Was going to pop on my 2micron fuel filter kit. How sweet would it be to put on this?! As always, great work!

 

[LovinPSDs]

Can I ask... The 2Micron filter was originally designed to protect against grenading CP4.1 correct? If you swap to a CP3 is it really required?

Also.. Just getting in on this thread as it'll be on my list when it's TB time. Interested to hear prices and timing for the upgrade!

The "extra" fuel filter shown is the 2micron "contain flow" filter bracket, but it is not being used as a contain flow filter. The fuel lines have been re-arranged and that same filter bracket now holds a 1 micron filter which is now on the supply side of the CP3. It is not being used to catch debris from a failed CP4.1. Rather it is being used as a super fine (1 micron) pre-filter so that the CP3 only gets super clean fuel. This is probably overkill for the pump itself, but it is good protection for injectors and other dirt sensitive parts in the system. Since they already have the filter bracket, why not use it?

Have Fun!

[turbobrick240]

^^I agree with what Don said, plus it adds some bling to the engine bay.

 

[LovinPSDs]

Guess I didn't follow this all the way through... Nothing wrong with perfect fuel headed into the pump! Nice work, looking forward to updates on the "kit"

too vague, he's done too much other good work, lol

Smile, I guess he could have "protection" stages like everyone else...
