DI pump, update.....

[ptperformance]

OMG the stock material harness is through the roof.

Not going to tell you what it but its damn near the same as diamonds on the rockwell scale.

The Autotec units came back at 61 and 53, not very hard. There were damn near the same for the APR units.

Now you may ask why is this important? Because of debris issues and pump lock up. A metal that is to soft will let debris get stuck on it. A material that is to hard will break when it gets hit by debris. You have to treat lower grade materials in order to get them hard and the stock units are super uber hard. I will have 500x magnification pictures up here very soon to show you guys what the differences are.

We had to cut them apart to verify harness and what type of process that they used for the stockers so ours can be just as hard. Reason for this... how many stock pump failures have you heard of? Not one that I can think of. So, cut, polish, mag, and pictures with a camera at resolutions way beyond anything you or I can buy and what do you get? A $750 test that confirms what I have been saying this whole time to the machine shop... make them out of a harder material and these failures will not keep happening, now they listen.

Have them eat that $750....

Sorry, I wish it worked that way. I have heard of a few new failures coming from the Autotec pumps this last week, I hope none are from our local guy here on the forums. Seems like the last batch to get released was a little soft.

Well if I was going to use another companies pump then I would not have to do all this work, but since I am.... might as well do it right the first time around.

It'll be the only one available specifically designed for the MZR DISI application, so you'll likely get alot of business for it.

Thats the idea. It should work in the VW pumps as well but I am still waiting for someone to send me one of there pumps for upgrading. I have an Audi pump sitting here and they look damn near the same internally, no testing has been done with that pump just yet.

Thank you, I would like to say I told everyone so but that would be wrong.

Any update on availability of the check valve upgrade / pricing?

[ATE BALLER]

It's only a spill valve correction and a PCM update. The "free" CDFP mod should far excede anything Mazda will do for us. From what I understand, their actually slowing down the spill valve's reaction time to give the weak ass pump enough time to keep up with the injectors. The PCM reflash likely does what what it can to keep this from increasing fuel-lag, maybe by advancing a bit of timing. IMO, it's not worth my time when I can get a way better pump anyway.

WOWOWOW, what the hell, are they admitting this is a problem? Is this a free fix or are they making us pay for it. I knew it, I said this a long time ago.

Monday I will have something for you guys. I want to test it on a smoking locals smoking care first. I will have pictures and a how to ready for it. The thing is going to be a pain in the ass to install.

Yes the CDFP mod will move more volume but the ECU flash is what has me interested. If the crank up the injection PWM a bit that will give us a ton more fuel with the new pumps.

I highly doubt that they would take more fuel away. Higher flowing spill valve would make more sence the slowing it down. Either way I suspect that we will start hearing about the pros and cons of these soon enough.

They are saying, sorry and it should be a free fix for sure.

Its monday.

How is this different than the pump mrlilguy is offering?

Aside from the obvious fact that his is available and your isn't <-don't take that wrong - just curious about the options available and soon-to-be available.

Its all about material used to build the pump upgrades. I could just use the Autotec pumps like mrlilguy and sell them for less to make the market more competitive, but why?

Our pumps will be engineered to application specific. They will have the proper materials, treated, bigger spring (if needed), ti' spring retainer, chome locks and coated like the stockers are. These will more or less be built as if Mazda themselfs wanted this upgrade done to the high pressure pump.

Last, price. We hope to have them on the market for under $300 and that will be with a lifetime warranty on the parts. Seems like saving a few hundred dollars for a better part might be worth it if you ask me.

Time will tell...... till then keep up the late nights

Will do and thank you. The new batch of tool steel has been ordered and the retainers and locks are on the way. Last thing is getting the material treatment done and coated. We think that the material treatment can be done at the same time as the coatings, we shall see. This would drop the price another $20 to $30 per unit. That would be great.

I will keep you guys updated as we continue to get these built and tested. So far it looks like we may have the proper clearance, treatment, and weight ready for these. Now its just time to start the testing of these units, more on that later.

Currently, I'm mostly interested in the free mod. I've got a rail on it's way the house, and I just want to know how much I can get away with opening up the orafices for the injectors and the rail inlet. Does it need to be machined smooth, or can I do it with a drill press? Should I make it a straight-through hole, or tapered one way or the other? Will it be alright with a stock cdfp backed by a Walbro, or should I wait until I upgrade the cdfp? Should I open it up just a little for now, and more when I upgrade the cdfp?

[Laloosh]

lol i think you should start saving for a rebuild....in all due respect what you are trying to do is pretty daring and will probably bite you in the ass

That's why I'm asking for his advice. He obviously either has the answers, or knows exactly how to figure them out. All the things I mentioned are what he is testing anyway. I don't think increasing the size of the injector opennings is going to have any ill effect on the injectors output, but I'm thinking the restriction in the inlet might act as a wall to prevent back-pressure and keep the rail pressure a little steady so the rpr can do it's job, so that one might be touchy.

[Laloosh]

well good luck if your going to try to figure out!

25% increase in size seems to be about the right amount. It needs to be smooth and very clean, any sharp edges will cause problems.

Next you will need a CDFP in order to get the most of of this. There are other areas that need to be cleaned up and taken care of as well. I will have more details on this as we move forward with the updates on the stock pump testing.

It has zero ill effect on the injectors, it helps if you are running higher boost levels. The feed line into the rail needs to be opened up as well. The pump dump valve needs to be changed or machined. I am doing one of them this week and the other when we get the parts instock. There are way more differnet ideas to change this or that with the fuel system and I hope that Cobb AP has them built into there tuneing.
