High Pressure Fuel Pump

[WhiskeyTango]

Just received my Hondata FSU on Monday. Trying to decide if I should try and return it, or take advantage of the system with its extra componenets, i.e. the injectors, fuel lines, in-tank pump...

The one thing I find odd is I can't find any info on Hondata's included injectors. Anyone know the flow rates?

I've had the goal of no more then 450whp with a drop in turbo, full bolts on's (94 octane) with now potentially this XDI fuel pump..from what ive researched I'm assuming this pump will be sufficient to handle that power level?

apparently without the injectors the pump can handle a 480whp+

they dont mentioned the flow rates but just says it flows 20% over stock.
The XDI 1400cc injectors say they are 25% over stock. So if that is true, the stock injecotrs should be 1100cc with the hondata injectors being somewhere around 1350cc

I'm now an authorized dealer of XDI products! There's currently a 1-2 week lead time on new XDI EVO units.

You can get 25% off any tuning service when purchasing the pump as well by using code 'EVO'.

You are THE MAN!
Do I have to buy the tune at the same time to get the discount bundle? (sorry if that is a silly question)

Just message me later and I'll set you up with a 25% discount for the tune. Normally, though, yes.

For those of you curious about modding the fuel line, this thread has the most info. Although it seems like a delicate process.

As of this morning they had 5 XDI in stock .
Per Full Race . After that 2-3 weeks for them to ship it out .

Yeah they’re sold out everywhere. Current lead time for dealers is 1 to 2 weeks.

I ordered mine yesterday evening. Hope I get mine soon ?

Do you have to have Motec to use this new HPFP. "At this time, you are NOT able to run this fuel pump with ANY OEM ECU tuning software solution. They lack the capability to alter a few critical components, that are easily controlled with Motec or other motorsports grade ECU. " Full Race Website

This was updated on Full-Race's website this morning. I spoke with them earlier ordered the pump. At that time they still had a few in stock. XDI is to supply a code to unlock this in the Flashpro manager software. It is free. I don't understand why this is necessary for Hondata to do. The FR turbo kit did not require a code to unlock in Flashpro. According to Full-Race the XDI injectors are not included with Hondata's built in calibrations. They didn't say if they would be in the future so I can't comment on that, but here's the dyno graph they sent me.

FOR PEOPLE TALKING ABOUT DRILLING OUT THE FUEL LINE:
It's your car to modify how you want, but realize it's a HIGH PRESSURE fuel line and that is a VERY BAD IDEA. A common problem on other direct injection turbocharged platforms that have been around for a few years longer than the FK8, is these lines cracking after a few years of operation. Usually you can't even see the crack, you'll just have 1700 PSI fuel spraying all over your hot engine. and me personally, I try to avoid lighting my cars on fire, but you do you.

@Jpierro79 Before you go on another rant about the brand of dyno Hondata chooses to use, please understand that using two separate dynos of similar or different brands to compare anything is not the intended use of a dyno, and frankly is wrong. Some dynos of (insert your fave brand) read low on some days and on others will read high.

The reason dynos read differently is due to how the calibrator sets up the dyno. You can set up and dyno to read high and you can set up any dyno to read low. Every calibrators goal should always be to have an accurate baseline, but the fact is you will never reliably use some guys dyno numbers in orange country at sea level as an accurate comparison to another car in Colorado. Correction factor is a complicated subject, and you are not helping anyone understand it with your rants.

Some dynos are loaded and some are not. Some dynos simulate driving conditions and some do not, but it is always a mathematical calculation that is set up by the dyno operator. Depending on what inputs and correction factor you enter in the programming, you will see dramatically different results. Further, if you don't know what you're doing regarding weatherstation data, relative humidity and air temp, the results are off. There are many different methods for doing this and it's not a standardized thing amongst tuners. If you want to be ultra nit picky about the brand of dyno a company uses, you need to understand that dyno graphs are NEVER a means to compare two different cars, especially not two different cars at different altitudes, under different atmospheric conditions, with different fuels, even the manner in which you strap your car down on a dyno and the tire pressure / amount of tire tread and wheel's weight will make a huge difference in the results you see on the graph. Good calibrators adjust for correction factor and use these tools to do one thing, optimize a single vehicles performance and show gains in power and efficiency on one a single day under the current conditions. If you want to measure your car against someone else, drag racing is a good way to do so, but the same principles apply, you know damn well you're not going to run the same 1/4 in Denver as you will in Pomona, so obv we don't want to hear about them being compared. It confuses the heck out of people who already don't understand a complicated and subject.

as far as i know, those numbers are both a guess. No one *actually* knows the stock flow rates. We suspect ~800cc, just becuase the stock injectors will run out around 450whp if you have enough pump to feed it.



All this is up for debate though

I’m sure someone has bench tested them and knows...

yeah couldnt really find any info at all. its all just assumption on my end.

 

[BrokeCTROwner]

I’ve heard that the oem injectors were 850cc
