XDI or Full Race HPFP

[Two Step Performance]

If only people with personal experience speak to a given matter.

My v2 line broke at VIR. I saw another V3 fail at the same track event. My statement isn’t what I heard or read on the internet.

If you experienced a failure and worked with Full Race to get things checked out, thank you for that. As a Full Race dealer it is of high importance that any potential issues are investigated and resolved because we do not wish for any of our customers (or anyone in the community) to experience such trouble.

My understanding is that in most all cases of failures there was evidence of installation error and the V2 and V3 iterations were to combat the ability to run into that. I certainly do not mean to imply that was the case for yours, just sharing the information I have. Full Race has been unable to properly investigate the reported failure of the V3 line because the other party is unfortunately not cooperative at this time.

the XDi soft line isn't a viable solution? Or just unproven?

This is the line 4 piston uses. I called them about this line. They are no longer selling it because they never intended for them to be sold to the public. They claimed to me that they were only for certain racing teams, and only put them on the website for ease of the teams to buy new if needed. Apparently there is debate whether or not they work with the full race pumps fittings, and if they are or are not E85 compliant.

If somebody could actually buy this and advise if it does or does not work with the full race pump and if not how to resolve it in a tutorial style fashion, I would be all over it.

So can you not buy the XDI fuel line anymore?

Was wondering what its max whp is. Guessing since it says 24% more fuel would mean around 100whp since oem fuel maxes out around 400whp… so this system might be 480-500whp maxed out? Was wondering if anyone ran it and wanted to chime in

I’m curious about this too. It seems like the most cost effective option for those not looking to make hp in the mid to high 400s.

IIRC the standard Hondata fuel system is good up ~500whp(don't quote me on that). One of the concerns with the Hondata fuel system was the hard line that has a restriction that some tuners would drill out to increase flow since it had the bottleneck like the stock hardline.

Best to check the CivicX forum and see what numbers the FK8s have been running with that system.

I have been unable to locate one, if anyone knows let us know please.

Let’s understand a few things here. The track community is small. There’s a handful of FL5 owners with the XDI or Fullrace fuel pump that tracks the car.

The Fullrace pump costs around $1,500. Yet when it breaks, customers are set to Nostrum for support. Why is the Fullrace name on the pump? They are at version 3. At which version should existing customers be with a working line that will not break at the track?

It is always easy for manufacturers/vendors to cite or question installation when there’s a failure. My line was installed by a mechanic. It is his full time job. Do we need to assess one’s capability also to have it installed “professionally”?

For the folks who have had no issues with the pump. That’s great. This pump has failed with people on the track. Manufacturers test for durability sometimes at 24hr races. Going on a spirited drive at a touge or to Wholefoods is not the same as the track. This v2 line failed after three 25mins sessions on day 1 of a 3 days HPDE.

I’ve shared which RMM I have and Hondata datalogs with Nostrum. I didn’t send in my broken line because I decided to send it to someone who’s going to build me a new line. I’m not optimistic on v4 to be the final solution based on track record. If v2 and v3 were created to remove the possibility of install error, then why is install being questioned?

As of now I have a $1,500 part sitting in a box. I have invested time and money into this mod. So if this reads like it’s written by an unhappy customer. It is. I’d be happy if Fullrace offered to buy back this pump and reimburse me.

The 4piston flexible line does not work with the Fullrace pump. It does not thread. I bought it and returned it because that was my initial solution to not have the possibility of v2 fail on me.

Hate to be that guy but, Uhhmm actually!!!... the pump is $1999 before tax, soo that's quite an expensive paperweight you got there.

Come on, this company is on version 3 of something that can and has potentially to set a car on fire, there is no defending this company even if someone is not sharing the culprit line with them, if we think about this, there is probably a reason its not being shared and not because they don't want full race to figure out where they went wrong now 3 times.

Again this is not 1 person here or there, I personally have witnessed it as well not once, but 3 times now with different versions. Not to mention that there has been more than a few people with the issue online that have posted and also posted videos.

Lets not pretend this was proper behavior from this company, this product does not seem like it was tested properly.. I could have even said ok, crap happens, v1 to v2 but now at v3 and still having issues? for a $1500 part? this is bonkers to me.

I should have sold you mine. It was in my car just in case. They let me return it though. The fitting wasn't an exact match and the hose wasn't fully ethanol rated.

I vouch for this person as I was there with him when it happened.

Stock life no fuel lines issues ...

Its okay brother. That is what I have heard from multiple sources on both accounts regarding the thread pitch and ethanol rating.

 

[SKINNIE]

from what I've read, it looks like the issue is with people installing the fitting into the pump housing incorrectly, and when tightened down it causes the failure. I'm 6 months into my full race HPFP and have 0 issues.

Can be user error or combination of both bad design hence why they're on Revision 3 of the fuel line. Also, people have had their REV.3 lines fail on them also.

The car that caught fire at VIR was V3
