Livernois Firestorm HPFP Installed

[StealBlueSHO]

So I have been waiting to get my hands on one of these for QUITE some time. On my 2010 I ended up going with the Alky Kit to resolve fuel pressure issues since the HPFP upgrades were not available. However, on my virgin 2016 I decided to pull the trigger. 

A BIG shout out to Cody over at LMS for answering my questions, putting up with my canceling, then calling back to place the order, and the 5 different tune revisions I asked for. Then for answering a couple quick questions for the installation.

Installation was super easy, if you follow my how to on the HPFP replacement, its pretty much spot on... a couple changes...

1: You will need to bend the high pressure fuel line SLIGHTLY up so it will line up with the new pump
2: The electrical plug needs to be unbound from the taped up wiring harness. This will include cutting back the tape to free up the plug so it can reach the new pump.

Those are the ONLY two differences between putting in a stock pump and the Firestorm pump. Silly easy..

Initial datalogging shows MUCH more stable fuel pressure, fuel pressure is holding desired where as before it was dropping well below 1000psi which is downright dangerous if sustain, which is was.  The car drives really realy well.. smooth, pulls through the RPM range smooth.. very happy with this purchase and support from LMS.

Congrats there Bud! I'm a tad Jelly starring @ that beauty..  :thumb:  I hope it proves to be worthy and then some...
I'm anxious to see some actual time-slips @ the track.  Best of luck.  Z

Nice, I like it.  Is this just the Xtreme-DI HPFP rebranded as Livernois?  The XDI installation video makes the same note about bending the HP fuel line.  XDI apparently includes a wiring extension to reach the pump electrical socket.

Thanks!!! No, they are different pumps.

Why is 1000 psi dangerous if it holds AFR?

Why is 1000 psi dangerous if it holds AFR?

There was an article about DI motors and blow back into the injectors when cylinder pressure exceeds what the injectors pressures are. But besides that, I have run extremely low pressures before ~700psi and the motor runs like crap, the ecu starts to close up the throttle, and it doesn't perform well...

Then there is also the whole discussion about properly atomizing the fuel in order to help cool the cylinders to prevent knock...

I can dig up all the articles, but its not just about AFR's.

Most tuners don't like seeing anything below 1500psi for safety reasons in any event...


I am sure you have seen and experienced the issues with low fuel pressure while you were nailing down that E85 tune with Brad.

I do wonder if 1450 is the safe threshold as far as backpressure is concerned....that is the psi the max flow is rated for both Injector and pump.

Z, I wouldn't be jelly if the appearance cover doesn't fit anymore.  LOL.

Mike, the new pump looks great, and glad it is functioning as intended.  Now you can breathe easy!

 

[StealBlueSHO]

FYI... the cover DOES fit back on....

That IS a change then.  Doubly awesome upgrade!

 

[FoMoCoSHO]

That's good because it's against Federal law to remove it....i wish I was kidding but I just read that in the cmax OM....wtf?

 

[SHOdded]

  It's against federal law to breathe LOL.  But then you have a hybrid.

What is the difference between the Xtreme and Livernois pumps?

What is the difference between the Xtreme and Livernois pumps?

Two different developers... in all honesty.. I am not sure there is much difference? The entry level pump from XDI claims 35% more flow while the LMS Firestorm pump claims 40%...

The LMS pump is $200 cheaper as well.

So what is the limit of this pump then HP wise? Approximately. I get that this saves your motor for sure and is worth the money.

 

[StealBlueSHO]

Tricky question... LMS won’t tune past the limits the drive train which they feel is about 450awhp/450awtq on a stock block. So there are guys with a similar setup that I have that are dyno tuned to those numbers.

Of course it all depends on how good the fuel is in your area as well. Generally these cars are fuel pressure limited and not knock limited if you live where the fuel is good like myself.

With this pump it’s becomes reversed right? It’s now knock limited as opposed to fuel limited...

So that leaves Ethanol mixes or meth injection to raise the octane levels...

Matt Robinson at GearHead has an xdi-35 pump and is running E30 to produce 500/500 if I recall... but E mixing adds more complexity...

It’s not a straight forward question I suppose...

Rodger that.

I am tuning with Brad shortly so That is why I am curious.

I live where the fuel is good. 93 Sunoco. E85 is abundant and it is regularly tested by the "Race" guys.

Cleaned up the install a little bit. I trimmed back more of the tape on the harness to give me some more slack on the HPFP electrical plug. This allowed me to add a proper sheath on the wiring AND move it off the HPFP. I noticed that the pump gets super hot and was starting to melt the tape I had wrapped around the exposed wires.

Looks good. Spendy but will add a safety margin as well as allow more aggressive mods down the road if you so choose.

Yes, it was a good chunk of change, but fuel pressure will not be a concern in the future. Being as I really want something is set and forget, this fits the bill. I really like methanol injection.. but there is always that bug in the back of your mind that if the pump fails.. or you run out of meth when your not close to some where that has it.. etc etc etc...

This will also support bigger turbos as well
