Fuel starvation, who else?

travisjb

My setup gets me down 9 gallons from full but sure would be nice to be able to drive it all the way down to empty or close to it... count me in if it can do that, and if he stays on track with his price target.

I'm in... IF it works.

I broke a fuel baffle plate, not sure if that has anything to the cheap quality of the OEM tank/pump assembley

Right now, I can only get through about a 15 minute session with the tank completely topped up. If the tank is down about half way it will even display the symptoms on mild right hand turns on the street so it's not just for use on the track for me.

I started working on installation/fitment/supporting components today. Basically starting to figure out the hoses, lengths, attachment points, etc, for all of this. I took some really cool videos from inside the gas tank as well. Really puts everything in perspective to get a view from inside the problem environment.

I dont envy the guys that work at shops that will have to install a bunch of these! Working thru these 4" diameter openings in the gas tank really sucks! We will be making some pretty clear instructions for those who want to do it at home also. It actually isnt anything that will require crazy tools or experience. Just a careful hand and patience with the frustrations of working inside a gas tank.

well I'm ready when you are. I have the interior out and ready to give it a shot. Will I need to drain the gas tank too?

it doesnt matter if the tank is empty or not... but the less gas in the tank, the less gas you will get all over yourself and your car. it would be recommended to have next to nothing in the tank.

Are you going to be willing to do installs, phunk? Being so close by I may try to avoid playing with the fuel system myself.

phunk

Yes we will definitely setup a fair installation service for it. While we are not a tuning shop anymore, just a manufacturer... we do have a bay with a lift/etc for R&D. Not that a lift is needed for this install anyway, its all done from the interior access panels for the tank.

In case I missed it elsewhere is your upgrade going to include a better fuel pump itself?

Yes it does include its own fuel pump which will become the primary pump for the engine. The stock fuel pump will become simply a transfer pump, or an "active pickup" if you will. We are rating its HP potential to 550rwhp using gasoline. Later, when needed, we can offer an upgrade for it for those on a built motor with FI who want to make more power.

Our product is, in essence, a surge can. We sort of took that theory, expanded on it, and tailered it around the 370z. It is built specifically for the 370z gas tank, and mounts to it / inside it. It does not require a return fuel conversion and external regulator in order to keep the fuel siphons operating correctly like an external surge can would for these cars. And it does not maintain any pressure inside the can as a result of feeding the restrictive venturi siphons through overflow fuel, which is how we can feel comfortable putting it inside the gas tank. Because it is inside the gas tank, it includes one of its own very potent fill siphons on the drivers side of the tank, along with the stock fuel pump assembly on the passenger side being the major source of fill.

It does not require any plumbing changes outside of the fuel tank at all. Everything is happening inside the fuel tank. The only thing going on outside the tank is a relay and a few wires that route into the gas tank through an OEM quality electrical bulkhead to the new fuel pump.

So its like a surge tank on steroids. It has several additional features over your typical external surge can.

Our theory behind it involves 5 lines running back and fourth in the tank. 1 being the stock cross-tank siphon. which remains untouched. 4 that we add, all of which interface our product with the oem fuel pump assembly.

Thats about it for the info for now. We are actually working on it for other applications as well. We believe it will be a big hit, and we want to offer it for a few platforms very shortly after the 370z.

Like what I'm hearing!

Phunk, will this eliminate the issue I had over the weekend where the top plate and the rods separated due to the weak structural linkage? Ie are you reinforcing or replacing that structure in this new product?

Also, would like to recommend that you start a new thread with a press release when you are ready so the conversation can stay focused on your product... will help when new people stumble across this issue down the road as well

Side note... NASA and some other sanctioning bodies assign "points" when you use a non-OEM fuel pump... will be well worth it to carry less fuel / weight, but just fyi

I tend to believe that what happened to you over the weekend may be an isolated occurance. Our product is mounting on the opposite side of the fuel tank, and merely interfacing via plumbing with the OEM assembly that broke on you. It would not be too difficult for us to contruct some structural reinforcement for the OEM fuel pump assembly if there is a problem with its integrity. It would be entirely independant of our starvation resolution product.

I will definitely start a new thread for the finished product. We want to market it with a little motivation, I think it will be a popular product.

It is strange that they assign points based on a fuel pump upgrade alone, as a fuel pump doesnt increase horsepower or anything. But it is for certain to enhance track times if you dont have to drive around a problem or deal with momentary power loss.
