Dynosty 1000 Fuel System

[Dustin@Dynosty]

We have seen DynoJet comparisons of our tuned cars ranging from 10-20% over our Dyno numbers, just FYI.

The rest of the components are designed to be as free flowing as possible. The -6AN feed line could be a restriction for someone shooting for 1000hp but this setup can always be upgraded to -8AN and it would be no question.

i like the sound of that

wow looks awesome!

Looks promising!! would the factory fuel rails be a limitation too? or is it just the fuel pump and the feed line?

Aftermarket fuel rails are needed in order to convert the stock fuel system from returnless to a system with return

Given the tight constraints of the FR-S/BRZ fuel tank and hanger, we looked at all options including surge tanks, new pump hanger, etc. We ruled out surge tank due to lack of space for a proper vertical surge tank and not wanting to put a tank of fuel in the cabin or trunk compartment. A new hanger was drawn up, but ultimately we found a way to get a Walbro 485 in the stock hanger which provides the greatest value to everyone.

The Dynosty 1000 Fuel System is a full feed and return system that retains the OEM venturi system (draws fuel from the other side of the saddle tank), allows for more fuel flow, and keeps everything concealed safely under the factory panels as designed by Toyota/Subaru.

Pictured above are the billet aluminum components included with our system along with -6AN Aeroquip Starlite feed and return hose, your choice of Aeromotive or Fuel Lab regulator and inline filter and appropriate AN fittings.

Pricing, more details and pictures to come here very soon!!!!

Included will also be our billet fuel rails that retain factory dampers which are currently available here,

Three things.

1) finally someone made this

2) Im very excited

3) why in the eff didnt you call a brotha~!

Not to sound like an ass.. but are you really fuel limited with the vortech?? or do you have an upgraded blower no one knows about?

[Dustin@Dynosty]

Thanks for all the kind words.

As soon as we have confirmed pricing (should be with in the next 2-3 weeks) I will post those details up. We have 20+ machined kits in stock, so just down to some final testing. We would like some more real world testing on the venturi side just to make sure what we are simulating in the shop is going to happen on the car through multiple cycles of gas.

With that said, if anyone puts a considerable amount of miles on their car per week and is interested in this kit and willing to do some testing for us, shoot me a pm. You would need to be able to do the installation yourself, need to be able to burn through a tank of gas per week, and we will work out the compensation side. Doesn't matter if you are making 150 or 550hp for this testing (obviously unless your FI you probably do not need to upgrade) but the only testing we will be looking for is someone to monitor the fuel level in each side of the tank when the refuel light pops on to make sure the venturi is working.

And more things for me to buy.....ughhhh time to work more i guess.

I could do that in the spring but the damn snow and cold means my car is hibernating

I edited my last post as well but just a little additional on the testing:

Doesn't matter if your on E85 or gasoline as long as you are using at least a tank per week.

Would FI guys benefit from this? Im still NA, but would like to know if this mod would be something to consider when i go FI. And about the testing, how would one monitor fuel levels on both sides? i burn about 2 tanks a week.

Is the venturi the only thing that moves fuel from the far side of the tank to the fuel pump? If the venturi wasn't working right, say it was moving too much fuel, that would drain one side faster then the other, would it not? And after one side was drained, could the venturi cause the fuel to become aerated? And...(I know this is probably getting annoying, but there is a point to this) if the fuel were getting aerated could that cause a knock condition? Is there any way for the fuel levels to equalize?

I'm asking because I noticed that as my car goes below half tank the advanced multiplier would start to drop like a rock. I thought it was due to the age of the gas and not the fuel level, but after talking to a friend of mine who's a chemical engineer and used to work for a petroleum company, she told me that was unlikely. She said it wasn't impossible, but it didn't seem to fit.

Thanks and sorry for thread jacking.

It would probably entail opening the hatch under the rear passenger seat to visually check the fuel level. It's no fun and, if it's like the driver's side, you'll be swapping a gasket every time.

Edit: there's actually a fuel sender gauge on the passenger side, as well. Now, whether ECUtek or similar logging app can pull that sensor's value is another thing all together.
