The BTP Fuel Delivery Kit is now ever better than ever! It provides precise fueling to each injector and also allows for 35% more flow! This will meet the needs of the most demanding system using pump gas and also allow for the use of E85!

The E85 Fuel Delivery kit comes in the same layout as the standard kit, but with larger AN lines, larger fuel reservoirs on each injector, and a larger distribution unit. For consistent and reliable fuel delivery the E85 Fuel Delivery kit is the best choice!

The BTP Fuel Delivery Kit is better than any fuel rail available! The E85 Fuel Delivery Kit comes with PTFE lined stainless hose and anodized fittings to work with any ethanol content. The Fuel Delivery System includes the mounting rail, fuel line, fuel distribution block, fittings, and mounting hardware. For use with the 1990-2005 & MSM Miatas for E85 applications ONLY! The E85 system will not include a port for the OEM fuel pressure regulator.

 

What in the hell...

 

Saw this picture on the product page, i'm guessing the pictures on the product page aren't of the E85 kit?

Also: Is this a customer or shop car?

 

Is the fuel leak a feature to keep the fittings lubricated?

 

So it's a kit to relocate the fuel rail to the firewall?

 

The photo is the old system sent by a customer. The new kit looks virtually the same. Other than the diameter of the stainless lines, the parts are externally identical. We've had several customers request that the Fuel Delivery kit work with E85 applications. So we were able to make the internal flow area larger and use larger fittings to meet those needs! The main block can be installed just about anywhere, but it does mount better to the firewall. It will work with aftermarket intake manifolds as well as OEM intake manifolds.

I think my main confusion was that the ad copy states that it does not have provisions for an oem FPR, but every picture you have of it shows an oem FPR.

 

Whoever owns that car, they should replace the Gates LOLA feed line that is not rated for fuel.

 

And the worm clamp on a fuel line.

And whatever that weird thing on the firewall that's blatantly leaking is. Seems like whatever it is, it adds a huge amount of failure points.

 

This seems a bit of a bald claim and I find it very hard to judge that myself from a 260x260 pixel picture.
Please explain me why a fuel rail with more potential leaking points than a colander is any better than, for instance, the Radium fuel rail or Flyin Miata fuel rail? Both those rails should be big enough to support north of 500 horsepower on E85, so flow potential is not really the main factor when it comes to defining which one is best in my book.

 

I mean I can only count 20 potential leak points in the fuel rail setup above. Compared to the radium that has what 5.

 

Version 2.0 will mount the fuel rail on the gas tank and just run four lines up to the front of the car. You heard it here first

 

I think running 4 oem fuel pumps in the tank each feeding an assigned injector would yield more even fueling per port. Plus then you get huge delivery with OEM reliability. Miata.net approves.

 

Version 3.0 will just have 4 fuel pumps. 2000 HP CAPABLE!

 

I didn't even notice the fuel line in the picture that clearly reads "NOT FOR FUEL INJECTION SYSTEM".

 

And even if it was rated for fuel the potential for it being sawed in two by adjacent steel braided hoses is enormous. Steel braided hoses chew through everything they contact when vibration is present.

 

This kit was originally developed because the stock rail would not fit with a (gasp!) Supercharger. Testing then proved that there was virtually zero variance in flow between one injector to the next. You can't ask for much better precision than that. Further explanation here. Adequate is not the same as accurate. Many people have used the original kit to fit around other parts, provide accurate fuel, or they like they way it looks. As for the potential leaks, only the installer can determine that with the attention paid to detail when installing it.

Correct,if the intention is to use E85 the kit will not have a port for the OEM regulator as an aftermarket regulator is needed. We can accommodate the car that also need the OEM regulator in place. Those situations should be very few, but we have the parts available if needed.

What is the variance in flow of a stock setup?

 

Good question. I can't see product development continuing if initial testing was not better than stock. Otherwise, the part would have died with the supercharger kit. I was not directly involved on initial testing years ago, and I do not see the answer in my notes. I will talk to the person who was involved with testing to see if I can find out. Give me a couple of days to get back to you on this.

Typically brutal MT.net thread. Maybe this product is actually really good, although I've never felt like I needed it. But launching a product on the forum with a photo of an old prototype that was incorrectly installed, uses the stock FPR that isn't supposed to be compatible, uses fuel line that is clearly marked as not being for fuel, and is actually LEAKING FUEL, probably wasn't putting your best foot forward. I'm going to show this to my marketing guys as an example of how not to launch a product.
