Info and facts about the Wilson Manifolds D Rail for the Evolution
 

After looking at what has been offered in the community, we decided to apply the ultimate solution in fuel rail design used in many forms of professional racing to the Evolution. This component was a design exercise to prove it is possible to include features that are common to the racing industry in an aftermarket application.

This is the largest internal volume rail on the market, larger than -10 AN rails by 11%.

It has radius injector feed inlets to aid fuel flow to the top of the injector.

The proprietary D shape of the bore of the rail decreases pulse waves and turbulence to the injectors.

The rail fittings offer 100% use of the stock regulator, return line, and feed line.

It can also be fitted with AN fittings.

There are two 1/8 NPT provisions with clearance for 90 degree fittings for a fuel pressure gauge and nitrous.

The rail has a radius instead of a chamfer to reduce the chance of cutting an o-ring on installation.

The proper amount of injector seal crush has been engineered into the mounting system to provide a boost leak free seal.
This thread was formed to educate the community on the advantages of a properly engineered component.

Very Nice looking Jim! I like the 1/8NPT ports on the bottom of the rail! Much cleaner install if you are going to use a 'compact' Fuel Pressure Sending unit like the older AEM ones. It would also make a much more "hidden" Nitrous install if your nozzles are underneath.

Keep up the good work!{thumbup}

Proper engineering oozing with awesomeness. I'll take one please.

Looks very nicely done.

Any chance they can be gotten anodized internally for E85 use? :)

Very nice product as always. Cost estimate?

Looks like some quality craftsmanship!

Very nice looking piece. It's Great to see a company put some thought into a product that is so important.

This isn't the fuel rail stock that can be bought by the foot and simply cut down to the length needed. {thumbup}for the real deal.

Jim, the injectors will be sent to you tomorrow. In the mean time, DO NOT SELL MY RAIL!".

Is this it?: http://9sec9.com/shop/article_FU-1/W...6aid%3DFU-1%26

The prototypes are internally anodized with just the injector bores machined. We have been running a rail for months in Florida. The rail in the photo was a final prototype for me to sign off on for production and show the features of a properly designed rail. Thanks, Indy

Jim that looks awesome.

Nicely done!!

Thanks for posting up Jim great looking piece!

I will post that over on our local forums for ya.

p.s. So sorry i haven't had a chance to give you a call i've been super busy getting my car back together trying to get some easy miles before i head back out to the drag strip hopefully this Sat.

Very nice and competitively priced as well.

Can't wait to get this Jim!

Thanks for hooking me up {thumbup}

Good luck at the track tonight!
