Fabricated Fuel Injector
RacinJacin:
Hi Guys (and Gals), My friend Greg K. (the Frenchtown Flyer) thought you might like to see my Homemade Fuel Injector I am working on for my FED. I am not a machinist by any means, but I do know a few and they are gracious enough to give me pointers from time to time. I fabbed everything in this video, except the barrel valve and spool, which I am working on now. I hope you enjoy it.

THE FRENCHTOWN FLYER:
Thanks for posting Jacin. For those who don't know him Jacin is an excellect fabricator, as evidenced by his completely home built FED, from the engine to the chassis to the tinwork. Here's an older video of him racing my old Logghe (orange) altered. In this video he's got an 8.0:1 blower motor long block but without the blower, which is what his new injector will supply fuel to.

WHAT FUN!!!

Jacin – enjoyed seeing your video. Yes will certainly improve the looks of a 409, or hemi. I’ve sanded, buffed and polished a few items, worth all the effort as verified by your video. You must have alot of unrestricted time, 99.9 percent of the rest of us would just buy a metering valve : ) Quick question, what’s the butterfly diameter? Alan

Hi Alan, Actually I have less time buffing and polishing than you might think especially with the base since it was machined pretty smooth to begin with. I also learned a little speed when doing the top - which amounts to - USE those different grits!!!! :-) Advice I wish I had learned long ago. Presently I DO have a little extra time now as my previous employer decided they could do it better in China and Isreal. Rotsa Ruck with that! :-) As for the butterflies - they are 3" - 10 deg. IIRC it works out to ~28sq. in. and the scoop is slightly larger. I did the barrel valve because I think I may have seen a place for some slight "improvement".

28 sq. in., excellent, do you know what the original Scott Slot was, I think it was closer to 30 sq. in. For that mirror finish, the more you do and learn the tricks, the easier and faster it goes...
