I had a look at RHOCARīs old site with buildtips how to lower the EFI chamber.
But what I canīt figure out is how he did it without welding. Anyone here got a clue?

This page

it looks like hes blocked the holes in the side of the plenum and re drilled/cut ones in the bottom to allow it to sit on a shortend inlet manifold. Maybe liberal use of selftapping screws and sealant!

hes wanting to sell the kits though so the instructions would be rather vague!

I have actually done this on my old car but in stead of using said self tappers i had an engineering company up the road weld the two bits together. I cost me Ģ40.00 but the resulting job was rock solid. I used self tapers and some ally plate to blank off the cut holes pretty much as in the picture at http://www.rhocar.org.uk/buildtipz/024.shtml
I do have a spare cut down unwelded chamber if you want it. Let me know and i will post some pictures.

Cheers

I would like to see some pics.

Send them to:

thx

Hi Jonte

i have put some pics on my web site at http://www.daxrush.org/Robin%20Hood.htm I didnt use vellum because i got the angle of the chamber slightly wrong. It would have meant moving the holes on the vellum for it to fit into my Robin Hood...Still all good experience.

I hope you find the pics informative

A different approach
