Mounting Engine/ G rails
Now at the stage of doing the 'G' tubes for my Pinto engine.
Does it matter where they sit relative to 'C' tube and the 'E' tube?
By that I mean can I just place them where it's most suitable for the engine mounts or are there strength issues with where they connect to 'C' and
should they be connected to 'E' as they do in some of The Book pictures?
Hope that makes sense!
Cheers,
James

James,
Allowing for the fact I made my chassis 4" wider than book, I think I still followed the layout for these to tubes.
I'd be inclined to suggest you do the same, and make some different engine mountings to suit.
I originally intended to use 1.8 CVH, then decided to use RV8 - no probs with either.

If you knew how long I'd spent fecking around with those mounts you wouldn't say that! 
Mine is a wider chassis too- though I went about it a different way from you (just to make my life hard it seems in retrospect).
Anyway, I saw a mates Luego race chassis yesterday and 'G' doesn't seem to have to go where I though it did in relation to 'C' (ie. in line with
the two 'H' tubes).
Whether 'G' needs to connect to 'E' though (or atleast in the corner where 'E' joins 'F') is still bugging me!
Thinking about it though The Book does say move them where appropriate for the engine so perhaps it doesn't matter if they connect to 'E' or
not!
Aaagh!
Damn you Ron Champion!

For what it's worth, I put mine where they worked right fo the engine mounts.
All seems OK to me!

From a purely structural point of view, the G's should join the C's where H's rise from., making another very strong triangle. From a practical
point of view, this would probably foul the starter on the N/S and the clutch actuating lever on the O/S, though I cannot measure this as my engine is
still on the bench with the sump off having just been shortened.
If I have room when the engine is fitted, I will weld in 1" RHS between the base of the H's to somewhere along the G's dependant on any fouling
restraints. My chassis will probably weigh about 600Kgs on its own by the time I have finished, I keep saying another few grammes wont hurt, but I
have added bits all over the place to add strength or rigidity. Completed it will probably weight the same as a Sierra
