....don't know how much it will help you all...
but I've been compiling quite a site around DCOE's.
I have tuning info, charts and tables, and a photo page
of users installations with the engine mods and jetting
being used listed with their photos.
http://www.teglerizer.com/dcoe/dcoedata.htm
It started out as a Spitfire page, ...actually I was testing
and writing up a comparison of running a single DCOE 45 vs.
dual 40's on a Spit. The site now includes Spits, MGB's, Spridgets,
and even a TVR and a Ferrari.
Anyone else care to add their specs and a photo...send them along!
