Placing carburetors directly above and exhaust manifold is a simple
measure of IQ. He who does so seriously flunks the IQ test.
Almost every Jensen Healey in the yards burned due to this
brilliant engeneering scheme (plastic ‘‘T’’ piece between the carbs
cracks due to the heat of the exhaust manifold directly below it
and then drops copious amounts of gas onto the offending maniforld!)
I have a very good friend whose V-12 roadster and his garage burned
to the ground because of exactly what you say – the plastic push
on gizmos and O-rings in the bottom of the carbs rotted. He was
fortunate enough to catch the fore before the entire house burned
down.
Just know this and replace them periodically and check for leaks.

I second Jeff’s advice, I replaced mine 3-4 years ago and no subsequent
problems. However I share your concerns about fire, I carry two fire
extinguishers-one halon and the other a regular type just in case. I
hope it is like most things in life-if your ready for it,it won’t
happen.On Monday, December 6, 2004, at 02:40 PM, Jeff MacGregor wrote:

Tom:
All the usuals have these plugs; you shouldn’t have any trouble
finding them.
I wouldn’t mess around with any adhesives; new O-rings should take
care of it. I replaced mine a couple of years ago and have had no
problems since.

I am thinking about developing a system for electronic fuel injection on
e-types for both Stromberg and SU- carburated cars. The system shpould
overcome the problems with the new fuels, being diffrent in suimmer and
winter, boiling to soon, some times to late, always giving problems in the
mountains.
A EFI ystem with presurized fuel can’t boil, should be simple to install,
add and electronic ignition also.
Does anybody know about existing systems for sale, with their limitations ??
I am looking forward for your answers

Wilko,
I’ve thought about doing the same thing, just haven’t had time
or money. If I were going to do it, I’d use the MegaSquirt: http://www.megasquirt.info/
It’s cheap, infinitely flexible, and totally open-source.
There’s also a modification, MegaSpark, for handling ignition. I’d
love to see a ‘‘stealth’’ system, that inserts the injectors
underneath the intake manifold, leaving the SUs there just as
throttle bodies, so the engine would look completely stock.–

The Electromotive system has been used with success on V12’s, and perhaps
some 6’s. There’s a hierarchy among EFI computers: stuff at the top of the
heap have all sorts of advanced tuning tools, and are priced accordingly. .
At the very bottom in terms of price are do it yourself systems, whether
scratch built (like Bruce Bowling’s Megasquirt) or reconstituted from
existing cars. Look up SDS or Wolf for a compromise ECU at a relatively
low cost. Note that in addition to the computer, you will need a wiring
harness, fuel rail, injectors, a high pressure pump, a high amp alternator,
and a brace of sensors. Cheap is a relative term when discussing EFI. Any
of the available ECU’s will do what you want, it’s just a question of how
well, and how easy they are to tune.
Remember that in addition to all the hardware, you will need some serious
dyno time to dial in your system (as well as a laptop computer). Finally,
you’re going to get better advice on this topic through the diy-efi mailing
list at http://www.diy-efi.org/ . Here’s a list of EFI links, it’s not
exhaustive.

I noticed in this months Classic Motorsports magazine (Jan
2005 issue) there is an ad from a company selling EFI
throttle bodies that bolt in place of SU carb bodies. The
company is TWM Induction (www.twminduction.com)
I don’t know anything about them but the stuff in the ad
looks like a neat product idea. This doesn’t give you the
ECU or wiring part of the equation but it is a place to
mount the injectors easily.–
