Strombergs or Webers

[Mazzini]

Emissions-stuff aside, I think the Strombergs itself is a bit unfairly maligned.

Plus 1 to that and I no longer have a Stromberg equipped Elan.

I find a well tuned (European tune) standard Stromberg Elan a nice road car with similar top end power to the Sprint but more low down tractability, so in someways a nicer road car. It does not have the instantaneous "punch" you get when flooring the throttle in a Elan at around 3500 rpm however. Hot starting and run on after switching off is also sometimes a challenge with Strombergs with no easy specific fixes other than make sure everything is perfect and maybe the issues go away.

They can be developed to get around 140 to 150 hp with the right cams and a bit of porting but you are ultimately limited by the less efficient breathing of the siamesed inlets.

All that said, who has ever opened an elan bonnet and gone weak at the knee's saying
'core look a set of stromberg carbs' ???
I am in exactly the position of an Elan resto thats fitted with Strombergs
It will be getting a replacement head and carbs!

BTW, Rohan
My "new" Twincam uses a McCoy Stromberg weber conversion head.
(noticed your older posts).

Actually it's a McCoy built tall block, 1950cc, 193 hp 7000, 161 lb-ft 5600
10.5 pump gas CR

As Rohan says, the head is the problem that limits Strombergs.
Having said which, I don't suppose many people have bolted 4 Strombergs to an 8-port head!

Very old topic... Yes it's a port problem.
McCoy mills off the stromberg siamese ports on the head & adds a weber intake manifold.
4 individual ports w/stock "big valves" have enough capacity for 190+HP.

SAS or any of the other new weber heads should flow about the same.
