Webber/elderbrook or efi?

[numbnuts]

I am just doing a bit of research and the webber/elderbrook carb/manifold kits seem quite cheap..I just wondred if there would be much power gain over the standard RV8 efi..

Nope. Just monetary loss via initial purchase and ongoing fuel costs.

Cheap? I must be a real tight git, as I tend to think £500+ is not cheap for a carb and manifold.

Ebay had some at £650 last week, brand new complete kit, with filter, studs, etc, but also the same kit, same seller, at £550 further down the page.

Buying the carb and manifold individually comes to £480 and change.

Not cheap.

Unless you know something (or somewhere) I don't....

There is a power gain over the stock efi system, however if you were to pay the expense of having your efi mapped then that would win....... and so on!

V8 tuner.com..i think they were £500 inc vat and all bits and bobs and air filter.
The trouble with the efi set up is they do tend to go out of tune, carbs are much simpler...
I will wait till i get to the top end i think and make a decision then,;confused: got to re-shell it first.

How do you work this out?
Electronic parts dont move, the only things that could be wrong maybe the TPS settings and the like.

A carb has things to wear, vibrate loose

ok fair point, lets just say they are a bit easier to set up.
IMHO

Bugger, thought we were really going to get ourselves into some trouble then...
