2L Zetec peeks at about 85mph.
I have a 2L Zetec fitted with twin 45 Webbers in my Tiger Avon which I had set up at a local garage but when I put my toe down, at about 85mph it
doesn’t seem to want to go any faster than 85mph, I have a fuel filter fitted near the fuel tank which I have only recently fitted and before I fitted
this it was quite capable of doing well over a ton.
Could it be fuel starvation or is there another cause?
Regards
Steve

Take the filter out and see if works again?

Sounds like you already know the answer to this one.
A few years back I made up an air filter system for my car. It looked well trick. I did a track day and theing did not want to pull past about 6k. I
took the whole lot back off and rund with no filters. The thing was mental! Did a propper pipercross sausage set up as soon as I got home.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

What type and size filter did you fit?
Carbs like that will be liking a lots of fuel at low pressure.

What filter did you fit and did you fit it the right way around ? (Sorry don't mean to cause offence but have seen it done)
Are you using a fuel pressure regulator ? and what pressure is it set to if hopefully you are ?

Hi Gents,
The type of filter I used is the clear nylon fuel filter, which I believe gives a max of 10 psi pressure. No fuel pressure regulator is being used.
Think I fitted it the right way round but perhaps I need to re-check but then again if it was fitted the wrong way round would the fuel still go
through?

You must use a regulator with Webers. Most pumps supply at approx. 6 psi and the needle valve in a weber can only cope with 3 psi approx. This will
not be causing your problem but once the filter issue is sorted get a regulator fitted and take it to a rolling road to get it set up.
