Cold Air Intake for Dual Carbs?

I was reading through the forums and I myself have experienced the vapor soak/heat of the engine bay. Is it possible to create a cold air intake on a speedster? Relocating the filters to the wheel wells, creating an airbox around each carb with cooler air entering the box only? Also cooling the fuel bowls to help with the "hard -hot engine starts".. Just a thought.. Id like to know your thoughts..

It's not the air intake, it's heat directly on the fuel line. You probably have a fuel line too close to a heat source that's causing the fuel to boil - hence the term "vapor lock". Make sure your fuel lines don't sit on the tins over the exhaust system or heater boxes. You DO have the tins installed, don't you? How about some pics of your engine? That would help us diagnose your problem.

I am looking at a picture with the caption , "1958 Carrera Speedster GT with cold air boxes that envelop the air cleaners"(Porsche 356 and RS Spyders, by Gordan Maltby).

The picture shows the metal inner panel of the rear deck lid has been specifically formed to fit around the air cleaners and sealed with a foam gasket to the air cleaner base. Air enters the rear deck lid via large louvers to the left and right of the standard air grille. This air is ducted directly to the carbs. I presume (but don't know) that the carb air is kept separated from the engine cooling air, which enters the central air grille as on our replicas.

I've seen several of these setups, especialy at Vintage racing events. Does that make any difference on a street driven vehicle? I can't say, but I do like the look and copied it, minus the structure under the decklid. I like louvers!

Here is a picture of my bay

David could you attach a picture of that? thanx in advance

Definitely check your fuel line locations to be certain they are not picking up any additional or inadvertent heat as Lane said. Good time to check that oil lines aren't in jeopardy (like resting near a muffler/header, eh Bruce?) either.

As for cold air to the carbs; I'm a big fan (no pun intended). There were discussions some time back about whether the carrera-style louvres actually pulled air in or let hot air out based on their orientation.

I had air coming in off the rear deck and funneled directly at the carbs. I figure any 'blow-by' went out the louvres and took hot air with it.

The enclosed cold air boxes on Carrera engines were interesting looking.

Scott, sometimes it's a good idea to move that fuel-filter to the front of the car, under the tank - safer and better for a number of reasons.

Scott, basically I think you need someone to look at the car and re-route fuel lines, filters, check the tins and their sealing surfaces etc etc. Possibly do a tune up and check other components of the engine. Looking at a photo with an explanation of a problem is OK but so much better if you take your car to someone who knows VW engines.

This set up (VW) is common with 99.99% of the people that post here, 98% of them have no problems so, something is unique in your engine compartment and, it can be solved.
