Mark,
I discussed this with Alan Dean and his response was that he had looked at all the options and the Gauzes met his specifications. He was the expert and I can only assume his design deliberately did not allow clear airflow to bypass the Gauze so that any and all petrol droplets would encounter the Gauze and go through the atomisation process ! Of course some small droplets will get through however in the main the Gauze will achieve it's objective.
I'm not however dismissing your idea in that I would guess that for the petrol droplets to fall the distance to the type of Gauze (ie. similar shape to the Ford 'W') your suggesting would then limit/restrict the time that the petrol would have to undergo the main reason for introducing the Gauze concept in the first place ie. The surface tension properties that allow the petrol to cling to and then be atomised by the airflow across the gauze. An interesting option or possible alternate solution may be that the 'W' be inverted (ie. up into the two feeder holes from the Carb) but IMO I still don't think that it will be as efficient as Alan's gauze design.
Regards,
Viv

Gilles,
Not yet but awaiting call from Tony in Southampton as his SE6b 2.8, to which I fitted a set of Gauzes to on Tuesday 26th Dec 2011, is his everyday car. His response so far has been very similar to Mikey Bikey's and was expected !
Regards,
Viv

i just bought some mesh and didn't think about size ? The fuel guage is the only electrical item that doesn't work (due to a broken sender) so at the moment can't do mpg very well. The problem is , the car runs SOOO well and the engine so strong that I'm using the power :D so consuming fuel quite quickly :( . Good fun though and sounds terrific

Happy that you enjoy your car Mikey !!!
Just ordered the complete kit : gunson colortune, accuspark and timming Strobe, just missing the Gauzes.
Form here the only mesh I can order is the #16 http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0627064481
It is maybe fine :?:

Has anyone managed to do a rolling road comparison yet?

nothing scientific here, seems that I gain a little on MPG 19 to 22.
But the car is definetly smoother.
Need to do other jobs to really tell.

Hi All,
Latest Update is that Alan's 'HSCC 70 Series' SE5 Race Car ('Jim') is putting out 158.9BHP on the rebuilt engine with the Ford 'W' and because it took some three Hours on the 'Rolling Road' to get it setup there was not the time nor the money to then install the Gauzes and retune. Alan will very shortly install one set of the Gauzes into his previous SE6a Racer, and now his everyday car, and will then check the Power/MPG figures. Not really what I was hoping for but ... to be updated !!!
Regards,
Viv

Shame I was hopping for a set of direct comparison figures to prove the gauzes one way or the other. I'm not sure how much of the reported improvements are the gauzes and how much is the due to the carb being serviced while it's off.

Steve,
Yup - my thoughts exactly !!! I will badger Alan to get this done asap on the Race Car as I think he is losing out on performance gains and this will also affect my times which is not acceptable ;~}

Just a thought, but as its a reasonable outlay of money and time for a dyno comparison. perhaps we could have a donation set-up to pay for a RR session for Alan (or anyone else for that matter). I personally wouldn't mind putting some money towards it!

Or, is there any 'spare' cash form the membership fees that could be used against this?

As I say just an idea, but this has got to be one of the most interesting and debated threads on the forum, I think its time we did some scientific testing!

I would happily do it but my scimitar is currently 600 miles away and is awaiting its drive-train being put back in for its maiden voyage.
