RS2000 Posted January 21, 2013 Share Posted January 21, 2013 Has anyone hooked up an old 'hoover' hose or similar to their 7's exhaust to enable them to run their engine whilst in the garage? Any tips / ideas? Link to comment Share on other sites More sharing options...

Jonathan Kay Posted January 21, 2013 Share Posted January 21, 2013 Please use a carbon monoxide monitor if you do this or something similar. Jonathan Link to comment Share on other sites More sharing options...

Baz Hemsley Posted January 21, 2013 Share Posted January 21, 2013 Yes do it often. Connected via old bottom rad' hose stuffed up the end. over rev' and it blows out the end. also pipe gets very hot, care needed when removing it. mainly used to reduce exhuast noise so not too upset local residents, when balancing carbs.

Roger Ford Posted January 22, 2013 Share Posted January 22, 2013 I rather foolishly thought that having a catalytic converter meant you were safe from carbon monoxide when running an engine in a garage. But of course the cat only works when fully up to temperature, so there's a good long period when you are chucking out lots of CO. And a fair chance that your cat doesn't work anyway.

LesG Posted January 24, 2013 Share Posted January 24, 2013 There is a firm who produce a coil-reinforced heavy duty hose, with a rubber cone at one end (for you to place over/near tailpipe), and has a connection for your compressed airline to blow air through inducing a venturi effect, which then sucks your exhaust gases out the other end. I'm sure it is a British firm, but I'm struggling to remember their name Link to comment Share on other sites More sharing options...
Stationary M25 Traveller Posted January 24, 2013 Share Posted January 24, 2013 Most hose suppliers will be able to supply exhaust extraction hose. Pirtek would be a good place to start. If you are struggling to source it, let me know, I have spent 15 years dealing with a lot of hose suppliers. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted January 24, 2013 Leadership Team Share Posted January 24, 2013 What about an inline fan such as the Vent Axia ACM100 which will fit in a simple 100mm flexi ducting. It's rated at 220m3 per hour ... my calculations suggest that at 1000rpm tickover a 2L engine should emit 30m3 per hour. Stu. Link to comment Share on other sites More sharing options...
Area Representative Golf Juliet Tango Posted January 24, 2013 Area Representative Share Posted January 24, 2013 Stu, I agree with that approach (I'll just accept your figures). You need to have an established zone of reduced pressure before kicking the engine into life. Jonathan, you, too, are right. More information is better.

diggerman Posted January 28, 2013 Share Posted January 28, 2013 I use a length of flexible stainless chimney liner. It is about 4in dia so is a loose fit over the exhaust but interestingly that creates a Venturi effect so that fresh air is sucked in the gap, thus keeping the garage air clear. I locate it to the exhaust using a short bit of coat hanger wire with a hooked end that attaches to the bobbin bracket. Peter Link to comment Share on other sites More sharing options...
