These are easy and cheap to make but for those who don't have access to the neccessary bits and pieces is there any interest in bying pre-built boost leak testers? Looks like this very easy to use, plug one side into your intake pipe and connect and air compressor to the valve. Thread sealing tape is wrapped around the edge for a nice tight seal. I have a ready supply of tyre valves so I can make them up relatively easily. Not looking to make any $$ but I figure there are probably a few people who've been meaning to get around to this and haven't for one reason or another, is anyone interested in buying one if I put them together and sell for $5 plus postage? Open-ended offer, I couldn't really think of the most appropriate forum.
well done rob ...!!!! looks very similar to the one i knocked up and have distributed recently to a dozen or so gold coasters .. plus one sent to keza .. known up here as "black baz's u-beaut blower uperer"..!!!! ..colour coded to their zed colour ..!!! what did you use for the base ..?? i used extruded pvc .. and am thinking of trying 80ml cork, cos it's lighter, for my next batch .. must say yours looks a better finish than mine ..!!! :thumbsup::thumbsup::thumbsup::thumbsup::thumbsup:
One for me, too, please Rob It'll save me a 150km round trip to see Wykked. (And that's without leaving Melbourne) (But I'll still go there for social occasions!)
OK great I'll pick up some more tyre valves I've just used the lid from a jar of "No Frills Skin revitalising cream" -fairly cheap and I knew it was going to be a good fit after using Wizard's blower-upererer made from a "home brand" skin cream container. I'll pick up some more tyre valves and PM people as they're ready to go.
Blow up tool Rob, I made a very crude one and I am intending to make a proper one from the base of a small fire extinguisher. My question is that there is no way that you can pressurize the induction system up to 10 pounds and then watch for leakage because valves will always be open, so do you only listen for escaping air while pumping air into the system or am I missing something.
Pressurising the system Black Knight TT, short answer is I cab't answer your question hopefully someone else will jump in. I can tell you from experience testing my own car and watching a couple of others get done that once you've plugged your inlet T-piece with the tester (just disconnect your AFM), hook it up to a compressor (the portable kind that you use for tyres is usually good cause they have a PSI guage) and pressurise away. When you turn the compressor off any boost leaks will be clearly audible as the air excapes, much like if you pinch the end of a balloon and let the air out slowly. In my case 10PSI wasn't necessary but it is generally accepted as a safe level 'cause 10 pound of boost is very safe to run. A good article from the tech section HERE that might make for helpful reading.
Re- Pressurising system This was one of the things I asked Mark (Zed4life) about at our Dyno day. Given that we have considerable valve overlap, when the engine is stopped there is a good chance? that at least one cyl. will have both exhaust and intake valves open to some extent . How then do you pressuruse the system? Somebody shoot me down here!
I havn't to date been able to hold pressure in my system... And to date I'm still hunting down god damn leaks :angry:
