GROUP BUY Pressure test kit for S2/RS2/S4/S6

[Lee]

Hi all,

I have been in discussions with a manufacturing workshop and have secured a special price for pressure test adapter for the 3B, ABY, ADU, AAN engines and is also compatible with many others.

The part is an adapter to sit in the intake hose that connects to the airbox. The adapter interfaces to any compressor via a regular tyre valve. The adapter is made from Delrin so it is lightweight and compatible will all fluids around the engine bay. The tyre valve interface is included in the price.

This adapter is essential for anyone wanting to check the integrity of their own intake hoses. We all know that a boost leak will not only lead to reduced power but also will cause the turbo to overspin trying to generate the ECU demanded pressure...the result is a rapid demise of an expensive turbo. We don't want that! This test is also very important before a car is remapped or 'homefried' as it allows an easy check for boost leaks in minutes. Just connect to a compressor, pump to 2bar or so and listen for the hissing. It will even pinpoint if the oil filler cap seal is working effectively as well as other crankcase breathing equipment problems.

If I can get 25 names together for this kit I can supply them for £11.75+Vat delivered to the UK. For overseas enquiries contact me by PM so I can work out the extra shipping charges.

These adapters are available in Europe for much more money so here is your chance to get one cheap. If 50 people are interested, the price somes down to £10.20+VAT delivered. Hard to beat I think. Outside the group buy they will be available for £15+VAT delivered so get one cheap now!

PLease state your interest by posting here or sending me a PM and I will update everyone on progress. I need to commit to these beofore 15 November to get this excellent price as there is workshop capacity available now.

Thanks for looking

Wow, 5 already...lets see if we can hit the cheaper cost break, only 45 more to go!!

[Greg_S]

yup, one for me too

I have been making a few of these to people who have requested them, (getting 90mm Polypenco bar is becoming a biatch though ) they are a great idea and at that price well worth it. My only concern is putting 2 bar into the crank case, couldnt this blow out an oil seal, i plug the breather line off as that MAF-Turbo hose doesnt normally see positive pressure. To illiminate valve leakage i plug off the pipe before it goes into the metal intake pipe over the exhaust manifold, just to isolate the turbo system from the engine. You can also test the recirc valve if you unplug that from the MAF-Turbo pipe and plug of that connection leaving the recirc valve to dump to atmosphere (all being well at the correct pressure).

pressure tester

[count me in for one as well . tell me how to pay

[Lee]

That is an idea. I have used these testers directly with no issues and it actually highlighted a leak in the oil breather system too on mine. Getting a bung made for the metal intake pipe would be cheap enough but even if you do that you are not testing the throttle body to intake pipe hose. I know Tom has blown a few of these so it is also worth testing! It is also worth testing the MAF to turbo hose as I have seen these split with age causing incorrect mixtures.

What crank case pressure would you expect to see on a tired 5 cylinder engine running 1.5bar+ boost pressure with a 9:1 plus compression ratio with a standard breather system? I am sure it must be approaching 2bar+ dynamically.

The test only takes about 30seconds so I am not sure whether the crank oil seals would be at risk. Their area must of the order one square inch and it takes more than 30lb to push them out I would have thought.

If anyone is concerned and wants extra bungs they should be of the order £10 each or less. I will make some enquiries.

[Pete_RS2]

Put me down for one Lee.

[Lee]

Cool. So, would people be interested in the extra bungs? I am sure they should be quite a bit cheaper than the adapter since it doesn't need a thin wall for fitting the tyre valve and could therefor be solid plus it is not an assembly! It would be smaller barstock too. We should be looking at around £20 or so for both the adapter and a bung. Let me know guys.

Lee,

I'll have an adapter and a bung if that's the recommended kit

[s2avant]

Yup, I'll take one and some bungs if they are being made too.
