Vince Saiya of Stealth Racing specialises in tuning performance GTi's and got in touch last year because he had heard of the CB-26P and was a bit sceptical. To cut a long story short after some thorough testing, here he is fitting it to his personal GTi 16v Turbo - blimey!

Vince can be contacted on 01926 - 812259 or vince@stealtehracing.demon.co.uk or via the Stealth Racing Web site at www.stealthracing.co.uk - see the link at the bottom of this page. He fits more CB-26P's to VW GTi's than anybody else in Britain so he knows what he's talking about and if you drive a GTi you've really got to try the device to believe the difference it makes - there's a 30 day satisfaction guarantee and Vince has never had one back!

First locate the vacuum servo pipe and cut it 3" or so from the manifold with a sharp blade. These pictures can be enlarged by clicking on them - to return to this page simply click the 'Back' button on your browser. Though it is not absolutely necessary, we do strongly recommend the use of Jubilee type clips as any air leaks could affect the performance of the device and, of course, your power braking. So you now need to check the gold body of the CB-26P unit is tight to its T piece with a 19mm spanner. Then get a couple of Jubilee clips and place them on the severed ends of the pipe and then insert the CB-26P and tighten the clips.

Once the device is fitted turn it closed and warm up the engine so that it ticks over without choke. With the engine ticking over unscrew the filter housing until the device makes a husky induction noise and close it to the point the noise stops and then close it another quarter turn or 90° from this point.

To check the unit is functioning properly rev the motor from under the bonnet and listen to the device. You should year the unit making a harsh induction noise on deceleration which subsides as the engine settles to idle. If this is the case the unit is working perfectly - be sure to check the locking ring is good and tight and you shouldn't need to touch the device again. Every 12,000 miles or so you might want to clean the valve, spring and filter with petrol. As for longevity we have had units running for 60,000 miles without any signs of wear and we've never had a warranty claim so what more can we say.

Some owners tune their induction profiles and don't much care for the rasp of the Ecotek so in conjunction with Pipercross we have developed a Silencer/Filter (click here for more details).

Now you may say, it's all very well learning how to fit Vince's fancy 16v Turbo but what about my 8v Mark 1? Well we haven't forgotten you - and remember that the Ecotek CB-26P probably makes as much difference to the performance of your 8v as any in the range. On the Mark 1 there is a breather hose that you can use that avoids the use of your brake servo and works just as well.

You will notice from the picture that the blanking hose has simply been replaced on the end of the device with a new bit of hose at the manifold end - it is probably neater to cut and trim the blanking hose but as long as the Ecotek unit is approx 3" from the manifold you can do it any way you like! Tuning is exactly the same. Mark 2. 8v Golfs have the servo connection at the end of the manifold at the back. The flexible hose is quite short and sometimes people prefer to add a bit of hose at the manifold end. 9mm fuel/emission hose and a couple of extra jubilee clips is all you need.

Now if all this is a bit much for you there is a list of Suppliers on this web site who would be pleased to fit the device for you and you can visit Vince's site by clicking this logo:
