a regular blow off valve will not work in this application , lets be clear its not needed either , the factory solenoid valve does the job its supposed to , the blow off spacer is what it is , a spacer to give you the blow off sound with zero issues , you either want the blow off sound or you dont ...personal choice is great ... with over 500 + solf for this applicayion I guess a few customers like it
 
techie i'd love to hear a vid of yours without the supercharger sound proofing and with the blow off valve.
 
just been reading through this thread as im intrested in the bov for my future cupra!

im confused though what is the difference between the spacer and bov?? and i have seen a product on forge website part number FMD14TSI is this a bov or a spacer and has anyone had an experience of this??

the engine is complex because of the turbo and super, so fitting a BOV not possible....

The spacer is between turbo and the factory electronic BOV, but yeah makes the sound more louder.....

One of the problems i had with the 'new' cupra was a lack of drama - it was too quiet. i like rorty snorty 'get out of my way' cars. Part of putting the drama back into my car was fitting a Forge spacer. Mission complete.:D
 
Techie have you got one fitted to your car? really want one of these but was a little put of with all the chavs on youtube saying you lose couple of bhp, i think it may have been your video race brake not to sure lol.
 
I don't believe fitting the spacer means less power - the 13.4 sec 1/4 mile I ran is 0.1 sec quicker than Autocar measured for the Ferrari Testarossa. Enough power?;)
 
Yeah ive got one, dyno'd and still producting good power. Cant see why unless its leaking why you would loose power.
 
i wouldnt imagine you would lose power, unless there is a loss in pressure maybe which can cause less spool or something maybe?? i think ill be tempted to get one just for the wooooosh lol. never had one on the lcr due to too many problems
 
i have had mine fitted for about 2 weeks now, was a right pig to fit but managable. i like it but i think it has changed the car a little bit, i dont know whether its just me or the car is a little slower to respond to acceleration? anyone had this or am i just bein stupid

hmmm see this is what i was thinking, maybe due to a little pressure loss??
