[Taxista]

I wanted to know which Blow-Off of the Forge goes well for our GTI modified with 250 HP? :burnrubber::burnrubber:

Either, one is adjustable the other isn't.

And since it is a spacer and not a valve, it doesn't matter what hp you have,......yet.

 

[Taxista]

Because I have felt many that after to have modified with power to 235hp, the machine gave problems to high regimes, type decrease of performances, and said that it is guilt of the first valve blow-of that it is not regisatrabile as the second one

 

[feuerdog]

The Forge SPACER is in-line AFTER the stock valve, and therefore has NO affect on immediate boost performance,..........but some have complained that some loss of power can be felt as a result of this spacer,....possibly due to a fuel trimming issue.

If you are concerned, then just get the adjustable one, and hope that you don't lose power,......or better yet, don't get it at all.

I just installed the adjustable forge blow off valve.... is isnt too loud donno why.... i put it on the loudest still dont make loud sound. Ima go chip my car 2moro and see.

 

[sniperviperman]

loud sound only when driving, try 1200 rpm's, give a bit of throttle for 1 second and release it, that should be very loud.

 

[wudaoerji]

which one is louder full atmo , 50/50 or full recirc ?

 

[GTI2007]

Normally the loudest would be the the full atmospheric one because that's the same setting as the non-adjustable Forge BOV.

So from the dyno it appears that as long as you dont use Full Recirc you should be ok, although it doesnt have a stock line to see if there is any actual power loss.

I was curious I see dynos charts for the adjustable Forge DV (100% Atmosphere, 50/50, and the 100% DV) When you just buy the unadjustable Forge spacer what is it most like??? Is it 50/50?? Please let me know I am really curious.....

 

[Mike@Forge]

Here's a simple break down:

Non-Adjustable

Fully vent to atmosphere 100% of the time

Adjustable

Fully Atmospheric (just like the non-adjustable version)

50/50 (half vent to atmosphere and half recirculated)

Fully Recirculating (All air is recirculated, just as if the spacer wasn't even installed at all)

I'll go with Forge's Adjustable one, I can always make it louder or softer. I like new toys.
