Just seen this on Youtube
Mighty Car Mods - Blow Off Valves Mythbusted (SE02 EP03)

What do you think? apparantley no power loss with an atmospheric dump valve?

I'm part of the turbo charged gang :grin: haha and love it!
Thats an interesting vid
-
why would you want to install a bov on a non turbo, just buy a turbo car in the first place :laugh:

just look how badass they looked in that daiwoo with the dv value :tongue: :grin:

It makes sense about performance, and like he said, more modern engines don't really suffer from a great deal of lag anyways =]
BOV's ftw :evil:

dont be a woofta!

Dont think the arguement has ever been about power loss while installing a BOV.
When accelerating power will always be the same as video explains as both valves will be shut. What problem is on 1.8Ts is changing gear and metered air.
I have one fitted and the arguement against, which im pretty sure is correct, is that when you change gear, BOV vents to atmosphere which means less air in system, so over fueling happens for a short time after gear changes.
For those with new engines :laugh: (mines AGU) you have 2 sensors, MAF and MAP and these must have similar air readings or will throw the ECU into limp mode?
I have tried,
007p cheap copy - spring was too weak, didnt get new one.
Baileys DV20 - doesnt work, needs to be twin piston.
Baileys DV26 - works OK on my AGU IMO. lots will disagree.
Forge 007p - works great.
The dual piston valve works, i think, by only letting air vent to atmosphere under load, where as the DV20 or single piston ones vent to atmosphere as soon as throttle is released, and from my experience with AGU, this causes car to stall and run really rough.
Plenty will say what im doing is wrong, and messing my car up i expect, but this is all from my experience, on my car.
Im happy with how everything runs at the min, but i will be putting 007p back on for when i get to stage 2 as 1) R-Tech dont like them :laugh: and 2) bored of the woosh :grin:
Let the grilling commence :laugh: :grin: :lipsrsealed:
-
i have a forge split r type which i can have as blow off or full circ, no issues at all, cant even feel any differance between them, i have an agu with a stage 1 remap at 197bhp

Knew you wouldnt like this thread rich :laugh:

The only problem is that atmospheric dump valves sound uber gay on golfs. My 007p makes a row with my CAI but it doesn't sound as bent as when I tried a baileys one the day I bought my car (pre forum.....) might have to get a black front wing though to set the trend! :grin:

Just wondering, with the 007p, what % of the air actually recirculates, and how much goes back through CAI and vented to atmosphere anyway :lipsrsealed:
