B.O.V with a wastegate????

[mattyD]

kinda new to the whole wastegate thing, just wondering if you run a B.O.V with one really? or can you get some sort of a bung and just run off the wastegate?

[micky boy]

You can use both if you want i think its best to run both not to keen on realising pressure into the system id rather it go into the atmosphere but if you want to just run off the wastgate then you can block off the vac pipe for the .bov on the inlet..Im sure people will have different views on this so just go with what you think is best

[_shaun_]

As above can run it either way some people claim it shortens the life of the turbo if u don't run a bov as it stalls the turbo blades when the pressure surges back out of the turbo. But no one can realy prove it I've done it both ways had no issues with either

[mattyD]

i havent got the wastegate yet, but from what you have been saying it would be no different if i was to take the B.O.V off now and just let the turbo chatter?

[micky boy]

Thats right

[Liam_D]

Yeah i run both with mine matey. Havent ran the SSQV for about 4months now though.

lol, so you dont run both now? do you get a bit of chatter? how do you find the response when giving it beans?

BOV and wastegate are completely unrelated but often get confused.

A wastegate is what opens when your turbo reaches whatever boost pressure it is set to run at, it allows excess exhaust gas to bypass the turbine to avoid over boosting/over speeding the turbo.

A blow off valve releases pressure in the intake system, when you take your foot off the accelerator the throttle plate closes. The air in your intake system between the turbo and throttle body now wants to escape, but the only place it can go is back out through the turbo. This is what causes "chatter" but can also be bad for the turbo, but I doubt a little bit of boost on a CT9 is going to do any damage..

lol, so many threads about the whole its bad/but there is no real evidence etc

as you said, seeing as though im only running .7 through a ct9 hybrid i very much doubt it would cause much damage if any! im sure people are running hefty turbo's without a B.O.V and have had no problems?

A CT9 should be fine, if it fucks up just buy a TD04. ;)

[mattyD]

phaha, no chance of that mate! im having a manifold kit made up for me now! if the hybrid fucks up, il just go td12 i think

[pick1]

I've been running mine with chatter for two years no problem turbo still good and sounds mint once running a decent amount of psi through it all good if u ask me

[Liam_D]

Im not running the SSQV cuz i prefer chatter, if i connect up the SSQV It'll slighty chatter but still dump all the time just sounds weird.

No difference in spool up times at all.

[mattyD]

i think i might remove the B.O.V to be honest, its only a baileys one so i doubt it would make much difference wether its there or not

and when i come round to doing it, what can i use to block up the hole on the intercooler pipes?

[Ryan-11]

just pull the vacuum pipe off the bov and block it with a bolt, leave the bov in. if u really wanted to remove the bov just block the hole with anything that fits it lol, i used a coping saw handle.

[mattyD]

lol, that could be something to think about ;)

can you get bungs or something to stuff in the hole?

[Ryan-11]

yeah u can buy bungs of ebay, just need to make sure u get the right size.

[mattyD]

aha, nice one cheers mate

i thing that would look a bit better in my bay than the end of a broom ;) lol

so i would just basically take the B.O.V out of the silicone reducer i have on the pipe and stick one of these in instead?

[pick1]

Yes mate that's it just bung it up causing full on chatter and let the good times roll chatter is the best noise ever lol
