Hi guys,
I'm just wondering if it's possible to make my turbo flutter, I had a dump valve on and got bored only the pssshhh noise and want to make a flutter noise like my friend with a VXR, is this possible with an mr2? And how will I go about doing it? I'm currently swapped back to factory recirculating valve
Thanks

Re: Turbo Flutter
Just block off the recirc valve/ dump valve port and you'll get the flutter. I've done the same with mine. Sounds awesome. Lots of controversy around it though.
Here's a couple of old threads from a quick search (plenty more info about on the net if you wanna research it some more)

Re: Turbo Flutter
Either remove or disable the factory blow off valve. You will get the flutter on throttle lift and between gear changes.
Factory blow off valve/bypass valves are fitted to suppress noise and for emissions. Many vehicles are not fitted with them. The ST185 Celica GT-Four, as an example, was never fitted with one from factory and that uses the same engine/turbo combo that the 1989-1993 SW20 turbo is fitted with.

Re: Turbo Flutter
I had some cars thats loved running bov-les .. the mr2 is not one of them .. tried it with my ct20b .. car hated it .
Just my experience and thoughts
Ps. I was running 15psi+ .. if your only running low boost you might be ok .. still woundnt recommend it .

This conversation is always good!
Some are for, some are against. Good points made in both camps it seems. Personally, I will be going BOV-less, but to each his/her own.

Every car is different thats the problem, my car hated it (going bov-les) your car likes it .. as long as your not losing performance .. who cares .... ran plenty of cars with no bov , love chatter/flutter
Re: Turbo Flutter
Blocked my bov off ages ago
On a ct20b hybrid must have easily done over 10k by now without any issue. Sounds great and throttle response is better between gear changes.

Re: Turbo Flutter
I've ran a Bov and it likes it everything runs fine and I've just recently put the standard one back on and shifting is so much smoother!! And all I want now it to make that flutter!! :')
Re: Turbo Flutter
go for an adjustable BOV that way it'll dump under high boost but flutter under low boost

Re: Turbo Flutter
Where do I get one of these that fits my car?
Re: Turbo Flutter
Am I correct in assuming that you could remove the vac line from the aftermarket bov, block one end then block the bov end with another vac line?
That way the bov wouldn't open at all so remaining permanently shut..?
EDIT: Read the other thread, my bad.

That will work on a hks style valve because the more boost you run the firmer shut the valve is .. other valves the spring can be over come by boost with the vac line detached.
Re: Turbo Flutter
Nice one cheers.
I blocked the vac line off, does flutter but not the familiar Nissan flutter or similar. Any of you guys got clips of yours?

You can hear mine in this video - https://www.youtube.com/watch?v=IwjW9eEUdt4
I'm running completely bov'less.
Re: Turbo Flutter
Nice one sounds good. I'll try get a clip of mine and see how it is in comparison.
Do you have a block off plate?
I run mine for two days and just felt sorry for the turbo haha.

Re: Turbo Flutter
Ye, I got one of the RacerX block off plates.
I've been running it for about 18 months, ~5-6k miles with no issues, so far.
