After scouring these threads I opted for Oxspeeds' BOV spring. http://www.oxspeed.com/app/site/main/? I saw the JCW version and others and there didn't seem like alot of difference (except prices) Oxspeeds' is $10.+ shipping.

Came today, took about 20 minutes to install and there are some noticable differences in driveabilty of my CMS. First, throttle response at low end (A/C off) is better. There is a much quicker response between gears - zero lag. But the biggest improvement I've noticed so far is low end bog is gone when A/C on from a dead start. With the stock spring, A/C on from a dead start there seemed to be a dead spot/small hesitation, this car has barely 2k on it & I attributed that to A/C load on engine just off idle. Well the new Oxspeed spring cured that and will know more after the weekend.

Thanks Rick at Oxspeed

 

Ordered one! Hell, for ten bucks I'll give it a go!
Thanks for the post!


P.S. Does it come with install instructions??

 

This is good to know! I've killed my CM 3 times this week not giving it enough gas with the AC on. Really, part of it is the AC and part of it is that it's been 100+ degrees here and the heat soak is pretty bad. I'll get a bigger intercooler one of these days.

 

Mine didn't come w/instructions but there's instructions in multiple threads here or ask Rick (from Oxspeed to include them). It's pretty easy, just remove tube from turbo to air box and it's to lower right side of turbo - (3) T30 screws. Tip: do it when turbo is cool or those screws will be too hot to touch.

 

thanks for the write up. for $10, i might order one too

 

Here is a write up from Alta, for install if anyone else plans on purchasing one!

 

Good to know this improves low end response. I hate how sluggish the car is from a dead stop. Trying to pull out into traffic can be scary.

 

nice sounds good. btw i see that the r60 is listed for accessPORT, is than wrong? http://www.oxspeed.com/app/site/main...E-B16FD4EA2E9F

 

It says it's just a replacement dongle, whatever that entails.

Ordering a spring now. Ordered one for my wife's car too, because why not for 10 bucks.

 

Argh, they don't ship to Canada. :( Contacted them. Hopefully they'll respond soon.

 

Any more feedback on this? Particularly ads it relates to low end/startup responsiveness?

And would this be duplicative if one had an aftermarket blow-off value (e.g., Forge)?

 

Mical: How long did it take to get your spring once you ordered?
Thanks!

 

52804x4, did you get an email after you placed your order? I have a pending charge on my credit card, but never received any confirmation email.

 

It took about 2 weeks. They were out of stock when I ordered - shipping is actually about a week.

 

Yes, I received an email almost immediately after the order was placed.


Thanks!

 

The pending charge on my credit card disappeared, so I placed another order today. Still no email. I'd better call tomorrow and make sure I don't end up with a dozen of these things.

 

Can someone explain exactly what this does?

Thanks!
Kyle

 

I did some research and figured it out, mines on order now

Thanks for the great tip!

Kyle

 

Care to post/share what you found? If it improves low-end acceleration, I'm all for it. Otherwise, I am weary about tinkering with the turbo.

 

There's a bunch of discussions here:

Great tip, thanks! I ordered one today...

 

Oxspeed or alta?? Are they the same?

 

Has anyone who ordered received theirs yet??!!

 

Nope. I was thinking about emailing them next week to check on the status, but I guess I'm not the only one.

 

I ordered one as well. It has been about 10 days now. I emailed than after 5 days about my order status but never recieved a reply. So I called 3 days later and left a message. I was finally emailed a message saying that they were out of stock on them and that mine "should" go out that day.
