This is great but really interests me is this from your recent email:

Coming Soon:

Super 20G Turbo Upgrade for GXP & RedLine!

Anything to tell us about this? Will it be an install from your shop only? How much hp increase will this upgrade be? Will this be a part of a kit with other upgrades? any internals? Will this kit include this BOV?

The S20G Turbo Upgrade is almost ready to debut, yes!

I will be posting a new thread about it soon....I don't want to get too specific right now until we've finalized all details. Yes, this BOV system would support it

Shoot... I bought this intake. I guess I'll need a new intake to get that BOV.



I guess the intake from Dejon would work? Does it sound a lot different than the stock diverter valve?

Actually, one trim to that intake tube would make it work. Easy!

And oh yes...it sounds MUCH different than stock valve!

Great looking product!!

But, I thought that as the RL is setup for the Diverter to pass gas back into the intake that an external release would be bad or at least lead to codes being thrown by the MA sensors???????? Help me understand!!!!

You are 100% correct...this is why we use a recirculating valve that directs the bypassed air back into the turbocharger inlet:

so basically this does the same thing as our stock cbv?

Functionally, yes. It just does it in a more effective way via enhanced flow and adjustability.

what does the adjustability do? what are you increasing/decreasing?

By adjusting the amount of airflow bypassed, one can optimize the response time of the turbocharger during sudden throttle on/off/on instances such as upshift or spirited cornering. It is during these transitions where you suddenly close the throttle that the turbocharger's inertia creates airflow that has to be momentarily bypassed, since it cannot flow through the suddenly closed throttle plate. To not bypass this air, or to not bypass enough of it, can significantly decelerate the turbocharger, causing a momentary 'flat' feeling when you snap the throttle back open until the turbo accelerates again.

By adjusting the valve's performance, one can optimize the amount of air bypassed to suit different equipment combinations as well as different driving techniques. Everyrone hits the pedals slightly differently than everyone else, and being able to optimize for YOUR driving style can be very rewarding!

so if you increase the pressure, then it will take longer for the air to leave the valve, meaning you can take longer to shift. is that right?

That's right, if I read you correctly. If the spring pressure in the valve is increased via the adjustment, the amount of air bypassed will be reduced, which would necessitate a faster shift to avoid slowing down the turbo.

Adjustment of one of these is primarily a 'trial and error' process. Another excuse to go play with your car! You just try different settings until the turbo is immediately 'back on' after upshift. Works great!

but daily driving and "racing" are two completely different driving styles, so youd have to find two settings that work for you, right?

Not really...the setting you arrive at will be primarily based upon WOT shifting response, which is the same no matter where you do it, road or track!

There will be no setting for 'racing'. One adjustment procedure does it all, for all styles of driving.
