Does anyone want to sell there Forge BOV for cheap or realatively cheap with the install kit?
 
Here at Forge, I have 3 slightly used (no more than 50 miles) kits available for resale if you are interested.

They are available in Blue, Black, or Polished.

All of the valves have been completely cleaned and serviced, and supplied with new hoses and clamps, so they are as good as new. Only a few slight scratches from the previous installation.

Let me know if you are interested.

I have one of your polished BOVs...is there any way I could swap for the black one? I'm not a fan of chrome. Mine is in great condition & I only need the valve, not any of the other stuff.

We don't offer the valves for trade. These valves were returned for a refund after being installed on a different vehicle that is not 100% atmospheric BOV compatible.

There must be some sort of operational problem with the valve for it to be returned and inspected before a replacement will be sent out.

what do you want for the blue one? Im also just crious I wa reading


One last comment then I will step out.
Slight school lesson just for those who don't know how this stuff works.

Again this is a MAF based intake system. This means that the air is metered before the blow off valve. When the air passes through the MAF adaptor the volume of air is counted and relayed to the computer. This information is then used to calculate the correct amount of fuel for the injectors to release into the motor. When the blow off valve vents to atmosphere it released air, which has already been metered. This means the computer is making calculations on air fuel ratios for air that never enters the motor.
When your BOV goes off you will see a drop in stoichiometric air/fuel ratios because the computer thinks more air is entering the motor. The result is a low stoichiometric air/fuel ratio loosing horsepower. In extreme situations you can get "fuel wash", a condition in which excess fuel washes the oil film from the rings and cylinder walls. At this point metal-to-metal contact occurs and scuffing can take place. This condition is similar to a dry start.

When a BOV recirculates the air is redirected back into the intake at a point after the MAF sensor. The result is that the turbo remains spooled while briefly recirculating the air through the intake system and slowing the ingestion of new air through the MAF. Keeping air fuel ratios correct and the turbo spooled.

Not all cars are alike. A MAP sensor based vehicle with a sensor after the throttle body (example any Honda) CAN run a vent to atmosphere BOV with no issues at all. Sorry, I know it is not fair.

Yes you can run a vent to atmosphere BOV if you NEED the sound. But the higher the boost levels and higher the horse power the more of an issue this is. Especialy those of you with aftermarket turbo kits with additional injectors in the intake tubes. Be carefull!

Hoped that helped a little. I am not a perfect person. If anyone thinks that I have explained this wrong or have provided miss information please correct me.

Thanks guys.


Now I was wondering how this BOV actually works....does it perform better than a recirculating valve? Is this gonna hack my power? is it beneficial? or is using the diverter valve actually the better way to go?

Your explanation was dead on about how these systems work. Good job on that!

With most vent-to-atmosphere blow-off valves, the stalling issue and rich fuel condition happens at idle, when vacuum is pulling the piston open venting the metered air.

Our valve is a dual piston design. At idle, vacuum is pulling the main piston open, however, the secondary piston remains closed since there is no positive boost pressure on the valve. Having this secondary piston closed causes no metered air to be released from the system. Our recirculating valve is just a direct replacement for the stock valve but is able to withstand higher boost pressure while still being as quiet as the stock setup.

As far as performance goes, you won't lose any performance or drivability with the atmospheric valve or our replacement recirculating valve, nor will it do any harm to the engine or boost systen in any way. These valves won't physically add horsepower, but will be able to handle higher boost pressure where the stock valve cannot. They will also give slightly better throttle response and spool-up time of the turbo.

Please e-mail or call me for pricing information on these units!

thanks mike....Im probably gonna go with the re-directional valve....It just sounds like the better option for me..... To many my car stalls, RPM drops and what not and I havent heard anything bead aboust the re-circ. valve.... Ill definately be ordering one.... or my girlfriend will at that matter!

thanks for your support its awesome
