Questions about BRV's
1.Can you use them on stock turbo's?
2.Can you use them with SPI 750 kit?
3.There are a lot of different companies who carry need feedback(6SOL).
4.Are they worth the $$$...?

 

I would stick with Forge DV's and it will work on stock turbos, SPI 750kit or any modded stock turbos.

 

Many people are going with the Audi 710n diverter. Cheap and works great and lasts. Plus no worries about lubing billet type DVs or sticking. http://www.passatworld.com/forums/81...r-pricing.html

Please verify if this works on 997. I know it works on 996

 

Okay I purchased the Forge DV's it comes with two springs one is stiffer the the other. Stiffer spring is for cars with ECU flash. My question is if I was running the stock OE values and the car runs strong. Should I move to the stiffer spring. Forge in FL couldn't answer the question. Really you sell something and you can't tell me what spring to use. Went with the stiffer spring and the car runs fine. Would have been nice to know why the include two springs.

 

Stiffer spring will help in fast shift situations where you slam the throttle and re-open it.. Also definitely better with bigger turbos.

I'm sure tuners have the best answer. Ask Markski / 911 Tuning
