Just got a SVO, it's my first turbo car. Will I lose power if I put a blow off valve on?

A BOV will work, but it is not an ideal application for a mostly stock car. When you lift off the throttle it releases air into the atmosphere that has been metered by the VAM, resulting in an extremely rich condition when you hop back on the throttle. You should use a bypass valve (BPV) instead which vents the pressure, but recirculates it back into the system avoiding the rich spike.

If all you want is the sound of the BOV, then you won't be happy with the BPV since it has a much quieter "whoosh" sound than the louder "whistle" noise. If you switched to a speed density or megasquirt system then a BOV would work fine.

Yea it's stock, but I'm a sucker for the blowoff sound. How can I get it. What mods would I do, in order to not have problems.

The easiest method is to buy a dual piston BOV design, such as the one sold by Stinger:

I can't offer any insight as to how loud it is compared to a normal one, as I prefer the sound of the stock setup and have never used a BOV on this car.

According to a random post I saw on TurboFord the dual piston Stinger BOV sounds similar to the one equipped on the car below:

Although that car is pushing 300 hp, so it is probably sounding more aggressive than yours.
