So this is the first "new" turbo car I've owned and curious if anyone has tried to put a blow off valve in it yet. I was looking at an HKS SSQV (classic and I love the sound) but not sure if its smart to put one in or not.

The Trailblazer has an electric wastegate system. How would you integrate a spring loaded blow off valve? As you probably know already turbo engine produce alot of cylinder pressure as the turbo spools up, so you need to be careful how high that pressure gets before you start blowing gaskets or doing harm to the engine. Adding a blow off valve will also completely void your warranty.

Thanks Steve, I don't have much experience with turbo engines. But ya, not looking to void my warranty. Makes it easy to decide against it. I just wanted that bov noise. Oh well!

When I swapped out the stock paper filter for a K&N and removed one internal baffle inside the air box on my 2012 Cruze the factory blow off valve was suddenly more noticeable. For those who don't know the Cruze also made in Korea had a small 4cyl turbo engine. After I added a cold air intake the noise became even more noticeable. Factory air intakes usually have baffling and chambers designed to control or eliminate certain noises. I also like the sound of a blowoff valve just like I like the sound of a good aftermarket exhaust system. I enjoy "hearing" what the engine is actually doing vs relying on gauges to tell me what's going on. Hopefully the aftermarket will catch up and start releasing products for us to customize our Trailblazers the way we like.

I am not sure what is happening with SEMA this year, but I am curious to see if some companies will have any custom TB's on display. Going to this show is one of my bucket list items.
