Alright, let’s talk about the Mach 2 valve. If you’re into turbo cars, you know how important it is to have a solid bypass valve that actually does its job. The Mach 2 is a straightforward, no-nonsense upgrade that fits right in without any fuss. Seriously, it’s a bolt-on deal. Just pop off your factory bypass valve and slap this one on—no extra parts or modifications needed. Easy peasy!
This valve is set up as a 100% recirculating model, which means it’s perfect for those who want to keep things quiet while still getting that performance boost. But if you’re feeling a little wild and want to hear some sweet turbo sounds, you can grab an add-on kit to convert it to vent to atmosphere. It’s like having the best of both worlds!
Now, let’s get into why you’d want to ditch your stock bypass valve. Most factory valves have a couple of major issues. First off, they usually don’t start opening until you hit a certain pressure, which can leave you with lag when you need it most. Plus, they’re not really designed for quick throttle response. And don’t even think about venting them to atmosphere without risking a stall—no one wants that headache.
The Mach 2 changes the game. It can handle all the boost you throw at it—seriously, no turbo is going to break this thing. Thanks to its TMS technology, you’ll get lightning-fast throttle response, which is crucial when you’re pushing your ride. And if you do decide to go for that atmo conversion, you can vent without stalling your engine. That’s a win in my book!
Here’s a quick rundown of what it fits:
With a 35mm inlet and a 30mm outlet, the GFB Mach 2 TMS Recirculating Diverter valve is designed to fit snugly and perform reliably. If you’re looking to enhance your turbo setup, this valve is worth considering. It’s all about getting the performance you want, without the hassle.
