New NGR Type-S BOV testing on Eclipse GSX Incredible Whistle
Testing the New NGR Type-S on a Mitsubishi Eclipse GSX running 21psi. Clip shows both recirculated and non recirculated. Since the original Greddy Type-S was discontinued due to problems such as leaking, weak diaphragm, etc. We have come with a new solution, I have always loved the sound of these. So we decided to make them with better internals causing no leakage, lasts longer, has a better diaphragm than the overpriced 80 dollar Greddy Type-S diaphragm that leaks easily, and it has an amazing whistle. This new diaphragm is not those cheap knockoff ones, this is a more durable, stronger, long lasting diaphragm that will support any Boost level. This will be for sale on eBay soon, because we are new to selling on eBay, we will be offering it real cheap starting at $99.99 plus shipping. We will also have 6 month warranty. Any questions please ask =)
