Will post a link, or type boost cooler into search and one guy has a full write up on it, the kit is 648 and should only take 2hours to install and basically sprays a mist as boost rises to prevent detonation as the load increases so does the mist, you get a 2l tank which you mix 50% methanol and water the guy who did the write up says 2l lasts a full tank, so I'm going this path soon will post my own results later
