RE: Boost Bottles?
Unless your going to fit a wet NX kit then there really is no point other then to run extreemly rich one minuite then to have some power the next. The real deal will be to run normal then run really powerful.
Dry kits are only suitable for modern cars with oxygen sensors that can richen the mixture when they detect more O2, which the NX will fool the sensor thinking its detected - unfortunatly our hobby engines don't have oxygen sensors...
