I have a cure all for all you people that really want to go with N20. If you spend a little extra money (approximately $600) and get a J&S safeguard, you will be safe with using N20. I believe you will even be safe with running a higher shot than 50. That is the problem with people that use N20. They usually never get any kind of timing control or fuel enrichment. Then they wonder why their motor broke a rod or a hole is now in the piston. Compression is just as high with N20 as it is with a turbo, so it only makes sense to get some kind of timing control.All the J&S Safeguard is is a knock controler. When it senses the your motor starting to ping, it retards the timing per cylinder. This is probably the cheapest ignition timing controler there is and it is probably one of the best. It lets you use your full advance timing and only retards it when needed. I've read up on it a lot in the past few days and it is a really good setup. I've decided to get this for my turbo setup.
