I think everyone here has some good points on both nos and having a supercharger/turbo. One thing i didnt see anyone touch on is that blowers/turbos will dramatically raise the engine crankcase pressure due to increased vaccum and/or ring blowby causing in some cases alot of blown headgaskets. how many of you long time nos users have had that happen? I know a few people that have gone through 3-5 headgaskets on thier blower/turbo cars.......each one of those power adders both have thier good and bad points. I think that if both are setup very well along with all safety devices you can possibly use, then both will be able to be used on an engine well into the 100k range. Depening how crazy you get....

 

to conclude, use 50 shots and be done with it
