i had nitrous and no meth so i used that it gave a really good response.the thing would rev to redline as fast i could find the next gear.lots of fun on only a 50 wet kit fron nx.now for the bad news i am getting pressure in radiotor just a little(can see around cap)im thinking head gasket from block distorting under such a great amout of cylender pressure but if you have a aftermarket block would not be a problem.so i would say it depends on your hp you already have if your close to 450 i would not use nitrouse due to load it puts and block tendency to split around 500 hp.but they or cheap in my openion.im putting a set of gaskets might play with cam timing and put her back for some abuse of that cocktail nitrousand boost im hooked
