The dry system pumps add'l fuel in through the exisiting fuel injection system.


I looked into nitrous. bad idea overall. it's rather harmful to the engine. raises combustion chamber temps quite a bit. the problem comes in the form of running too lean. lean means really hot. if you have a way to dump more fuel with the nitrous you might be ok (more fuel would help cool things down). or perhaps water injection. the thing is, with this added heat, you will probably run into the problem of scorching pistons and rings and valves. not fun stuff to replace.

I just purchased a NO2 kit for my 95 540i. Its a "dry" system. To be somewhat cautious I plan on only using a 75 hp boost nozzel and having it only kick in over 3000 rpm. It seems logical the engine should be able to handle an extra 75 hp but I don't want to push the limit. Bavarian Autosports recommends no more than 50 hp, but I think it should be able to handle 75 hp. Anyone have experience with Nitrous systems in their 540s? How else can you boost hp by 75 for $550 plus $600 labor?

Also I just bought a new open air intake kit (cone filter instead of enclosed) any feedback on it?

I want to upgrade the exhaust but done want it too loud. Anyone know of a deep, not too loud exhaust set up?

Lastly, was thinking of putting a stabilizer bar to connect the top of the struts -- will it provide any noticable difference?
