Who would do HCI over a SC??

ttt...I want more input on supercharging / maintenance.

There a web site I think it's superchargerhelp.com or superchargeronlinehelp.com.

If you are REALLY serious about learning forced induction stuff, just lurk around on the various power adder forums and read some of the older threads.

It won't take you too long to start to see the trends of what it is like to have a forced combo.

So just up the n2o to 150, NOS sells a progress controller that allows you to adjust exactly hom much n2o (percent wise) and how fast to introduce the rest. Say you set it for 25% every 1 sec that way it's slowly introduced and not as violent that just 150 all at once. .02

That's about the smartest decision you could make adding it gradually like that. I don't think I would do it any other way. Still, on a stock engine I don't think I would do more than 100 shot but I am conservative.

I have always wondered how come sc or turbos are not real reliable. I mean, the 03 cobra comes with a supercharger and other cars do too. Same for the turbos. What makes them safer than getting are cars tuned for that?

The factory does an enormous amount of engineering & testing, and they are very careful in how they select their parts, and how they assemble them. A lot of thought goes specifically into reliability -- performance is secondary. The factory tune is extremely safe, because they have to assume that some asshat will put 87 octane gas in even though the instructions say premium. They don't go anywhere near the edge (and they can't, without knock sensors they have to be real careful with the tune). When you do it with aftermarket parts, you are usually not putting together an entire package engineered by one company, so you can end up with tolerance stacking, and variable quality in the parts, etc. You are also more susceptible to assembly errors when doing it by hand, especially if you're an amateur. And you may tune it for some safety, but most people put an emphasis on getting every bit of available power.

The 03 Cobra can take a lot of power because the fundamental design of the engine is much stronger than a production late-model 302. No holes for lifters, and four extra bolts on every main do make a difference. Among other things to be sure.

Actually you can go 150 on a stock 5.0 (with proper fuel/spark/timing adjustment of course) anything more than a 150 becomes a concern. And yes the controller make life for the engine much easier.
