Hey guys. I need some advice about adding a supercharger to my car. I have read and searched a lot and have read a ton of opinions, ect. My engine is fresh rebuild with stock internals, custom ground cams and a crap load of head work. My friend owns a machine shop and has been doing this stuff for 40yrs. All of this work has cost me zero dollars so I haven't pressed him about everything he did. I have a cam spec sheet, but I don't know how to read it. It's the one that shows where cams were checked on the analyser, not the card that comes in a box bought cam. He swears that this engine is between 400-450 flywheel HP, but that sounds high. He knows his stuff and has built many of these over the years. He also says that I can turbo or supercharge it with no problems as long as it's a safe tune. My question is that if I have stock internals in the bottom end, although balanced, ect. How can I supercharge it and use it as a daily driver and still get 100,000 miles out of it. I am old enough now that I can drive a strong car without keeping my foot in it, but I do want it there when I want it. Such as when passing or getting on highway. My desire is for 500 RWHP and from what he says I can do this easily and still only run 6-10psi boost with what he's done with the engine. When I needed the engine rebuilt due to a small crack in the block at the back that really wasnt an issue, but would gather oil and make a dime size spot after a few days, from an accident, I hadn't planned on doing all this so I didn't go with forged internals. Plus he doesn't charge me usually for what he does because we help each other out, but I can't ask him to rebuild an engine that he just worked because I was stupid and broke it, ya know? My neighbor came over last night and was saying I needed a bunch of extra things as the cars sits now and that a KB would destroy my engine pretty fast, even driving like I have some sense. He even said I should put on a Saleen SC instead because the KB is too much. He also said I need a Diablo Predator instead of the SCT tuner. He's had several SN95 Mustangs and says he's the "go to Mustang guy". I've read articles where these magazines have gotten 399HP out of a stock bottom end 4.6L 2 valve with cams and head work and TB, so I guess what he is saying is possible. If I am at that HP without a SC then it seems that adding a SC would put me well over 500 RWHP. I don't quite understand what it is that would actually kill the engine as far as boost vs total HP. I read see that many of you guys say 450-500 is max safe HP on stock internals, but is that at flywheel or RW? Is it the excessive HP the breaks the stock internals or running too much boost? Obviously boost increases HP, but if a NA engine makes 400-450 HP and is considered safe then could I add a SC and run lower boost with a safe tune to make 500 HP? All of the opinions and advice are confusing sometimes. What many of us need is someone who actually knows and can give advice from experience, not what they read or information they got somewhere else. I know I can pretty much install any part I want, but I'd like to avoid causing damage to this fresh engine. I'd like to get 100,000 plus miles out of it. Also, can anyone read this cam spec sheet and tell me what I have? I tried to figure it out, but I don't see how to figure it since I don't see the stock rocker ratio listed.
