Stock 302 + supercharger = ?

[Archangel]

Well, the problem is that I do not have the time or the knowledge to do heads-n-cam swaps and other extensive mods of that sort. So I'm looking for some "bolt-on power" type of equipment, and the best I could come with is a supercharger - they seem simple enough to install, the hardest part will probably be tapping the engine pan to run the oil lines... The way I see it I'll need the supercharger inself, the mounting brackets and the tubing that go with it, a Mark VII upper intake and TB cables, a new belt, and possibly 19lbs injectors. Boost will not be very high as the rest of my engine is gonna remain stock. What do you guys think of that, is it gonna work at all, or I'll just blow something up?

[Roach III]

You can get a self oiling supercharger. I'd go with a Vortech S-trim with 5-8 psi of boost.

You almost have to have a mass air setup. And I would go with larger injectors. Possibly 30 or 36 lbs. From what I understand, it's better to be rich than lean. You could get a tune at the local dyno, but a mass air setup is hard to beat.

[Archangel]

Yeah, I just found that I can run an external tank, or just get a SilentDrive Vortech and avoid it at all. Mass Air however involves repinning the ECM harness, a task I'm not willing to take on as this is my daily driver so I cannon afford the mistakes I'll probably make (I'm more mechanically than electrically inclined).

[Roach III]

You could get a D9S computer and have the whole system tuned. Dunno how much it is for professional tuning, but I'm sure it's not cheap.

If you are running a lopo crank and pistons, I would not recomnd a supercharger. You will need forged internals to reliably and safely run boost. All 93 and back HO 5.0Ls have forged internals.

i believe that it is the 87-93s.

I think you are right, I do remember something about the 86 not being forged.

Actually the 210 HP 5.0 HO engine in 1985 got forged pistons, and that was the first year for the roller lifter cam, roller block, and the stainless steel tubular exhaust maniford, even though they used a 'fake' dual exhaust system.

In 1987 they started using the E7TE heads with 9.0:1 compression, heavier duty block, and also used the good TRW forged pistons with valve reliefs. The throttle body was also increased from 58mm to 60mm.

The TRW forged pistons were using until 1993 when they were replaced with the 'hypercrapic' (hypereutectic) pistons.

How much hp do you want from your car? The stock numbers are 130rwhp/230 rwtq. You can get an extra 100 hp from a nitrous kit or supercharger, but you can also get an extra 50-60 rwhp from the HO conversion. Send your car out to a shop to get any work done that you can't do.
I haven't received my Transgo shift kit in the mail yet. When it does come in, I'm sending my car to the shop. I can't do any tranny work on my back in the driveway on a 30-degree day. Pay the labor and pick the car up the next day.

[Archangel]

How much HP - no particular number, as good as it can get without damaging something. Sending the car to a shop is not an option as I can think of at least three better ways of spending the money I'd pay the mechanic. Plus that, around here auto shops seem to be awfully greedy, according to several of them a simple replacement of a muffler and tailpipe of a friend's Mazda MX3 will cost about $200 - kiss my shiny white ass, you illegal Mexican fucks, I can get all the work done myself in about an hour and I bet the end result will be better too. So yeah, it's gonna be either a supercharger, or nothing, and if my engine cannot safely handle any extra boost as is, then I guess I'll be getting some new front springs, rear gears, and a tow hitch :evil:

It's almost pointless to put a supercharger on a stock, lopo 5.0 because the heads, upper intake and cam don't flow much air and a supercharger would be sort of pointless if the engine can't flow enough air to make use of teh boost.

Setting up a good supercharger is pretty expensive, and you would get a better horsepower return for you money if you started out with a better flowing engine combination.

If you don't have the time to do it right, don't do it at all. If heads-cam swaps are extensive to you, then you should find someone who is knowledgable near you to teach you how to work on cars before you worry about a power adder.
Can you afford to just pay someone else to do it?

[Blaze86Vic]

I kinda feel the same way. If a more basic heads and intake swap are not in your arena, then I think you should steer clear of the supercharger as well. They are not cheap at all. You can have 2 HO conversions for the price of one supercharger, and tuning is a definite must with a supercharger, espesialy on a SD engine.

[Mercmarquis]

You can get an extra 100 hp from a nitrous kit or supercharger,

Do not do nitrous on a strickly street car. If you hit the nitrous and let off the throttle do to an emergency you will blow the motor no doubt. You can get saftey switches to prevent it but I wouldnt do the nitrous anyway.
