Need help picking out a supercharger

[Slow 5.0]

I'm going to start modifying the engine on my 86', starting with a set of AFR 185 heads and a supercharger. I've been doing some research on the superchargers and stuck with which brand to go with. I'm look for something around 5-6 psi, but able to change boost to 8psi if I wanted to. I've been looking into the Vortec, Paxton and Powerdyne and torn between them all. They all seem to have a complete kit.

Does anyone have recommendations to what brand to go with? Any pros and cons?

I always like the look of the Kenne Bell superchargers.

Slow it really depends on what you want to do with the car. Roots blowers (KB, Roush) make power at low rpm in other words they hit fast so your car needs to hook up well or you will just spin. Centrifugal blowers don't make much boost below 3,000 rpm. Powerdyne kit is easy to install in either the 6 or 9 psi kit but it is a bad idea up the boost on them, they overspin and you kill the blower. If you go with that one just get the 9 psi kit. I have the FRRP 9 psi blower on my car which is made by powerdyne. You can see it in my site. Easy install makes good power, cheapest kit but again bad idea to go higher than 9 psi. Vortec, Patxon and Procharger kits all grow nicely if you want to up the boost later on. They are a little harder to install, you have to run and oil line from the blower to the oil pan. They cost more than Powerdyne or FRRP. If you have not converted to mass air you will need to and with h/c/i and blower you will need a dyno tune and chip. Your long range plans for the car will tell you what blower to get. If you want to go to 9 psi don't waste your money on a 5-6 psi kit unless you go KB. My 2cents.

if you need a nice maf meter set up I have one for sale but it is tuned for 24 lb injectors right now

Well as far as my goals with the car go, Its main purpose is between a weekend warrior and a daily driver, mostly street duty. Overall goal is have the car run in the 12's or high 11's. I know most of that besides mods will be up to my drving skills and the lightness of the coupe. I do want to see the track time with the coupe or at least twice or more a year. Now as far as suspension mods and air monitoring mods go. I have just about the same one as you have Kenny brown sub frames,strut tower, and 4 point lower and D&D upper and rear lower control arms. I'm already converted to mass air, which the MAF is still stock 55mm. I was thinking about the roots blowers, but with the traction i have now, I most definately not have the hookup i want. I'm leaning towards the powerdyne, just due to not much hurt on my budget but I really won't go over the 9 psi mark. I have looked into the vortec a-trims which are around the same price but just a little worried about tapping in the oil pan for the engine oil for lubrication for the charger. more or less worried about an oil line failure, etc.

Prochargers don't tap into the oil pan; they're self-contained. They kick in at higher RPMs and make tons of power, so great for the track and won't kill your gas mileage around town or slide you sideways before you even get started. They're not the least expensive s/c around, but labor might cost less due to not having to run lines for oil.

In your first post you said you wanted to do heads and sc are you doing both at the same time or one at a time?

mostly likely both, just to have the add assurance that I'm using proper head gaskets, plus to add better flow than that e7 heads I have on now, which was a definate improvement from the original e6 castings.

Okay here is what I think. Blower, gears, offroad exhaust should pretty much have you in the 12's especially with slicks. Heads are not much good without intake and cam( throttle body also). Once you go h/c/i and blower you now need injectors, maf and a dyno tune to make it work. You will have a wicked fast stang. If once you play with that wicked machine if you ever think you will want more boost to run 10's buy a vortec. All you have to do to the powerdyne is overspin that sucker and they break. If you want a nice streetable inexpensive blower and never try more than 9 psi you will probably like the powerdyne. My budget is small so I went with the biggest bang for the buck and like my powerdyne. My car does not see the track but if it did I would expect 12's.

I always liked the Prochargers.Like he said.They are self contained and dont use engine oil to lubricate.

That's great information niclely laid out Boss.
