procharger vs supercharger

[maxpower5]

since both cost roughly the same, but hp numbers are in favor of the procharger, why go with the supercharger. im new to fi and am curious. i looked to see if there was a thread that already compared and didnt see one. so, what are peoples thoughts...

[danhr]

a procharger is a supercharger?

[SC2150]

A procharger is a supercharger. So is a Paxton, and a vortech. and a maggie, and a Whipple, and a KB, and a Edelbrock.......the last 3 are top mount, and the first 3 are front mount. A turbo vs a supercharger will be different.

dont you mean the last 4 are top mount and the first 2 are front mount?

You can be more technical and say the procharger, paxton, and vortech are centrifugal superchargers. The magnacharger is a roots supercharger and the whipple and kenne belle or screw type superchargers

[seanm@stillen]

Prochargers, Vortech and Paxton are centrifugal type superchargers.

Magunson , Whipple, and Kenne Bell are positive displacement type superchargers.

The quick differences between them are that positive displacement will make more low end power, while the centrifugal make more power higher in the rev range.

Each type has its positives and negatives, and it depends on what your horsepower goals, and how you drive the car to better get an idea of which you may prefer.

Good info!

I can give you a lot more info, as forced induction is one of my specialties. Everyone has their own preferences, and like I said, there are positives and negatives.

This year I have worked on some road race cars with a Vortech blower, the power is very linear, and it makes the engine seem like a larger displacement N/A engine. The higher you rev the engine, the more power and boost it makes.

There was a great article in .... Muscle Mustangs and Fast Fords by Richard Holdener. http://www.musclemustangfastfords.co...ion/index.html

It compared several different forced induction setups on a 4.6 liter engine. Great info, great comparison. Sure its not a GM engine but the results all speak for themselves.

i guess what i was getting at was, is the procharger better b/c it cools the air prior to the throttle body vs a supercharger which does not? is acceleration, throttle response, 1/4 mile time better with the procharger sys. it claims to offer 175 hp at the crank, vs less hp for the rest at the crank - or at least what i know.

[old motorhead]

It's all about power delivery. Do you want your extra power at 2500 rpm or 5000 rpm? It's that simple. If you have 9psi of boost, do you want it all in at 2500 rpm of do you want to wait until 5000rpm to see it? Yes, the centri can get you a little more hp per pound of boost, but you won't see it until the upper RPM ranges. The centri's shine at the track.....p/d blowers shine just about everywhere else.

You owe it to yourself to take a ride in both.

Procharger is not the only charge cooled supercharger. The Vortech, the Magnuson, the Edlebrock all have charge coolers.

When you compress air with a supercharger, it gets hot. The hotter the air coming into the engine, the more likely it is to self ignite, or ping/ knock/detonate/pre ignition. Supercharger kits use charge coolers to lower the intake temps to a manageable level.

At a certain point, you need to raise octane to prevent the pre-ignition.

Horsepower is related to boost. Boost is related to heat . Heat is related to octane. To raise horsepower, you raise boost, and in turn raise heat.

Every setup has its advantages and disadvantages, the best bet is to ride/drive each and see what you like. Everyone has their own preference.

I would say it all depends on what you want to do with the car. Since the procharger won't give you the same low end TQ that the top mount blowers will give you, the traction may be better in the 1/4 mile starting off ... for a 1/4 type car you may want to look at these type of blowers or a turbo (with the same characteristics)

On the street, I think the top mount is a bit funner as there is more usable street type power (lower in the RPM range)

That's why I went with the Vortech ... I didn't want 400-500whtq at 2500 RPM's.. I like a linear curve that goes up with RPM's .. not a flat line.

thanks for all the info - i definitely understand this better now vs about 3 days ago. still not sure what i want, but at least now i will make an informed choice. thanks!
