supercharger on a carby 200

[Anonymous]

iam currently building up a fairly stock 200 aussie engine, but wish to supercharge it. i do know that supercharging puts A LOT of strain on the engine and its components, but i would like to only run a small amount of boost, to give it some more power, as opposed to puting a 250, or 289 in my falcon. i would just like to know, what types of superchargers ate recommended? i dont wish to use a turbo, because i want the acceleration that a supercharger provides. any feedback would be greatly appreciated.
thanks

1) A properly sized turbo can and will out run a supercharged car all day long. They cause virtually no parasitic draw on an engine unlike a belt driven supercharger.

2) Centrifigal superchargers (Paxtons and Prochargers) don't build good boost until the upper rpm ranges and are a perfect example to point #1.

3) Roots type/Screw type, positive displacement superchargers (Whipple/Sprintex, and Eatons) make great boost from the lower rpm ranges, and would be a better option for you IMO. They are more difficult to plumb, but can be mounted in virtually any position. These typically sit directly over the intake on a V8 engine.

What does your budget look like?

I properly sized turbo will have almost no noticable lag. Lag comes in because many aftermarket kits, in order to get more HP to sell the parts, and because most people don't understand how to read turbo maps and figure out what they REALLY need end up getting one too big, thus too much lag.

My volvo's 2.3L is boosted to 15psi stock. You hardly feel any lag at all when you step on it.

But I agree with inliner...if what you want is instant, around town power, a positive displacement is the best option. Downside is that they will require a little more interesting fabrication to make fit a 200. a centrifugal will be easier to fit then a roots.

yeah my budget isnt huge as such, but if needs be i can save up and build it slowly. iam not in any great hurry to get a s/c on it. i want to get it all together, and then spend time on it getting it right. as well iam not looking for HUGE amounts of boost. and turbos, are a lot of work (not that a s/c isnt) and require all kinds of gear, intercoolers and such. i think they are getting overrated. s/c is what ive got my heart set on pretty much.

When you really look into turbos, the system set up is quite easy. For low boost (under 6psi) you really don't need an IC. Remember, and IC is not unique to a turbo. If you have a SC running over 6 psi, you really need to consider an IC.

You can use a stock manifold, get an adaptor made, and run straight to your carb if you are under 6 psi.


If a SC is what you got your mind set on...go for it.

Like Slade said - If you size them right, you can actually run upward of 10psi without an IC or race gas.

Also, there's no need to make pulleys, mess with custom belts, or make supercharger mounting brackets if you turbocharge.

what kind of Hp and torque numbers are possible for a setup like mine (200, oz head, 500cfm carb) running thru a t5 tranny?

g'day. john i honestly wouldnt know the exact figures. but a factory 200ci had 120hp. it will be running through a borg warner 40 3 speed out of an xe falcon. the engine isnt worked at all either.
thats the other thing, i dont need 10psi. around the 3-5 range is what i want. and yeah ive got my heart set on a s/c.

Remember, that 120HP factory number was grosss estimated...not the flywheel net HP. Net BHP is around 90HP and RWHP is about 70 in stock condition.
