300whp with Supercharger?

Hey everyone...

I am looking for "down the road" performance mods to do, without going turbo to get my SVT to 300whp.

I really like cars that are turbo, but just don't want to go through all of the hassle with adding new oil lines and other crap to toss a turbo onto my car. A lot easier if the car already has a turbo factory installed.

Now, back to the topic.

My goals are for every day driving with this car...

I am considering lowering the compression to 8.5.1 or slightly there abouts, with beefier cams, built bottom (ofcourse), head work, injector upgrades, computer work and smal other upgrades to allow my car to run whatever boost it takes to hit 300whp.

Now, how possible is it for a supercharger to allow my SVT to run up to 300whp with lowering the compression, increased head work and the other small mods? Would I need to run 20+ psi of boost on the charger? Are there any chargers that allow for 20+psi, or is there a limit with chargers (never worked with them before, so I am unfamiliar with the amount of boost they can run).

Would a charger be ideal for making low-mid-high end torque, or low-mid-high end power? Or would a turbo be more ideal for that?

I know you can't have everything when it comes to performace with the engine, just would like to get as much as I can without going overboard.

I am NOT looking to make my car a 1/4 beast. If I wanted that, I would have gotten a different car from the start. More or less a quick off of the line car +.. a good amount of trq. and a car that can pull and pull. Especially in a street racing type of environment. Something that can stick with a turbo Cobra Stang or a Turbo Supra on the road, if need be (example). Maybe not that close with them.. but something that could be respectable.. maybe a 12.00 - 12.99 1/4 mile IF I was to make it into a 1/4 car.




Or, if tossing in a turbo is the better way to go for me. I don't really want to dump $20k in the car for the V-8 conversion because I think putting a turbo on the car or a charger with proper mods could keep up with the V-8 conversion for a while, until you hit over 140mph.



I am not looking at taking the car past 120 - 140mph, so, if that helps with my question on the SuperCharger... Also, I would hope superchargers will advance a lot within the next 4 years (that is probably when I will put the charger OR turbo on the car).



Thanks,


Rory

Forgot 1 thing... Does a supercharger have LAG like a turbo, if not.. then wouldn't that be a "more ideal" thing to go with for my application IF I can get 300whp out of one.. with about 20+psi? Since the power will always be there when I step on the throttle?


Thanks again!

supercharger has instant boost but the turbo has better boost throughout the whole range...supercharger is more of a low end boost, will give you better lower end no doubt but if u want some top end with low end a turbo is the way to go....to get a 300whp supercharged car you mind as well get a turbo charged car as it will be cheaper (not as much tuning needed) and turbos are just way cooler in my opinion :P

but if you are set on a supercharged car...300whp has been done b4, just search

depends what kind of supercharger you use, a centrifugal supercharger will have lag. it's basically a belt driver turbocharger, so it does have lag. a positive displacement supercharger like and eaton or a twin screw or whipple doesn't have lag.

I dont know if this will help you any, but I was thinking of turbo charging/supercharging my zx2 s/r. Both cars have a ztec engine but they differ slightly with heads and compression. If you want big boost I would suggest going with a screw type supercharger. Then your going to have to figure out how to mount it and what type of intercooler you decide to go with. I would go with a whipple supercharger (very efficient) and a air-water intercooler. You might want to check out this link. It is a zx2 with an eatom m90 supercharger with an air-water intercooler. I would do the same setup if I had a focus, but instead put on the whipple supercharger because of better efficiency and boost.

Hope that helps
Jeff

With the svt's a supercharger would be a better way to go im looking into that myself and im most prolly going to go the supercharger route. In my opinion the supercharger would give u more power over a turbo but i think a supercharger will be a safer power enhancer

When the Powerworks SC system comes out for the SVT in awhile, its numbers will be close to what you are looking for.

Thanks all..

WinnipegZX3.. when that kit comes out for the SVT.. is that with a stock engine setup? Or with upgraded internals & lowered compression? Cuz, if 300whp, or close to it can be squeezed out of a stock setup on an SVT, I would imagine that more would come out of it :) with better internals.

If having better engine internals won't help at all.. then I won't do lower compression and better internals.


Depending on how much everything will cost me in the long run... I may stick a built 2.3 4g63 stroker motor with AWD in the SVT :) Maybe run 20 - 25psi and do 9's or 10's :)

Just kidding.. although that would be cool.





Thanks again all!

I don't think the PowerWorks will be close to 300 whp, maybe at the crank though.

Hmmm...

Maybe I will just have to go ahead with a turbo.

Thanks.
