is 800+ possible for a supercharger (not Turbos) ?
500ish about the highest I've seen.

 

for a supercharger, even 500 hp is pushing it....

 

at 800 hp for a supercharger, the m otor is actualy stressing to around 1000 because of the torque required to turn a supercharger. Its possible, but you'd need heavy cog setup, a lot of boost, heavily built motor w/ upped rev limiter

 

what seems strange to me is why would a SC need a % of power and not a fixed number of power needed to drive the SC?

I mean, your AC doesn't take 5% of your power, it takes around 8-12 hp doesn't it?

If the SC % logic holds up, then by that theory your AC would take up 40hp if you had 800hp and I just don't see how the AC would suddenly require more power to spin it

as you get into higher power with a supercharger, is the supercharger suddenly harder to turn or something?

It doesn't sounds like it holds up to me

I think that % ratio thing is a rough estimate that a SC requires to run on a stock engine at stock boost levels

same thing with the oil and water pumps - would they suddenly require more power to spin them if you have 800hp?

 

Hmm, over my head. Im happy with my 330 whp

 

I beleive the reason why it is a % of the hp , is because as the blower builds boost the preasure build up between the blower and IC makes it harder for the motor to turn the blower . Same reason why the belt slips . If you vented the blower to the atmosphere there wouldnt be a % of loss , just a set 5 to 20 hp loss like a AC

 

so then wouldn't the same thing apply to turbos becoming more parasitic as the hp increases if it's about the pressure between the blower and intercooler?

 

Put simply, the more air the SC is flowing, the more HP it will take to turn.

Let's say that the current Vortech unit needs 40hp to support 350whp at 8psi.

Then (also arbitrary number) an upgraded blower moving enough air to support 800whp would need much more power to run... let's say 100hp.

Thus, as your power increases, you will need more air, which means the SC will need to flow more, which means it will take more power to run the SC.

 

Turbo's dont have to turn a blower . The spent gases turn the turbo . There isnt any thing taken away from the motor to spin it ...well very little

 

well i know the vortech kit comes with a certain type of supercharger unit, it can be upgraded to. the system comes with a V-2 SQ SC that is good up to about 600 hp so most v6 will max out at 500 hp with a bigger upgrade like to a V-1 trim you can produce more power with the same psi its the same concept of your turbo with diffent internals for spool. It deals with impeller speed within the supercharger, so up grade your SC unit and yes 800 would deff be able to be done, more HP on about the same amount of boost, but as stated the TQ would be totally diffrent with a SC then Turbo, so you must have a built engine that can handle the tq numbers.

 

Yes and no. Remember TC's run off of exhaust velocity and heat energy which would normally go out the tail pipe... so it is not nearly as parasitic as a SC. However, it does increase back pressure dramatically, which robs some power.

Now, remember that a TC system has a waste gate... it is aptly named because the exhaust gas that goes though it is wasted energy. The more power a TC produces, up to a point, it is simply harnessing more of the power that would normally be lost. One more thing to think about: if the waste gate is closed for longer, it creates more backpressure which does rob some power... thus a TC at 8psi is robbing more power from the engine than the same unit at 16psi.
