even top fuel dragsters' superchargers rob power. (the s/c on those cars rob more power than any of our cars make)

Cgeek2k already proved my point, but i will go a little further into detail.
There are several different types of superchargers. Depending on the type you choose they will "rob" different amounts of power. Even different sizes of a choosen type will vary in the amount of power they "rob". But as it was stated already you will have more power with the supercharger than without it.
Common sense shouldn't have to be proven.

[quote name='ROTARYROCKET7' date='May 17 2005, 08:51 PM']wow. for any conversion besides a 20b for $8k, i would rather purchase another rx-7 turbo...or save a few more thousands and get a FD lol.
I guess im just BSing cuase if i had the money i would spend it all on my 7..

You don't need the front clip to convert to turbo. A "good" j-spec engine will run you 1300 TOPS.
Swap the engine in, splice a couple wires (N/A ECU works works great for Tii engines), and be done with her.
BTW if you want to swap in the Tii driveline, it won't be anymore than 500 total. But you can use the N/A tranny, just don't launch.

I like the idea of turbo-ing a 7 better than SC-ing it. The price is about the same to buy used TII stuff as it is to buy a Camden Supercharger. I got an entire TII drivetrain, turbo, TII hood, S4 rims and tires, and TII fuel pump for $420. Not all of that stuff is required for running boost but that is an example of some prices for some used TII stuff. Granted SC can be simpler but it is easier to upgrade and there are more options when you go turbo. N/A's are fine for running boost on as long as you get plenty of fuel and don't run astronomical boost levels.

Dang that is cheep but are the parts easaly accessable?

The higher exhaust backpressure caused by adding a turbo 'robs' power too.
If you put more power to the wheels after adding something, does it really 'rob' power? I'd say it increases power.
Yes but that exhaust gas is just gonna get expelled into the atmosphere anyway. it is turning waste into power. i dont think that is robbing power. an sc on the other hand does rob power in that it takes power AWAY from the engine in order to turn the sc.

You are overcomplicating things. Yes, exhaust backpressure does rob power. If it didn’t, freeing up the exhaust system wouldn’t add power.
The bottom line is that a car with a supercharger OR a turbo will have more power that a car without. They are just two different methods of increasing the efficiency of the engine. Adding either one will increase the power put to the pavement, so why does it matter which one he chooses? The question was about the numbers you can get with a SC, not a turbo vs. sc debate.

cgeek is right if he wants to sc his na i say go for it. Who cares if its a little less efficiant. its his car. its improves his hp. its unique and so far it seems like it would work alright. at least hes spending money on his engine and not for ricer body parts. Make one hell of a sleeper.

And an intercooler wouldnt be necessary... I like the idea. So ud need the SC, somewhere to mount it, drive belts and another pulley on the engine, intake modification to connect it, a bigger fuel pump and bigger injectors... am i missing anything?

"robs" around 3000hp to be exact
