Now, I generally want to avoid just using a shot of nitrous. With that said...

Which would be the more ideal setup for power, ease of installation/setup/yattayatta, and cost? (This is assuming a 383TPI.)

1. Twin turbos

2. Supercharger and headers


I know twin turbos can produce a lot of power, but they are an exhaust restriction, albeit not much of one. I also know that a supercharger robs a lot of power, since it's run off the crank, and as such it also puts more of a strain on engine internals. But would a supercharger+headers make more power than twin turbos?

Also, with the exhaust on a turbo, I've seen several different ways of doing it. I've seen one that basically looks like the stock exhaust, only it runs into a turbo instead.. And I've also seen one that looks like upside down blockhuggers. Is there really an advantage to using something that looks like headers on a turbo setup since they're all going to be routed into the turbo?

I think generally Twin Turbo can make more power than superchargers can. The setup is trickier and more expensive also.

 

This is really a difficult question to answer. Why did you even ask it?

You can go beyond the extent you are after with either. There are guys with blowers, turbos, nitrous all running 6's. Its all about what you prefer doing. You can get what YOU want out of either.

A supercharger would be easier since its in kit form.

Generally speaking -- there's more power potential with turbos. But then again, you could build a supercharged engine, that would take all but the most maxed out turbo setups. It really all depends what your after. However, when it comes down to it, the supercharger is run solely off of the engine which robs horsepower -- whereas the turbos are run off of both exhaust gas velocity (which does cause some backpressure) AND also heat which is essentially free. So turbos do have the potential for making more power. When it comes to actually installing twin turbochargers vs. a supercharger -- supercharges definitely have a big advantage for the ease of it. However, not necessarily cost. The cost of a twin turbo setup vs. a supercharge depends on your ability to fabricate. If you are paying someone to do the fabrication -- that's what racks up the cost associated with a twin turbo setup. However, if you do most of the fabrication yourself -- you can really keep the cost down. The only thing that you can do is research the subject and ask yourself what you want to get out of the setup.

turbos are much cheaper if you do it yourself.. otherwise the kit is about the same price as a sc'er kit. they make a much broader power band than super chargers. what i hate about superchargers is that they only make full boost at or near redline, where as at 3k rpms or so they're only making like 3 or 5 psi. turbos are spinning at full boost by around 2k rpms and making much more power(like twice as much) bythe time superchargers just get going. check out my post at the bottom of this page, its called 'interesting article' or something.
