Right, so now there's a turbo option for us... cue the "can of worms" question...

Whilst I understand the differences between what a Turbo and S/C is - what are the pros/cons for going either way.

Right, I'm now taking cover for the firey debate to follow....

I think:

turbo: more efficient, hence less charge heat related issues and easier to get higher power levels, parts more easily available

super: easier to engineer as a one-off, improved throttle response because there is no feedback in the mechanism used to generate the boost

I think turbo would be best due to the efficency side. I think SC can take around 20% of output to drive the gears.
Not sure on turbo, basically just adds some exhaust backpressure.
You can design your turbo small and get good off throttle response if you want to at the expense of top end or design for midrange, topend etc.
I guess SC wins here with allover power. But for cost of running its got to be turbo.

Im going heads and cam myself. Hoping for around 400rwhp, maybe 500fwhp we will see. Much cheaper, around £3K all up. Plus Im not hammering the driveline as much.
Will report back once its all in and running. Of course Id need to go forced induction after that for more power. Or a larger displacement engine. www.motorsporttech.com/c6_engine02.asp

If you want huge power (talking 650+hp) then turbo's are the way to go as a supercharger (especially the Eaton type) will run out of puff. If you just want to bolt it on, get a lot of power (520+) and forget about it (pretty much ) then go supercharger.

Simplistic response is turbos are cheaper than superchargers, produce more efficient power increase, far more power potential, installation cheaper and easier to maintain if using specialists as more 'turbo knowledge' than superchargers in the tuning industry as more popular.

Charge heat would be higher comapared to a CF blower I think, although a lot depends on boost pressure uesed ( and intercooling of course )
But turbos are definately more efficient at making power, simply because it doesnt sap power to drive them.

I definately wouldnt say a SC system is easy to engineer. I could very easily build a turbo system in my garage. I couldnt easily do the same with a blower without machinery to make pulleys etc, so I would say that makes it harder.

I would agree with all those comments. Only reliability issue with some turbo builds, is manifolds cracking, or any turbo related "hot side" parts cracking or failing due to the extreme heat involved.

But you cant say one is better than the other. Each type will be suited to a different persons goals, as each will heve different characteristics, and cost different amounts to reach those goals.

I'd love to try the Turbo, but I haven't so can't comment. I own four Turbo cars at the moment but the biggest is a V6 (smallest is a triple cylinder Smart) & there's no comparison with a V8 Chevy engine.
What I can say after 3.5 years of owning a S/C car, is that I loved the linear power delivery which felt more like a N/A engine. Not sure you'd get that with Turbo.

The power delivery from a turbo is very addictive, and there isnt much else to beat it.

But as to whether it suits every case ?? Thats down to each person to decide.

I do miss that big rush once the boost picks up, but I know my car is also faster now, that it doesnt have that, and instead I can get traction easier.

Big V8 turbos feel similar to supercharged ones, just more 'urgent'.
