What is the pros and cons about turbo and centrigual supercharging a smallblock, I'm supercharging mine (vortech) but wondering what difference turbo would have been and weather should have gone that way
Fastest street cars in the world use turbo chargers. That should tell you something.
Not quite. Laws of physics essentially says that something can't come from nothing. So the turbo cannot make power from nothing.Also know that a supercharger takes power to make power while a turbo uses no power to make power.
SimplisticallyAs far a lag goes if you do it right, you can reduce lag greatly.
The quickest "race cars" are, and he's not building a race car. Nitro cars use a blower because of the volume of liquid fuel that needs to be physically pushed into the engine, not because it is a better system are makes more boost.They are making 8000HP with only about 45lbs of boost.It's basically more of a liquid pump than an air pump..Your not going to get a turbine to be able to do that sort pumping action.And the quickest cars on the planet are supercharged... So what?

IMO it has to do with regulating boost. I read the NHRA's rule book concerning use of turbos in Pro Mod. It's severe. They are showing signs of loosening up, but don't hold your breath. Rule making bodies aren't known for moving quickly, except when showing someone the way out.It's a moot point because the NHRA rulebook specifically outlaws turbochargers in the Fuel classes, and has for years. There has to be a reason NHRA won't let them run...:blob:

In defense of NHRA (or NASCAR for that matter), they don't want anything that will screw up the show. A track oil down from a grenaded motor or domination of a particular car tends to screw up the show.
There probably is some parasitic loss to the engine, but for the most part it is driven by the heat in the exhaust that is otherwise just wasted. When you figure that about 1/3 of the total energy in the fuel tank is destined to go out the exhaust pipe, the available
Valiant, pick up or download Corky Bells 'maximum boost'. It will give you a great insight on why to go turbo over other conventional methods, and may even answer some questions you may have about turbocharging. It is the beginners handbook to all things turbo. I can't tell you the number of people who are dumbfounded seeing a turbo on one of these old Mopars, many are still stuck somewhere between the lines in a vintage Direct Connection engine manual; still attempting to get the 'quench effect' and ordering porting templates for their 906 heads..
