supercharging and turbocharging
Re: supercharging and turbocharging yes and no, it depends
yes if you had an *** load of $$$$$$
yes if the engine is strong enough to take all the psi
yes if you have the room
But on a late model f-body it would't be the best idea. it is best to apply the KISS theory( Keep It Simple Stupid)
the combination of both has been generally found in small displacement ie under 3 litres, all out race vehicles, and/or trailer queen/show vehicles.
on small motors the supercharger is there to provide instant boost and there for torque. then a massivly oversized can be brought in to build power on the top. this was common on old works rally cars.

Re: supercharging and turbocharging I agree with these guys. Could you do it? Yeah but like they said, it would cost a crapload of money,would be probably damn near impossible to keep tuned and would probably run like ***.

Re: supercharging and turbocharging I HAVE SEEN SOME <img border="0" alt="[barf]" title="" src="graemlins/gr_barf.gif" /> IMPORTS WITH A ROOTS BLOWER AND A TURBO. IT WAS ON A <img border="0" alt="[barf]" title="" src="graemlins/gr_barf.gif" /> TOYOTA MR2. TURBO MAGIZINE HAD AN ARTICLE ON IT WITH IN THE LAST COUPLE OF MONTHS. THE SYSTEM WAS BAD. THE ROOTS BLOWER SUPPORTED THE LOW RPM POWER. ONCE THE RPMS WERE PAST THE AREA OF LAG FOR THE BIG TURBO, THE TURBO DID ALL THE WORK. THE WHOLE IDEA IS TO BE ABLE TO RUN A BIG TURBO AND NOT HAVE SERIOUS LAG ON THE LOW END. RALLY CARS HAVE USED THIS COMBO SINCE THE 80'S

Re: supercharging and turbocharging The problem with the chargers is they are not as mechanically or thermally efficient as a turbo. So if you use both on a turbo car, the turbo will be dragging the blower along through the upper rpm's. The blower is sapping power from the crank all the time. It would probably be worth considering quad turbo's if you want to shed mega-bucks but I can't see a huge advantage with a turbo and blower. Maybe it's got to be one or the other depending on the owner's requirements. Me, I'm with the turbo's but I have no experience with huge Rootes blowers and Hemi engines or anything else really big and american for that matter
