Re: turbocharge or supercharge? (trueplayer69)
Twin Turbos would be sweet, they provide more power and torque and fuel economy. However unless you are skilled at fabricating parts and bending tubing then you will have a hefty price tag on your hands. A roots blower will give you more lower end torque and is the easiest to install. There was a post about this a few months back when there was a discussion on which was better a turbo, centrifugal supercharger or roots supercharger.

If you're after effeciency and fuel mileage (why would you have a Vette in the FIRST place?), a 'hair-dryer' (turbocharger) is your ticket. Lots of pipe, lots of heat, and dreaded 'turbo-lag' (watch a Turbo V6 Buick at the strip)...
If you're not, nothing matches the "OhmiGod, get-the-women-and-children-off-the-streets!!!" reaction you'd get from a Roots-style huffer poking thru your hood (think John Force, Don Prudhomme, Kenny Bernstein)...
Turbos are for foreign cars, F1, and Indy-type cars; nothing says 'American Bad-Azz' quite like a blower.

Re: turbocharge or supercharge? (trueplayer69)
Just for ease of installation I would say a Centrifugal supercharger is the best bet. Better yet would be a Whipple screw supercharger. It can be used with a carb or fuel injection. A turbo can be a lot of work, but it is the best system as far as efficiency goes, but it'll be the most expensive.

F1 don't have turbos or superghargers...

Having owned all the various forms of positive feed units in question....
I'd say for effieciency, go with a Whipple (screw type blower). It delivers more low torq, with the least amount of drag. You can easily spin 12-14lbs boost. Turbos have the dreaded 'lag', Roots type have a pulse to the intake charge, plus rob alot of hp to drive them. 671-1471 blowers look cool, but take ALOT of power to run, and ALOT of mods to the car. Eaton blowers work well in the 6-12 lbs range, but again, are not as efficeint as a screw type. Centrifical blowers are basically belt driven turbos. They are easier to install then a roots type, but again, there is a bit of a lag, and they give big gains up high rpm.
For instant torq (=power), roots/screw blowers are the ticket!!
:thumbs:
My experience is:
-Subaru XT turbo (turbo 4cyl)
-Probe GT Turbo (turbo 4cyl)
-GMC Syclone (turbo 6cyl)
-GrandPrix GTP (eaton roots blown 6cyl)
-GMC 1ton dually (whipple screw blown 8cyl)
-2wd pulling truck (1271 roots blown 8cyl)
-alcohol monza body outlaw funny car (1471 roots blown 8cyl)
Ok...so I like to have fun!!

Re: turbocharge or supercharge? (trueplayer69)
Would it be better to turbo or supercharge an 81 vette? Also where would i find a cheap turbo or supercharger
means you can maybe afford NITROUS :smash:

using the word CHEAP,

Just curious, what are your goals? You want to race? What kind of racing? Just knocking around town? For the money, I'd build/buy a better engine unless you have a pile of money sitting around, which based on your question, probably isn't the case.

Re: turbocharge or supercharge? (dath)
I spent about $9000 changing from a nitrous motor to the 8-71 blower motor. It is not cheap but the driveability to so much better. The bottom end torque is amazing.
I do not regret getting the 8-71 blower.

If moneys an issue, then forget about turbos. A supercharger is a great option next in line for power adder and keeping everthing under the hood. If you want something to showoff when cruising nothing speaks louder than a roots blower :smash: .

Re: turbocharge or supercharge? (trueplayer69)
First off, your profile says that you're 15 years old. What is the legal driving age in California?
Secondly, you're in California. The car is not smog exempt. You will have to retain the computer controlled carburetor and other smog equipment to pass inspection. I really don't think that you'll find a supercharger or turbocharger that can be used with stock emissions equipment.
Then again, I may be all wet.

I would save you money and do a complete engine swap. There is no replacment for displacement... or perhaps just a more efficient emgine :thumbs: :auto:
