220HP supercharged 1.6 liter?

[Mazda360]

Sorry I wasn't sure exactly where to post this. My friend who goes through cars like a whore decided he is going to buy a '91 Mazda Miata off Craigslist. The car is advertised as being a supercharged 1.6 liter that puts out 220HP on 6 psi of boost, weighs 2100 lbs, will burn rubber at 100 MPH and has $25,000 invested. I'm not very familar with these cars but I can't see a 1.6 liter making 220 HP on only 6 psi on pump gas. What do you think? Wish I had more information for you.

Not true. It'll put about 160ish on 6psi of supercharged boost. Total lie. I've owned a '93 with a GReddy turbo kit that I messed around with. Don't believe the add.

'91 Miata's barely put down 100whp. I highly doubt he's getting 220 crank, much less whp from a 6psi blower. I had a '99 with a Jackson Racing kit putting out about 6psi and I only put down about 165whp w/header and exhaust (115 stock).

superchargers are usually not huge power getters for 4 cylinders. Correct me if i am wrong.

They don't need huge numbers, they usually give the car a GREAT curve. Lots of power in the low rpms.

Very unlikely; 220 from a 'low boost' SC...point your browser to miata.net, and check out the FI section, if you'd like some datapoints. My 1.8 turbo miata, running 9 psi, runs ~ 200-210 HP, depending on the tune.

Just ~ 150-160 hp in a light-weight early Miata makes for big fun, though. And, as others have noted, the flat torque curve of an SC makes for great driving.

tell him to get a NB and do LSx swap!!!

If your friend doesn't take your advice, tell him to have the seller provide a dyno chart at least. If the seller clams up, you're done. And if he coughs up the dyno chart, maybe he's still lying.
