Paxton Polished Driver Side Mount Supercharger Kit for 1965-1968 Mustangs with a 250, 289 or 302 Engine, 1969 Mustangs with a 351W Engine or 1985 Mustangs with a 5.0L Engine.Don't be discouraged from adding forced induction to your Mustang just because it is not fuel injected. Paxton designed this system specifically for engines topped with a carburetor. Depending on your engine build, your Mustang will benefit from a from 30%-75% horsepower increase. The nearly silent Novi-1200 won't alert anyone to the massive power plant under the hood.
Paxton's kit includes a carburetor enclosure that sits on top of the carburetor. The enclosure pressurizes the float bowls and throttle shafts for seamless response and correct air/fuel ratio. Multiple locations for pressure/vacuum connections are included along with front and rear -8 AN fuel inlet ports. Factory stock compression ratio is recommended.
1969 H-Code cars with a 351W and two barrel carburetor will greatly benefit from this kit. Factory compression is 9.5 to 1 (dished top pistons) which works well with forced induction. Boost will be limited on M-Code cars with a 10.7 to 1 compression ratio (flat top pistons).
