Supercharging a 5.0 witha compression of 10.5

crazy_mustang · Sep 28, 2005

would it be possible having a supercharger + NOS in an engine that has a compression ratio of 10.5 : 1 ?? and if yes what maximum PSI can go for with 100 HP NOS ? knowing that i have a comp cam lift in both intake and exhaust .515'' and rpm range of 1500 up to 5500 RPM ?and a holley systemax intake manifold and a BBK throttle body of 75mm size ? man this engine is owesome lo0olz

Not unless you really don't like the motor

People generally either go high compression (what you have) or lower compression (8.0:1, 8.5:1, etc) + boost. With that much compression, I don't think you really can run any boost, but I'm no expert.

its called nitrous NOT NOS. And you could run boost but not more than 5lbs and even then its iffy with that much compression.

... and if it's a stock block, it would be allot less expensive just to run a cutting torch down the middle of the lifter valley and main journals.

You could probably rent the torch for $25 for the whole day vs. $2500 for a blower then another $600 for a nitrous kit to do the same thing.

NOS, NOS, NOS, NOS, NOS, NOS, NOS, NOS, NOS, NOS, NOS, NOS

NOS is a brand. NOS is Nitrous Oxide Systems, owned by Holley.

10 years ago if someone said they were runnning NOS, everyone knew that they were running nitrous. Now after the The Fast and The Retarded and 2 Fast and 2 Retarded, everyone is so inexplicably jumpy and punchy about someone reffereing to nitrous as NOS, which is still a valid way to reffer to nitrous in my book.
