well today i talked to this dude....why is it that z28 drivers know the least about cars. He told me that with 10 psi (supercharged that is) his 97 z28 would make 600 horsepower. What a joke. These people are retarded. I even explained the theory to him...14.5 psi will double engine output assuming the supercharger is 100% efficient and he still said "i saw it in a magazine" Theses people are ignorant. Tell me what you think.
