Depending on what pump gas you have now and what boost you run, I would say you can safely go from about 18 psi. on 94 octane to 23-24 psi. on alcohol injection.
If you dont go this way you will have to buy alot of cam two to run some high boost. At 4 to $5.00 a gal after a few weeks of racing and you could have bought a kit.
Higher boost on pump gas or high boost on cam2, think about it. i wish i would have.
