RE: P-51 intake
 

I put the P-51 on my supercharger 03 gt and the gaines were a lot lower than advertised... I think it gave me like 20 at the wheels and that was with a high performance engine. Plus it has trouble fitting under the hood.

RE: P-51 intake
 

you will loose your shock tower support with that intake, if it even fits under your hood but that would be a good reason to get a 3" rais hood.
