as most of you know there is a 99+ (or split ported 94-98 conversions) supercharger adaption kit in the making. we will submit an article in the coming months. the final cost would be lower than any other supercharger kit out there. this is untested and not for sale, but just letting you know there may be some good new kits coming out for 99+ stangs. if you have questions or just want to *talk* you can hit me up on AIM: AtrusMSTNG.
