First time writer.s-code here is a ? I don't own a mustang but this letter will discuss my friends mustang.He owns a 91 5.0 LX. He has installed 3.55,cold air induction,under drive pulleys short trough shiffter, and also mickey T street slicks. He ran 14.0s all day with this setup. My ? is his is looking to shave a good second off this time. Here is a list of things he plans on doing new headers 1 5/8, H pipe, flowmasters exuast, bigger injectors,larger thb,larger mass air. Now this is the real ? he is also looking into nitrous,supercharger or a holley max system 2. Does any one have addvice on any one of those systems. He is leaning toward the the holley system he is a all throttle no bottle kinda guy. The holley system is a intake heads cam ect. Well I will be the one doing most of the work so any suggestions would be appreciated. This will be a good winter project. Thanks
