    GT40 intake on stock HO convo

    When I go to replace that rear lower intake seal in a few months, I might be adding a GT40/Explorer upper and lower to add some hp while I'm at it. If I use the stock 60mm mustang TB will it make any more power? Also im thinking of adding some BBK shorties and some 1.7 Roller Rockers for some more power.

    Don't screw around, go with an Explorer or GT40 intake, 1 5/8" headers and 1.7 rockers. I'm going to be using an Explorer with a 65mm TB. The HO intake is OK for stock applications.

      If you're using an Explorer upper, I would also go with the Explorer 65 mm tb. The 60 mm one will fit tho.

        The 60m will work fine. The explorer intake will get you a few Hp. If you still have stock exhaust manifolds and cats you are choking it off big time. Same goes for the rest of the exhaust 2" pipe just isn't enough.

          actually I am running stock mustang manifolds and a stock mustang h-pipe, and Im getting 2.25 inch dual mufflers and tailpipes out the back. I want to upgrade the mustang manifolds with BBK because the BBK have much better flow because of smooth tubes instead of crimpled tubes like on the mustang manifolds.

            Should be good to go then. The biggest restriction is the factory mufflers and tails on the panthers....the stang headers will work fine if everything after that is up to snuff.
