how much HP would I lose by using 1 5/8\" headers as opposed to 1 3/4\"

With T&D's , no cats , and all the normal mods when combined with the ROE charger? I am wondering if it is worth the extra cash for new 1 3/4" long tube headers ? (this is not my motor, but it is SWEET!!)

On the average 15 to 25hp up top. Personally not worth the money. If you are already running some of the better designed headers out there probably less.

Sean has suggested that whatever the gain without the supercharger, that gain will be enhanced when you add the SC. Figure about 20 to 25% more with the SC.
