Re: T&D roller rockers, Cam, and Heads
We guarantee 60 RWHP gain over stock with our Head/Cam/Roller Rocker Combo. Most Vipers exceed this number by a good margin. NO DRIVABILITY IS SACRAFICED.
I would advise upgrading the engine first, then add the supercharger as you will have to tune everything all over again once the supercharger is added. Not to mention, installing the supercharger TWICE. We have done several sets of heads for S/C customers and all have had tremendous results.
I am a firm believer in a strong foundation to any future mods, this way I never spend dollars twice for the same modification. I suggest an exhaust system to round out your modifications. Your car will seem like its Aronld Schwarenegger trying to breath from a soda straw, once its running with your proposed modifications with no exhaust mods. We guarantee 100+ RWHP with our exhaust system added to the heads/cam package above..BEFORE THE SUPERCHARGER!! and REGARDLESS OF MODEL YEAR!(Gen II)
Thanks again for your questions,
