[QUOTE="hammerhead2, post: 9303898, member: 75111"] The Thumper Cams require the phasor limiter but can use stock springs. Most dyno test I have seen suggest about 20-25 rwhp with these cams. My buddy had a set in his car with full exhaust and std bolt-on's it made about 340ish to the wheels. He has since steped up to Comps SPR series cams and is making about 360ish. P.S. No they are not available for 03-04 cobras. They create a lot of overlap to get the sound which is not something you want to much of on a supercharged motor. [/QUOTE]
