Still on my stock internals. Running a D1SC w/ 7psi max and a free flowing exhaust (1 7/8 headers and Mufflex 3.5" with cutout in I-pipe). Looking for a cam upgrade...something mild to moderate. Came up with an XE lobe grind:
222/228 .566/.571 114+4
The spreadsheet I found says it'll turn out to be on a 110 ICL with a DCR of 8.08 and -3* of overlap (if I'm reading/calc'ing correctly). So, I'm assuming this should idle nicely and still perform fairly well in the lower-mid range.
Anyone with thoughts on this as a SC cam? My concerns are:
1) Going too big with the numbers may make the car suffer down low since it's a centrifugal supercharger setup.
AND
2) Going too aggressive on the lobes...

LOL I just realized this is basically one of the grinds Speed Inc sells. So, my only question remains to be regarding the "+4" ground into the cam. Do I want the extra DCR it creates on a forced induction setup or should I stick with a straight up 114 LSA at a DCR of 7.81?

Had some belt slip on the dyno when I had it on the rollers a couple years back. Between fixing that and a valve that had kissed a piston from the previous owner, I'd expect it to be in the 500+rwhp range. I think with the addition of a cam and a smaller pulley to bring boost back to 7psi, it should be near 600rwhp.
