AdjustED Cam Gear Running your car at the track on weekends?? You installed the Schrick camshaft, as that was the best at the time. And you have been thinking of upgrading your camshaft for more power in the lower rpm range to get you out of the turns and faster to the straights?? Feel the need for a bit more torque on the DD when the track isnt the issue, and yet dont want to loose that strong top end charge of the Schrick?? It is as easy as advancing the Schrick Camshaft !! My AdjustED Cam gear is already Degreed for your camshaft and a bolt on easy part, to gain the torque and HP from the camshaft. No need to spend on a new camshaft... use what you have and Rock!!

Look at the spec on the camshaft.. ICL and LSA numbers... add in the S/C and changing the cam phase, and you have a power gain thru the ENTIRE RPM range. Keep in mind the facts and the statement that if you advance you gain torque -but loose top end, is ALL dependant on the LSA and spec of the camshaft and the induction!! Go back to the first post and look at the dyno of a degreed camshaft.. the slight blip at 7300 revs was do to me running OEM inj and stock Map!! Looking at the dyno you can also see that the MID range was opened up.. a Plus+ Plus to any camshaft.. Just saying..................................... Thumper
What's the best way to contact you? I just found out from my mechanic that my head has to come off, and I think this might be a good time for me to upgrade...
