Having the two srt's is a blast but also a pain! Went to track today but first here is my luck. About 50-60 miles ago I put on a 61mm pulley from eurocharged on my Grey srt, I bought it back on black Friday. My SC stopped engaging and I assumed it was IC pump. Had one sent express mail, put it on to find the issue is still there(NW Bosch IC pump). Bleed the coolant and will be double checking the pump this weekend. I believe It is the 61 pulley not sitting correctly to engage the SC, so grey had to stay home.

Blue - Double stacked 64mm and 178mm, with custom manifold, SCAI, supercooler and iso-kit had a best time of 13.3 with mainly 13.4 all day. Could not hook up for $hit best 60 foot was a 2.1 trap time of 107 when I ran the 13.3. Im little down about it but I know it is faster just cant get it down out of the box. No going sideways trying 40-60% gas then slowly putting it down. Last year in blue when I was running a 13.5 I was doing a 2.0-2.1 60 foot than as well. Not sure what to try next here maybe put the mickey thompsons on and see what happen, wish I had the other car to compare it to but will work on that.

Going to put stock pulley back on grey to determine pulley is the issue and than give eurocharged a call.

Always open to opinions and suggestions.
