I havent data logged yet, i cant get the port to work. but by eye i was getting 12.3 at redline, yes i was building boost all the way to red line. the belt wasnt slipping at first... it is now that i cracked my aluminum crank pulley and put back on the stocker and the shotty reinstall by the dealership.

And your still on the stock bottom end? I am taking easy on mine trying not to push too much past 9.2-9.6 PSI on my motor until I get it built up a bit... I do not trust the pistons / rods to much past 10 psi... The only time my belt slipped was when it was raining like cats and dogs out. At first I did not know wtf was going on and then figured it out.... When that belt slips it is a funny feeling!

Yes its still stock bottom end, no nitrous, no cams... I was getting over 10psi when i had the 3.12 pulley before... so far so good, except when the crank pulley cracked, which broke the joint, and blew the seal which caused me to spew out oil. But thats my fault i shouldn't of barried the needle on the highway. I just hope that the Crank wasnt damaged but so far she seems to be running flawlessly

What brand crank pulley were you using? i was thinking of switching over to a harmonic dampener at somepoint. well maybe you would know any thing i should keep an eye out for that would indicate that the crank would be damaged?

I am not sure what brand it was, got it on a group buy (yeah, I know... stupid)... Here are the pics of where it got chewed up... The key got chewed and it ate in the crank which had to get replaced... I would not use another pulley other than OEM again unless maybe a Fluidampr...

that sounds more like a slipping tranny...
I have talked to a lot of ppl about belt slipping and they say it squeals on start up (which I experienced) or if u lose boost near redline (ie, boost use to climb to 9 up to redline but now goes down to 7 to redline).

Hmmm, Don't think it is the tranny since the rain would not effect the tranny this way. The tranny would also be slipping on a consistant basis I would think.... This was an isolated incident just in the rain on one occasion. I have gotten on her hard since then with no slippage whatsoever.
