That would probably be me.... Thanx Gman for the support....

 

How much boost you making with the 2.87 ? DOes it build all the way to redline ? or does your belt slip ?

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.

 

Looks to be about like my set up, great #s, If I don't keep up on the tension of the serp it slips, boost dives off around 9psi.
What FMU are you using? SS

I would really like to believe dyno numbers but when I last dyno'd I was at 375 rwhp. The car was much, much faster than stock but 375 at the wheels is huge. The car didn't feel as fast as a car with that much juice. I mean the c5 vette only has like 310 rwhp and it fealt as fast as my 375rwhp. I am hoping my new numbers make the car way faster. One thing I know is that it's pushing 10psi. I will know more when I get the car. I have never posted pics before any directions. I would love to post pics of car and dyno sheete.

 

Thanx!! Yes Im still using the SS box

 

sorry didn't mean it like that. I meant with all the bad threads going around about aam no one really cares for aam....not your car.

 

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!

 

How does it feel like when the belt slips Triji. As I would like to know, so I can look for it when mine slips. Thanks in advance.

 

It's cool, i figured thats what u meant.

 

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

 

It almost felt like my foot was going down on the gas, the revs were climbing and the car was coasting until it caught again.... As if you were driving at a good pace, start giving it gas and slipping into nuetral at the same time...

Thats how I would describe it...

 

Yeah, I had a lightweight pulley go out on me and it did mess up my crank... I should have taken care of the frickn rods and pistons at that time and built a little bit...

 

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.

 

I believe the pulley Triji had on his car is the CNR pulley. Their was a group buy on that pulley a while back. Lucky I didn't install it on my car.

 

Holy crap! I used to have that same pulley, i took it off when i put my vortech on, now im glad i did so!
