mini pull in my truck tonight i still dont under stand why im only seeing 7-8lbs of boost with a 3.4 pulley on my p1 procharger maybe this video will help you guys to help me figure it out. i was seeing 10-11 lbs b4 my cam and 80e swap on a 3.7 pulley cam " 220-224 581-581 115" ... let me know what you think

 

looks good but is that a blower cam? What Brand cam is it?

 

its a comp cam

 

The Belt is Slipping with the 3.4 and it was not slipping with the 3.7

 

but what confuses me is that i had 10-11 lbs running through it b4 the cam swap and wasnt seeing any slip so why only after if thats what it is?

 

There should be fair amount of belt dust around your blower and under the hood.

 

Belt slip is your problem. You could try a Reichard pulley and/or get a heavy duty tensioner from Joe at leftcoast32.

 

cool i have a reichard racing pullet but do you have a link to the tensioner?? thanks

 

runs good!
