I dyno'ed my car yesterday. I was very dissappionted. My all time best with just a cone intake and 3rd gen 5-speed is 135whp, 168wtq. I dynoed yesterday at about 111whp, and 144wtq. First two things that came to mind. Heat soak on the dyno. I had just driven 25miles, and hopped right on the dyno. My car does heat soak quite a bit. I usually give the car about 30 minutes to an hour to cool because my CAI piping will absorb that heat when the motor is shut off. The second thing is my timing is still off. The bad part is the timing marks on my UDP are all wrong. So I can't time the car properly with a light....usually have to do it by sound...which I don't really do very well. The difference between my car when I first dyno'ed and now is I now have a CAI, 2.5" catback, and a UDP. I shouldn't be loosing power. Any other ideas?

I have an idea but you wont' like it. What you do is either get a dial back timing light or put the stock pulley back on, set the timing then install the UDP.

 

Yeah, that won't be too bad, but it looks like I'll have to do that.
