much. in short, as soon as I whack the throttle open the MAP goes to 100.1
KPA. when it gets to about 3700 to 3800 it begins to drop. @ 5950 it
is down to 95.6. this is the worst that it got in the 11 runs that I
recorded. most times it dropped down to low 98's high 97's.

<DIV><FONT color=#0000ff face=Arial size=2><SPAN class=780360406-02052001>I have
what I think is a pretty good exhaust (1-7/8" primaries, 3-1/2" collectors,
2-1/2 duals with cross over). the intake tract is a firebird
unit. It has 4" plastic tube where the MAF was in the Firebird. it
goes right to the filter housing that I cut the heck out of to make my ram
air setup. I bet that this flows great. I have modified the
front end of my car so that the great big hole that is the grill funnels the air
to the ram air setup. by going into the grill the path of least
resistance is bound to be the air filter holder. The heads are
ported darts (I am working on finding the numbers, but they are MUCH better than
they were when they came out of the box). </SPAN></FONT></DIV>

class=780360406-02052001>I am not really concerned, I just thought it
interesting & I had not noticed it before. kind of makes me
wonder if this is any indication of why my trap speeds are so low
(106-107). kind of makes me think that this has to do with choice of
cam. don't know, maybe it is time for the big squeeze.</SPAN></FONT></DIV>
