[Shotimes] LPM owners

Sun, 23 May 2004 20:13:05 -0400

    The y-pipe came from http://www.performance-plus.com/ and is free flowing,
mandrel bent and comes with the cat's built in. I haven't got around to the
rest of the exhaust yet so I'm assuming it sounds pretty much stock as I
haven't met any other people that own sho's around Dayton. The sound comes
mainly from the cai that I got from shoshop a couple years ago. When the
secondaries open up, it sounds to most like it's coming from the exhaust but
most is coming out of the intake. The sound it makes is a deep growl. I
understood when I got the car that our engines aren't torquers down low but
once you get them rolling they'll hold their own. At the moment I"m trying to
get my car running as good as possible for once that's done I want to put a
zex kit on it. Got to at least try to stay with my little brother in his
syclone. Last time I ran him he come flying by me like I was sitting still,
hahaha. I learned something that day. Our cars aren't the only vehichles with
weak tranny's as he had to park his sy when he finally made it home barely,
and have it rebuilt.

  I also have the 93 ATX, and was wondering about an exhaust upgrade. You up
for a couple of questions?? What is the PP y-pipe (I did not think they sold
an upgraded Y pipe for the ATX- at lest at the SHO shop)? Also, did you just
upgrade the whole exhaust to a flow thru muffler, or did you also upgrade the
cats?? And how about the sound you like so much- how much different then the
original exhaust system?? I have heard some sound complaints using the
flowmaster mufflers/exhaust?? Did the exhaust upgrade gain you any additional
low end torque??

  Thanks

        The car is a 93atx, tranny fully updated last summer and is still
tight.
    I've installed a 80mm maf, d4u1, ss cai (I like the sound), and pp
y-pipe.
    Other mods to the car is eibach/tokiko and 96 front brake upgrade. Guess
    I've always noticed the tail pipes being sooty since I put the lpm on
    originally but when finally getting the car on the dyno it confirmed it
was
    running real rich. On the dyno chart it started out at idle at a 1.3 a/f
    reading and then steadily dropped from about 3600rpm on up. I got the lpm
    back yesterday and took it for a drive and it definately has a whole lot
    more power now as it get's serious torque steer on the 1-2 shift. The 2-3
    shift is where I notice a bog (right word?) just before it shifts into
3rd.
    Without putting it on a dyno again soon I'm hesitant about driving it
much
    for long distances for fear of it running lean and hurting something.
I've
    been doing quite a bit of research on the Tweecer also as of late and it
    seems to be 'the' way to go but not being a rocket scientist I'm not sure
of
    the time it would take to learn the program, although they state you
could
    send them your lpm and they could make a file for the program to start
from.
    That would be another couple weeks back on the stock mode. There's a huge
    difference in the way the car performs with the stock maf on it than with
    the '80 and lpm,
          Any newbies to the tweecer that could give me input on the learning
    curve as I'm seriously considering it for the main reasons of not having
the
    kind of money it'd take to fly TedB here and tune my car and I can see
the
    dyno time adding up.
        Sorry this is so long folks
