·Well, last friday, white lightening (95TT) was strapped down for her virgin
dyno experience. all in all it was a good one, i have no complaints.
I've been meaning to get to a dyno in awhile, just to see if my pathetic
trapspeeds and et's at the track could be attributed to the car but for the
most part I found that the low traps could be blamed on only one factor...
my piss poor driving.
My car is straight bpu, so there isn't much to
tune. All the runs were done with the ecu fuse pulled between runs and with
about 2 gallons of race gas in the tank mixed with some pump gas, yielding
about a 96-97 octane rating.
Run #1
Uncorrected: 396.4hp & 414.0tq
ttc, street setting, 19psi
Run #2 **BEST RUN**
Uncorrected: 400.1hp & 424.6tq
Corrected: 383.6hp & 407.1tq
ttc, track setting, tried for 21psi but only managed about 19.5psi
Run #3
Uncorrected: 398.2hp & 420.5tq
sequential, track setting, tried for 21psi but only got 18psi
The corrected numbers were corrected to SAE parameters so you guys could
compare them. The uncorrected numbers are "just for show", since they look
a little better.
All the runs looked pretty good and were pretty consistent and
reproduceable. my only problem was that i couldn't hold boost at all. the
boost would peak to 19.5psi but would fall to about 17psi by redline and it
would fall fast. as you can see by the dynocharts the power peaks at
4500rpm and falls to about 340hp by 6000rpm. Is there anything I can do to
flatten out my power curve? my tq curve looks ok but my power curve seems
pretty pathetic especially at the top end.
The two most relevant dynosheets are at http://www.geocities.com/bigles_va/dynocharts.html
All in all a good day, now if i could just find the reason for the loss of
power as i approach redline i'll be really happy!
