Everyone,
I went to the local track here (Capital) again Friday and
I wanted to post more results for those of you considering
some of the above performance modifications.
I ran twice and turned 13.38 the first time(best). This
was at 85 deg. F outside temp., launch at about 180deg
oil temp. Launched car at about 2000 rpm, w/GY GSC's,
2.11 sec to 60 foot.
This compares well with 13.29, 13.31 bests I ran at another
MD track, Cecil county. Outside temp was cooler though, maybe
lower 70s.
Only difference in the car between these 2 runs was the installation
of the Tpis airfoil AFTER Cecil County runs.
So, I ran .09 sec slower even with the airfoil installed. The 13.29 and
13.38 times are good comparisions as I had 2.11 sec to 60 feet on both
runs.
I must conclude that the air foil does very little if anything; it's effect
is more than eclipsed by weather changes.
I also conclude (see previous post) that the coolant bypass along with
a new fuel filter provides an excellent combo.
My previous best at Capital raceway was 13.6 s, this before the coolant
bypass (and new fuel filter ) and air foil. So for sure, the bypass/fuel filter and airfoil
are good for .22 sec, at the same track.
I'll offer some 1 data point on the other (52mm TB, vortex rammer, adj. reg,
and flowmaster mufflers):
I met a fellow with a Black '93 like mine at Capitol the same night I did the 13.6 run.
His '93 ran a best 13.8 with drag tires (Nitto); these gave him 1.9-2 sec 60 foot times.
Well, I met him again last Friday. He had extensively changed the car, adding the vortex
rammer, a 52mm BBK TB, adj fuel reg., and flowmaster mufflers (not the cat back system).
To my great surprise, he ran a best 13.58s right before my eyes. This with a the 1.9 s
60 foot time.
So with all that gear, he gained about .22 s. I have to conclude that the 52 mm TB
and adj. fuel reg. did nothing; maybe the rammer subtracted .05? (like my claw did)
and the mufflers .15 s?
