Testing
continues on the new ATP bolt-on upgrade utilizing
the first level turbo (Garrett GT3071R) option.
Still sporting the stock TMIC and stock exhaust,
project STI appears even more mild mannered
than the average STI off the street. Once at
the dragstrip, the project car unleashes the
beast within and one can only take note of its
willingness to pull through the 1/4 mile with
so much force.
We
found the 3071R powered STI with the 400/400
combo to be incredibly easy to drive with
most of the torque available even at part
throttle. The turbo seems to compliment the
shorter gearing of the STI gearbox quite well,
providing the most available torque between
gear changes...and even with the modest amount
of power made, the STI still goes through
the traps at halfway through 5th gear...that's
a lot of shifting!
Best ET on CA 91 octane
pump gas: 12.6 @ 109 MPH
With Roger Williams behind
the wheel and a mix of 104 Octane along with
an add'l 6 degrees of advance: 12.06 @ 115.7MPH
Roger finds it easy to nail
consistent low 1.6x sixty foot times with
4500 rpm launches and pedaling through the
spinning stock tires.
More to come...
