Been driving the car daily now with temps in Florida reaching well over 90 and no issues at all with cooling or reliability. The power is great and raced a worthy opponent yesterday, 2009~2010 Carrera S.. Although I was not able to pass him I was glued to his rear bumper from 20~100mph
which was impressive.
The car is a mid-range monster with the 915 tranny and I foresee a 930 tranz withing 2 years and before any huge power adders.
I am guessing my HP is around 375~390Hp but still could benefit +40Hp from removing the 2 side mufflers and a Dyno tune.
