Hello Aaron!
Hello Aaron!
Excellent article, but I believe you misspoke here:
"This allows a vehicle to have both low-end power and high-rev power - something that was not possible before VVT. "
As I'm sure you know, power is a measure of horsepower, while torque is a measure of twisting effort.
In the first sentence, you probably meant "low-end torque" and "high-rev power"...or maybe I got it backwards, but it's not power at both :).
My ''87 Alfa Spider, 2.0 also has a primitive form of VVT, but only operates at WOT, when a switch on the throttle activates a solenoid in front of the intake cam which opens and closes an oil passage to change cam timing. Hardly noticeable and not variable. Just on/off.
All the best!
