Re: Porsche 991 GT3 to include GT1 motorsport engine...
JimFlat6:
Notice that the 2.8 has taller stacks for more torque and the Singer has shorter stacks for more revs....
Jim, the Singer's stacks are about as long (or even longer) - it's a bit deceiving, since the throttle butterfly is placed about half way up (in the square shaped coupler) and extends further down to the heads. That 2.8 has the slide-valve injection placed at the very bottom, so it looks like the stack is longer.
