he tuned. its in the dotten lines and mine are solid. Very similar power dips
Not really my area of interest, but looking at the 7AGE from a laymans point
of view, what would I expect ? Basically the longer stroke of the 7AFE block can
be expected to deliver more torque, but with some reduction in maximum rpm.
The increase in engine capacity can also be expected to deliver more torque,
and the factory figures for the 7AFE bear this out.
Strapping on a 5-valve head "should" improve the breathing and throttle response.
However, the increase in breathing may not be as expected, since there is now
12% more air trying to get in and out of the combustion chambers.
Looking at your dyno graphs, I would say that is pretty much what I would expect.
A lot more torque below 6000rpm and then falling over maybe even a little sooner
than the 4AGE. My understanding is that the 7AGE is about more torque, and
that is what you have achieved. Also, bear in mind that the Dynapack is reputed
to be the lowest reading dyno out there. If you want a few more horses a rolling
road dyno will give them to you for the price of a run
