<< actual dyno
results which showed that adding headers with his bored TB gained him
almost no performance increase over the TB alone. The headers didn't
hurt, there was a gain, but only a small one. I think the TB was all
the engine needed for internal limitations like the cam or the head
ports to become the limiting factor on how much air could pass through
the engine. With the bottle-neck not being the exhaust, the headers
helped very little. >>
Keep in mind that this shows that, if the proper modifications were done to
the cam or head ports *before* the installation of the headers, the header
installation would probably have shown much more gain in TQ and HP than the
above scenario. Just goes to show you need all the proper components working
together, and that every part affects every other part.
Doing my part to beat the point into the ground... :)
