what sort of gains should be expected from a 4-2-1 manifold?..
manifold - gains?
-
#1
-
#2better top end
-
#3is it 4-1 for acceleration
-
#4yeah
they will both see results in acceleration -
#5how hard is it to fit a new manifold?
-
#6mine was easy to do
i have a gmc 1 -
#7its actually the other way round, 4-1 is for power ie top end, and 4-2-1 is for torque ie acceleration, hence why the vts employed the 4-2-1 to give it better low down grunt as they arnt great below a certain rpm
