Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Terry Q again. The "restriction"

If you would be so kind as to give me another opinion. Take a look at my mods below (in sig). Assume I were to 1) remove precats to complete the opening up of the exhaust, 2) FINISH up my mods with a dyno session that tuned my A/F ratio to optimum with chip, Apexi-AFC, etc.

Where do you think the intake flow restiction would be..? Nice easy multiple choice Q.

A) 60 mm throttle body
B) Extrude Honed upper intake (32mm secondaries)
C) 34mm butterflies in lower intake
D) intake ports in heads/valves
E) More than one
F) None of the above - eveything is perfect!
G) None of the above - hopeless case!
H) None of the above - what are you talking about!

A, B, and C are relatively fixable. Probably would not do head porting or big valves at present. Alot of people have chimed in on this but I want to know what you had to say.. Thanks once again
