bet you guys havent seen a stang with a f150 intake on iti'll see if i can find pics...
I think if you read my post one more time, you'll find that I never said that adding an aftermarket TB/Plenum would not increase power. I was merely trying to show that guy that in his efforts to port and make the throttle blade open more, he could have used his time and effort more effectively somewhere else.
The reason that an aftermarket TB/Plenum install makes the litte HP increase that it does has to do with the increased advantage of the pressure differential between atmosphere and the lower intake manifold. It has nothing to do with velocity and little to do with flow.
But doesnt that "advantage" of the pressure defferential come from increased flow? And from what I have read the slight rise is designed to slightly increase velocity. Its like the plenum spacer things..but that extra height was designed into the casting on ALL aftermarket plenums.
This mod has absolutely nothing to do with opening the throttle body further. It just moves the gas pedal. I did it several years ago. Good mod.
Forgot that I did it until I stumbled over this retro thread!
It also places undue tension on the factory throttle cable and also places undue tension of the throttle linkage and the blade shaft. With the increased rate of opening the throttle, you will also be slamming the linkage against the stop much harder than normal when you are going through the gears. In my opinion, I wouldn't consider that good. The gas pedal is where it is at for a reason.
So wait, does this pull the pedal UP (towards you?)? As my gas pedal sits about an inch lower than my brake.and don't get me started on the clutch...
Like San said - we did it YEARS ago. No probs.I think your worrying about nothing. Youll break the crappy plastic pedal before anything else. Loads of folks do that.
... This mod borders on ricer mentality in my opinion.
Ford purposely set up the throttle linkage/cable like that. What you guys aren't thinking about is that when your motor is running and you are out on the road and you stand on the loud pedal, the motor will torque over to the passenger side. This places additional tension on the throttle cable. Just because you can stand on the gas pedal when the car is parked without the motor running and the throttle linkage/bell crank doesn't hit the stop, doesn't mean that when you get on it on the street that the blade isn't fully opening. Ford knows this and intelligently engineered the throttle cable to be slightly loose. It's not wise to "falsely" increase" the tension.
The throttle blade is slightly elliptical, not round, it is not made to go perfectly flat. The throttle stop on the factory throttle body stops the blade right around 87°. The throttle stop on a linkage like the Acccufab is specifically engineered to open the blade precisely 88° as per their technical info in their literature I have. The reason for this is because the throttle blade is not supposed to be perfectly flat. If you look closely, there is a hump over the linkage shaft that runs through the middle of the throttle blade. Keeping the blade 1-3° from going flat. This optimizes the air flow (aerodynamics) over this “hump.”
Additionally the PCM begins to switch to WOT tables after an 80% throttle angle and significant load, and even if you manage to open the throttle blade slightly more (which is highly unlikely under operating conditions) you will not gain any aerodynamic advantage whatsoever, you will actually lose some aerodynamic advantage over the throttle blade. So with these things in mind, this mod sounds like it may not be productive, and in fact counterproductive.
Yes. Besides, coming up with a way to take up the slack and a designing a bump stop was fun.Is the gas pedal being lower than the brake really that awkward for you guys?
I think you just put an end to this gas pedal mod. Thanks for shedding the light!Ford purposely set up the throttle linkage/cable like that.
