Gt500 Throttle Body Upgrade

[mustangmike6996]

what are your thoughts on this upgrade? the throttle body is like 130 bucks and the adapter plate is about 90.

there isnt a ton written about exactly WHY the adapter plate is needed. the only thing i can find is that the adapter plate "perfectly centers" the TB in the TB bores of the intake... im thinking about just buying a new GT500 TB and trying to bolt it onto the car...

has anyone done this?

Throttle bodies really don't show any improvement.

Not unless you got a blower attached to it.

ive got mutha thumpr cams, full exhaust, jlt and tune. i think a TB would have more benefit with the cams than a stock application.

I have gt-500 and plate on my car and it fir perfectly and before the tune it made a difference in higher RPM's

what is the purpose of the plate? will the TB bolt up without the plate installed? the only thing i can find about the plate is that it centers the TB on the intake.

No it will not, the plate is required because the bores of the stock intake manifold are for 55mm throttle plates, the 60's from the GT500 unit will not open fully without an spacer plate.

I designed my own adapter plate. Its made out of aluminum but is only 3/16 inch thick, not 1/2 inch thick like the BBK adapter. My car has a decorator cover over the manifold and if you use the 1/2 inch plate you have to toss the cover which is $90 in value, I wanted to keep that cover so I did my own measuring and found I could make an adapter plate that would allow the butterflies of the throttle body to open fully and keep my manifold cover as well. I have had mine on my car now for over a year without any issues. I also will say the GT500 throttle body is the best way to go, its a plug and play, it works with the current computer on board, and there is no adjustments to be made, except to have a new tune for the new throttle body. I read somewhere someone said that you do not get any gains from a throttle body, well that might be true when your engine is in the stock tune, but you get a race tune and that throttle body lets the gorilla out...not to mention with a CAI combination it really wakes the engine up...
