Throttle Body issues - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Have a 2010 with a 402LSX using a Magnacharger Supercharger. Due to the fact that the throttle body mounts on the front of the supercharger, I'm forced to use the factory TB that came with the 6.2LS engine. I tried aftermarket TB's and they all flutter and close under full throttle due to the blade being affected by the spinning of the SC rotors and the close placement of such. The OEM TB is the only one that doesn't do that but I feel I'm not getting all I can out of my engine due to the TB opening size. Does anyone make a TB that solves this issue, which I'm finding out is quite common. I await your replies. Thanks

I run a BBK 102mm on mine and have no problems, my tuner did drill a hole through the throttle butterfly though to allow more air through at closed throttle.

Awesome looking engine bay, Stub! Sorry to hijack, but that's nicely done, no extraneous BS.

Should be able to get a 102mm to work. Either Nick Williams or BBK,without drilling a hole.

Depends on power level/boost etc. At higher levels even a stock TB will get stuck shut.

Goto a cable TB if needed.
