Aftermarket thottlebodies
I was wondering if there are any out there that would fit on the stock intake manifold, but would be big enough to make an impact on performance. I did this on my Z28. Moved up from a 48mm (stock) TB to the 58mm. I felt it right away using the but dyno and dropped a tenth in the 8th mile when the car was NA.
