Larger Throttle Body?
I have a 1990 Vett with an L98 engine that has a Hypertech power chip and a 160 thermostat and a Flowmaster Cat-Back exhaust system. Can I improve my "ET" with a larger throttle body? How large can i go? What can i expect? Thanks

Jim a bigger throttlebody won't help unless you get more air to the motor. If you have a bigger throttlebody it lets more air in but then goes through a stock plenum stock tube runners and stock intake manifold and head ports. The air flow gets restricted after the throttlebody cause everything is stock. You need to open it up after the bigger throttlebody to see a gain.
