[AWeb80]

I was on the rsmracing.com website and saw a 61 mm throttle body for

a 3100 grand prix. here is the link.

I was wondering if anybody has this on their car or heard of anybody

that has it. does it help with performance and what are some specs.

on it. Is it worth getting. Thanks.

I wonder how a 3400sfi T/B compares to a 3100SFI T/B. I know they are interchangeable from a few different years. larger ports means more air flow. then if you hone/port&Pollish the manfiolds you will get yet more gains.
