Is it worth it?
Hey guys. I was thinking of purchasing a new throttle body for my 1999 FRC. I have halltech air induction system. I also have magnaflow SS exhaust with high flow cats and dynomaxx ss headers. So I was wondering if buying a new bigger throttle body will help in performance any or is it a waste of money. Also what is the biggest TB you can run with a stock intake and what brand would u recommend. THANKS

Hi,
I've never actually changed one out. So take my words for what they are worth. The stock throttlebody is good for a substancial amount of horsepower. More than enough for a stock LS1 with bolt ons. Unless you are running FI or heads and cam, there really is no point to installing a larger throttlebody. The larger one may actually slow your car down except at the higher rpm ranges.
Just my opinion.

Waste of money. Better money spent, pick up a used one and send it to Mark Shaner to be ported. You will only pick up a few hp, but the throttle response will be snapier.
