i know they make larger throttle bodies and i was thinking about putting one on my ls but im curious as to what i gain from it, obviously the bigger the better right?
If you don’t have supporting mods; ie an upgraded intake manifold, ported head, cam upgrades, header, nice flowing exhaust system, etc, then getting a larger throttlebody is pointless. The reason it is pointless is your intake manifold can only pull in so much air, a bigger throttlebody isn’t going to make a difference.
So… what’s done to your motor already? If just the average i/h/e, then its not totally worth it unless you’re getting a steal of a deal.
How many times do I have to tell you. Post in the CORRECT forum.
