ppl with the gm s/c kit which throttle body are you using? anybody have any dyno results from changing tb's? ive had the kit on for about a year now and its time for an upgrade.. i am going to do the TB 1st then a header soon after and try to dyno after each step to see extent of improvements.. so far i have an AEM intake modified for the charger and a 2.25" cat-back system. next winter i will prolly upgrade the fuel system and drop a pulley size but just want an easy bolt on part for now... thanks for the input!

I had the chance to dyno my RSM 62mm TB against my stock one with the supercharger. I got lazy and decided not to do the swap during the dyno session.
As with any forced induction, the more flow, the better. Bigger is best in this case. Go RSM 62mm if you can.

i woulda loved to see the difference....i heard the 62 made a huge diff N/A
i *heard* the opening is 60mm, so i bought a 59mm TB

if you get a bigger throttle body isnt it useless unless the manifold (s/c) inlet is the same diameter? unless the s/c inlet is 62mm i dont think the bigger throttle body would do you any good, unless you like bore out the s/c inlet. anyone correct me if im wrong.
viper where did you get it? rsm?
i was debating what size to get and was hoping ppl had dyno graphs to see how/ if it changed the power curve...
anyone got dyno sheets after just so i can check the curve?

mine measured out to 62mm
well then someone lied to me lol......anyways, i got my 59 from a local who was selling it, not sure on where he bought it from (although probably rsm).

62mm t/b bolts right up to the GM s/c. I had it for years NA and now have it with the s/c and love it.
