Throttle body ? 70 or 75MM ???

[MoonlightGT]

OK...i just bought a trick flow upper intake plenum. now i want a throttle body to go with it. on the trick flow website is has a chart with the CFM ratings of the different components together such as , the stock plenum with a stock TB, then with 70MM , then a 75MM. then they have the trick flow plenum with all 3 TB's and the 70MM has more CFM than the 75MM! does this make sense to anyone? if so tell me why. i need to know wheather to buy a 70MM or 75MM.

heres the link to the chart so u can see what I mean

i've always been told to go with a 70mm...thats what i went with and it was a nice addition...way better response!

I would say 70mm if you don't plan on doing much 75mm if you plan on doing a heavly modded n/a or s/c

I have a 75mm ,but I am Running a S/C

i have a 75MM and plenum..i'd just go with a 75MM cause who knows what you might end up doing in the future

70 mm is definitely the best way to go N/A. If you do a lot of modding or supercharging then go with the 75mm. :thumb:
