Would it make a difference if i ran a 70mm throttle body with my SC (5gen sh)??

 

I had an RC 70mm BBTB on my prelude that I was parting out.
I sent it to a guy in CO who put it on his JRSC'd lude and he tested it for gains.
It didn't do much so he broke my TPS and sent it back.

I felt minimal gains on the butt dyno, and I got it for a good price, but i was NA w/ boltons + cams.

 

This i a pic of my BBK 70mm TB and the JRSC S-Tube for a B18 VTEC.




The inlet of the S-Tube is only 61mm, so i guess there will not be any gain
