Who out there has completed the throttle body mod? Did you do the 61mm or the 63mm. Your experience? Throttle response improved? Very noticeable? I am considering this mod , my main concern is improved throttle response and not really hp gains as I believe the gain is small. Thanks for your input and advice.

Well it really depends on what else you have. My intention is to push air and that's what a larger throttle body allows you to do. I have the high-lift Schrick cam in my car, plus 15% pulley and Powerchiip (see sig line) and in that setup, you need to go from 57mm to either 61 or 63 depending on who you get it from. Mine's 61 and I have no issues at all with it. I wish the larger one had been available but it wasn't. Too bad for us early adopters, something else always comes along afterwards.

Anyway, my throttle response is great and I think it would be impaired if I had a stock TB now that I have the cam installed.

Thanks for the input Graham,

By the way I have the following thus far

Thanks again!

 

Another thing you need to look at is that people like Randy Webb decided to go with a different approach to boring out the throttle body...give him a call and discuss,
