Possible Gains By Switching 70mm Accufab TB to a 75mm TB On a Vortech Blown GT?

[SilverStallion]

I am adding a Vortech Aftercooler to my Reinhart V2SQ setup as well as a new chip. I currently have 366rwhp before the headers went on. I am wondering if it would be advantageous for me to add a 75mm TB to my combo when I get the Aftercooler installed when they are going to be doing a new chip anyway.

Would it be worth the time and $$ to switch out my 70mm Accufab unit that I have on there now when I am still using the stock intake and plenum? What type of gains, if any, would I be getting?

Any input would be great.

I did some dyno testing on the 70 vs. 75 a couple months ago on a naturally aspirated car. The gains were evident going to the 75 even on N/A. Here's the report including dyno graphs, A/F numbers and details:

yes you'll see gains on a supercharged car with a 75mm TB. so go for it.

I just read an article (Muscle Mustang or 5.0) on a TB test on a supercharged engine and the 70mm TB made a couple more HP then the 75mm TB. Doesn't really make any sense and I know magazine tests our worthless in the first place, so take it for what it's worth.

my trick flow plenum and 75mm edelbrock TB are on the way , cant wait to put them on since my tune is set to 11.1 to 1 right now , need more air to get it to about 11.5 , Tim said when he tuned it thats what he was shooting for since I told him I was doing the plenum and TB soon .....
