FWIW and to any scruts reading this, replacing the SB TB with the 3.4 TB would be the easiest way to cheat is one was so inclined. A few years ago I dyno'd the podium winning SB's at a POC- Thunderhill event and was surprised by the variances form 165 to 201 rwhp on a Dynojet. I took the airbox apart on the highest one to check and fortunately it had the correct TB on it. Easy to check once you get to the TB. Just stick your finger thru the open butterfly. If it's smooth all the way thru it's a 3.4 TB as you can definitely feel the lip in the 2.5 TB. I'm surprise it's not checked more often....
