Accufab Standard 75mm TB vs. Race 75mm TB

[SLO_5-OH]

Has anyone tried both of these throttle bodies and have dyno numbers and/or track times to verify which makes more power?

Did test a few years back with our NMRA Pure Street car, we found the reg 75mm worked better, the Race version 75mm with a 90mm blade had a little more turbulence and we ran slower and made 5hp less.

I have found it depends on the set-up, with boost it is much less of an issue but in that case I would just buy a 90mm
