Whipple 3.375" ?

[Bkingnorth]

Has anyone run with a 3.375" pulley? I'm running 10.30s with a 3.625" and I have a 3.375 I'd like to try. Just curious if anyone has a ET comparison between pulleys.

I run pump gas with the 3.625.. I have a tune with race gas for the 3.375. Racing season is over here in wny unfortunately so I'm resorting to desktop racing until April.
