ported tvs supercharger??
in the meantime while you're saving your lunch money. 

Its something you can do in a day, one day while you're bored...break out the dremel or high speed drill and port away.
Put it this way...the TVS stock pulley (3.15) makes ~20psi. A 2.7 makes around 24psi. Plus the unit already outflows the M62 by over 100 CFMs.

No one to date or documented has ported an 1320lsj harrop Tvs supercharger that I know of, I have thought about polishing the inlet side for it does have a course texture to it, gains would be very very minamul if any so its not reall worth it, eaton as stated that the Tvs is best as is from the factory. It's best left alone

Correction HARROP has stated it is at peak efficiency and porting will decrease it's potential. Again, it is a dumb idea to do. Please read the FAQ. Let me search it for you....
