Ported TVS 2.3

Finally got my TVS. I have been thinking about porting my TVS. Roots blowers and TwinScrews have different way of pushing/compressing air. I know whipples dont gain anything from porting them.
Since TVS is a roots blower, do you you guys think it will respond to porting like the the roots eaton?

Do not port the TVS. Only the inlet and opening *might* provide some small gain.

Why exactly do you say this? Not argueing just curious.

Pretty sure Posi and a few others said there's nothing to be gained porting the TVS.

the accufab single blade inlet is pretty big and matches the blower. The only area I see room for improvemnt is the TB and a mathcing inlet. The GT500 FRP TB is supposed to be that improvemnt but we will see. If I pull a low 600 out of my car I dont think much more can be had without out either: E85,race gas,or cams and head job.....

The VMP TVS 2.3 was designed from the ground up for maximum air flow, power and reliability.
No porting is necessary on the blower.
You may want to smooth out the inside of the elbow but that will yeild little to no results.
The more air you put into it the more power you will make.
We have run 4 TBs on my car from the BBK, Accufab, Dragon and currently running the Big GT500 SBTB. Every time we put a bigger TB on my car the power went up.
Headers and a free flowing exhaust definitely helps.
