I am surprised that there is so little information about porting positive displacement blowers.
So far I have spoken to Hendrix engineering and done a web search.

Hendix says he is caught up in his own project to port my tvs 2300. Forum consensus says that the gains dont justify the cost.

I want to read testimonials from anyone who has had it done and what their set up is. The only company I have found who offers this is Stiegemeier? Anybody use them before?

They were popular with 03/04 Cobra and 2nd Gen Lightning owners, but haven't heard much about them outside that realm.

He is pretty local to me, also been to his shop, he does great work and is very well know like said in the ford world.

Pay for spray instead. Much better punch for the buck than having the blower or ported or even meth injection on a psi switch. And a pulley swap. Unless already have that in place.

From what I can tell steg has a pretty poor rep over on the Lightning sites. Look up a guy named JokerzL over on Lightning Rodder. Pick his brain on the porting. He's pretty sharp. My opinion as to why people aren't porting the TVS's is because they are so much more efficient and make much more power out of the box than the MP112. The porting on those is sorta like a last effort to get whatever we can out of them as opposed to having to upgrade to a whole new unit. They aren't that great of a blower to begin with but we try to work with what we got.

Thanks all for the input.

You have all brought up some points. Mostly about the effieciency of the TVS line-up. They are efficient up to a point.
IF I AM NOT MISTAKEN; peak power for boost on the 1900 is around 7-8psi then the gains diminish after that, its a little higher for the 2300.

I plan to spin mine at 20,000+ rpms and run a 102tb. The people who have ported their tvs's although few have not pullied their blowers to spin at the speed I am striving for therefore maybe to them the gains dont justify work and money because porting it in those set ups really wasnt necessary. But I know that I may run into issues with my throttlebody being forced shut, so maybe the solution to that lies in porting the upper manifold. And who knows maybe at 15-20psi a good porting may net good HP gains....

What is your HP goal? What does the rest of the engine combo look like?
