Topgunz - air to air upgrade

cupcakez

Emailed Seb. regarding a possible tune and about the pullley swap topic -- whether or not he thinks its worth it or not.

Doesnt the 928 place offer an option in which they send you the ceramic bearing parts / impeller and you can have a professional install it into the blower as well?

Or am I tripping and I am making up that option? lol

If so, I may ask them to send it for the cheaper price and then have a local shop install it who specializes in aftermarket parts as well (assuming they say they can do it after I call & ask)

I had the 2.85" pulley but returned it after research to find out the 3" would better suit my end goals.

Seb was great at answering all my questions (even some dumb ones). The pulleys are definitely worth it, it's just a matter of how much boost you can safely run with the fuel you'll be using. That's where Seb comes in.

You can definitely just purchase the parts from 928 and if I remember right they have a list of recommended installers on their site.

If I do another pulley upgrade I'll probably do the 3" instead of the 2.85 too.

You are right. I wasn't seeing things then. I went to check again on the website and it was definitely an option to do so. A standard or premium? package for half the price. And you dont have to worry about them taking forever to send it back either.
I also would assume any aftermarket automechanical shop could do the install for less than 600 to 700 lol seeing as the blower is small, not extremely complicated, and the kit comes with 6 small pieces.

i think I will go that route
That plus the pulley swaps.

Im wondering maybe since my motor is not going to be stock anymore, I could possibly run a 2.85" pulley safely with Sebz tune?

I also had a question:
Is Sebz tuning like $950 for each time you want your car tuned, or do you pay for a set of tunes that you can use throughout a certain time period...or none of the above?

I'm not sure what the difference is between standard and premium package? I'm also wondering if Specialty Z could do the bearing and impeller install.

Your other questions would be better answered by Seb.

Premium Package:
2 matched Timken ceramic high-speed bearings
2 HSS input shaft bearings
1 Premium High-Speed Mechanical Seal
1 PTFE-coated Viton input shaft seal

Standard Package:
2 input shaft bearings
2 matched impeller shaft thrust bearings
1 Viton input shaft seal
1 PTFE-coated Viton impeller shaft seal

Yup. I asked Seb just not too long ago.

SpecialtyZ, at least Seb has not swapped out bearings on a supercharger yet, but said the wheel is very easy and straight forward to swap out.
