    Just got off the phone with Cotton's performance and they told me that my new turbo and all the new turbo's will be double ball bearing. And all the new turbo's will be the new F1 wheel. :biggrin:

    No no no........ wrong info, the Turbonetics turbos are single Ball Bearing.. must have misunderstood Gerry, or he misunderstood himself... :eek: The F1 wheels are correct, all Tnetics have them as well as some of the other Turbo builders out there are beginning to use them..sorry for the confusion, this is Jack, give me a call if you'd like..

    So Jack is right. I called them back and Gerry said is was, and Jack was unable to talk at that moment. So I spoke to Turbonectics, and he said it was a single bb. Sorry guys.

    Patrick, I'm considering a GT6765 BB .63. On the compressor housings, is there any compelling reason to go with one over the other? I am specifically looking at the E and S housings. FWIW, I have "3000 stall" 9/11, though it regularly goes 3200-3400 when I boost up at the line... higher at times

    I ask because right now I have a 4" CAI leading to a 3" MAF and pipe to a PTE-52 with the 3" inlet. All good, but the 2" outlet feeds 2.5" IC piping. Seems like a waste, but is it worth the expense to go to a 4" inlet in order to get a 2.5" outlet? I mean, what would be the appreciable gain in regards to spool up or power?

    As I see it, with the S housing I would also need to get a 2.5 turbo to IC hose, a 4" MAF pipe like the Buickgn.com 4" INLET Pipes with the insert to get down to the correct ID for the MAF. I suppose at that point I might put in a 3.5" MAF... why choke it with a 3"?

    Your, or others', thoughts?

    S cover will have cooler charge temps than the E cover, as will the H cover have cooler temps over both the E and the S cover.
    Slightly slower spool up tho when comparing the E cover to the H cover. Exactly how much, is not known. You can run 3" piping to the S cover, however, it would be best to run 4" piping on the S cover. 4" MAF pipe is a must for the H cover tho.

    Dean,

    I sent you a long e-mail.
    Let me know if you have any questions if you are still awake after reading it.

    LOL

    What about E vs. S? Negligible difference spool and power wise?

    Twin Turbonetics

    So far no twin peaks on my setup. Jack, our twin-turbo '69 Electra was just accepted as the official show car for the Tuskegee Airmen.

    The Faithful Pursuit will be on display at the Palace Station Hotel and Casino in Las Vegas, NV, August 6th - 9th.

    We have a lot of work to do. Going to Indy next week to talk to Tuskegee Airmen's racing guys.
