    First one

    Well Looks like i will be the first A-trim guy on here. I am new to the supercharger world and will have lots of questions. I actually havent gotten to drive my car with the supercharger on it due to being in the middle of my 5lug 4 wheel disc conversion. Well hope this site really takes off

    a-trim is a great start... i did the same and eventually bought the ho upgrade kit from vortech (alum discharge, bypass vavle, msd btm, t-rex, larger crank pulley, 8 rib blower pulley). recently i had the impeller changed to the s-trim.

    good luck with the blower, its a lot of fun

    A-trimmer checkin in

    I just installed an A-trim (actually the new SC-trim replacement to the A) a couple months ago and I love it! Will be installing more go fast goodies soon in the neverending quest for more ponies.:D

    I think the HO upgrade is around $500 (by sending the unit back to Vortech to convert to S-trim status). One of the A-trimmers at the Corral site (with the straight vane impellers) indicated he was getting 7.5 - 8 psi with a 7" crank pulley and powerpipe. I'm guessing the sc-trim may get alittle more but not sure. I'm gonna get the 7" pulley in the next couple of months.

    the ho upgrade is different from the impeller upgrade.

    i paid ~500 for the ho kit, and i paid 814 for the s-trim upgrade

    Damn Shifter! Well I'll wait a little. I have too many other parts awaiting install and no time! Looking to install my in-tank high-pressure walbro and various other fuel system upgrades prior to increasing boost. And a couple of induction parts. Hehe

    Did you get that bypass installed yet?

    What kind of boost were you seeing before you upgraded to S-trim status?
