    VGT compounds

    As in being used in the valley, or as the second turbo? Kidturbo, we have a cummins isx 15L, 600hp with a variable holset he551v turbo. 2 of those in parallel would definitely get you your 1200hp, not sure about your low end though.

    VGT compounds

    Im not aware of any vnt turbo capable of 1,100hp by itself. Even factory 1,200hp engines are using compound setups on each bank. By going parallel, your going to be using a smaller turbo early in the rev range, and then switch over to the large turbo later on? Or are you running a turbo on each...

    VGT compounds

    Was doing some research because i think the gt4202r turbo i have will have a too small of a turbine for compound use. Started looking into swapping in a gt45 turbine wheel and found that garrett makes a vgt 4502 turbo used on the 14L detroits. Has anyone ever heard of using 2 vgt turbos in a...

    S480 turbine

    Must be a turbo design problem, one problem i could see would be differential thrust being put on the shaft. Ive run a 609 size caged ceramic bearing up to 200k rpms with no issue, for minutes at a time. I even run an .011" oil restrictor on my one with 0 issues the last 50k miles.

    S480 turbine

    Ive used garrett bb turbos before but upgraded them with ceramic bearings and had them vsr balanced WITH oil and they have performed phenomenally. Garrett claims they arent rebuildable but thats so they can sell you another turbo. If you take out the shitty steel bearings and replace with...

    S480 turbine

    Thanks mike, I want to stick with garrett bb chargers, and im only going for 800-1,000hp and still be able to tow and do daily work duty.

    S480 turbine

    What size turbine is everyone running in their s480s in thier compound turbo setup? Reason i ask is i have a garrett gt4202r with an 82mm turbine and a 1.0 tial vband housing. Im worried the turbine is going to be too small and cause excessive backpressure. I was thinking of getting a gt45r...

    Best Billet s475?

    The tests are being done on the same truck on the same dyno, with video taping of the dynos computer for visual proof. I dont know all the turbos theyve tested against, but i know theyve beaten haisley machine and bullseye i think. they machine there own wheels so they can tweak and tune a...

    Twin turbo boost levels at higher elevation

    Your build sounds alot like what im going after, how does that setup do towing? 55psi is what most guys run at around here at 780'.

    Best Billet s475?

    JEB modern machine is only a mile from me and i know the guys personally. There new prototype compressor wheels are amazing and is showing on average a 60hp gain against competitors exact same turbo. Names dont make good turbos, good science/mathematics does. But in the end it comes down to...

    Garrett powermax turbos

    Already working on it, thats why i was suprised when i saw the powermaxs advertised as bb cause i always thought they were journal. Im planning on adding watercooling and using cageless angular contact ceramic bearings. Similar to how garrett does it but much better quality bearings.

    Garrett powermax turbos

    Are the powermax's different than the factory ones? You build 40-60 a month (thats alot) but are any of those the "powermax" turbos? Im in no way questioning your knowledge mark, it just boggles me that garrett would advertise a bb turbo when/if it really isnt. Garrett does make a ball bearing...

    Garrett powermax turbos

    http://m.thoroughbreddiesel.com/store/p/5750-Garrett-PowerMax-Stage-1-Turbo-04-5-10-GM-Duramax.aspx Says its a bb upgrade right in the first sentence... Im not defending them, i thought they were journal bearing too, other places show it as a bb turbo too... Garrets powermax website...

    opinions on lly build

    Your shooting for the same hp as i am, im up to $16k in just parts and thats buying as much used as i can. Thats just parts, no labor, fluids, gaskets/seals, and little knick knack parts such as boots, clamps etc. Best thing to do is just read, theres so much info and knowledge here itll keep...

    Thinking of trying something different.

    A 2560 on 3.3L isnt uncommon, a 2860 would leave more room on the table for sure. I have a 2863 on 2.8L and it doesnt spool up good until around 2500rpms or so. Guess i should note that im only going for 800hp max with towing being my goal in mind. I know i could buy a kit and do it like...
