    kinda curious

    so lets say 400whp....

    how much boost would it take Matt to make that? and how much torque

    vs

    how much boost with the KA, and how much torque

    with identical turbos; the ones you stated above

    rx7-8.89@157mph

      gt3076r, 18 lbs , high 200's for torque.

      now this is with a small .48 turbine

        on the KA, you will see ~400whp @ roughly 19-20psi, hitting full boost by roughly 5k-6k rpms(dont quote me on that....) depending on setup. That should net you depending on tuning, about 350ft-lbs of torque.
        this would be the gt3076r with the .82 a/r turbine

        here is a dyno from some guy down in georgia that has a similar setup to mine....

          Ivan has 40psi on his gt42 sooner then 6k.

          you should have around 20psi at like 4k.

            eh maybe...like i said not too sure about that...i thought it would be about 4200-4400 from when i did all the calculations from the compressor map, but i wasnt sure if i figured right.

              you do remember how fast my turbo spools. and yours should spool around the same as mine does. The DBB should somewhat make up for you having a .82ar

                ball bearing doesn't mean faster spool...... you should know that faber...haha

                  well in a round about way it does....it takes less force to spin a DBB cartridge than it does to spin a ceramic journal bearing cartridge...which means the turbo wheel will reach higher speeds faster...which means the compressor will flow more air faster = boost faster.

                    Yes, i know this. DBB makes the turbo more efficient, also get more devoted lubrication and coolin. and then what nate said.

                    I would be hard, but if you have 2 identical turbos one with journal bearing and the other with the DBB, 95% of the time the DBB will spool faster then JB turbo,

                    WITH ALL THINGS BEING EQUAL

                        thats interesting, thanks

                        for comparison here is what your typical 13b rew will do

                        here is a graph of a typical single setup.... gt 3582r---1.06a/r

                        13-15 psi, 320-340lb-ft, 400rwhp, full boost 4k

                        you need alot bigger turbo for the same power.......

                              Hopefully by next summer you will. Almost have enough saved for the rebuild.

                                      Not everyone wants an enourmous turbo that needs anti-lag to spool and a million hp...some want something that'll work good for auto-x

                                        180hp is just fine for auto-x. driver skill and supension are WAY more important then power.

                                          god....

                                          if i put a turbo as amall as fabers on my car it would act like an NA car....... there would be boost all the time, way more than fabers car even

                                          all i am saying is that a rx7 with even just the stock turbo system has waaay more potential than a NA one in anything.... and that he should look into that as it is cheap and very effective

                                          I never said a word about a large frame turbo did i??

                                          I dont care what anybody says.... my car even with a very large turbo is going to beat an NA 7 even in auto-x, not doubt, if the rest of the cars are set up the same, same driver skill

                                          OH and bubba, so you know i pulled a 1.5 60ft without antilag, and i can spool a 42 like a 2jz... hmm

                                          rx7-8.89@157mph
