• Rob Beck N54 turbo upgrade dyno numbers on pump gas - 412 whp

      Mazdaspeed6 had his RB turbo upgrade on his 335 dyno'd and here on the results on 93 octane. Supporting mods are cp-e exhaust, raceland dp's, ams fmic, cp-e chargepipe, bms dci, and a JB4. In his words:

      Hey guys, I just got the drf files in.. Heres the story, I ran 100 percent meth a few months ago and killed my flow sensor so I am waiting for a new one. So we had a dyno session set up this morning and terry and i decided to just do a few pulls on 93 pump, so i did... here was my best of 5 or 6 pulls i did... THIS IS MAP 2 14.5 PSI, no special map, no special tuning at all... Im happy with the numbers for 3 week old 93 pump and off the shelf map 2.. Big Thanks to terry, encinitas, rob beck, and george at ics..

        Really amazing power for 14.5psi default mapping on 93.

        376 torque? That's interesting. I thought the N54 almost always had a really close hp and tq peak number. Love these turbos. I'm saving up! Click here to enlarge

        @ Terry: Give this man some meth and a high boost map and dyno again!

        Very interested to see more of these RB turbos. They seem to be capable of consistently posting high numbers

        these are awesome numbers for ~15 psi. as ppl stated meth and 20 psi damn, i think you'd be near 5xx for sure.

        and yea torque is a little lower than usual dyno's on stock turbos but meh. the area under the curve is great straight torque line all the way thru.

        looks like RB is the way to go.

        Tq is lower this time because he didn't start at 2000 rpm like he did last time..

        GREAT WORK!! 14/15 psi and well into 4xx hp.. very ver nice. these things REALLY come a live past 16 psi.. id be willing to say that once your setup, you will surpass my previous best
