    • DOC Race Precision 6466 single turbo N54 with meth injection makes 826 whp at 35 psi

      The Doc Race N54 single turbo manifold is a work of art. It also performs as these dyno runs are evidence of. EMP Tuning did the tune on this car along with the dyno runs and there are a few things that should be questioned.


      First of all, what is with the tiny low res graph? Are you people professionals or not? Post a full res shot. Even better, if you are new and not exactly regarded as a high end shop post the run files to eliminate all doubt.


      Is this a powerful N54? Absolutely. Is it making 826 whp? Not exactly. A spike on the dyno run is responsible for the higher peak figures.

      Not that the Doc Race manifold can't flow for 800+ whp or that Doc Race is somehow responsible for how a shop posts dyno runs.

      This is a product of the social media era where people think they can take some crappy cell phone pic and pass it off as a record or achievement. It's lazy, lame, and unprofessional.

      It should be noted that these figures are hit without port injection and with methanol injection.

      Doc Race's N54 kit shows it is capable of making a ton of power once again and remains one of the highest quality options in the N54 aftermarket.

        LOL, another DocRace dyno graph with speed as the bottom axis. When you absolutely positively want to hide $#@!ty spool. Speed as the bottom axis is the go to...Click here to enlarge We wont bother to mention the speed is going up to 160, so its a 5th gear pull. Looks like your #1 installer loves to pull out all the stops for inflating dyno graphs...Click here to enlarge Go ahead, and remove me like you do with your all your other threads for speaking the truth...

        Damn, saw the title and thought it was going to be upgraded HPFP results or something. That must be a firehose of meth, but nice results.

        Interesting. They told me this was a VM kit lol. Anyways that 826whp is just a blip at the end of the run. I wouldnt claim 826whp. Its more of a solid 780whp until it starts oscillating IMHO.

        It is a DOC kit. I think this car used to have a VM kit. The shop car "Kragen" also used to have a VM kit and is now installing a DOC Race kit.

        Nice, what gear was this on and what is the correction factor?

        I'm assuming this is on race gas, so it's running roughly 200-250whp worth of meth which is super risky. Even at 150whp worth of meth, my meth pump was struggling to keep up not to mention cylinder distribution risk. The fueling side has nothing to do with the turbo kit, however.

        fueling has nothing to do with the kit but I know people are going to ask so is why I give all info that I have.

        Another customer had VM and went to Doc and lost a good 500rpm in spool. So Im not too sure why Aj sold his VM kit.

        I talk to Aje on a daily basis. This is a DOC kit. Aje sold his VM kit and bought one of mine this month along with a couple more of his customers. I doubt he would do that if our kit performed less than VM. Just saying. Not bashing on VM, they make a solid kit.

        Idk, it looks to me like a VM kit.. I could be wrong though. BoostedBilly is the Instagram SN if you want to look at it.

        I'll try and dig up some logs I have from 3rd party customer. I'm just going by the data that is presented to me and what the customer says. Click here to enlarge

        Why is RPM not plotted and the screen cropped on the bottom?

        Because it's mph and they want to hide it.

        when you post something that pretend to be another world record - be little bit more professional and stick to simple rules:
        - list specs
        - post proper snapshot from dynostend
        - post your log
        ... i think this minimum info can be shared between the community, or I'm wrong? otherwise i would call this thread "DOC race claims 862 whp - lets discuss" Click here to enlarge
