    • BigBoost first to push the B58 past the 800 wheel horsepower mark - World's most powerful B58 at 822 rwhp

      BigBoost setting B58 output records is nothing new. The records just feel new due to the influx of Toyota Supra B58 tuning. Do not forget BigBoost held and continues to hold the B58 output record and was the first to crack the ~700 wheel horsepower mark.


      Well, they are in the 800's now:


      Apologies for the low resolution graph but that is all we have to work with. Hopefully @Juan@BigBoost-Billet posts a higher resolution graph for us.

      It seems to say 822 rear wheel horsepower with the BigBoost Stage 3 turbo kit and a built motor.

      The curve actually looks quite nice with a smooth torque curve that progressively drops toward redline.

      We all would like more details such as the fuel system, boost, transmission, etc. Hopefully @Juan@BigBoost-Billet chimes in soon.

        Wish we can get a graph that starts at like 2k rpm instead of 5k and actually shows RPM instead of MPH.

        Still very impressive for the B58, that did not take long.

        Yes, definitely want a better graph for this. Weird, considering what an achievement it is that we get this low res graph.

        Regardless, you can see 130 mph is roughly 5252 rpm.

        Isn't it weird how records always seem to have $#@!ty images fact half cut up dyno plots etc?

        I too would like to see the RPM.

        What does that Master Power turbo flow in lbs/min?

        Not sure where you took the graph from as I posted full res graph, lol

        I couldn't dyno below 3500 RPMs as it would go into limp from maximum acceleration exceeded so it must be upped gradually to 3.5k then go wot. I will try and work out how to dyno it from 2k

        Fuel is supplied via meth kit with 2 large nozzles, a dual nozzle TBI and rescaled fuel supply tables in BM3, holding 2900 PSI in the HPFP system, 65x98 turbo, flows for 90 lb/min in dual ceramic ball bearing on a low compression engine with stock bore and stroke

        We set the boost to 29 PSI peak dropping to 27 PSI

        Social media. I couldn't find the full res graph elsewhere.

        Thank you for adding the graphs and details as this is huge news!

        Oh, and congratulations!

        What is the compression ratio?

        TY!

        Nice numbers. Any plans to go with a larger turbo? What's next?
