    • PorscheBoost member M3ntal's Porsche 996tt hits 717 wheel horsepower with E85 and HTA 3071 turbos at 22 psi + race with upgraded turbo E85 RX7

      Congratulations to M3ntal for some very impressive results from his stock internal Porsche 996 Twin Turbo. Modifications consist of forge intercoolers, IPD Competition Plenum, custom E85 fuel system, FIC 1100cc injectors, Tial 44mm external wastegates, tial 50mm blow off valve, Hallman Pro boost controller, Sachs 764 PP clutch, and FP HTA 3071 .63 AR turbos. This combination was tuned by Roshan Patel (mafless tune).

      The result? A very impressive 717 wheel horsepower in STD correction on a dynojet on the stock internals. The turbos are good for more power but the tuner (wisely) stated not to push it any further on the stock internals.

      Dynographs and a couple videos are below.










      Mod List:

      Stock motor
      E85 from the pump
      1.5 bar
      FP HTA 3071 .63 AR

      IPD Competition Plenum and 74mm TB
      Custom E85 fuel system (Radiumauto.com dual bosch 044 setup)
      FIC 1100 Injectors
      Tial 44mm external gates on stock manifolds
      Tial 50mm BOV
      Hallman Pro manual boost controller
      Sachs 764 PP, Sachs non-sprung disk, oem DMF
      Mafless tune by Roshan Patel

        Your username sure is fitting for the car. That power is dreamy !

        And +1 on the dyno chart in full.

        Edit: Wait, is this the same 996 in LM's vid a few weeks back ? That race was pretty brutal with your slipping clutch, would be fun to see the spread now.

        The username is because I used to be a big BMW nut. I had a bunch of e36 m3's. 95 avus blue, 98 dakkar 4 door, and 95 nick g turbo'd cosmo. Click here to enlarge

        Heres the graph in full...I think we had some wheelspin on the dyno:

        And yes, this was the same car that ran LM. Clutch was toast and my spark plugs were foul. Car runs 100 percent now minus the wheelspin Click here to enlarge

        That's right, I think I recognize the name from some of the other forums.

        Thanks for the complete graph.

        The RMS issue affected standard 996's more but it still happens on the 996tt, just not as often. Getting up there for the stock motor regarding longevity but if you don't always run it at that boost that will help.

        Ive never read one RMS issue since my ownership. Took my flywheel off and dry as a bone at 40k miles.

        As far as power that's as far as I feel comfortable taking it. That's also with unaggressive timing in it. It's all in the tune and fuel system (which 95 percent of the turbo owners skimp on).

        Ha well that makes alot more sense. I thought you were from the U.K. or something. Nice history of E36's !

        And man that's some serious power ! 400+ @ 3.4k then the crazy jump to 600 @ 4.2k ! What a rush !

        Congrats on getting the car back to 100%. Definitely a beast. Sounds great, can't wait for more vids !
