    • Tuned 2017 Porsche 911 (991.2) GTS vs. bolt on Nissan GT-R rolls

      It is good that PorscheBoost Porsche Performance Forums member @LavaGTS got these runs on video or nobody would believe him. For some reason people are still having trouble believing the 991.2 3.0 platform is stout when it comes to tuning and really a discount 911 Turbo. There is a reason Porsche tries to lock people out of the ecu, right?


      Well, usually you would need a 911 Turbo to dismantle a bolt on GT-R like this. The GT-R gets the jump in both run videos yet the 911 GTS walks away and it does so quite easily.

      The larger GTS turbochargers show what they can do and this is a car with just an OTS pump gas tune, Fabspeed headers, and cat deletes.

      Now imagine a race gas tune or larger turbochargers than factory...

      Porsche 911 GTS:
      Headers
      Cat Delete
      Stock Muffler
      Cobb Stage 2 OTS tune
      3.0 Twin Turbo, PDK Transmission

      Nissan GT-R:
      Intake
      Full Exhaust
      Tune
      3.8 Twin Turbo, DCT

        Pump gas? Cobb tune and AMS intercoolers right?

        I thought he has Fab headers too. Nice walk!!!

        Figure something is off with the GTR because it wasn't much of a race

        Sorry, GTR was tuned for E54

        My car is running the 93 map.. I had half a tank of 95 and added 1 gallon of e85 into the mix.. Not sure if that helped or not but I was a little worried I was gonna mess something up.

        If you look carefully at the boost gauge at the top left of the GTR center display, you will see it hovers around 10psi, which is lower psi than stock let alone modified. A basic tuned gtr should peak @ x>17psi....

        That's weird. Oh well, it is what it is.

        The driver said it was boosting around 12-14psi.. What's going on here? I knew something was fishy about "600whp".. We both fueled up at the same gas station and I watched him pump E85.

        600whp in a GTR on E85 requires close to 20PSI of boost.

        If you look at his boost gauge at the top left of the center display during the run you will see boost hovering at 10psi(which is less than a stock 480hp 2010 GTR)

        why would he fill up with E85 though?

        Is that gauge even accurate?

        I'm guessing he had a boost leak.

        I dont know, e85 gtrs trap between 135-140mph on a decent tune. They need close to 20psi to do it. The fact that he told the gts driver he was running 12-14 means something is entirely wrong, the fact that the center electronic boost gauge reads from the ecu and is showing 10psi confirms this is one messed up GTR probably running in LIMP MODE

        You would think the dude would know his car wasn’t right and not race if knowing so.

        Anyway, maybe they can rematch or he can run some other cars as it’s just taking away from how potent a tuned GTS is.

        The GTS DID have a 700 pound advantage given the GTR had a passenger.. Still though, I thought it pulled too hard.

        The driver of the GTR said he was tuned for E54.. Don't want to bash character but the guy might be a poser because the GTR looked really riced out. His best time at the track was 12.1 too. He bought the car with the mods 2 years ago and all he did was add stickers and an ugly wrap.

        There's a no fly zone event coming up that he might be attending.. Got myself a cool go pro for christmas that I'm going to use for videos.

        I am pretty sure a 12.1 in the 1/4 Is with turbos removed, lol.

        More like 14's.

        I just don't get why this guy went to race with a supposed boost leak or didn't know his car?

        Either way, that GTS is running strong.

        Most people dont realize a stock gts is a strong platform to begin with , it can trap 125mph , roughly the same as a 991.1 turbo .... but you do $$$ for it!

        What's done to the GTR?
