GTC GT-R Runs 10.8 @ 126mph with Latest AccessPort Tweaks

The guys over on NAGTROC have a pretty interesting discussion going regarding custom tuning of the staple GT-R ECU upgrade, the Cobb AccessPORT. The guys have figured out how to write maps that control boost pressure based on RPM.

While this doesn’t sound like much when described like that (and there’s probably more to it), its actually quite a big deal. What it allows the average GT-R owner to do is to get more tuning value from their Cobb AccessPORT before resorting to electronic boost controllers and aftermarket wastegate actuators to keep the GT-Rs small turbos from boost spiking, especially on gear change.

The guys at GTC Racing have used the latest code and maps on their GTR to run 10.8 @ 125.92 mph at Santa Pod drag strip in the UK. This car is fitted with neither a boost controller or a set of actuators. It’s also running street tires but is fitted with a full turbo back exhaust and Forge Motorsports upgraded intercooler.

    Very nice!
    But I think R35s are never going to touch 1/4 mile times of previous generations tuned GT-Rs
