    • Urban Hotrod builds a 8000 rpm 3.8 liter 996 turbo using E85 tuned by Magnus Motorsports with HTA3586 turbos - 700+ whp on low boost

      Here is an E85 996 3.8 liter build by the Canadian shop Urban Hotrod. The shop contacted PorscheBoost.com to share this build and we are glad they did. This 996 turbo features increased displacement to 3.8 liters from 3.6 and is tuned by Magnust Motorsports for E85. The turbochargers are upgraded to twin HTA3586 units which provide a very large power boost allowing the car to hit well over 700 horsepower to the wheels.

      Urban Hotrod told PorscheBoost that the car did 780 wheel horsepower at 18 psi of boost which is a low boost setup. The graph sent only shows 704 wheel horsepower but the car is still being tuned and was not run to redline. That power figure was hit at 7200 rpm but the motor is built to rev to 8,000 rpm. Final numbers are eagerly anticipated!

      For now, dyno graph and dyno video below.

        I have a friend that just pulled his Pro___ out to install the Syvecs. Had issues like crazy!
        the Svyces it a very user friendly ECU.

        AMS had just changed from PRO___ to the syvecs and just shattered the world record yesterday.

        pull up SYVECS they posted it today. Still cannot load links
        There's a thread already on the new GTR record. I'll check out Syvecs.

        How much is the ECU?

        More expensive but you definitely seem to feel it is worth it.

        a good tune from a Well know shop will cost you 2500.00 and that is not 100% its 85 Tops. So if you change stuff you get 2 updates then you have to pay again to get a new tune. this way you can tune with no issues.
        It has Boost by gear, Antilag, launch control Flex fuel and lots more.

        Are you re-routing the intake into the intercooler pathway? Just wondering cause I've heard mixed opinions about this.

        Also, have you guys done anything with the 997 motor?

        Looks good
        That's stock intake manifold..right?
        I really like how the power extend to 7800rpm unlike 997tt intake manifold which start dying at 6600rpm on high boost

        Don't think the intake manifold is responsible for that dip.... More a tuning/supporting mods/VTG turbo/turbo inlet piping restriction on OEM cars
