    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.

    Is the motor "built", or is it just increased displacement (I KNOW, they're getting an extra 1k in RPMs vs a completely stock motor). 700 WHP could be done on a stock 996 motor with a turbo upgrade & knowledgeable tuner. Looks like they're using a standalone also

    When you increase displacement you are changing the internals so why wouldn't you go with stronger internals? Yes, it's built plus it is revving to 8k rpm which si higher than the 6500 rpm stock redline.

    This is 700 whp on low boost and not run to redline...

    I 100% agree, which is why I was surprised that it only made 700 WHP. Just Google'd the specs of the HTA3586s & they're similar to the Precision 6262s SO​ there's a lot of turbo left

    I wouldn't post this showing it only makes 700. Its cool it goes to 8k though. But they need to make some more powa! Then it would be impressive.

    They sent it to me. I'm sure they will send me more. It's pretty sweet regardless.

    I'm not sure what is going on when 700 whp on low boost not running to redline isn't impressive.

    Absolutely, its "impressive" it just needs to fully perform! Either way, looks promising.

    Is this 700whp AWD or RWD? Can't see the front roller in the vid to tell if it's spinning...

    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.
