    • How much power are the Stage 'X' package UGR (Underground Racing) twin turbo V10 Gallardos / R8's making? This much

      Underground Racing has a bit of an ace up its sleeve. Most people are aware of an 'X' package above the 2R but little is known about its power output or components. BoostAddict was tipped off from a source that will remain anonymous as to the power capability of the 'X' cars.


      A minor debate raged on the forums as to who has more power Heffner or UGR and the peak number on the dyno pull below show it is not even close. It takes well over 2000 wheel horsepower to play with the big boys these days.

      We just recently saw the GTR crack 2,000 wheel horsepower although it maxed out the dyno so its actual peak horsepower number is higher. How much higher? Well, likely not this high. It is safe to say UGR is the power king and getting ready to lay waste to the opposition.

      2015 is going to be a lot of fun in the high performance realm.

        Wow. I'm not terribly familiar with the UGR builds other than seeing crazy videos on the Internet. Is this something where the engine gets rebuilt after each mile event or the tranny only lasts a few events? Or is this actually drivable where they can put a year's worth of events/races on it without a major rebuild?-Rich

        Am I the only person annoyed at not even making half of this output?

        No you are certainly not alone on this. I can't wait to see it in action

        It would be nice to see a Bmw making that kind of power , or at least half that. Click here to enlarge

        Half? I'd bet 98% of the cars on this site don't make a quarter of that.

        1/3 here, lol

        Insane. I'm signed up for the Florida WannaGoFast event where a few UGR cars should be attending. I'm hoping to get a ride in at least a 2R.

        What I want to know is how do you spool turbos that big and that far from what is a relatively small motor. Rev it to 12000 rpm? But why is it always lambos and gtrs winning these events? Doesnt anyone else want to stuff this drivetrain in a prius and go destroy some egos or am I just crazy?

        I'd have to imagine they're using nitrous to help with the spool. This thing is making more at each wheel than bolt-on C7 z06's are making in total... absurd.

        Is 5.0/5.2 really that small?

        I am assuming that photo is not actually an X build as those are not 1350WHP turbos, the turbine housings are too small

        It is a photo of an X build but they could also be sandbagging in the photo itself like they have been with the numbers.

        It doesn't look any different than any of their other builds really.

        Its a fun ride, that's for sure!

        The built motors are pretty stout. The only thing that ever needs changing is spark plugs after every run.

        The GTR is a perfect platform for the dig race and the lambo for the roll. I just don't see anyone else beating them anytime soon.

        As far as spooling the turbos, quite easily to be honest. When we built my car I wanted street power to just do stupid crap lol. I went with dual 62mm precision turbos, and brakeboost to hit full boost at 3500rpm! Tee Hee Hee....its a blast.

        Pic above is missing heads etc

        Well for a production car this day and age its actually pretty large but when you compare it to other motors at this level of power, especially in the world of drag racing, most people are well over 500 ci or even 600 ci like many of the nelson racing engines which are in the 10 liter range. I believe that saleen s7 over in russia also dropped its original v8 for a 10 L motor in order to hit its own 2500 whp goals. I still prefer the smaller motors though, keeps them exotic and makes them more of a "street" car to me

        The dedicated drag motors are of course much larger as you point out. They likely are more reliable at the lower HP per liter as well.

        This is fun because it's a production motor being taken to the limit.

        If starting with a blank canvas you can of course do more. Nelson Racing could probably give you 4,000 hp if you want.

        Totally agree with you there, and its part of the reason id love to buy m10 4 cylinder one day just to try and push it to the raged edge like bmw did back in the turbo f1 days. Its a shame they dont still do anything on that scale anymore

        This is insane, somehow was not aware of this X package. Of course, and this almost seems insane to say, doesn't surprise me too much. If they can get well over 2000 whp out of a 4.1 liter V6, then getting this much out of a 5.2 V10 shouldn't be impossible. But still...this is mind-blowing. I need a Gallardo....

        kinda for a v10 i would say. just because the viper is 8.0-8.4 depending on year but that is considered an abnormally large v10 as well to my understanding.

        The standard for what a fast street cAR is has changed so much in the last 5 years it is insane. I can't imagine what driving a car like that must feel like.
