    Big dog battle - 425 wheel horsepower turbo Hayabusa vs 1700+ horsepower UGR twin turbo Gallardo

    Liter plus bikes are pretty damn fast, we know that. Power to weight tends to favor bikes at least stock. This bike is not stock however and is turbocharged putting out 425 horsepower at the wheels on C16. It is basically similar to riding a cruise missile. UGR (Underground Racing) makes some spectacularly fast cars with some of their twin turbo V10 Gallardo's and R8's rumored to be putting out well over the 2000 horsepower mark depending on who you ask.

    This Gallardo is stated to have '1750' horsepower. Based on a quick power to weight calculation it has around 1.94 pounds per horse. The Hayabusa based on a 425 wheel horsepower number and a ~600 pound weight with fluids and the turbo has 1.41 pounds per horse. The aerodynamics of course favor the Gallardo.

    So what happens? The Gallardo wins. Why? Well aerodynamics from a roll as stated and probably because it has more power than is being let on. Taking down a Hayabusa on the highway in a car is an incredible feat. A turbo Hayabusa? Well, that requires something truly spectacular. That is exactly what this UGR built Gallardo is.

    Unbelievable.

    I totally agree on the aerodynamics, but you should probably figure the weight of the Busa rider in too. If they are 200lbs (including helmet, etc) the power to weight ratios are almost identical. The weight of the rider on the motorcycle will have a much larger impact than the weight of the Gallardo's driver.

    Of course the rider matters but without knowing his weight I can only go by the machines.

    There are busas that make double this hp and put it down to the ground. There aren't lambos that make double than this one. Bikes are still steps ahead of cars, just have to find the right rider and bike combo.

    How the $#@! do you control a 400+ WHP bike. I mean what on earth.....My car is nothing to write home about but 400ish WHP in any application is not exactly weak.

    Absolutely crazy power and traction from both of these machines. Wow.

    I agree for the most part but there are some well built LSX's or even BBC's that can rev past 8k with FI. However, to beat a high hp Lambo with RWD car, it is VERY VERY hard but not impossible IMO. Still, Lambos seems to be the best platform for high hp roll racing.

    Are those bikes street legal? Obviously more than 425whp is possible but for a street bike just like a rwd car you approach a point of diminishing returns.

    Agreed, i'm well aware of those builds. Nelsons motors often displace over 10.0 litres and are built for 1/4 mile so they're not built for insane top end runs. I remember LMR built that 2000+hp C6 a yr or two ago but it just couldn't put the power down on the road. I think it did beat a lambo or two the runway event it won though.

    Yes, there are plenty making over 600 rwhp that are streetable.

    Why are they built for the 1/4 mile? Why can't they be built for highway runs?

    The issue is sorting the chassis and that is up to you and whatever you put it in.

    The nose could barely stay down in the lower gears with less boost so i'd have to see them line up. For we can definitively say 425 isn't enough!

    I've watched a lot of their vidz and none of the customers were using the motors for highway/top-end runs. Either street cars or dragsters. The option of running one of those motors for this purpose has been available for a long time so it must mean something that nobody has done so.

    American muscle traditionally runs the 1/4 mile. The clientele is different.

    I'd like to see someone build a roll on car with one of the motors.

    Well,here is my 2cents on this vid,most of you know Im a die-hard bike guy with some semi-fast junk in my garage:

    I (for lack of a better term) "know" the Busa owner and Lambo owner from the forums. The owner of the Lambo texted me a few weeks before the race and was concerned he didn't have enough HP to pull on the bike(WTF?!lol). He was NOT on his full-kill setting&he had no interest in turning the boost all the way up either. So he was down a few hundred HP from his max.

    The bike would need about 500rwhp to beat this particular TTG on what HP the Lambo had that night(IIRC,he said 1600whp),but it would still lose if the TTG decided to go full-kill.

    And that's just a run of the mill 2R(if there is even such a thing.Click here to enlarge)..which the owner admitted to having the "slowest" 2R out of all of them. Im not at liberty to disclose his HP but,its A LOT. He is also running stock ratio gears which has him topping out at 205mph-ish. So from a 60-200mph roll that $#@!er is all out. Others are geared for 220-240+mph,which makes it worse for the bike.

    Sure,there are bikes set-up for the standing mile events that have gone much faster than any UGR TTG,but those guys have zero interest in running a car on the street;Ive asked them,they could care less. Im sure there are drag-only Pro Street Busas(6.xx@20x)that would give them a run for their money,but again,those guys aren't risking running their $100k bikes on a bumpy highway for bragging rights against a $400k car.

    Now UGR has the Stage X,not officially advertised,but its out there&available to the lucky few from what Im told. 2300-2400hp. And nitrous.

    There are a few 2R's out on Long Island that head over the border into Mexico to play...I'd love to get a few pulls in against them but I know the outcome;Id rather not be posted all over Youtube losing lol.
    Who knows,maybe I will before the season is over just to see how fast they really are&possibly grab a ride in the passenger seat.

    Which brings me to this depressing conclusion: No bike is ever going to $#@! with a Stg X. on the street.Its Game Over.Click here to enlarge
    I always had that small glimmer of hope that "no worries,a 650rwhp GT40R Busa will walk that Lambo" whenever I saw a bike get ass raped by Underground Racing. But now its completely at a different level,another league all together. UGR is truly king of the roll races.

    ^^^Thanks for clearing that up. I really couldn't image a bike making enough power to beat a UGR car still being streetable in any sense of the world...the problem is everyone is playing to the strengths of the lambos instead of forcing them to bring it to the track where we've only seen one run an 8.xx pass.

    UGR cars are just not touchable right now from a roll standpoint... There is a huge on going debate on GTRlife, but we have all come to the conclusion... GTR's run the digs and quartermile, UGR cars run the 1/2 mile and rolls. They are just simply on another level of power, and the ability to use every ounce of it in every gear.

    Exactly. You can't beat more displacement plus a higher redline in a lighter package. If they had a DCT...

    Thats why the all new huracan will most likely to be the king of the hill when it comes to roll racing. DCT + Big motor + Big turbos + AWD = GAME OVER.
