200 MPH on the Street

May 16th, 2017

If I were pressed to describe the footage documented in this video, I would simply call it elite level street racing (on the streets of Mexico). It must be considered so due to the extreme speeds achieved and the degree of modification and power capacity of the vehicles involved. The Lamborghini Superleggera featured is, after all, equipped with an Underground Racing (UR) Stage 3 Kit. As if that would not suffice, it also has been upgraded with a set of ported and polished race ready cylinder heads. This very bad girl is capable of producing more than 1,300hp to the Read More

Road Rage – Underground Lambo vs. Hayabusa

April 18th, 2017

Wow! These street bikes move like something from another galaxy! The question is: Are they faster than a highly modified Underground Racing (UR) Lamborghini? Let’s take a look. Even in stock form, a Lamborghini Superleggera is the delight of many car enthusiasts. The mere mention of Underground Racing compounds that delight a million times. The twin turbo kit from UR uses a pair of 67-milimeter Precision turbochargers and a MoTeC controller to increase horsepower from the 600hp range to 1,500hp (1,300whp). These UR Lamborghinis are super fast and in constant contention for all kinds of top speed world records but Read More

Half-Mile Blowout – Lamborghini vs. Nissan

March 31st, 2017

Hello racing fans and welcome to the Rafael Hernandez Airport in sunny Puerto Rico. Today’s action is of the 1/2-mile variety and it is particularly outstanding. Some of the baddest cars and most capable performance firms are on hand to try and claim the top speed crown. Underground Racing (UR) is well represented by the star of the event – a black Lamborghini Superleggera, owned by Richard Fowler. As you know, the Superleggera is pretty potent in factory trim but Richard’s Lambo has been treated to the UR X-Package that bumps output up to the 2,000hp mark. Richard has already Read More

71-Year Old Takes Title at Texas Invitational

October 26th, 2016

They say that racing is a young man’s game and I must say that it has proven true over time. Nevertheless, “they” have never met King of the Streets veteran, 71-year old Bob Helms. You see, the thing is that nobody ever told Bob that he needed to move over for a younger butt to occupy the seat of his Underground Racing (UR) built Lamborghini and (I gotta’ believe) that if “they” did, Bob would tell them where to go. Bob has been racing King of the Streets events since 2011, without a win, so I absolutely love the fact Read More

Quarter-Mile Pass – Lamborghini vs. Z06

July 28th, 2016

Advanced Modern Performance (Dallas, Texas) has built one heckuva Z06 Corvette. It’s so capable that it can claim the title of world’s fastest Z06 in the 1/4-mile with a 9.3-second pass. The question is; can it withstand this Underground Racing prepared Lamborghini? Let’s have a look. The Lambo seems to take the early advantage as the ‘Vette lags back coming out of the hole. Somehow, the Z06 comes back and lays down a 9.5-second pass and wins by 1/3-of a second. The Lambo had the fastest trap speed, posting a 173.58 to the Corvette’s 148.22. AMP is doing a tremendous Read More

TT Lambo Posts 6-Speed Half-Mile World Record

May 18th, 2016

There is an old and popular song that says “The Devil went down to Georgia – Looking for a soul to steal.” If he really did come down to the great state of Georgia, he would’ve been proud to drive this twin-turbocharged Underground Lamborghini Gallardo and steal a handful of records (personal and otherwise). This 2,000hp bad girl turned up at the WannaGoFast 1/2-Mile Shootout (in Clayton, Ga.) and took the track record, the event record, and set a brand new 6-speed world record for the 1/2-mile @ 221.08 mph. This is just another entry in a long list of Read More

Roll Racing – TT Lamborghini Goes 213 MPH

May 2nd, 2016

This car bears the moniker ‘MULLET’ after the owner/driver’s hairstyle. This particular hairstyle is often described as ‘business in the front – party in the back’. Well, this Lamborghini Gallardo LP570-4 Superleggera must save the party for the street because on the strip (during this TX2K event) it was all about business. There are multiple 200+ mph passes. As impressive as a stock Superleggera is, you’ll never squeeze 213 mph out of it in the half-mile. This car has been modified with an Underground Racing Twin Turbo Package. The package includes twin billet Precision 62-millimeter turbochargers with Tial wastegates and Read More

2300HP TT Lambo Huracan Breaks Half-Mile Record 238 MPH

November 18th, 2015

Underground Racing is on the cutting edge in turbocharged high-performance technology and they proved it again at the WannaGOFAST Texas 1/2-mile event in Sulpher Springs, Texas. This awesome looking twin-turbocharged Lamborghini Huracan (driven by KC Howeth) posted a world record-setting speed of 238.6 mph; besting the old record by nearly 4 mph! The previous record holder was Gidi Chamdi and he was also piloting an Underground Racing prepared Lamborghini when he set it. Gidi’s car is a Superlegarra and we know that he’ll be back shortly to carry out his next move in this high-speed battle of one-ups-manship. The Lime Read More

2100HP Twin Turbo Audi R8

October 9th, 2015

This video depicts what is being touted as the world’s fastest Audi. It is an R8 that is stock in appearance. It has all of the amenities of a luxurious street car; air conditioning, power windows, satellite radio, even heated leather power seats. This is a fantastic looking car that manages to claim the title “King of the Streets” at the 2015 Texas Invitational Fall Airstrip Attack – now, that ain’t no easy task. This car gets by with the Underground Racing X Package, a pair of Precision 76-millimeter turbochargers, and it’s riding on Toyo R888 street tires. The little Read More

2100HP TT Lamborghini Huracan Busts 200MPH

July 13th, 2015

Press the PLAY button and say hello to what is being billed as the world’s first twin turbocharged Lamborghini Huracan LP610-4. This lime green beauty showed up at the Texas Invitational Automotive Airfield Exhibition presented by the Texas Speed Syndicate, all the way down in Houston, Texas. Then the gang at Underground Racing proceeded to show out – wrenching the X Package equipped Italian screamer to speeds of over 200mph. Right “out of the box” the Huracan is no trifling street car. It is outfitted with a 5.2-liter V10 engine that produces 602hp. It is an all-wheel drive, 2-passenger, mid-engine Read More
