    Honda HR35TT Twin-Turbo V6 engine

    Honda Performance Development Thursday announced a new, 3.5-liter racing application for the versatile, production-based Honda V6 engine found in a wide range of Honda/Acura passenger cars and light trucks and now raced in multiple categories worldwide.

    The Honda HR35TT twin-turbocharged V6 is expected to make its TUDOR United SportsCar Championship debut at the 2014 Mobil1 12 Hours of Sebring, mounted in a Riley Gen3 prototype chassis campaigned by Starworks Motorsport.

    Previously, Starworks partnered with HPD to win the LMP2 class at the 24 Hours of Le Mans and World Endurance Championship in 2012, using HPD's ARX-03b chassis and Honda HR28TT twin-turbocharged V6, which also is derived from Honda's J35 series of engines.

    Starworks becomes the second team to utilize Honda power for the new TUDOR championship. Extreme Speed Motorsports campaigns a pair of prototype class HPD ARX-03b Hondas, after a successful initial season with the same package in the 2013 American Le Mans Series.

    "This is an exciting program for HPD and our customer teams in the TUDOR United SportsCar Championship," said Steve Eriksen, HPD Vice President and COO. "Adding Starworks, a team that achieved great success with us in 2012, in a prototype machine alongside the proven HPD-Honda combination run by Extreme Speed Motorsports provides HPD with a strong, balanced attack in the inaugural TUDOR Championship."

    "It's a fantastic feeling to be partnering with Honda once again," said Starworks team owner Peter Baron. "No doubt we had amazing success with HPD in 2012, but unfortunately it was only a one-year program. We have had numerous conversations over the past two years about building a Daytona Prototype motor and we're thrilled to see it come to fruition. We absolutely love working with HPD and have been in collaboration to find a new opportunity to partner with them again. We will have our work cut out with the steep learning curve to get us to Victory Lane, but HPD brings determination and success to every program it touches. Although HPD already competes in the Prototype class, we feel this is huge step for the TUDOR series and Starworks is thrilled to be part of it."

    Starworks Motorsport has compiled an enviable record in Daytona Prototype competition, with five race victories, including back-to-back wins at Indianapolis in 2012 and 2013; and a second-place finish in the Daytona Prototype team championship in 2012, with two victories and six podium finishes. That same year, Starworks became the first American-based prototype team to win an FIA World Championship since 1968, and HPD won its first world title in WEC competition.

    The HPD-developed twin-turbocharged Honda engines to be used in the TUDOR championship are both derived from the Honda J35 series of production V6 engines, and include relevant twin-turbocharger technology, along with the efficiency provided by direct fuel injection.

    The HR35TT is yet another competition application of the ubiquitous J35 engine. The first, the HR28TT, was designed for LMP2 competition and won in its American Le Mans Series debut in 2011. The engine has gone on to record 24 individual race victories and three series titles in the American Le Mans Series, World Endurance Championship and European Le Mans Series Competition.

    Other variants of the engine have been raced in Japan's Autobacs SuperGT Championship, the One Lap of America competitive rally and Pikes Peak International Hillclimb.

    Honda Performance Development (HPD) is the Honda performance company within North America. Located in Santa Clarita, Calif., HPD is the technical operations center for high-performance Honda racing cars and engines. The company is marking its 20th anniversary in 2013.

    As an engine supplier to the IZOD IndyCar Series, Honda has scored 204 race victories in both CART and IZOD IndyCar Series competition since 1994, and powered Scott Dixon to a series-high four victories and the 2013 IZOD IndyCar Series drivers' championship.

    HPD offers a variety of race engines for track applications from prototype sports cars to karting; and showcases "fun-to-drive" products for professional, amateur and entry-level racers.

    Just look at the exquisite craftsmanship, it just oozes Honda's manufacturing skill.. look at the oil filter its stock the same one you get at your dealerships, its good enough for a stock car it good enough for a race engine.

    Not sure why that intake looks like does. What's with all the torx bolts ?

    Is that because the twin turbos would be creating a lot of pressure ?

    The turbos would generate a couple of bar of pressure so that would make sense. 24 torx bolts seems a little overkill otherwise.

    The only logical reasoning I can see is they may have six velocity stacks underneath the cover and not to get the top cover flex in sudden resonating frequency of pressure pulses during the entire rev range, those twin turbo may be aggressive in the power delivery! just imagine with anti lag:Wink:

    Ok if you insist - I'll be the guinea pig for an engine transplant. It can be the first forum project. I'll start as soon as CJ has ordered the engine. :Niceone:
