Honda unveils new 3.5-liter racing engine

Honda is following Ford's lead and debuting the second twin-turbocharged V6 to be used by Daytona Prototypes in the United Sports Car Championship. The wait won't be long to see it on track because the new engine will debut with the Starworks Motorsport team in a Riley Gen3 prototype chassis at the 12 Hours of Sebring from March 12-15.
The new HR35TT engine is based on Honda's J35 production V6 found in a variety of its models, including the current Accord. The racing version benefits from dry sump lubrication, but is still similar to the production version with an aluminum block, direct injection and single overhead camshafts. It is fueled by 100-octane E10 fuel, but like many racing engines, exact power figures have not been released.
Starworks has had a close relationship with Honda since it won the LMP2 class at the 24 Hours of Le Mans and in the FIA World Endurance Championship in 2012 with a Honda Performance Development ARX-03b chassis and Honda engine. We can't wait to see this new mill hit the track, and see how it fairs against Chip Ganassi Racing's EcoBoost-powered Riley. Scroll down to read the press release for the full details.

Honda insiders push for Acura NSX Type R sans hybrid tech

With 500 horsepower on tap from a sophisticated hybrid powertrain, there's plenty to love about the new Acura NSX. If the more performance-oriented elements within the Japanese automaker get their way, it could get even better. Speaking with one of the NSX project's chief engineers Nick Robinson at the launch of the new supercar, Autocar reports that there's an effort underway to develop an NSX Type R. Following a much-loved formula, the more extreme variant would pack even more power than the existing version, unburdened by excess weight. A big part of the targeted weight savings would come from ditching some of the heavier components from the hybrid system. The electric motor at the rear could stay to serve as alternator, starter motor, and flywheel. But the electric motors at the front would go, helping to shed a few hundred pounds. Throw in some lightweight materials and we'd be looking at a considerable weight reduction. It could even integrate some active aerodynamic elements that were excluded from the NSX on the road to production. Though the project may still be a ways off from getting the green light, but Robinson and some of his colleagues are working on prototypes ostensibly to make the case. He and his brother James (a powertrain engineer at Honda) will be driving a pair of NSXs at Pikes Peak this year – one that's as close to showroom stock as the regulations will allow, but the other will be closer to what they have in mind for a Type R. It'll ditch the hybrid system and put an electric compressor in its place to eliminate any turbo lag and produce even more power than the existing model. Now if they can only get the go-ahead from the higher-ups at Honda.

eBay Find of the Day: Ayrton Senna's 1993 Honda NSX

It's not often that things owned by the late Ayrton Senna come up for sale, but the seller of this black-on-black 1993 Honda NSX (aka, Acura NSX) eBay find claims it was once owned by the Formula One legend, and that he left a footprint on the factory carpet that can still be seen today. (Footprint, or vacuum lines?...)
NSX no. T000999 was given to Senna as a gift from his mentor and sponsor, Antonio de Almeida Braga, the seller claims, and it was stored at a palace near the Estoril F1 circuit in Portugal. He also was known to drive two other NSXs, a black one and a red one - the latter in which he was seen often.
The seller claims to have owned T000999, which is still in Portugal, for 17 years, and the 31,000-mile odometer indicates it was driven about 1,500 miles per year on average. Thankfully the car has been kept stock, so whoever buys it can enjoy driving it just as Senna did - that is, if the car actually is what it's claimed to be. If the story checks out, then this is one valuable NSX, which is reflected in the high minimum starting bid of 47,500 pounds ($73,620). There have been no bids at time of writing, but with nine days left in the auction, we'll be keeping our eyes on this one.
