Rumors have been floating around for years about a potential supercharged Viper.

It appears that it is finally happening, but it is not a factory built package. Instead, it was developed by Arrow Racing, which has Chrysler’s permission to modify the computer programming. It will be sold at the largest Viper dealer in the country, The Viper Exchange a/k/a Tomball Dodge.


There are actually three different packages:

  • Computer (PCM) only,
  • Computer, heads, and fixed cam
  • Computer and low-profile, Rootes-style supercharger.

Viper Exchange told us that the PCM can handle all 3 packages together. There are no power numbers given for the heads/cam combo with the supercharger added, or, the supercharger package includes the stage 1 and 2 kit. One would assume that the PCM would be part of both the stage 2 and 3 packages as well, as a recalibrated PCM would be needed to get the most out of either combo.

The PCM only package provides a 20-25 HP boost, with a boost in torque over the whole power band. The heads and cam package provides 75-80 hp peak gains, with significant gains from 3000 rpm on up, and again, a significant boost to torque throughout that RPM band.

The supercharger package, also known as “the Sledgehammer,” brings around a 250hp gain, and it looks to be well over 200 ft/lbs of torque gain as well. Sledgehammer indeed!

So, if 645 horsepower is not enough for you, it appears that the combination of the The Viper Exchange and Arrow Racing have the answer for your 2013-2015 Dodge Viper.

This has been a big week for The Viper Exchange owner Ben Keating; first, one of Vipers  he co-sponsors won the GTD class in the 24 hours of Daytona, placing 13th overall, and now this huge announcement for the Gen V owners. Ben has many reasons to smile, and has given Viper owners everywhere reason to smile as well.

While Jeep is being spread worldwide, penetrating every market where Fiat or Chrysler has any presence, Chrysler has been lagging in most markets. Sergio Marchionne recently told Automotive News’ publisher that there will be “limited” use of Chrysler in Europe.

He said:

The cars are too large; the market is too complex.

We’ve got to be very, very careful. We’ve got to be very selective in what we do. Very. It’s easy to fall in love with selling 50 cars here and 100 there. But at the end of the day, you’ve got to pay the piper sooner or later.

Mr. Crain did not ask about branding for Chrysler vehicles in Europe, or follow through on specifically what would be sold. Chrysler’s sales in Europe have been fairly low for years, garnering a lower than 1% market share, particularly since the existing Graz, Austria joint-venture plant was taken over entirely by the Mercedes arm of DaimlerChrysler.

The newly re-organized FCA has two major headquarters — a corporate address in the Netherlands and a tax address in the United Kingdom — as well as U.S. and Italian stock listings, and U.S. and Italian regional headquarters (FCA US and FCA Italy).


Sergio Marchionne told Keith Crain of Automotive News why, during a one hour interview:

  • The Netherlands was chosen to allow American investors to receive dividends without withholding taxes, to give added weight to the votes of long-term shareholders, and to allow dual stock listings in the U.S. and Italy.
  • The UK tax headquarters was chosen, according to Mr. Marchionne, due to the favorable terms of the treaty between the UK and the US. (He did not mention the fact that the UK only taxes companies on their sales within the UK, which, for FCA, are relatively small, saving a great deal of money.)

He also said, “We are fundamentally a North American-driven house with relatively large operations in Latin America and Europe. We are very much a North American brand. … I think there is an understanding now that the future of Fiat and its pre-Chrysler days would’ve been a lot more dubious and more uncertain than one with a combined future with Chrysler.”


Many Mopar racing fans were crushed to hear that the company had pulled their factory support for the Dodge Viper GTS-R racing program after winning a 2014 championship. It seemed that the 2015 endurance racing season would be hard for fans of the Viper racing program.

Things changed when we learned that Ben Keating’s #33 Dodge Viper GT3-R would be returning to compete in the GT Daytona segment for the 2015 Tudor United Sports Car Championship and the season’s outlook got a whole lot brighter when it was learned that Riley Technologies would also bring out a new #93 Viper GT3-R, featuring some drivers from the 2014 GT LeMans championship team.

Mopar fans have two different teams to cheer for in the 2015 Rolex 24 at Daytona, but could the teams really compete in the massive GT Daytona field without the factory support? Keating’s team competed in the GTD class throughout 2014 and even posted a few wins late in the season, but the #33 Viper wasn’t a contender in the big races.

Like many Mopar fans, I was optimistic about the #33 Viper’s Rolex 24 run this year – especially with the addition of Marc Goossens to the team. However, I was excited to see how GTLM champions Kuno Wittmer and Dominic Farnbacher fared in the 2015 running of the Rolex 24. They have proven the capabilities in a modern Viper race car, but there is a big difference between their Viper GTR-S in GTLM last year and this year’s #93 GT3-R Viper.

During the first three practice sessions, the #33 Viper (driven by Ben Keating, Jeroen Bleekemolen, Marc Goossens, and Sebastiaan Bleekemolen) was one of the top dogs in the GT Daytona class, while the #93 Viper of Kuno Wittmer, Cameron Lawrence, Al Carter and Dominik Farnbacher struggled to get out of the middle of the pack. This continued in qualifying, when the #33 Viper claimed the second place starting spot behind only the #007 Aston Martin, while the #93 Viper was penalized for an on-track event that forced that half of the team to forfeit their quickest lap.

As a result, the #93 Viper qualified 16th out of 19 GTD entries, and when the team opted to change tires before the race and as a result of that choice, the #93 Viper started dead last.

In the first few hours of the race, the #33 Viper quickly moved to the front of the GTD field, spending the early stages battling with the front-runners from Ferrari and Porsche. Meanwhile, the #93 Viper spent the first four hours pushing through the GTD crowd, joining the top five in the class and when the first 6-hour segment of the 2015 Rolex 24 was completed, the #93 Viper was in first place in the GTD class while the #33 car had slipped to 5th.

The two Viper teams spent the duration of the second 6-hour stint at the front of the GTD field, with pit stops forcing them to relinquish the lead several times. When this second 6-hour scoring portion of the Tequila Patron North American Endurance Cup had come to an end, the #93 Viper had slipped to second while the #33 car continued to sit in 5th. The #33 Viper would take the class lead shortly after the 12 hour mark, but a few hours later, the car came to rest on the track with mechanical issues. That dashed the hopes of winning the Rolex 24 for Keating as his team, but the #93 Viper continued to be a front-runner.93 viper rolex win

The #93 Viper of Carter, Wittmer, Farnbacher and Lawrence led the class at the 18-hour mark and as the teams entered the final quarter of the race, it was clear that the Viper was the class leader of the GTD field. The closest competitor was the #22 Porsche 911 of Alex Job Racing, and while the Porsche got close from time to time, it just didn’t appear to have the power to overtake the Viper. This was confirmed late in the race during an interview with Alex Jobs, in which he clearly stated that they just didn’t have the speed to catch the Viper.

IMSA-Watches-WebEven with pit stops, the #93 Viper was just too fast for the Porsche to catch up, and Dominik Farnbacher cruised to victory in the GTD class – beating the #22 Porsche by 7.588 seconds and finishing a very solid 13th overall in the 53-car field. The #33 Viper settled for a 9th place finish in class, 23rd overall.

This dominating performance by the Dodge Viper GT3-R teams is proof that the teams can compete in the GT Daytona field without factory backing. After so much disappointment following the end of the factory Viper program late in 2014, the Viper teams look poised to take a run at another championship title in 2015.

A quick “who’s who” on the teams:

Ben Keating and Jeroen Bleekemolen drove Keating’s No. 33 Viper in GT Daytona competition last year.

Dominik Farnbacher, Kuno Wittmer and Marc Goossens all drove for SRT Motorsports in the 2014 season with Wittmer winning the championship in GT Le Mans. Goossens finished fourth and Farnbacher finished fifth. The only SRT driver missing this year is Jonathan Bomarito, 2014’s runner-up in the GT Le Mans point standings, who drove a Mazda in the Prototype Class. Bomarito should have stayed with the Viper; the Mazda lasted only a little over 6.5 hours in the 24-hour race.

Cameron Lawrence drove a Dodge Challenger to the Trans Am TA2 championship last year.

The Dodge Challenger SRT Hellcat is making its mark. The limited edition muscle car accounted for 9% of all Challenger sales so far in the 2015 model year. Considering that the Hellcat’s base price is $14,000 higher than the Challenger SRT 392 and $28,500 more than the Challenger R/T with the 5.7-liter HEMI, nine percent is quite an achievement.

Plummeting gas prices may be having an effect on sales of the HEMI V8s. In the 2014 model year, the SXT with the Pentastar V6 accounted for 53% of all Challenger sales. So far in the 2015 model year, that percentage has dropped to 38% while the R/T (including the R/T Scat Pack) has become the best-selling trim line.



The greater customer preference for Hemi V8s is no doubt satisfying to the factory workers and production coordinators, given the popularity of the Jeep Cherokee and Wrangler, which use the same powerplant (along with the 200, minivans, Rams, 300, Charger, and ProMaster).

2015 Model Year 2014 Model Year
SXT 38% SXT 53%
R/T 31% R/T 37%
R/T Scat Pack 16% R/T Shaker 4%
SRT 392 6% SRT Core 3%
Hellcat 9% SRT8 3%

Toledo may not keep Wrangler

Today, Fiat Chrysler CEO Sergio Marchionne implied that the odds were against the Toledo plant keeping Jeep Wrangler production, despite a recent land purchase and the city’s long history with Jeep in general and CJ and Wrangler in particular. He did say that, if Wrangler was to find a new home, new product would be moved to the plant: … if the economic  [...]

Though the venue, an off-road vehicle park and various city streets and highways, was chosen by Jeep, Mr. Rall was able to choose his route through the obstacles to get  [...]

The dual-minivan plan, revisited

Rumors from Windsor suggested first that the current “RT” minivan body would continue for some years alongside the new “RU,” and then that it would be dropped as soon as the new designs came out — in Chrysler form only. Sergio Marchionne has thrown some fuel onto the speculative fire, commenting today in Detroit that: Where is Reid [Bigland]? If it  [...]
