Yamaha Genesis 130 FI

Here is a power and torque graphic for the Genesis 130 FI (fuel-injected three cylinder 1050cc four-stroke) found in the all-new 2008 Yamaha Nytro FX models.
The addition of fuel injection and the increase in displacement yielded a 16-horsepower gain over the Genesis 120 engine it is based on. “We built this engine with an eye squarely on the ISR Stock 600 Class rules”, said Yamaha Snowmobile Product Manager, Adam Sylvester. “We wanted the new engine to be fast-revving and powerful for both competition and for consumers. We got everything we had hoped.”
Yamaha brought a preproduction Genesis 130FI engine and a full-production Genesis 120 engine to (our old friend Olav Aaen) at Aaen Performance’s dyno testing facility for same-day, back-to-back testing in order to determine the extent of the performance difference.
Peak horsepower figures were 138.6 HP on the FX Nytro and 122.6 HP RS Vector. Both engines showed a very similar curve profile, holding their respective peaks for several hundred rpm.
Torque showed a similar gain, from the carbed 120 to the fuel-injected 130. The Vector engine showed a peak torque figure of 82.9 foot/pounds. The FX Nytro
engine pulled 94 foot/pounds at 7100 rpm. “That kind of torque is near what consumers have found in competitive big-bore 2-stroke engines in the past,” said Yamaha Snowmobile Marketing Manager, Rob Powers.
The Genesis 130FI engine also showed a huge gain in torque down in the low end. At 3500 rpm, the new engine posted nearly 72 foot/pounds of torque. That is a 17-point improvement over the Genesis 120 engine. “Consumers are going to absolutely love the high torque this engine puts out at clutch engagement,” added Sylvester. “The reason is this engine’s amazing low-end grunt.”
The torque curve is what you feel when you squeeze the throttle. The new fuel-injected triple comes alive quickly and with authority, delivering a wide torque delivery all the way from a grunting 5000 RPM, rising quickly and peaking at about 95 pound-feet of torque at around 6,000 RPM, remaining strong through the entire operating range.

 

USSA Races Return to Ironwood

The roar of snowmobile engines will once again fill the air at the oval track at the Gogebic County Fairgrounds in Ironwood, Michigan as U.S.S.A. racing returns January 5-6, 2008.
The “Snowmobile Olympus” will once again have top billing as the first race of the season. Not only will high-tech racing machines roar around the track as part of the USSA racing circuit; with the addition of Pro Vintage Racing, sleds from the 1970s and ’80s will again line up to race.
“It’s another community event, and will be held in cooperation with events such as the Superior Sno-X, Copper Peak Hill Climb, and the Eagle River Snowmobile Derby,” stated race organizer Don Bertels, noting officials from Eagle River are in full support of bringing USSA oval racing back to the fairgrounds in Ironwood.
For years, the Snowmobile Olympus in Ironwood was slated as the season’s opener. USSA snowmobile racing pulled out of Ironwood in the early 1990s. Races were then held in Bessemer for a couple of seasons. By 1996, USSA racing on the Gogebic Range had come to an end.
USSA Executive Director Ted Otto, who was flagman at those races, said the USSA is excited about bringing the race back to Ironwood. Otto has been working with the USSA for nearly 40 years.
Otto stated, “We raced there for years and years and years. It was always the season’s opener in the early days. We always looked forward to going to Ironwood, and we are very happy that people are going to bring it back.”
Otto said the Gogebic Range lends itself to early racing. “It’s a good place to start our season and the people have always been supportive of snowmobile racing,” he said. “That makes it really good. The drivers will be very excited about coming back to the Ironwood area.”
Otto reminisced about some of the drivers, and said a Legends Race is possible. He said event organizers and the USSA would like to bring back some of the big names from the “heydays” of the Ironwood Olympus — including Jacques Villeneuve, Steve Ave, brothers Jeff and Greg Goodwin, and the Trapp brothers, etc.
He said they hope to “bring back the stars of yesterday. We hope to bring back everyone that was ever there, including drivers that raced in the junior classes.”
When USSA returns to the fairgrounds, some of the racers will have already raced in Ironwood. Some will be newcomers to the track, made up of the younger generation whose fathers raced in Ironwood, Otto said.
USSA families are very aware of Ironwood and the activities that took place at that track, Otto said. “The track was always very good.”
Charlie Goodwin, father of the Goodwin brothers, is excited about bringing USSA racing back to the fairgrounds. “It’s absolutely superb. It was always great racing in Ironwood.”
Goodwin said he isn’t sure if either Greg, now 51, or Jeff, 44, would mount their racing sleds again.
Community support for bringing USSA racing back to Ironwood has been excellent, Bertels said. “We will depend on a group of volunteers, as in past events, and sponsors of this first race of the season will also be a very big part of the event.”
Bertels said the fairgrounds is a beautiful facility. “The success of the Olympus will allow us to continue with improvements.”
