When the Jeep's engine is under stress, such as when you climb a steep incline, the clutch disk can shatter or the engine may shut off suddenly. This can be fixed by adding weighted inertia rings to the back of the flywheel. This does make the engine work harder to accelerate, but makes it easier to operate on inclines.

You can add a supercharger to the Jeep 4. A supercharger is an air compressor that will use forced induction to get more air into the engine. This will greatly increase the amount of work that the engine is capable of doing, which increases the power. Another way to increase the amount of air into the engine is to increase the stroke. The more air that goes into an engine in one complete cycle, the more work the engine is capable of performing. The total air in one cycle is referred to as displacement.

When you increase the stroke, you increase the displacement. This can add a significant power upgrade to the engine.

Cutting weight was Murray's main objective with the T. As such, every part of the car is meticulously analyzed to ensure it's as lightweight as possible.

The experience was so overwhelmingly positive, I simply HAVE to offer a review. The booking process was easy and our representative (Sigfus) was helpful and professional. We received our literature early enough to research and plan our trip. The itinerary was well thought out and helped us ensure we weren't missing anything. An pleasant add on were som hand written notes on the map with some "extras" such as good places for ice cream and off the track sights.

Accommodations were excellent and in the right places to enjoy the places we stayed.

I could go on much further but will simply state that this company is top notch, we would highly recommend their services, and thanks to them, our Iceland experience was a trip of a lifetime. Knowing nothing of Iceland and traveling with a 13-year-old, I contacted Nordic Visitor and asked them to help me.

Their recommendations were on-target and they selected tour agencies who were reliable, on time, courteous, helpful, and everything you need to feel okay about traveling in a foreign country. They arrange pickup at the airport who was there as stated and had all of my vouchers.

My itinerary was accurate and when there was a question, I just dialed Nordic Visitor or the tour agency. They have sound advice and follow up on their work. You still have to do your part (airline reservations, schedule your trip back to the airport) but if there is a problem, you have a friendly voice to talk to. Great guesthouse recommendation (good location, tour bus pickup right outside). Thanks to Nordic Visitor, Iceland was a wonderful place for a 5 day break. Nordic visitor provided an absolutely outstanding service, with agreed content, care hire, transfers, hotels, road maps marked up with great places to stop and even a mobile phone in case of problems.

That's because the Army football team does not go into its 3 p. ET game at Lincoln Financial Field in Philadelphia with the great weight of a long losing streak hanging over its head. The game will be televised by CBS. Army (8-3) ended its 14-game losing streak to Navy (6-5) a year ago with a 21-17 triumph, and it will try to reverse the momentum in the series by turning that victory into a two-game winning streak.

Army has not had a winning streak in the series since taking five games in a row from 1992 through 1996. The Black Knights trail 60-50-7 in the all-time series between these two service academies. These teams are mirror images of each other, as both academies run the option attack and are going to run the ball on most plays. Army leads the nation in running with 4.

The Black Knights also rank fourth in time of possession. Navy also uses the run as its primary weapon and has gained 3,822 yards this season. Middie quarterback Zach Abey is more likely to put the ball in the air than Army signal-caller Ahmad Bradshaw. Bradshaw threw just 39 passes this season, completing 12 of them for 259 yards with one touchdown and two interceptions.

However, he ran for 1,472 yards while averaging 7. Running back Darnell Woolfolk is a key contributor for Army with 668 yards and 11 touchdowns. Kell Walker and Andy Davidson have both rushed for more than 500 yards while combining for 10 touchdowns.

Abey has completed 30 of 70 passes for 803 yards, and he has seven TD passes along with seven interceptions.
