I should have been more clear. Too much catalyst dissipates with an acrid, almost vomit type odor, often accompanied by a pinkish color shift and/or haze. This is a different smell than the normal outgassing of formaldehyde. In my opinion, companies that use a diluted catalyst are just trying to sell more product. A gallon of catalyst at 3% lasts a lot longer than a gallon at 10%. 3% ratios are not difficult to measure with reasonable accuracy.
Crew weight. There is a wide range of crew weights that is competitive in the Viper 640. The average of all crew weights at the 2015 North Americans: 550 lbs. Crew weights ranged from a low of 490 (#10) to a high of 650 lbs.
This figure is known as a truckâs gross vehicle weight rating. Say a truck has a GVWR of 9,000 pounds and weighs 5,000 pounds. The 4,000-pound difference is the amount of cargo, passengers, and trailer tongue weight the truck is capable of carrying. Itâs this cargo capacity that the whole â-tonâ classification got started with.
