Volvo Weight Savings and Gains - example 240 model By Anthony Hyde

Weight - A 240 cabin floor pan has in some areas two separate layers of steel, then a glued down sheet of bituminous tar, then foam backed sound deadener mats, then carpet. The 'foam backed sound deadener mats' are very heavy, being easy to remove (or to refit). The bituminous tar, being glued down, is hard yakka to remove - Method - hot air gun and paint scraper.

1kg = 2.2 lbs OR 1 lb = 0.454 kg

Studies have shown a weight increase in the order of 100 lb or 45 kg will increase the time it takes to complete the 1/4 mile by about 1/10th of a second. (Quote by someone). Presume this applies to a weight decrease also, the aim of this discussion.
Depending on your determination, and what model 240 you start with, you can save the first 30 kg relatively easily, but the next 30 kg gets harder with either a comfort compromise, or increased $ expense as you try to save weight by using alternate lighter parts. For example, Volvo front seats are not light, but if you spend $500-700 each for two light race seats you'll save around 25 kg.

Weight removed by fitting newer model parts or modifying existing parts

Volvo Radiator plastic end tanks - shown inside is a hollow copper tube assembly that attaches to an auto trans. Newer genuine radiators use Al Alloy instead as its far lighter and cheaper to make. Most radiators have this ato trans cooling core, unless you specifically seek a manual gearbox version which doesn't have. The tube consists of two thin cylinders welded together with a large internal diameter for cooling water circulation to enable the heat transfer from one end to the other.

So if you have a manual transmission, save yourself extra weight of Cu 375 grams plus 40g for nuts, so 405g or about 1 pound.
