Untier

just found a old email from someone, says his 951 with the v8 conversion running on the street with 1/2 tank of gas, truely weighs at 2910#. with out looking at some book? who actually has a weigh slip and how much does yours weigh with 1/2 tank? no flames just curious?

Untier

doesnt anyone have a weigh ticket?????

Untier

come on now guys, for as much as you flame on the v8 weight issue.. somebody must have a weight ticket. anybody got a match?

MAS

I think the problem is that most people here do *not* have V8 Porsche conversions... and so, could only guess at the correct weight(s) for re-engined cars.

sorry. i meant stock porsche car weights or even modified porsche weights. anything where someone has actually weighed their car and has verification. to compare to the 2910 of the v8 conversion.

MAS

OK, depending on the year, the n/a 944 weighs about 2750 lbs (give or take a few lbs). So 2910 is pretty good. But, aside from the engine swap... how stock is the rest of the V8 car? It may have been moddified in other ways too. The stock (early) 924's were quite a bit lighter... a little over 2300 lbs. Although the 924 Carrera GTR weighed under 2000 lbs and had 385 hp.

each book i read has a different weight, where did you get your weight from? hasnt anybody weighed their 944/951 on a scale. i would do mine but im tooo cheap!

adie

Sorry , mines race weight with many glass pannels, for what it's worth (not a lot probably) it weighs in at 2165 with me in it, full cage and fire system, add 26 lbs for Nos bottle and gas, I run about 1/2 tank gas, to ensure it doesn't run dry. perspex side and rear, normal glass front screen. Working lights and wipers. although these are next to be removed now it's in the 10's.

Untier

just to show how good the books are... i weighed my stock 88 944 na today.
it had my MT lunch cooler, work shoes, 2 new coleman folding chairs and 3 cds in the glove box. and less than 1/2 tank.
it weighed 2930 lbs, no ****, 2930 pounds. i have the ticket to prove it. this is a stock 944 na, after the V8 goes in i will weigh it again. FLAME ON! porsche purists.

MAS

I think that the later 944's (like an 88) were heavier than the earier ones.

Nah, I reacon the problem lies in the 3 Cd's, you should have taken at least 2 of them out first.

OK, when I read this suggestion, I was a bit skeptical, but supposedly it works.

If you measure the pressure in your tires in PSI, then measure the length and width footprint of each tire (in inches), you should be able to calculate the weight (in pounds) that each tire is bearing, and thus add up the weights and get a total vehicle weight.

For example, if I have 32PSI all around, and each of my tires has a footprint of 7" x 3", then each tire is bearing 672 pounds, for a total of 2688 pounds.

My car has 205's all around, which are about 8". At 32 PSI, the footprint would need to be 8" x 2.68" for my car to weigh in at 2750 pounds total.

Let me know if this is truly BS, I haven't actually tried it

don't tires have different elasticities that would affect it?
And also the type of rubber, soft, hard.

Ferd

Good in theory, but not in practice. Too many things (belts, cords, overlays) in a tire to screw this up. If you reduced the air in the tires, the footprint would reach a certain size and stay there. Might work with a beachball or a balloon, but not a tire.

Just remember, V8s rule, that duct tape is plenty heavy, don't use too much when you install your iron.
