Thread: Weight Reduction INFO

  1. #21
    Always thought the standard 3200 wheels were heavy - a nice set of magnesium or carbon fibre would be nice!
    An interesting thread thanks.

    I've got the forgestar F14 wheels (from Formula Dynamics) and they are supposed to be lighter than the originals, must weight my original BBS wheels for comparison.
    Also having larger diameter wheels can cost weight, probably an additional 10Kg in total going from 18"(32/42) to 19"(GS).
    Aluminium belled brake discs will have a few Kg's too.

    I can't get over the complete lack off weight savings in the design of this car, especially the interior. The steel trim on the doors, the center console bezel it's built more like a tank than a sports car; yes I know it's a touring car, but weight is the only thing stopping it from competing as a true sports car. I'd bet you could strip close to 500lbs off the car with little effort and minimal loss of functionality.

    Exactly,lots of weight everywhere but it's for comfort and part of the prestige and appeal of the car , just make sure if you take anything off do it slowly they have so many hidden clips and bolts it's outrageous so take your time as not to break cause you'll be reinstalling one day .Only thing stopping me going full out on a nude diet is this car doubles as my second family car now that's another thing that's so cool about owning a Maserati you can throw a couple of babies in the back and the hooks are there for the seats too lol, from memory I don't think the back seats weighed too much maybe bottom half 5kg top 10kg, I need to get off my *** and unravel my crate I got all the interior air tight packed away in one so I can grow the list of weighted parts on page one, will get some wheel and tyre weights up too

    Hey guys been a while but can someone please help
    Me find out the weight of the oem front and back wheel
    And tyres for the 3200gt? Mine came with aftermarket bbs and I’m really interested in finding out exactly where I’m at with reduction I’m over 100kg atm easy and have all seats and nothing suspicious other than race seats from appearance wise ,need those wheel and tyres figures please 

    Thanks very much Mike much appreciated, can easily shave 10-15kg off the total of that with other wheels my Bbs
    19x10 295/30/19 continental( 23.5kg), 19x8.5 245/35/19 pirelli (22.6kg)
    My 18inch Bola wheels are lighter again just need to weigh them when I get time

    Some years ago (before this forum was established) 'MaseratiForum.co.uk' carried a long thread about weight reduction on the 3200, and there was spirited debate about the merits of sprung/unsprung weight and what could be achieved for either. IIRC, the upshot was that unless you get really radical you're not going to achieve much improvement either in performance or handling, though there's obviously no harm in trying. Sadly, the old forum can no longer be accessed.

    There was also an unconfirmed story that 3200 engines were detuned (I think by altering the valve timing) to avoid embarrassing Ferrari performance figures, and some folk claimed significant improvements on their 3200's by having the timing checked/corrected; whether the evidence stacks up is anyone's guess, but it is food for thought. However, Voicey (AV Engineering – forum sponsor) emphasises the importance of correct valve clearance for the 3200 so it might be worth a thought:

    There is an undeniable benefit to even a small decrease in vehicle weight, particularly in rotating parts of the drive train prior to the gearbox. The reason for this is gear ratios. A gear ratio is basically a lever increasing the applied torque. A good example of this is using a long bar to undo a tight bolt. The long bar multiplies the torque, making it easier to undo the bolt it also means the end of the bar has to move further to give the same number of rotations of that same bolt.

    If you think that in first gear the engine turns around four times for one turn of the road wheel compared to in top gear where it is more like 1 to 1. This means that if you remove 10 kg of weight from the flywheel (or another part of the engine internals) the engine actually sees this as a reduction of 40 kg because of the gearing effect.

    To put it another way, if first gear has an overall ration of 4 to 1, this means that the effective mass of a 2000 kg car would be 500 kg. Because they are located before the gearbox the effective mass of the engine internal components remains the same regardless of the gear. So for a 10kg reduction in the engine rotating mass equates to 2% of the effective vehicle mass (or 40 kg) in first gear, but in top gear (say 1 to 1) the reduction of 10 kg is 0.05% of the vehicle mass (due to there being no gearing effect) and so remains 10 kg. Of course taking the seats out of a car is cheaper than having the flywheel machined so you pay your money and take your choice. This does at least explain why race engines never idle well, they have paper thin flywheels to increase acceleration in the lower gears.
