bananawhip 0 Posted June 23, 2009 BORING BIT :sleeping: I've just been thinking that normally the minimum power gain you notice (depending on what you start with) is about 10bhp in real world situations, got me thinking that on a power to weight ratio how much weight saved has the same impact as 10 extra ponies...here's what I came up with... Standard VR6 - 190bhp - 1240kg - power to weight 153bhp/pt Standard VR6 with an extra 10bhp - 200bhp - 1240kg - power to weight 161bhp/pt Standard VR6 with a 60kg weight loss - 190bhp - 1180kg - power to weight 161bhp/pt So 60kg off has the same impact as around 10bhp gained, I know it's not a strict rule as a heavy powerful car will annihilate a light underpowered one once it gets up to speed but it's worth thinking about. It obviously has a positive impact on handling, braking, fuel economy :camp: and general wear and tear on the car when it's got less weight to carry about. FUN BIT :clap: Real weight saving is expensive and normally costs far more then just upping the power but lets club together and see what we can come up with to save a bit of weight on the cheap, obviously whilst keeping the car as functional and OEM as possible. Today I swopped my space saver and crappy jack for a can of tyreweld - weighed it, 8.5kg saving! Not a bad start and thats not even a full size spare Other stuff I've done in the past, £40 Decat pipe-saved about 5kgish and add's a bit of power, win win Plastic rocker cover, saves about 1kg and keeps engine temp down, free swop from a late Golf owner usually Neuspeed pullies, expensive I know but save 3kg of rotational mass and adds 5bhp, again win win but at a cost Anymore suggestions to help reach my golden goal of 60kg, Carbon canister deletion etc Quote Share this post Link to post Share on other sites

Dec 1 Posted June 23, 2009 The major one I noticed it the weight of leather vs fabric seats! Leather weighs an absolute ton in comparison! (sorry, don't have any actual weights for either though) Quote Share this post Link to post Share on other sites
mattnorgrove 0 Posted June 23, 2009 Always run at 1/2 tank maximum fuel. Petrol weighs 2.72 kg per gallon, so a late model 15 gallon tank would hold, when full, 40.8kg of fuel. Ergo, at half full you've lost 20.4kg! More than i thought it'd be to be honest! Quote Share this post Link to post Share on other sites
bananawhip 0 Posted June 23, 2009 remove abs pump stopping is for losers lol Not entirely sure the old bill would understand my quest when I smash into my 3rd bus stop in a week :) i never use my window washes so thats always empty Thought that was just me, I fill mine up using 1 trip with a 500ml coke bottle, not exactly going to crash and die if it runs out Always run at 1/2 tank maximum fuel. Petrol weighs 2.72 kg per gallon, so a late model 15 gallon tank would hold, when full, 40.8kg of fuel. Ergo, at half full you've lost 20.4kg! I do this too, never knew it weighed that much though! Very accurate and definitely something to keep in mind As for the leather :clap: yippee I now have an excuse to keep my fabric seats, sound money saving advice right there Quote Share this post Link to post Share on other sites

The_Dude 0 Posted June 23, 2009 Sunroof? Would a glass one weigh less? You could also remove the motor. Also remove all headlining, doorcards and trim. Quote Share this post Link to post Share on other sites

Guest Posted June 23, 2009 Errrm, don't take this personally if I'm just about to put my foot in it big time (and I don't mean to upset any C owners....) but.... go on a diet? I'm sure many of us could loose a few kgs without looking anorexic Quote Share this post Link to post Share on other sites
Sonicriot13 0 Posted June 23, 2009 I'm sure many of us could loose a few kgs without looking anorexic Not me! :lol: I'm underweight as it is.... If you have an early bonnet change it for a later one. The early ones seem way heavier! Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted June 23, 2009 Errrm, don't take this personally if I'm just about to put my foot in it big time (and I don't mean to upset any C owners....) but.... go on a diet? I'm sure many of us could loose a few kgs without looking anorexic Aye i could do with losing a stone. What about ICE? lose the stereo speakers, any subs or amps. Depends how much you like your music whilst you drive. I suppose if it was a G60 you'd need something to drown the droning noise out, but you have your own music under the bonnet with a VR - :lol: just to stir it Quote Share this post Link to post Share on other sites
The_Dude 0 Posted June 23, 2009 Lets not descend into another G60/VR debate please. :D And I could do with gaining a stone or two... Quote Share this post Link to post Share on other sites

bananawhip 0 Posted June 23, 2009 I'm sure many of us could loose a few kgs without looking anorexic Ha, that is completely fair enough, easier still though just lose any overweight friends you have due to "motorsport regulations", no more wasted hot laps with big passengers :) Like the idea of the Spal and equivalent fans though with the recent group buys going on. Any idea on the difference in weight between OEM and say a 11/9" with lasercut bracket set-up? Remember this is supposed to be OEM too boys and girls so those more off-key suggestions may not be acted upon. I'm not chopping my roof off, binning the spolier, fitting space savers all round, dropping in a hiyabusa engine or any such like malarky before it gets suggested, going on a diet though is on my to-do list :) Quote Share this post Link to post Share on other sites

Jay2 0 Posted June 23, 2009 Have stripped out the back of my C previously, as was thinking about 'track car' look, rear seats, spare tyre, ICE, parcel shelf, looked great. :D Stood back to admire the lighter C and noticed it was more like a drag car! :shock: Just chucking stuff out also needs to be levelled up or your suspension juggled with otherwise you end up with your rear end skywards. :camp: Quote Share this post Link to post Share on other sites
