Title: 2.5 V6 X25XE engine and gearbox weights
Post by: markrnorton on 21 August 2012, 14:13:04

Chaps

I have done all my searches to no avail

Does anybody have accurate weights for the 2.5 v6 lump and the manual gearbox ?

trying to work out some spring rates for the car and need some decent figures

thanks

I found C25XE as 176 kgs (without ancillaries) .. so 180 kgs of prediction wont be wrong for spring rates..

Thanks CEM

36kgs for the gearbox seems a bit light though, i would have though it heavier.

compared to ar25 or ar30 yes.. they are light.. but if you carry them alone not that light ;D
 
when I first time carry ar25(me and someone) I thought its over 150 kgs ;D  but actually its around 80 kgs but you feel its  bloody heavy :o

please excuse my butting in but i consider that 80 kgs is rather heavy or was the last time i put 1.5+ cwt on my back! (for those of us old enough to remember old money !) good luck to cem and mind that Back.

Thanks for the replies guys

nice light gearbox then  :)

should help keep the total weight of the car down and maintain balance

the best advantage of manual is that your car is not applying half clutch while accelerating (till 80 kms/hr) ;D   :D

i think i understand what your saying, yes you are right. and in the kit car its important to get the power straight down.

i think my target gross weight of 650kgs for the car is achievable

yep.. personally I can recommend to use this T6 alum as much as possible
its an aluminium alloy with zinc,magnesium, copper, iron,chromium and titanium..
 
http://en.wikipedia.org/wiki/7075_aluminium_alloy (http://en.wikipedia.org/wiki/7075_aluminium_alloy) .
 
its strength is close to steel
 
density 2.8 gr/cm3 where as iron has 7.87 g/cm3
 
and price not that steep.. :y
 
ps: can be found in all useful size and shapes..
