had day off today so fixed my exhaust in morning and then this afternoon decided to try and find out whether xe corsa really does handle worse than lighter lump.
so got my mrs x16xe corsa and mine and did some various tests like hitting a roundabout at certain speeds and then timed myself roughly ova a quiet country lane etc and did lots of little tests.
i gotta say only thing i can notice is my mrs car is more stable under braking load, but the understeer i think is just the sheer TORQUE ur pushing through wheels, not that fact its a heavy lump. i hit a corner very hard in mrs car and got under steer with foot to floor in second, while observing speedo too i did same in my xe and with throttle down enough to accelerate as quick as mrs 1.6 round the same corner i got same amount of understeer, so i then took coner with my foot to the floor in second and thats when it got worse, so the acceleration and loss of control must be down to the torque.
obviously im gonna get ppl disagree here but this is my opinion and i spent over 3 hrs swopping and changing between my 2.0 and mrs 1.6, braking seems to be far stabler in mrs though which concerns me

nah, its simply the weight of the front of the car pushing you the other way to the corner, not the tourque. its sliding out from underneath, wheres a lighter engine wont do it as its more balanced, surely?????
i can take corners at the same speeds but if i pushed the car as a 1600 16v it would try and put me into a ditch

yeh but its not til u try and put full power down it slides
if u half accelerate, same as mrs 1.6 it does same and tim goin quick not 10mph lol

so, basically if you floor the 1600 flat out to say 50 and keep accelerating hard its the same as if you hold the xe at 50 and not accelerating hard?

no obviously the xe accelerates quicker than 1600 dont it so u dont need to open throttle fully on 2.0 to be goin as quick as 1.6

yeah, but that means that the force driveing the wheels isnt the same ie full throttle, so really, its not, well,i dunno, it doesnt really explain a great deal to me, lol, im un decided about it.

yeh it proves that flooring the 2.0 as u cant put power down to the road can u, but 1.6 u can with no trouble, so the 2.0 spins the wheels up creating understeer, but its the torque creating it not weight if u get it
though weight is having an affect but im saying ppl are confusing torquesteer with understeer, like i said only braking i found more stable in 1.6 which is better in my opinion to have more stable braking really

But if you learn to drive the car and dont spin the wheels round bends then you might see better improvments !!1 Its Obvious if you come round a bend and have no traction on the front wheels its going to slide out of the corner (Towards the kerb or ditch)!!! Unless of course your delibratly putting the car out of control? Which by the sounds of it your not

wheelspin doesnt dreate the understeer at all, thats all together different.
the understeer is caused by the weight over the front wheels trying to keep going straight on

Yeah but if hes flooring it in a powerfull car or Xe in the wet comming out of a rounderbout you will have limited control over the front wheels!!! and the car will loose traction on the front wheels and head towards the kerb!

Ofcourse wheelspin creates understeer! you go round a corner and boot it the car slides straight on instead of turning, which is understeer. You also get understeer when you enter a corner too fast and it goes straight on instead of gripping.

in a 2.0 corsa though i think ppl are fooled by power, they are flooring it everywhere and when jumping from small lump to xe ppl are gonna do this, but if u learn to modulate the throttle and NOT FLOOR IT all the time it is no way as bad ppl are making out.
my mrs has 1.6 corsa so i get to drive both very very regularly, and i was getting just as much understeer on my mrs 1.6 at certain speeds, but xe only got worse when ur flooring it meaning its not gripping, this to me ent understeer its loss of grip and u simply cant put power down to the road.
BUT WAS FUN EXPERIMENTING

i think you just wanted an excuse to go and have some fun
lately i have driven both a 2 litre corsa and my 1.6 and i can definately throw the 1.6 around easier than the 2.0
really depends on the suspension set-up though.
both are great fun. i love the way the 2.0 pulls hard from 2k revs.

all depends on suspension set up tbh
weightwise over the front wheels i didnt really notice muich difference between the 20xe and 14xe
It can take the corner just as well now as I did before its just now the corsa is faster hence you try and better yourself hence inducing understeer far easier.
Also I am intrigued to see how changing all my TCS's and bushes will make a diference now.

yeah thats what i meant fad ur ragging it more hence goin alot faster.
its mere fact u got that large gap in acceleration which is what ppl are saying is understeer, i think its torque through the wheels more

Also i got to say even though understeer is more evident i quite enjoy the challege of pushing the car to the limit and just controlling it. Just makes the drive to work that little bit more interesting
