Sorry could you just clarify that point. Do you mean the whole car or just the position of the turbo? If it's just the turbo, then that must be some sort of fancy maths they teach down your way.

 

I edited the previous post a bit to clarify. C of G of the whole car.

 

i find that hard to believe myself,

just a query if you was to raise your centre of gravity by 1.5 inches would that theoretically be like removing 30-50 hp from your car?

where would you put the turbo if you were to relocate it? there is no room below its current position.

 

what is the koklen torque tube replacement? do you mean torsion bar tube? is it made from alloy? that could be a weight saver

 

The Kokeln rear suspension kit is shown here .
It is lighter, which helps, but if you look at where the monoball end is mounted, it also lowers the rear.
On the effects of CoG, width and grip you could read something like: Herb Adams, chassis engineering.

 

ok i get you now, your talking about the torsion bar. not the torque tube. are you allowed to pull out the torsion bars in your race series? i would still like to see how much you could lower the centre of gravity of your car and exactly how much of an effect it would make. is your car lowered at the moment? have you thought about the negative effects of the roll centre being lower then your centre of gravity? this is a very interesting topic

 

So this is only if you have rear coil overs correct? Does anyone know how much this is?

 

Torsion bars have allready been gone for a long time, suspension is free in our series. We left the torsion bar housing in, the current thought is replacing that too.

Weight distribution is a very interesting subject, OT in this thread though

 

if your talking about the kokeln torsion delete then yes you will need rear coil overs. which could be a good improvement. that could help with the 951's axel tramping issues. im not too sure how much the kokeln product is though.

 

Correct, rear coilovers are required. The Kokeln suspension is around $2500, ouch. And that is without the coilovers.

 

its your thread, so if you want to talk about it i am keen to listen. i believe the rear to too light in the 951 before removing more weight. its the front which i think needs weight reduction

wow, $2500 thats a lot of money for what you get. we arnt as lucky in our series, if torsion bars are there they must be retained.

 

Agree, weight reduction in the rear is not the prime target. Currently I am at 52% - 48% F/R.
I have looked into replacing the front with a tubular frame, and moving the engine 10 -15 cm back. Too expensive for my wallet.

 

now this is really getting interesting. how hard would it be to replace the front with tube frame? and at what point do you cut the front off? at the firewall or just past the strut towers? this would allow for turbocharger relocation into the right hand front guard.

 

It is not hard, it is just expensive. Total project to replace it from the firewall in the 10-15k€ region. The build actualy would be doable, it is the one of design that kills me. If there were 5 people to share that cost... Alas, no other weirdos around interested in this project.

So I will limit the front end change to cutting it before the shocks.

The idea is to build a car that can keep up with a GT3, without exceeding the HP/Weight limitation, and without the operating cost of a GT3.

With my current car I can keep up with the back of the field, on a 4 km track 6-7 sec. seperating me from the front. 10-15 cm wider, 3 cm lower, some add HP should put me in the middle of the field.

 

I found a video pertinent to that matter;
