I'm thinking of turning mine into a HSV Coupe 4/Monaro hybrid. What do you think? www.youtube.com/watch?v=5OKz3pJJPvg

Is it possible?

Definately possible, as the Coupe4 started out as a Monaro anyway. The C4 is quite a bit heavier than the 'ro, has a wider track (hence the added wider wheel arch thingys). If you sourced the same bits HSV used to mod the 'ro to C4 then you will poss find that you will have a big problem due to your current BHP. When the C4 was produced, the same model HSV's were 285Kw (about 350BHP) but the C4's engine had to be detuned to 270Kw, I believe because the 4x4 transmissions, gearboxes, axles, etc were not up to the task for higher power.

Anything is possible with enough money.


But it also makes sense to build a setup with usable power delivery where possible.
Good suspension, proper tyres and an engine combo that makes the power easy to control is always a good thing.

Id speak to Harry about just the cost for the bodykit before you look at the mechanicals mate, just that made me wince!

You are probably right. Also, didn't realise it was an auto and I doubt it's possible to transfer power to the front wheels with an M6 gearbox.

If it was a simple case of swapping parts then maybe, but the car was never designed for 4wd at it all looks like a bit of a bodge now I've done some research.

I'll get RL traction control fitted in the new year. Mark says you can set it up to control boost on the blower using the bypass valve which would be handy in the first 2 gears.

Cheers mate. Yours finished finished yet or still being developed?

Looking forward to next year and getting on the strip. Happy new year everyone!

Jez's approach is the best if you don't mind hacking the car around. The RLTC will help make the car drivable, but cant actually increase traction.

Nobody so far has been able to prove the relationship between tyre width and grip off the line. Wider tyres provide better lateral grip and it is argued that narrower tyres provide better traction.

Even Jez has suggested in previous posts his new, wider tyres make sod all difference.

I think power delivery, ideally lowish torque and tyre compound play a bigger part so RL is the way to go for me.

i would say heat and thick tyres that hold heat would play a big part as well

You need to look at the tyre contact patch, compound, wall stiffness. I still think Jez is on the right path.

Eh?

I`d say that to be .05 sec behind Gareth at TR begs to differ mate

More development, need to work on the bottom half of the speed range so the engines coming out and going to Peters for some work on his engine dyno

Common sense will clearly tell you more rubber on the ground will offer more traction. Other things can of course affect this...ie silly low profiles may not offer as much traction off the line as a larger sidewall tyre. But thats a different matter.


Just fit a pair of space savers to the rear for a demonstration.
