Just before I buy...

There are a couple of Mac#1 Worx cars I have my eye on. I have pretty much made up my mind to actually get a Worx over all the other kits

If some of you would be so kind as to answer some questions:

1) Self centering - Is this a problem compared with other kits such as the MK which seems to suffer from it a lot?

2) Anti-Roll Bars - must be possible to fit these, but has anyone done it?

3) Inverted Gaz Shocks - read about them going a bit duff even though they have been re-valved. Any experiences?

4) Top Speed - I believe, with 13" wheels and a 3.21 freelander diff, you are looking at just over 130mph. Correct?

5) Steering rack - On the worx, does it come with a quick rack or merely a shortened Sierra rack?

6) Diff - Obviously the Freelander diff is open. Has anyone any experiences of an LSD fitted and whether it makes much improvement?

TIA

Hi

1. self centering is the same as an indy. It depends on how the individual car/ chassis came out of the jigs with the combination of wishbones currently fitted to the chassis.

2. Anti rollbars are available as custom made items from various suppliers and a few forum members.

3. Inverted dampers are a joke. They are NOT valved differently and anyone who thinks that valving them differently will make them work upside down is talking crap. The seals that are fitted simply are not good enough to do the job in that application and let air in which ends up where the adjuster is and results in NO DAMPING. Every Mac1 i have setup that has had them inverted has been the same. Simply bleed them out and refill with oil and fit them the correct way up. Or spend some serious money and get a set that will work in that application.

4. 5. 6. ill let some one with direct experience of the freelander set up comment on.

But yes the mac#1 is a better choice over the Indy as it has made some developments where the indy has not.

Cheers Matt

I thought the idea of a jig was that all individual cars/chassis came out identical?

The speed that your vehicle will reach is entirely dependent on :-

A, The max RPM that your power plant will produce

B, The power and torque that your power plant will produce at peak RPM

C, How brave you are at full Throttle

D, to a degree the size of tyres fitted as these also effect the gearing

E, How stable your vehicle will be at its top (theoretical) speed.



a 1.0l engine producing 80bhp at 10000rpm would be unlikely to get to 132mph, however, a 2.0l engine producing 200bhp at 10000 should get to 132mph.

I thought a jig was what HRH William, the Duke of Cambridge might be getting tonight.

Hence the phrase 'I'm jiggered'

Well, since a MAC#1 Worx has a ZX10R, gearing and RPM are known. Like I also said, 13" wheels and 3.21 diff.

I don't know the gearing on ZX10R's, so I was hoping someone could chime in.

BTW, you are incorrect with your bhp statement - 80bhp could reach 132mph because top speed is very much aerodynamically limited since drag increases at the square of speed.

Rest assured, the power the ZX10R has will be enough to propel the MAC to 130+, but the limiting factor will be the gearing.

my mac#1 zx10r will do 125mph flat out,thats with the freelander diff,but its not top speed you need,its how fast it will go round the corners,check my video.the white escort cosworth in front had 500bhp,hoppe this helps
