Fury Spyder Duratec build

because caterfield doesnt fit a flexible joint does not mean it is correct.

why most owners or sales-agents over here, retrofit, also on caterhams, such a flexible device, incl. most continental manufacturers of super-sevens?

anyway...its not my exhaust which may cause trouble..it was only an advice to make it better.

I don't think I have ever seen a flexible joint on a kit car exhaust. My, ceramic coated, 4-1 Powerspeed exhaust has a slip joint for the primaries into the collector.

Micha obviously has higher standards than are prevalent in the UK kit car industry or maybe it is a fix for a non-existent problem.

[micha]

other markets, other demands.....all modern (new) sevens over here come with a flexible joint and on more and more older kitcars such joints have been retrofitted.

from the engineering point of view its absolutely logic to do so. the reason why most manufacturers do not use such a joint are the costs.

Simply not true. If there was a wide-scale problem then the kit manufactures would have done something about it, Caterham (as an example) are not that price sensitivity that it would cause them to not fit a flexible joint if it was required.

I have to say, I have purchased one of the flexible sections with the intention of fitting into my Xflow system. I'm not sure if it will get fitted , but that is due to the limited straight line tube section available, not a doubt in the theory. I've experienced two failures at the manifold end on no 3 & 4 cylinders , and a complete 360 deg break at the front of the box which cost me a track day.

Probably more of an issue on the older engines, but I've seen many different arrangements of rubber bobbins, several slipper type solutions and a few flexible configurations.

I don't think cost is an issue, my flexi section cost me £22 a fraction of the cost of the exhaust system.

flexible joint could also be a slip in joint which is not clamped by a clip.

it must be something between the manifold and the sidepipe which could compensate the exhaust expansion when getting hot and also the engine movement.

22pound is "a lot" of money, when calculating a kit....nowadays people tend to buy always cheap...

e.g.: crap product is offered for 88,-pound
quality product is offered for 95,-pound

both supliers promise the same, everybody is aware that the cheaper one might be of a lower quality, but most people still decide for the cheaper one and complain afterwards...thats what i recognize more and more over here.

they want Mercedes quality for the price of a Fiat.

Micha,

I think I disagree with almost everything that you have said.
But, sometimes it is best to agreed to disagree.

Perhaps we can leave this thread to what it is, and that is a build thread.

[micha]

nobody has to agree with me, i can live with that.

back to the built!!!!

Another couple of weeks onward and the wiring is moving on well and we ahve been playing with the body work to get the tyres not to foul on the bodywork during steering lock and also to try and raise the bonnet to get nearer the minimum height requirement

Would not mind a bit of advice or comment on where the SVA/IVA man measures the "minimum" headlamp height from as even with raising the bonnet and with a 6 - 6.5" chassis height we are still not at the minimum height at the centre of the 7" lamps

One good thing - albeit rather annoying is that with the repositioning of the bonnet - it clears the Duratec and there is no need for the big hole that the original builder chopped into it - all it needs is the filler cap chopping down ala Caterham. It may only need a smallish blister type moulding to miss the air filter.



The alloy dash panel has been covered in Black leathercloth and the ETB instruments are in - looking more period now -only ruined by the Sierra switchgear.

It will be intersting to know what size wheels and tyres people are using as the 185/60/14's needed a fair bit chopped from the wheel arch before they cleared

I'm running 13" on the Phoenix and this appears to be quite common on Furys as well. Your car is looking good
