tzd problems

[the citroenman]

you can bar me off but dont say im wrong come to do it you all think that the tzd has a top end of 112 mph ????????????? you ar all wrong

[Tinkley]

Hi Citroenman, I do believe your speedo readings, but I have also explained why. Really pleased you have sorted your wobble out. I think there was reasonable agreement, it could be tyre related and people on this forum have helped you in that respect.

Please do not be upset, this forum is generally a great place for pooled knowledge and solutions or pointers to solutions to keep BXs' on the road. I think you would agree it has at least prompted you to review your tyre choice and get it sorted. Good luck and keep the BX on the road. I'm too far from you to pop over and check the car personally but maybe someone nearer may be able to give it a once over. Certainly at one of he Northern rallys I would think someone would like to check the speedo.

Reasons a TZD may show 132mph:

1. Wrong Gearbox / Speedo drive.
2. Undersized wheels / tyres (very!)
3. Hand of God (pushing you along)
4. Being caught in an F5 Tornado

Reasons a TZD won't actually DO 132mph (under it's own steam):

1. Reality...

To say any more on the speed would just be repeating myself and others, but nobody will be banned unless they become abusive, as happened on Facebook.

Well, all this challenging and throwing the gauntlet down etc has become rather tiresome. You haven't claimed your top speed so it's hard to be accurate on our feedback, which you seem to be asking for yet turning your nose up at.

Like Jay said, in a stock TZD turbo, your max at 4500 is 105 on the speedo. As has been said on your other 'come and look at my massive speed' post, the speed will read out by about 10mph.

You may have different gearing, although the rather obvious and brutal approach is to grind the lda pin to within an inch of its life and pack out the governor springs on the Bosch pump. That'll get your rpm up to a valve bouncing 6500 and impress everyone. Oh, I nearly forgot 100 bar boost on the turbo, that'll really kick arse.

O dear o dear o dear, if it makes you feel better that all other TZD owners, BX enthusiasts and the car manufacturer Citroen themselves are all wrong then so be it, you carry on dreaming my dear chap. I have to say though that even if it was possible why o why would you want to go to law breaking, licence losing speeds on a public highway in a flimsy lightweight machine with dodgy tyres

I'm getting desperate to see this bx in the flesh now.

[Mothman]

Cant see the need for speed in these old girls now. If you need to motor fast, go buy an Imprezza or something similar. BX turbo's are not sports cars nor were they ever meant to be and all ime sure all you will do in trying to get max speed out of it all the time is knacker the engine, preferably before you kill someone.
I just love driving my BXs, dont need to go mega fast in them, nothing to prove to anyone about them other than that they are class cars. If you disagree with my last comment you dont need to be driving one.
You should try driving an N/A diesel Mk 1 if you want a bit of class but i suspect you wouldnt like pottering about in an old motor!!

Sorry I am loosing the facts here. Is this a car that has already been modified or is this a discussion on why 130 mph plus is theoretically impossible? Two very different issues.

I am not sure I can see how an XUD can be tuned into a reliable unit to achieve such a performance but there is no doubt diesel technology can provide a unit to do the task now. Mods are always interesting even if one chooses not to take advantage of them.
In standard form I, frankly, find it hard to believe. However the proof of the pudding is in the eating and a trial against a sat nav will give a pretty accurate assessment of speed between two points.

[mat_fenwick]

You're only seeing half the story on this forum - this thread seems to be a continuation of one on Facebook where a speed of 132 mph was claimed from a standard TZD Turbo. Quite aside from not having enough power, it's beyond the governed rev limit of the engine so it was pointed out that this could not be possible!

Toys appear to have remained mostly inside of prams on this thread, so far at least...

[docchevron]

I've edited your phone number out of your post The Citroenman. Being a publicly viewable forum it's often not a good idea to publish personal details. All manner of nutters can get hold of it.

[Thread Bear]

Ah. Do not do fizzoggblobs.

However, I repeat that using a Sat Nav is a simple and accurate way to check the speedo readings. If this speedo is that far out then the wheel wobble at 80, which is bad enough, would be a cause of concern, as it is probably not then at 80 but within the legal speed limits. I would seriously want to know I had resolved that issue totally.

If the standard engine is capable of exceeding the spec parameters I would like to know how/why its been done.

[BX Bandit]

Sorry I am loosing the facts here. Is this a car that has already been modified.....

He won't say (thus far anyway) and quite frankly I don't particularly care what he's done to his car. The Peugeot forum pages are littered with tips and mods for Bosch pumps, they not hard to do and the car can appear stock unless you start taking the pump apart.

We all know a standard tzd turbo will not reach 130mph with out any assistance. It would of been much more appropriate had citman been open about his mods and how he did them to get his claimed max speed rather than throwing the gauntlet down in a rather holier than thou cloak and dagger way.

Dolls nearly out of pram......

Yay, Doc's about!

[Thread Bear]

So more of a pissing competition then. Well that's OK because its a double ended event, as it were. We can do his preferred road and then mine once a car is sorted out. Funny how the challenge normally fads when the details of the route and rules are found out. What counts is not outright speed but a to b pace. That requires a balanced package, a much more time consuming task than point and squirt. We are talking therefore of a well preped BX that can take on a Gti. Can be done.

[MULLEY]

An 8 valve Gti can't do 132 mph, & thats got 125bhp, so how is a diesel with 90bhp going to manage that speed, erm it won't.
