Correct.
The AX GT cam is a tad peakier. Not alot in it, but the inlet valver stays open a touch longer, and the exhaust timing is a little later in the stroke. Not earthshattering stuff on it's own, but with the proper inlet manifold, and the twin choke it all adds up.

As for sticking a K&N on as is, like Kitch aid but in plainer english, muah ha ha ha ha ha ha ha ha ha ha ha ha!

It'll make it worse, and it'll sound like a wet fart.

Cartman, have you tried GSF for exhaust bits? They be not alot.

the following number plates are available at dvla for £390 all in:

C17 TGE

and

C17 BXC

a bargain methinks :idea:
I can think of about 1023 better things to spend as near as makes no difference £400 on (like an AX GT carb, manifold, head, rebuild, rear arm bearings etc)! But then I'm not someone who thinks paying for a funny plate is a worthwhile thing to do.

Plus, it really should have a 14 in there not a 17.

I agree. My first BX was the 14 and truth be told, if I didn't have the valver, or the estate, or a love for GT's.....I'd definately build a 14 with a tweaked engine using only OE parts from other TU engined cars. Aim for a reliable and frugal 90bhp. It wouldn't be hard either, and you'd have a car as powerful as a 16, lighter than a 16 and cheaper to tax than a 16. And cooler 8)

Wouldn't go mad though, prolly a set of alloys from something midrange in the Citroen stable, or GTi ones. Interior from....well has to be a Hurricane if we're talking about this particular 14. Valver seats would be trying too hard somehow, the Hurricane ones are a decent upgrade, but understated with it. Then a black dash/carpet combo.

In fact I'd dress it up just like a Hurricane, only with the 14 badges still on.

Hmmm....theres potential for an awesome project there.

kitch my friend,

as you posted just there, is pretty much precisely what i have planned for my trusty steed. it is a tidy car and a good base for a worthwhile and rewarding project. 8)

already, even as it is, i think the 14 is as nippy as the 16, although perhaps through rose tinted glases.

either way, its a car which needs subtle o.e improvement and fettling. in fact, sir bandit has sorted me a hurricane interior and pretty much complete black dash, to be done soon.

the only thing i really want is the hurricane pinstripe, any idea if this is still available at all? even through main stealers?

doc has already pledged to assist if he can, kitch, could you by any chance pass those bits you have to sir doc?

many thanks to all

chris

I've fitted a k&n panel filter to the existing set-up on my txd. Quite happy with it, made a small difference in performance but my main reason for purchase was that its more environmentally friendly, in just having to clean it now & again rather than binning loads of paper filters when they get mucky.

Yeah no problem, I'll issue him with the GT cylinder head on the weekend. Project sounds good, although I'd peronally give the strip a miss....it'll save hassle trying to sort one, plus you're replicating a Hurricane, not making an exact copy.

Hurricanes also have the number plate panel part of the tailgate finished in satin black. If it were mine, I'd make sure i had green tint rear lamps and leave it painted green, but thats just me.

Having driven 14's and 16's, I'd agree the 14 feels every bit as eager as a 16. The 14 is a bit more frantic, the 16 feels more lazy. Whether the figures would support it remains to be seen, but with the AX GT setup, plus an AX GT gearbox (perhaps with a BX 14 5th cog for betetr cruising....AX GT's are doing 4000rpm @ 70mph!) it'll be good fun without breaking the bank, and most importantly it'll be reliable.

And what cleaning products do you use? And do you cover the filter in filter oil afterwards?

Cold water only & depending upon how dirty it is, a cleaning solution (i think its biodegradable) & yes there is an oil to re-lube it once cleaned (only talking of using a small amount in ml's).

You only have to do the above when the hoover cant keep it clean anymore. So over 100000 miles of usage i reckon its more friendly than the waste of all those paper filters.

So a small forest saved :lol:

I like K&N panel filters, and have fitted them in most of my cars over the years.

Not for the environment, I am just too lazy to change them every year.

kitch,

have been offered an ax gt carb and manifold off the owners club site. £35 all in inc postage.

just checking condition as we speak. if it needs a refurb is that a biggie?

Yeah £35's not bad, aslong as the seller can gurantee that it is in good working order. If it is, it won't need overhauling straight away.

You know when they're unhappy....you should be able to accelerate smoothly with your foot progressively pushing the pedal. Then, when you nearly hit the bottom it'll feel like the pedal has clicked, and the car should suddenly become much more frantic. This is the second choke opening, effectively doubling the air/fuel mixture being drawn into the engine (it's not actually doubling, but you get the idea)

If the carb wants overhauling, you'll either push your foot to the floor and it'll just keep doing what it was doing already. Or, it'll go mad when you floor it but won't pull smoothly through the rev band, dropping and missing all over the place.

I believe it's not too hard a job to undertake, and like Mike said if you get a K&N you get a new needle to fit too, to keep the air/fuel mix right.

But if that carb setup is working well, it'll be the best £35 you spend on the car. Just make sure to ask the seller if it comes with the black plastic trunking from the airbox to the carb, as your BX won't fit.

Also remember you're going to need all the gaskets and seals to fit it. And lastly IIRC the BX manifold isn't cooled, so in order to get this fixed you just need to get a couple of T-piece sections and plumb into the heater hoses....no big deal, as everything is easy to reach on a TU in a BX engine bay. 8)

kitch,

the chap says it was ok 3 months ago on his track car, but has since been taken off, he also says he has a pipercross induction kit for £20.

i thought an induction kit was only for injected engines.

but hey i might be mis-informed :!:

Generally an induction kit is only for injected ones yeah, seems a bit odd. It's probably just terminology and he means a bolt-on filter. I'd avoid that personally, carb and inlet are fine. He probably doesn't have the black intake thing though, if he's got a filter bolted on but you never know.

A cold air feed is always a good idea, as cold air is more dense than warm air. The warm feed is used to prevent carb icing.

More air in = more power out.

With a Hurricane interior and instruments, you would get a
BX14 GT.

As Kitch says, low road tax, decent economy and decent performance.
