Give me a shout if you want your supercharged engine mapped

Will do mate! Won't be for a while yet as me and 'er indoors' are having our 2nd child in June (££££ )

Whereabouts are you? I'm moving near Reading next month for 18 month's posting so am losing all my workshop facilities i had here in Colchester That's why I had a sudden mad rush to get the car finished

[saqmaster]

Romford area chap.. Makes no odds to me.. good luck with the baby

[jimmyesh]

Thanks - gonna need it!

[coddie]

absolute stunner, just spent a whole hour reading this post. cant wait to see a vid of her in action.

[jimmyesh]

Sorry couldn't resist "stretching her legs" again when some french sh*t appeared glued to my rear bumper when i was just trying to just mind my own business as usual!

Still not quite 6k rpm either

[garyhurn77]

very nice 140mph at 5,800 gotta love having 6 gears


you need to get it to brunters see what it'll do

[Rusey]

Those 'private' roads in Colchester are good aint they

Impressive

[jimmyesh]

[quote="Rusey"]Those 'private' roads in Colchester are good aint they

Yeah it would just be completely irresponsible and dangerous to go that fast on a public road - thank god for all those disused runways all over Colchester!

[heeman10]

Good to see! Mine was at an indicated 130rpm at about 5,300rpm tonight down the track, which means about 122mph. You git!

Yeah I reckon mine's really in the low 130's, rather than the 141 (don't forget the "1" ) as speedo's are ALWAYS optimistic I'm afraid

[Sphinx]

Took this pic tonight:


Had it up to 126 but had to slow down and didn't get a picture in time......the errrr......marshals were calling me in off the track.....yes, that's the right, the track.....

[jimmyesh]

it's not big and it's not clever!

[Sphinx]

Agreed. It's damn fun though!

[jimmyesh]

Hi all! Yeah as per title the "MANJ" has now done 1000 miles since I completed the transplant! I just love driving it so much

The only thing I've got to sort fitting my heated front screen (i'm getting too old and grumpy to keep de-frosting it ) and my rattly exhaust at idle-It's REALLY pissing me off

As you can see from the pics It's having to brave the elements for now and as soon as i get the bloody thing clean our fantasic weather makes sure it gets covered in s**t again!! - Bring on global warming!

There's a pic here of how the rear wheels sit now me and my friend, Mark have manufactured my special shortened rear beam with 20mm removed from each side, we made a jig at work (took ALL afternoon) so we are 100% sure we've not messed any geometry up. The beam is a MK5 fiesta one so the bolt spacings are spot-on for the focus RS rear hubs too.

Having some good reactions to the car out and about on the roads too, been stopped by other motorists/passers by asking me "what the hell has that got in it?! (or words to that effect)

Just bought some new sills for the old girl as she's approaching 13 years old now and I'm getting her re-sprayed in radiant red as soon as funds allow (I've gone and "re-produced" so baby stuff is costing me loads )

Hopefully the bodywork will be in immaculate condition for FITP in May, It's my first FITP and can't wait to meet up with all of you and see all your projects in the flesh too

[saqmaster]

Are you concerned about how the torsional rigidity has been affected by shortening the beam?

[jayrs]

cool, got any pics of the work being done on the beam or the beam before it was put back on?

and have ya got the messurment for that focus hub yet

[heeman10]

The Fiesta rear beam doesn't really do much in torsion

Jimmy - As cool as sticky-out-wheels look, it looks far more sensible now the wheels sit into the arches properly. The Manjdroid braves the snow! Damn you for getting it all tidy for the show. I start hating people around this time of year when they get theirs all prettified and I turn up with the same old tat I think I'll bring a special keying key with me to quell my jealousy :bonkers: It's unbelievable how the miles tot up, I'm closing in on 9,000 miles now, and it was only mapped in August 2005!!

[jimmyesh]

Saqmaster: No, The way it was made that is really not an issue!

We're not a bunch of chives who just managed to stumble across a MIG welder!

Mark has been a metalsmith for 20 years now and has undertaken plenty of projects far more daunting than this effort. As said before a Jig was specially made for this job. Only the hub-mounting faces of the beam were removed then re-fitted to conform to the required measurement and strengthening was added where required. Camber and toe angles are as they were before. This beam is stronger and more rigid than before if anything and I am very happy with it.

I appreciate that when someone does something a bit different that it will ALWAYS create debate, that's what forums are for after all!

I am glad that I haven't just followed the crowd and just bolted something on because someone else has said it's the ONLY way of doing it

Heeman PLEEEASE don't key my MANJ! (My missus will castrate me If i have to pay for TWO resprays!:lol: )

JayRS: That ISO container got moved to another camp while I was away on a course with the hubs still in it!! Really sorry mate!

[saqmaster]

Well, that's how beams work. If you reduce their length, they become stiffer.. Although, in all fairness, the later fiesta beams are considerably stiffer than the old mk3 one.. so you may well be on your way to balancing the car out

[saqmaster]

Oh really?

It's not called a 'twist beam' for nothing..

[heeman10]

Beams work that way, yes, but the way the Fiesta beam operates isn't a traditional torsional application, but either way, as you've pointed out, making it shorter will increase its stiffness as well as its torsional stiffness, so the modifications certainly won't have any negative effects

[jimmyesh]

Yeah hopefully mate! I wasn't having a dig before. I'm just stubborn in the fact that I LOVE my 8" wide cossie rims (even though my car tramlines like a Bic™ on them! ) and having the 280mm rear focus RS brakes and hubs, so the ONLY option open to me was to shorten the beam.

[saqmaster]

The balance on my Fiesta Si is outstanding.. you can steer it with the throttle into 4 wheel drifts if you really want..

Let's not start using petty rolling eyes now..this is a discussion, not a handbag war please!

@ @

Consider the "@" signs to be the mounting points on the chassis, and we are looking down on the car from above, with the wheels mounting at the tops of the two rear-pointing beam legs. If the left wheel were to be lifted up towards us, it would cause only a very small angular displacement in the horizontal beam (assuming this is the part we're discussing with reference to jimmy's shortening modification). The major force is in bending, with the right wheel effectively constrained by the weight of the car, and an upward force being applied at the left wheel. That is not a torsional load, it is a normal load without a moment.

[heeman10]

That little diagram worked out perfectly! I'm sure you understand how it was meant to look

We're getting the "grey matter" working now - better get a coffee!

[Si_Dave]

Just read your post fella, top work with the Manj! I love the 'engineering approach' you've taken to it. Using your 'noggin' instead of as you say just bolting on bits because people say they will work lol!

Just out of interest mate, can I just ask what exactly tram lining is? I'v got cossie wheels on my Si and was hoping I could benefit from your experience so I can understand the handling on mine lol!

Also, with regard to the shortened rear beam, exactly what effect does this have from a handling point of view. Does the car turn in a lot better now with the wider front track when compared with the rear track?

All I've done on the back is to bring the rear track back to "standard" as the focus RS rear hubs stick the wheels out 20mm on EACH side as opposed to normal drums and internal hubs - yeah I think it handles better now (well i WOULD say that! ) as the rear wheels aren't further out than the fronts as they were before. I think Fiesta RST's came with a slightly wider front track

Tramlining is where the car catches joins or other inperfections in the road and "follows" them (like a tram funnily enough), it is much more prevalent in lowered FWD cars running wide rims. Can make it a bit twitchy hammering down "private roads" at 140mph!

Thanks for the kind words

[Si_Dave]

Ah right thanks very much for confirming what tramlining is mate, i had a rough idea what it might be becuase my car does exactly what you have described. Therefore as my wheels are spaced out 4mm all round, I will be takingt he spacers out of the rear and halfing them on the front. Will see if this reduces the tramlining effects.

I will also see if it turns in better then too lol!

On a side note while I am hear, just out of interest mate, are you running any rake on your Fiesta. In the sense of running the rear ride height slightly higher than the front to try and move imporve turn in? If so, roughly how much? Not sure how much is needed on a front engined car really???

Thanks for the help fella, appreciate that. If I have got it wrong with the rake then please point me int he right direction.

Cheers buddy,
Dave

The hubs were in an ISO container which I was stashing some random car parts in at work and while I was away on a course it got taken away I'm pissed off mate as I was gonna sell them - oh well the missus can do without any valentines gifts!

No pics of the work sorry mate, I'm on leave for another week yet (Full pay at the taxpayer's expense ) and I've already booked out of that unit so I'm trying to stay away from them or they'll have me over the coals for all the military jobs I didn't finish because I was too busy tinkering with the "MANJ"

I do have a very slight bit of rake dialled in but haven't got any exact measurements to hand sorry. My AVO coilovers are height-adjusted mainly for cosmetic reasons so I have kept the car pretty level, I might raise the arse up before I try any 1/4 mile shennanigans- I need all the help I can get against the Turbo boys!

I know that bloke (paul ripley i think...) ran a 4.8 sec 0-60 some years back in a red Fiesta RST that had the back end up in the air a bit so it does make sense as it puts more weight over the front therefore aiding traction

I prefer my car to look more level for day-to-day driving as I dont want it too sit like a '70's Dodge Charger

[jayrs]

shame about the bits though

[heeman10]

Stops it squatting too badly, taking weight off the front end too I found a major improvement in traction by winding the damping right up on the rears and softening the front end right up, so with some semi-decent tyres instead of the Yokohama A539 pap I'm STILL rolling on, that, twinned with low tyre pressures should transform the traction. As you say, they look far better levelled out
