Dec

Yeah, lack of funds is my major setback at the moment! Final parts needed to finish off the mechanical end of things are: 1) 100mm driveshaft flanges + cable shift mech for the 02J 2) Lightweight flywheel 3) Intercooler piping 4) Oil cooler 5) Water injection kit 6) BMC cda 7) New complete front poly bush kit, and rear beam bushings 8 ) Exhaust downpipe Still quite an expensive list, even after the £1000's already spent on the car! :roll: And then to finish things off, a full leather retrim and a quick trip to the bodyshop to tidy ip a few little stonechips etc!

Cheers!...Saw you were getting some good work done on yours too! So figured I had better get my act together and try to have this can on the road (in some form at least) by the summer! :lol:

:roll:

Woohoo!.....Megasquirt II kit completely built and running perfectly on the simulator! :D And bought myslef the new Hybrid turbo, wastegate, FMIC, and all the fitting for the turbo this morning! Thats almost all the main components now bought! :turn-l:

Yup...or Duck tape did quite a good job removing them after I kicked the windscreen out of the rocco to put a new one in!

After conquering the higest road in Europe! Quick trip (or two) around the Monaco track! And coming down the Col De Turini Times like these, I wish I hadn't sold it now! :roll: :cry:

:lol: I thought the insurance was very high for what the car was!....quoted £750 compared to £360 for the Corrado with all the mods decalred :shock: :? I'm sure it was just some weird insurance company glitch, so check out some prices for yourself. But a few places were quoting me silly prices, so I just took the boring route and bought a diesel :roll: Mine was a 1.6Gt with a weber carb fitted, and it was great fun to drive! Ridiculously nippy little car! Very light, and handling was excellent once lowered and on decent shocks! Made the Corrado feel like a big heavy tank of a car in comparrison :shock: Thing to watch out for is the brakes! They're not up to much when new apparently, so only get worse with age! I replaced all the pads/shoes disks and cylinders etc just to be sure. :wink:

Only prob with rust on my old rocco was on the inner sills just beside where the rear beam is bolted on....nothing major though. Nice basic car, so easy to work on yourself..and the parts are all very cheap compared to C prices! I picked up a cheap on with no tax or MOT on it of Ebay for £50...spent the next few months rebuilding a fair bit of it at a cost of about £850 :oops: Then took it for a 2500 mile rally trip around Europe with pretty much nothing going wrong with it the entire time I was driving it! Great little car! Only sold it as I could afford to buy, service tax and insure a 1.9TDi for the cost of insuring the Rocco alone!!!...so I really couldn't justify it anymore :cry:

Actually saw that one on tv the other day (but not on that vid)......guy actually gets up straight away and runs away after doing about three cartwheels in the air! :shock: :shock:

lol......well I wasn't looking too closely...and deffo wasn't going back to look at it again!

Well I stoped watching it after the bit where the guy literally exploded after being hit by what looks like an Indycar!..and that was only 30 secs in! So be warned!! :(

:pale: :shock:

easiest way to get them off is to push the top of the hook inwards towards the pillar and get a flathead screwdriver in the gap at the bottom and twist it as you push, to lever the bottom outwards! Once you have removed them once and know how they come off, it's a 5 sec job :wink:

:lol: :lol: :lol: ...just noticed that too!!....God knows how that got there!!

Finally after almost a month messing around with Parcelforce, trying to get them to deliver a package properly the Megasquirt kit has arrived!! :D Megasquirt II ECU, V3 board, relay and stimulator boards! Plenty of assembly work there to keep me amused for weeks to come! I'll be ordering the Meagaview input/viewing screen once I have this lot assembled and tested!

http://www.vwspares.co.uk/corrado_clutch.php Best value I've found is AVS! £87 + vat for a Sachs 16v clutch kit with release bearings etc included and you get free delivery OR...go for a Vr6 upgrade Sachs clutch kit for £75 + vat :wink:

You sure thats not a plug for a cd changer? I've never seen any plug like that for a headunit itself Standard ISO plug(s) looks like this: It's common enough for headunits to require an adaptor cable to fit them into standard ISO wiring. But I've never seen a headunit plug that looks quite so different from the standard ISO plugs as yours!

Megasquirt II V3 Ecu and megaview controller ECU/controller kit!....unfort currently being held up in customs, so wont hav eit foe Xmas day! :cry:

Nah, the current one being used is the High Performance Computing Facility owned by Cambridge/Cranfield Universities! :wink: The clusters we use in here are basically a bunch of stripped down high speed PC's designed to run jobs in parallel......they are actually far quicker than the 'proper' big machines at small cfd jobs...as the big machines tend to almost choke themselves and never get up to their full speed on small simulations! :roll:

Yup, might get caught too!....nobody will notice 4 little processors doing something random! A few friends of mine that I did my masters with, work for Mclaren and Red Bull F1 now...not sure exactly what sort of computers they use for their cfd work though. The in house computers we use are only really used for 2D work...for the big 3D jobs we have remote access to the computers at the national supercomputer centre!....no idea what processors are in there either..but they are pretty d&rn quick!! :shock: :shock: :shock:

The machine its currently running on is a 56 processor (xenon) cluster. I don't exactly want to take the P*ss and take up the entire machine for something like this though...so it's only currently running on 4 of those processors. Problem isn't how long it takes to run each simulation, it's how many times you have to tweak each of those simulations and re-run them to get a good result! We use Fortran as all the commercial packages essentially only model the flow features, they don't truly calculate them. We have a 6th order accurate DNS Fortran based code (pretty much as accurate as available anywhere) for measuring nanoscopic flow features that the likes of StarCD, Fluent etc simply wont even know exist! It can only be used for tiny sections of a model though due to its high accuracy!

yeah, the road surface is set to be moving at 30m/s immediately below the car. The cfd package is pretty good at pretty basic models like this. Unfortunately it would take a long time to do a decent 3d cfd model on a shape even as basic as this car model. The grid I've used is too coarse (you can see how coarse it it by looking at the boundary layer around the car) and to reduce computational time, the viscous model I used is also pretty simple. It's not accurate enough to correctly predict the lift/or drag on a Corrado, but it's good enough to basically show what the airflow is doing as it passes over a car shaped body! As I said, if anyone happens to have a proper CAD model of a C, I could do a full test on it!.....it would probably take about a month to get decent results though! 8)

And a side profile basically showing the speed of the airflow over the car. Apologies for the dodgy Corrado model :oops: That big red region above the roof is accelerated, low pressure flow which causes your lift. The flow under the car is also accelerated, lowering the pressure beneath the car, but not to the same extent as the upper side. Once I let the sims finish running, I can make a quick change and put the spoiler in more of an 'up' position and see what happens! Or maybe even get back to the orig question and lower it a bit!....I'd need a far better model and grid to really determine any drag reductions tho. (assuming I don't have any real work to be doing) :roll: :roll:

Well here's a partially converged solution on a pretty rough grid...so not exactly super accurate. But good enough to see what the flow is doing. Shows pressure coefficient (red = high pressure, green/blue = low pressure), looking from above the front of the 'car' :lol: at just under 70mph You can see the high pressure at the front of the car and the lower side of the windscreen (drag), and the lower pressure green/blue regions as the flow accelerates over the bonnet and roof of the car (lift). And if you look at the back, positive red region of pressure acting on the upper surface at the rear windscreen/spoiler area. Which means there is a negative lift/downforce/pressure pushing downwards on that area!

We use Fortran for the most accurate simulations that the expensive software cant deal with! Much more efficient and generally better, but takes an age to set-up properly..and our code is useless for modeling large things like a whole car!
