Oh, just the 911s are rear engine then?

A noob question but when did Porsche's have mid engines?

Wow really sorry to hear this, I hope you get well soon and make it back in one piece!

Well, after initially wanting to do this back at Uni for my final year project but not being allowed to do it (because is wasn't "Academic" enough), only to then discover a nice seat in the attic of my brother's house a couple of years later when I started working at 3D Scanners UK, I thought that I'd give it another go and to use this seat as part of the racing simulator that I could build......fast forward 4 years and I've finally got round to actually doing it. So when I first started working at 3D Scanners UK, as a way to learn PolyWorks and to practice using different scanning systems, I thought I'd challenge myself by scanning this seat that I had found from my bothers attic so I could reverse engineer the seat. This was so that I could then import the seat into a CAD package like SolidWorks to design the frame around.....sadly that never happened and the seat has been sat in the corner of my room for the last 4 years. I was also originally going to buy a Fanatec steering wheel setup but I couldn't afford it at the time and then along came another car plus mods and real trackdays which meant that again, the project never took off. This is the raw scan data using a laser line scanner connected to an articulated arm. This is the data after it had been meshed to make what we call a polygonal model (a model made up of triangles or "polygons") And this is after many hours reverse engineering from a scan into a solid CAD model by creating what we call a curve network in a way that it creates 4x4 NURBS patches. However recently I purchased a Logitech G29 at a pretty low price and after being called out by my friend Darren who is a games designer for Codemasters on the new Dirt Rally game on the Dirt Rally Road Book blog, I thought it was time that I kicked started the project again. So after having scanned my seat, I then set out to scan the Logitech G29 peripherals. Now I initially started to umm and arh about just buying an off the shelf racing simulator but then it hit me, I've scanned all this stuff....why don't I scan the interior of my 86 so I can get the exact driving position I currently have rather than hope that these off the shelf racing simulators would offer something similar (plus the enjoyment of building one yourself). So I started to scan the interior of my car, aligned the scans of the Logitech G29 peripherals and the seat to the positions of my interior driving positions, dimensioned up the scans for their positions and angles and then exported all this out into SolidWorks. Within SolidWorks, I started design the racing simulator using aluminium extrusions and positioned everything in relation to the scans that I had imported. I also had some design criteria that I had to include such as being at a certain height due to the height of my TV and adjustable seat and table top for when I'm not racing. The design was changed to make construction a lil easier and to generalise some of the parts rather than having lots of unique parts. Not only that, since this is inspired by my 86, the pedals would need to be pointing in the right directions too i.e. hanging upside down rather than pointing up. After a couple of further minor design tweaks, I assembled the parts together along with modelled up brackets etc so I could easily generate a bill of materials of the required extrusion lengths and quantities, number of brackets, T nuts and bolts, then set out to get prices. Here you can see the overlap of the original interior scan of my 86 compared to the designed racing simulator that I hoped to build.

Seibon are only about double the price of OEM

Will definitely be keeping an eye out....still want a left hand drive drivers seat so I can stick on the passenger side to lift the seat up for rear passenger feet.

Plenty of 3D CAD packages out there to play with if you know where to look [emoji12] And they're usually not too difficult to pick up and learn, plenty of tutorials and videos about on YouTube and the likes.

Thanks all.....heated seats are a definite no no for me, even on a real car....my room is usually roasting anyways and I don't like the pissed ones self feeling

Congrats and welcome to the club!

51 inches about a meter away from the steering wheel....that big enough? [emoji14]

Being an ex Codemasters employee, this brings back memories and I've always loved the rally games, even if I would work on them day in day out, I'd still play them once the game was released. All that is behind me now but I still have friends in the company which are hyping the next DiRT Rally game (sadly missed the early access as it was just for PC and don't tend to game that much with my PC) and has been very successful thus far. The console version is due out soon and after I told my mate that I was planning on building a racing frame for my Logitech G29, which I picked up from Curry's at a very good price, he gave me a shout out on their DiRT Rally Road Book blog site, I decided to send him some pics of what I had done so far and this is what he's posted up: -------------------------------------------------------------------------- Remember last week, when Keith posted in the PS4 Gossip Thread about planning his custom built racing frame? Well, he’s pulled his metaphorical finger out and started work on his masterpiece. Building a custom frame isn’t unprecedented, but Keith has gone to incredible lengths to get his just right. He’s a member of the GT86 Drivers Club, but by day he spends his time scanning cars and producing 3D models. This put him in the perfect position to replicate the feeling of being behind the wheel of his own car: “I used a 3D scanning system (laser line scanner) and our software (PolyWorks) to scan the interior of my GT86, followed by scanning of the Logitech G29 peripherals. Once I had finished scanning, I then manually aligned, by eye, the scans of the G29 parts to their relative positions within my car. Once roughly aligned, I could then use PolyWorks to measure the mating faces and fixture holes so I could then export that information out into a CAD package called Solidworks. From there, I could then design the frame around these key locations using primarily 30x30mm aluminium extrusions.” How cool is that?! If you’re working on your own custom build, or if you just want to share your home setup with us, feel free to get at us in the usual places. ------------------------------------------------------------------------- Original - https://www.dirtgame.com/uk/blog/5470 I asked him to give the club a shout out and he did, what a legend. I've pretty much finished the design, just getting prices for parts etc which has been a bit of a mission, might end up sourcing the aluminium extrusions locally but then buy the brackets and what not from china as its a lot cheaper, the extrusion would be too but shipping is the killer really. Can't wait to get this made and to play DiRT!

Just to add to my setup now: This is now sat in the bedroom after I broke my bedroom/office chair......it's a rather nice replacement....shame it doesn't swivel when you're not racing

The aluminium extrusion was all brought from a company in Leicester who for a lil extra would cut all the bits to the correct lengths but the brackets from them would have been extortionate so I ended up ordering them from China which took a while but were mega cheap compared to the UK. The extrusion on the other hand would have been mega expensive from China primarily due to the weight and size of the stuff. Here are all the 30x30 extrusions that I brought all laid out. The various 30x30 and 30x60 brackets from China along with a boat load of cap screws and t nuts. Some interior L brackets that will need modifying so I can use them to help support the small plate for the steering to sit on, this plate can either lift up and be flush with the rest of the table for everyday/keyboard use or they can hold the plate at a set angle for the steering wheel to mount to and face in the correct direction to me. After a lot of modifying of brackets, the corner brackets all had extra bits sticking out of the flat faces (which you might just make out on the brackets to the right) to prevent the brackets from twisting but because I need to rotate most of these 90deg or whatever funny degrees I needed, I had to sand down these knobbly bits. Once all the components had arrived, I then eagerly start to put her together starting with the seat frame first. 80% of the seat complete Mock test of the seat mounting to the seat frame. Parts for the front frame all laid out on the floor. Sadly, due to my own incompetence, I took the dimensions of the brackets and extrusions from a different source which meant that some things arrived bigger than I originally anticipated, so I had to rejig some bits to fit together and luckily I was allowed to take a load of unwanted bolts from work that were long enough for the bigger parts. Part way through, I also modified the racing pedals by literally swapping the clutch and accelerator pedals around so when you flip the pedals upside down, they were in the correct order. Another issue I came across was when I had some 12mm thick MDF brought and cut from B&Q, the guy at B&Q missed out a panel of MDF that I the drawings for which was even handed to him.....he just ignored it or completely forgot....and because he had the drawings I forgot too so again, I had to rejig some of them too but it all eventually came together. The only thing that remains to be done is the arm rests which I have the pieces for and the foam but I just need some fabric and staples to put everything together. But I've been using it so far and it is glorious!!! Many people will not understand why, some will but think I'm crazy, but I'm sure there will be those who geek out at stuff like this either way, it's all about the journey. Being able to design something and actually create it is always a great feeling, it's just a bonus that it's a racing simulator that I use to play Project Cars and Dirt Rally with! Hope you enjoyed the story!!!

Well....I can confirm that Dirt Rally is awesome and bloody solid....it's taken me a while to get to grips with the handling but it's very challenging and even unforgiving with the likes of the challenge modes (daily challenge is one stage one try, weekly is 6 stages one try and the monthly is 24 stages one try) where you can get right to the end of say the monthly challenge of 24 stages and then write your car off just before the end and not finishing. One of the really cool things about the game though is when you've done a challenge, you can visit the dirt website https://www.dirtgame.com/telemetry/0 and actually watch either your run or other people's runs from a top down perspective. See when they were accelerating, braking and hand braking. What's cool about this is also the fact that it was a tool that was originally developed so the developers can monitor and check if people had been cheating at all, but then released how cool it was to visualise people's inputs for a top down replay that they made it an actual thing that people can use.

Congrats and glad you're enjoying it. Any head unit will be better than the OEM one but as for aerial, you can easily go stubby or shark fin. There are various shark fin ones around, the more expensive ones like the beatsonic ones are good because they go over the existing aerial base and connects to it where as I brought a very cheap one off ebay (about a tenner I think) but this removes the aerial completely and in order to have the aerial to work, you'll need to splice the existing connector to it which I haven't bothered as I don't listen to the radio at all.

Besides accelerating hard, had it occur most when letting off the gas at high revs and letting the car engine break

Sorry for the late response, I didn't actually get up until 11.....a very much needed long sleep! Hoped you all had fun!

Congrats! Regarding reversing camera, highly recommended, can't imagine having a car without one now, much better than the annoying sensors.

Nice numbers....anymore?

I want to try out a Cosworth charger, I know Will e-mailed Matt from Cosworth to see if people were allowed to test drive their demo car and the answer was no Not the way to go if you ask me, the only way to demo their kit is to do what Subota Boy did and find a dealership who happen to have one and is trying to sell the car.....sadly none near the midlands

Did this get sold in the end Zmithy?

I've had it and it'll come back on at some point....but will go off again on it's own at some point too. I recall seeing a slightly drop in power on the dyno but you don't actually feel it, the only really annoyance is that when it appears, you can't use cruise control at all. Got mine swapped out under warranty no problem.

Wow that is pretty massive....how stable is it? Did you see the white one at Japfest on the traders stand that was probably slightly bigger and mega wobbly.

Do you need to be worried about sucking up nasties on a new/relatively new car?

Is that why the Super Car Seige is no longer there? That is bloody outrageous.
