    Re: Tarmac "GpA" rallycar build.

    well it's gotta have something to do with the fan. As darren, i'd have guessed at space but I couldn't say why? Unless your having a fan either side for super cooling....?

      Front mount fan and a stronger structure to mount a sump guard to?

        It is to do with cooling but not engine cooling...

        As the car will be fitted with a 2.0 litre engine, it needs to weigh a minimum of 1000kg due to the class rules in rallying (1400cc min is 840kg, 1600cc min is 920kg and 2000cc min is 1000kg). I reckon it will come in around 960kg fully built so will need to ballast the car by 40kg.

        The cars first event is going to be Rally Barbados 2015. The temperatures are stupidly hot, especially in a nomex fireproof racesuit..

        So I thought, why not run aircon in the new car. Its adds around 25kg to the build and will only be run on the road sections between stages but I reckon will make a huge difference to the experience having been there in stupidly hot conditions previously..

        So, a rallycar with aircon.. in a car that wasnt fitted with aircon.. Im up for the challenge!

          Re: Tarmac "GpA" rallycar build.

          Ste came over last night to weld some of the seams Id prepped...

          Engine bay, strut tops and bulkhead



          Drivers side inside car and tunnel



          Tunnel under car



          Wishbone mounts



          Im not going to get much done between now and next Monday due to work and roadrallying but will hopefully get the engine bay plating started next week and the rest of the already prepped seams. Booking the car in for its rollcage too so will have a date for that.

              Re: Tarmac "GpA" rallycar build.

              More weekly progress...

              Strengthening plates fitted to tie the chassis leg to strut top, the inner wing area behind the trackrod hole and the bottom arm mount to the chassis leg as well.





              Then made the cardboard and metal plates to brace the drivers steering rack mount





              and then cut some old strut top sections to be the strengthening plates for the strut tops.. Fitted far better than I imagined







              We have also been cleaning up as many seams as possible in the car and underneath to get as much of the welding done as possible before roll cage fitment.. Hoping to have a long day on Monday with Ste to get everything up-to-date.

                    In fairness - whilst Im doing the prep with a couple of friends help, its Ste that is doing the welding.

                          Thanks guys..

                          Had a long day on the car welding yesterday...

                          Struts stitch welded on the outside seams and 2nd skin added inside and stitch welded on



                          All seams inside and under the car now done from front chassis leg back to rear beam mounts / turrets





                          Drivers side rackmount bracing fitted as well.



                          Next step is to make it rolling ready for its rollcage fitting.

                            Nice work Paul. Coming together well with plenty reinforcement.

                                Weekly update time...

                                In order for the front triangulation to be fitted correctly, the inner wing must be cut to get a full weld. To facilitate this, I removed the strengthening pieces from the shell so that it will end up with overlapped pieces..



                                Then drilled out the spotwelds and removed the "bulged" strengthening piece using the panel splitter



                                Once that was removed, I then made a vertical slit in the middle strengthening piece and removed that



                                and then marked up the actual inner wing with a cut line so the rollcage installer can cut and reweld that piece.



                                I also made up some cardboard pieces and metal plates for the passenger rack triangulation.



                                We then refitted the rear beam, springs and dampers and front suspension assembly and took the shell off the jig.



                                Then loaded it up on the trailer...



                                and dropped it at Tornado Motorsport for the rollcage to be fitted..



                                Hopefully pick it up next Tuesday fully installed!
