• Custom car wheel arch and engine air intake development

    The crew at Joe Bradley Fibreglass have been hard at work filling in the missing pieces of the back end of the Ligero, and it’s beginning to look more and more like a car every week! The first matter of business were wheel arches, and after looking at options to fabricate them out of sheet aluminium it was decided that fibreglass was in fact the way to go, and they’ve come up a treat.

     

    It’s a snug fit between the radiator hosing and the front of the wheel arches, but it all shoehorns in nicely.

    Making the wheel arches mate up neatly with the removable rear clamshell has taken some finesse, but Will from JBF is more than equal to the task, creating intricate returns and brackets where required.

    Also under construction has been the vents to channel air into the engine compartment, as well as wooden mock ups of a couple of nostril vents that we plan to have on either side of the rear deck of the car to let the hot air out. 

    The donor Boxster is currently being carefully dissected, with its vital organs being removed for transplant to breathe life into the Ligero. Whilst the Boxster will not provide the power that we want for the car, it is being used for simplicity at this point to get the prototype to the road testing phase. A separate project is underway for a 500hp engine option to be the evolution of the species, but for now we’re going to walk before we run…

    Until next time. Dan.

  • Custom car build update: Delta Ligero June 2017

    After a few months of delays and planning work, Delta is kicking off the next phase in construction of our Ligero prototype. The fiddly jobs of plumbing in the radiators and mapping out the exhaust system are complete, and after a lot of deliberation we’ve decided to change tack with the power plant for the Ligero. Whilst the AMG donk and Porsche 996 combo would have been perfect for the task, it proved to be a little complicated and expensive for what we wanted for the car. Furthermore, with a view to limited production of the cars, that combination would be a little too unique for reliable sourcing of parts for future cars. With all that in mind, we’ve decided on a Porsche Boxster as the organ donor for the drive train for our prototype. By cutting away the AMG donor, we’ve also liberated ourselves of the constraints of the AMG mid-clip that we had planned to use for the centre of the car, and was causing us headaches in the cabin and leg space departments. It’s been back to the drawing board to some degree with the new plan, but in the long run we feel that it will be a much better solution. The Porsche engine will obviously not supply the power of the AMG engine, but we have a plan for that as well! First things first however, we want to get an operational prototype on the road and then look to refine the car by trimming weight and adding power. 

    Here’s a few shots of the car as it stands:

    The rear bodywork has had its cut lines inserted to allow for a section to be removable to give access to the mechanicals for servicing. The remainder of the middle bodywork seen will be bonded to the space frame. 

    We’re now in the process of creating ductwork to create airflow from the side intakes over the radiators and into the engine compartment. There’s a video walk around of this below to show the progress in that department.

    It’s all systems go now on the development of the front and cabin sections of the car now. We’ve sourced a Porsche Boxster donor car, and the process of transferring the components we need from it is also underway. More to follow soon!

  • Delta Ligero custom radiators are in place!

    Work has been progressing at a steady pace on the Delta Ligero prototype, with Andrew at Tricky Performance Engineering honing in on the rear end of the car and concentrating on the radiator and exhaust systems. The main consideration for the radiator setup for the car was naturally primarily to provide an abundance of cooling capacity for whatever engine the Ligero ends up getting, with a little extra capacity to account for forced induction if we go down that path. A secondary consideration was the weight impact of the radiators and their full coolant load, with the goal of the system as low to the ground, and as close to the centre of the car as possible to minimise any potential impact on handling. After considering all of our options for single versus twin radiator systems, and various mounting positions, we went with a set of RX7 type radiators mounted one on either side of the car, just aft of the rear wheels. This position will allow optimal airflow to be ducted from the hip and shoulder air intakes of the car, through the radiators, and then out through the vents in the back panel. Once sourced, the radiators had to be modified somewhat to suit our needs, and all the piping in and out is custom.

    The radiators fit snugly inside the rear wheel arch, in between the outer bodywork and the 45 litre aluminium fuel tanks on either side.

     

    From the rear of the engine bay looking forward the view looks like this:

    We’re expecting the exhaust cans to come back from the fabricator in the next week or so and their mounts are eagerly awaiting their arrival! 

    The mockup of the exhaust cans, as well as their dimensions drawn on the outside of the bodywork,  can be seen below. 

    The plan will be for the car to head back to Joe Bradley Fibreglass once the exhaust cans are in place for the next phase of bodywork to complete the rear wheel arches and a duct system to feed the radiators and vent hot air out through the back of the car.

    Thanks for looking! Until next time…

     

  • Custom fuel tanks. Welding and fabrication artistry!

    The 5.5L AMG power plant is going to need plenty of juice to keep it from going thirsty! Having stage one of the chassis completed allowed us to have twin fuel tanks fabricated to fit one on either side of the engine bay. The work that the contractor did on their construction was nothing short of art. They will fit snug and low in the chassis to keep the centre of gravity way down near mother earth, and will be connected via a pipe running through the engine bay. At 45 Litres a piece, they will be capable of holding plenty of fuel to keep the big V8 happy!
