    Mine did a 1:32 with Oem turbo, so there is plenty left with that car. It would have felt very different to last time you went with aero and no power in your car.

      The Dave Moore car has a lot less grip and is much more streetable than a lightyear winged car but with its power level it's trickier to drive at the track.

        How about that update on the Track NB that I've been owing you all for oh so long? Well here it is!

        So finally back onto the Turbo track car.... and first up, I thought it would be fun to post up a video I put together of what it's like trying to start a car for the first time in about 2 years after an excessive collection of changes have occurred to the poor thing.
        The cars had a lot of changes between running from ecu retunes to turbo installs to new ignition system to completely different injectors to a change in the entire intake system. You can probably predict roughly how it goes.


        The cause of the start issues ended up being simple, in reworking the wiring for the ignition I had to donate some of my wiring loom to another car for a short while and in the process, the pinout on the deutsch connector for the coil packs had been switched... resulting in Cyls 1&4 firing when 2&3 should have been, and vice versa.



        Moving on, one of the breather lines was annoyingly close to the dipstick, and if you know anything about these cars, you know the dipstick handle is made of faberge egg... if you even just think about touching the dipstick it breaks.
        So to try keep the hose away from the dipstick, I found a spare 45deg bend AN fitting and it made such a simple thing seem so satisfying. Not strictly necessary, but it made me feel good.




        Regarding the forementioned battery from a few posts ago, I ended up designing a mounting bracket, and hooking the thing up to an anderson connector for easy disconnects or to attach a jumper pack etc. Mounted up under the dash so battery cabling is all very short and should save a nice amount of weight.

          Now if you've been following my posts via Instagram/Facebook you'll have seen I recently got this Electric water pump in and working.
          Why go electric water pump? Other than the personal challenge and my own curiosity in something different, it will allow for running the pump even when the motor has stopped, which will presumably be good for the turbo, it makes bleeding a breeze as theres no thermostat and therefore no need to run the motor up to temp to try flush out air pockets and it is controllable via the ECU.


          To get the thing in and working, I first needed to remove the old mechanical belt driven water pump (which was brand new sadly so theres $100 down the drain - doh!) and to get to the water pump, meant all the 'bits' on the front of the motor need to come off including valve cover and plastic timing belt covers, pulleys and the timing belt then lastly the water pump itself.



          In place of the old water pump I've installed a modified & gutted spare water pump. This pump has had a block off plate welded where the old impeller lived, and is needed to do 3 important things... 1) fill the big hole in the front of the motor, 2) Provide mounting locations for the timing belt pulleys, 3) provides the convenient location on the exhaust side of the motor where the water pump inlet housing bolts to...
          You can also see the slightly odd nakedness of having no water pump pulley. All I need now is a belt from the crank to the alternator. No other belt driven items on this motor anymore.


          Speaking of the inlet housing, that also copped some modification. I flipped it 180 degrees, shortened it, and blocked off the old holes for the heater core hard line and the small coolant line barb.


          With all that done, the new Electric Water Pump had a home to go to, and it fit right in. The pumps inlet and outlet are about 38mm diameter, wheres the Mazda runs 32mm hoses. So I found some aeropro branded straight reducers locally which fit perfectly on each end, and made the install a breeze. (now that everything else was modified to suit)


          The elec pump is now all plumbed into the radiator, and the inlet to the 'dummy water pump'. It sits in place just with the support of the silicone hoses, no brackets or other mounting is required.



          And, it's high enough above the bottom of the subframe that it shouldnt have any issues clearing the lower splitter and floor... And most importantly, the thing is pumping fluid! I ghetto rigged up a car battery to check it was all happy and it ran like a dream. Made some really amusing gulping noises for a minute or two before all the air was purged.


          Keep a look out as I've got a video coming in a week or two with more detail on the EWP if you are keen to see how it was done and want to hear my soothing voice talk you through the process.

          Cheers

            My brother has an EWP on his NA6 MX5.

            Was on it when he bought it and uses the Davies Craig controller.

            Seems to do a good job, haven't had a look at what they did to the water pump though

              I'd certainly be keen to see what others have done in that area. There's not a lot of info shared online around MX-5's with EWP's so I've made a lot of it up myself.

                It's bolted to a flange welded to the lower radiator pipe.

                I'll get him to take some pics and post them up

                  To finish of the water pump from last time, there was one thing missing, the wiring and ECU control.
                  So while the pump WAS working, it was pumping coolant, but it was just some temporary wiring.
                  As such, let me introduce you to the Bartine Engineering mosfet control board do-hickey which is triggered by the MS3 ECU to allow PWM control of the pump.
                  With this (and the help Alex's wiring skils) the pump is now ramped up dependant on coolant temperature so that it can function like a thermostat.
                  It seems to work well however time will tell once the car is up to speed and we can log coolant temps to see how they stabilse.


                  Also from a temperature perspective, I've wrapped my intake in this ebay spec gold tape. The stuff gives off a nice glow so I'm hoping it will help reflect radiant heat and aid in keeping intake air temperatures down.
                  I may also wrap the intake tube from the intercooler to the trottle body... perhaps I will see how this goes first. I'm assuming it will be able to hold up to the on track demands.



                  I've hit an important milestore, it's finally time to start thinking about finishing off the next phase of body/aero on the car. This is exciting because this is kind of all that's left before we take the car out for a real drive. (of course, the car is never 'done' but you get the idea...)
                  So a few items have started happening. Firstly, I've been considering redoing the front guards/fenders and cutting them in half, something like the shape shown with the blue tape line.



                  Secondly, is the new Lightyear wing that is going on the car. This is going to require a little bit of home engineering to get it mounted and fit up, and will need some endplates as the old ones appear to have been donated somewhere for the greater good. How do you lose wing endplates?


                  Mocked up on the car just for a bit of fun, however it needs a lot of attention before it will be mounted up for the final time. New mounts, some cleaning up of the surface finish, and maybe a gurney flap?


                  So.... she's getting closer to being back in action now.
                  For the moment, we are going away for a short trip overseas to visit family and take a little time off. As soon as I'm back I have no doubt I will be straight back to it. :D

                    You can have my carbon fibre front and rear guards. But you will need to get some wide 10-11" rims and 275's. Or spacers. I decided to go the other way now, keep everything much tamer and simpler.

                      No thanks, too wide for my wheels and tyre availability will become a big issue then.

                        Still trying to decide what I do next with the fenders/guards. One option I'm considering is adding vents at the top LMS car style:



                        This however, won't net me any weight savings, whereas cutting away some of the guard will..... so I'm not sure. Perhaps I should do both??

                          Do you have a link for the ebay reflective gold tape?

                            Not the exact one, but something like this.

                              You can buy it at Motorsport Accessories at Brendale Sambo, recently bought a few sheets for the benz.

                                Cheers guys, ordered some last night. The bloke at MSA had been saying for over 12 months that he was getting the gold stuff in, just didn't know when. So they have it now? I've used the DEI stuff in areas, bloody hell its spendy for something that really isn't that tricky.
