Chump Parts

Parts are coming in to prepare the MX-6 for being a Chump. Lots of parts. A full inspection of the KL has made it obvious that some serious maintenance items need to be addressed. The valve timing was off enough to cause the rear cylinders to go flat on compression. Upon correcting that, compression is back to a usable level. However, with the tear down in place to correct that process, it is in our best interest to go through …

Dec 26 2013 Bill Events No Comments

Trying to get a grip on the 2014 upcoming events. We have decided to take full advantage of what NASA has to offer and curb some of the operating costs by working some events as a volunteer and then driving in the events we aren’t working. The best method we can see to this is to work as many non-Mid-Atlantic events as we can. This way we can best capitalize on learning more about NASA while not falling behind on …

After the 2013 season and the on again, then off again, then on again conversations about running endurance races, Twitchy Racing driver Michael picked up a candidate for Chump Car racing or LeMons. Keeping with the mostly Mazda powered corral of Twitchy cars, this candidate comes in the form of a 1995 Mazda MX-6. With nearly 230,000 miles on the clock, the KL (V6 for those out of the know) powerplant looks a little worse for wear but seems to …

After each season, you have to take a minute and reflect on the positives and negatives of both your accomplishments as a driver and the car’s capacity to move forward. For the #62 MX-5, there are several areas where attention is needed. The car performed exceptionally well, so well to the point where the need to circle back and readdress safety equipment becomes a priority. Out goes the old (but very adequate for previous purposes) Hard Dog roll bar and …

With a full weekend of racing spread between northern North Carolina and Central Virginia, we were looking for a place to stay overnight to split the drive time up a bit. As luck would have it, a northeast race team was going to be bringing their RX8 down to Virginia International Raceway for the 13 Hour Headlight Brigade endurance race by SCCA. The team, RST Performance, actually acquired one of our old RX8 chassis for another build back in 2012 …

EFI wrap up

After situating the fuel system, we needed to finalize the EFI wiring. We had figured out all the pins needed and the general layout of the harness. Plan done, execution needed. First, mounting the ECU. We wanted it easily accessible but not exposed to too much heat or potential moisture. Built a small stand for it off the passenger floor and then built an extra grounding strap just to be safe. After that, punched a hole for the factory EFI …

The car clearly had a good builder once it’s life. A builder who cared about how fuel was going to get delivered to the engine and keeping the car competitive within the ITA rules. This allowed us to inherit a 22 gallon Fuel-Safe fuel cell with custom rear firewall, fuel pumps and filters. Unfortunately, the pumps were of no use for us. A typical carb setup only requires anywhere from 4 to 7psi of fuel pressure and lower consumption than …

After getting most of the wiring laid down, we needed to address an important part of this engine swap. The cooling. The 13B engine requires a good bit more cooling than the 12A required and unfortunately takes up more real estate in the engine bay than the 12A as well. We knew the fit would be tight with how the previous builder mounted the radiator and oil lines in the car so the plan early on was to mount a …

I wasn’t really sure the best way to word this section’s title, so we’ re just going to call it “getting it running” because although the swap is not terribly difficult, there are lots of little things that need to happen to get this 13B into running order. First off is the wiring setup. We took the entire engine harness, ecu and misc chassis harness bits from our donor car in order to make the 13B EFI happy in it’s …

I got my new steering wheel installed today. It wasn’t in time for yesterdays autocross, but at least it is ready for OctoberFast. I installed the NRG 320mm suede wheel using the NRG short hub and NRG quick release 3.0. The quick release is in preparation for the roll cage to make ingress/egress easier.
