it should fire next week.
We tried on Friday night but the Original Ford coils gave us grief so I will put on those that are tried and test.
Everything is go so bodywork soon I think.

Front wheels with flat of set.
I had the casting machined to give the optical illusion that there is more rim.
I will need to modify the spinners as I may carve up pedestrians. | |

Hey Jim,
That is one sexy exhoust, I bet she'll sound as good as she looks! I always look forward to seeing what new creations Jim C has come up with. What is the oil cooler for? Engine or gearbox. I'm looking at making a cooler for the box in the near future.

Beautiful work. That wiper assembly looks beefy enough to handle not just a rain shower, but a major flood! | |

It will be quite as I have to get through the engineering (RTA).
That is my pryority.
The cooler is running exhaust gas to lower the NOX.
Chuck
Yes I dont think it will fall apart.
The rack and pinion I laser cut out of 316 10mm.
It works great better than I thought.
The problem is the sweep,you can not do it on a linkage as it goes over center,then the wiper arm runs across your front clip.
The rack allows you as much sweep as you want.

While I was doing the emission testing with the RTA, they never checked the noise levels of the exhoust, that was done by my engeneer. Thats a cool idea about cooling exhoust gasses to reduce the NOX levels. Good luck with everything and go to Penrith for testing as the operator is better.
Cheers

Jim, I take it from the above comment that you are running the exh gas thru the cooler on the way to the EGR valve, and you appear to source that from a small 'in pic' balance pipe just behind the collectors.

Thanks Bob

Yes that is correct.
Maybe you can shead more light.
I am still uncertain on the theory behind it.
EGR increases the combustion temp and reduces the NOX.
A conversation with my engineer he told me the cooler reduces the NOX.
The only puzzle I have is a turbo intercooler will increase the NOX due to lowered combustion temps, in theory that is what I am doing here so why does it work with the opposite reaction?.
Maybe it allows more volume because it is dencer or maybe you will require less EGR because it is dencer this allowing more room for a clean charge in turn making more torque and requiring less throttle and lowering the grams per KM readings in the test,I am shaw it will be a one armed juggling act getting the 5 gasses were they need to be.
I will be blocking air flow to the cooler when we go to the dyno to check the difference.
The EGR also is controled by my ECU so we will be writing a map to control the correct amount of flow at any given point.
