The 962C valve oiler installed. Note the significantly larger oil hole

 

Another trick we are using on the rods is referred to as EDM.

What is it and does it weaken the rod in any way shape or form?

EDM rifle-drilling is a method of pressure-feeding oil to the wristpin by means of a small hole EDM drilled from the big end (bearing must also be drilled) which passes pressurized oil to the pin bore. The configuration of our cross-beam rods with the central rib lends itself quite well to this procedure and results in no physical weakness from the process.

 

Fair enough was just wondering since it seemed like it had some aggressive cams

These cars are so clean from the factory that we're working with an environmentally friendly super car to begin with:P

 

alex,

These cams would be considered full race cams in a 3.6 liter motor. However, we are a full liter beyond in addition to the duration being a little lower.

 

Apparently displacement has its priveleges.....

 

Yes, size does matters.

 

I spoke with Neil today. He will have his work done by the end of next week.

The pistons will also be done next week. The pistons are going to be over the top. We want the motor designed to have the capability of running flat out for 24 hours although it will never be called upon to do so.

To accomplish this we will be eliminating the wrist pin keepers. The wrist pins will be coated with a compound known as DLC Carbon Coating (casisum). In essence no wrist pin keepers will be required and the pins will never gaul which can occur under high temperatures and pressures with other setups . The gualing is what leads to bent wrist pins. The pistons are designed internally "a la water cooled 962C" with an internal cavity under the dome which will fill with cool oil while at the same time exit with hot oil. The purpose being for the oil to act as a heat sink for the piston and then carry the heat away allowing the piston to run even cooler. Cooler motor allows more timing and boost. Plus being able to use nitrous when desired.

Will have some pics in about ten days.

 

Alex,

I'm was being a little less than truthful, didn't want to be followed so fast by others, but what the heck. Since the car will be a Sunday driver and economy (or volume of fuel consumed isn't an issue, not the price) isn't a factor ... E 85 is an option. It is being set up to run on 120 octane E 85. She will be a very enviromentally friendly. Besides it is only about $2.00 a gallon and is more readily available than 100 octane race fuel. The down side is you use about 30% more E 85 than gas to go the same distance. The upside is the 120 octane is you can run more timing and higher boost levels.

 

Still waiting for the pistons. Hope to have some pics soon.

 

All the parts, with the exception of the rods, are being shipped today. The pistons were really complicated. The wrist pins were raised up into the bottom ring. We could not use molly rings due to the nitrous. The rings had to be made of a lot stronger steel material. There is more clearance on the pistons and the liners required a different cross hatch.

Nitrous has a drying effect on the liners which drys out the oil on the liner walls. The different cross hatch and rings combat this by holding the oil on the liner walls.

Hope to get some pics to post soon.

 

I just recieved some additional information and I'm not exactly happy. We are making progress, however we will not make the June 16th day I was trying to make.

With everything we are doing to the pistons it took until today to figure how high we would be able to raise the wrist pins and still provide for oil cooling chambers under the domes. It also took until today to determine the final compression ratio that is going to be utilized.

The bottom line is we will not have the pistons finished until June 12th and then we will lose another week while the pistons go to Swain for ceramic coating for the nitrous duty.

With the 82.4 mm stroker crank our rod length will be 5 mm's longer than the stock rod length.

It now looks like we will have all the parts in our possession by the end of June with a final completion by the middle of August. Two months late.

 

Wow just wow, just when I think you can't make this race derived motor any better you find a way to!

 

I'll add one more. We are working on replacing the stock ignition system with a Capacitive Discharge System with coils almost three times larger than the current stock coils.

The much larger and faster generated spark will greatly assist what we can do with the tuning.

 

Next your going to run this system with a trionic engine management system that takes instant A/F readings each fire of the spark plug by running an ionic charge thru them after they fire!
