A quick report of our trip to the WOS meet. We ran our fastest ever speed, 195.75 but we were fighting an engine oil blow by problem on every run. We would get back to the pits and drain about a pint or more oil from our new catch tank and we would have a lot of oil that found its way into the bottom of the car. So the motor has a date with the guys at Engine Dynamics for a freshening and a look at what the case pressure problem might be. Duke also could not get into 6th gear so that is another item for John and Mike at ED. I was pretty sure that we needed less gear so we installed a 15 tooth primary sprocket in place of the 16 tooth sprocket and even just using the first 5 gears the 15 tooth would give us a 200+ number if we could get the motor to 12,000 in fifth. The run started well but Duke said the car had a strong pull to the right so he shut it off at the 2 1/2. We did go 185 at the 2 1/4 which was our best time for that clock. So it was pulling great.
Things that we did that worked well: MSD ignition: This modification worked really great, it never missed a beat and made starting so easy because of the great spark. It took a little work to get it to fit the engine but was really worth the effort.
AEM AQ-1 data logger: Duke wired in the data logger and programmed his lap top to down load the data into. We only were looking at the AFR from an 02 sensor in the exhaust, fuel pressure, and air box pressure. The 02 info was great, we could see the results of each jet change and now we are starting to log this data to give us information for future set ups. The fuel pressure info is going to require some additional analysis but good info to know. The air box pressure data was the only one that I was disappointed with , not because it was wrong but because it was showing that my air scoop was not doing its job! Even at almost 200 mph we were not seeing any additional inlet air pressure for the engine inlet. Back to the drawing board!!
We already have started out "things to do for next year" list and are starting our planning and design.
We had a great time!!!
Rex and Duke
