Well last year was disappointing, the sled would not rev (I believe it was the Voltage Regulator ), The NOS would pull hard to Mid-Range and done, a bit of Knock too.
It started leaking oil out of the waterpump weep hole, I thought.
Spark Plug tore out of the head, needing a new head to be chambered, flattened and milled.
The engine cases\cylinders threads on several holes are starting to strip. (94 Mach 1 Motor, 25 years old +/-)
So... the VR was upgraded to a Mosfet design, I hope that will solve the Revs.
The leak turned out to be the seal for the cases, I think the NOS and Knock caused the lower case seal to blow out, also upgraded to better pistons and cleaned and re-tapped holes.
Once the engine was in the chassis and started it was pouring coolant out of a head bolt, it tore the threads and there was not enough depth to increase the threads. I was going to helicoil it, but instead went with using a 10mm bolt since it was the same bore as the heliCoil.
We are back in business!!
Tidey up some electical stuff and maybe a little testing at the farm.
Untill the next "Earth Shattering Kaboom".....
