That pump might be just what I need. I think I can get one cheap. This post is related to a number of current topics on the forum.
There were a couple of options I had for building the new motor. One is to build it as an NA engine with a bumpy cam. They do make these and to be effective, I need to enlarge all of the valves to 5mm over standard, have some extensive machining done to the head, install a shim-under-bucket kit, knife edge the crank, reprogram the black box to a 9,500 rpm red line (1,100 rpm more than it is now), and retune the intake and exhaust. The target rpm would be 9,000 with 4,224 fpm average piston speed. Now it is 7,300 rpm with 3,250 fpm average piston speed.
The 994 cc engine as it will be tuned this year will make horsepower in the mid 90's, hopefully. It was 84 hp with the old 865 engine in a pretty worn condition. I am using the same cam in the new motor as I used in the old. It is bumpy but it is not Mae West.
The same motor I will be running this year, with the big bump cam option, will make maybe, with good tuning, power in the low 100's. A 10 percent increase, at most. It will be expensive to maintain. I have a piston wear problem now, and with all those more rpm, things will not be any better. I makes no sense to spend a lot of money going the high rpm N/A power route. Lots of cost with not a lot more horses.
This is something I figured out a year ago when I had to make a choice of piston rings: thin rings for reduced flutter at high rpm, or thicker ones to seal better at lower rpm with high cylinder pressures. Also, I decided to not knife edge the crank. Enhanced aspiration was the only route to big speeds I can afford, I figured then, when I ordered the parts to be made. Everything I am doing now is geared toward this end. Right now I do not know exactly how I want to do this, a turbo, fuel, spray, or a combination of these? This is something to keep me busy when I get back from AUS in 2015.
One problem I have is I do not like to blow up engines. My favorite method is to sneak up to the optimum settings from the safe side. A big problem on these engines is the timing curve. It is programmed into the box by people in England. It is hard to get quick changes this way. My black box was gone for a few months getting redone. Also, they do not tell you exactly what they are doing to the curve.
A few minutes ago I found a programmable black box on the internet. I can program my own advance curve and red line. Perfect for the enhanced motor tuning. I can start out a little bit retarded and inch up to the best setting, degree by degree, during a single dyno session. Things are slowly falling into place.
