Thanks for the info Guys. Every bit helps. I am now set on the original crankshaft design, stick with what has been proven is a good starting point. The largest factor in the High Output design is the pistons. Increasing the bore from .375 to .5" will nearly double the displacement from 3.62cc...

So I am in the beginning stages of the High Output TI4 Design. My current firing order is 1-2-4-3, and I want to get 1-3-2-4. My thought is that the way it is now with the intake manifold having two runners connected to two pairs of cylinders, the characteristics of the flowing gas is not the...

I think maybe, perhaps, the eccentric has to be flipped 180 degrees on the crankshaft in order to reverse. But thats about all I "Think" I know. :shrug: Kel

Awesome, I could do that all day. I love seeing these engine put to work! Kel

Well Done Andrew! I really enjoy seeing these engines running, and yours is very nice. Kel

That was the Idea ;D I already started designing the "High Performance Upgrades" for it, I have a lot of room in the $6 million budget ;) jc vvv I am now seriously thinking into the oil issue. With an oil pump, how do I meter the oil to be certain that oil is reaching all the connecting rods...

Thanks for the tip George! I do plan on doing more hard testing with it to see how much power I can get from it, and an oil pump would defiantly help a lot, especially if I increase the bore from .391- .5 ;D Kel

Cool, a water brake dyno. How are you going to meter the water inflow and outflow? Well, I did it Now, I killed the little guy, but I am totally stoked at the same time. During yet another high load run on the dyno, the engine started to knock louder than usual, I knew it had to be that...

Thanks Jeff, What type of Dyno are you planning on using this weekend? Kel

Here is the new revised graph. This looks much more like the real deal. Kel

Ahhhh, I think I figured it out. :D My chart is in in/lbs. I did some conversions and found that the ft/lbs are indeed equal to the horsepower at 5252. I will have to re-conjigger the graph into ft/lbs. Kel

I guess I should refine my methods a little bit. ?So when I chart the torque an HP they should intersect at 5252 no matter what? and If they don't? Its only numbers, how hard can this be ;D What can I do to the prony brake to make it better? The valve seats are actually brass, but the...

I have been running the engine on the Dyno through many tanks. Through small adjustments of valve lash, timing, and fuel mixture the TI4 is running stronger than ever. I am now seeing torque numbers in the .9 in/lb range and holding there at around 5500 - 6000 RPM. I am incredibly surprised...

Great Job Chuck. Perfect balance throughout all speeds! Brilliant Indeed! Kel

Well I spent the last day collecting data on the Dyno. With adjustments to the ignition timing The TI4 is now holding the torque more effectively. This is an average of a few runs, error on the high side. I am absolutely confident that the engine has more torque with the lapped pistons. The...

Any time I need to mill a radius on something I get out the rotary table. Her are some pics of things I have done on the R/T that cant be done on an indexer without some way of turning the table while milling. A hall sensor strap for the TI4 Distrubitor Timing Cover Here I am milling...

Brian, FWIW I have made a few built-up crankshafts by reaming a hole .001" undersized (Much cheaper than a tapered reamer) and pressing in a short length of drill rod. Just be careful when pressing not to distort the crank. I have also made a hole the same size as the pin, with a slight...

Thanks Gail, your post on the Tiny was a great help in getting this engine running at where it is today. Jeff, I had thought about that, but I think two carbs is twice as much trouble, but it would be cool though. John, the engine needed a full turn or more on the needle to get it running, but...

I have been playing with new piston designs, mainly getting rid of the o-ring, and trying out rings or lapped pistons. My first attempt at rings was going good until I tried to start it, and there was virtually no compression. I took the engine apart and checked the bores. I found them to be...

About the batteries. Since batteries are for "Mobile" devices, is there any reason you can't hook up a power supply directly to the unit? Perhaps an old cell phone charger, or other transformer with the correct voltage and current? Just a thought. Kel
