It depends on the engine type whether or not a load dyno is appropriate. Most forced induction engines in vehicles are NOT good load dyno candidates; this is because the vehicle weight becomes obscure when searching for optimal timing. In other words, a load dyno can apply whatever load you...

I suppose you are not sure what direction to take, are you asking for options to bridge the two ideas? Lets use an example random engine then. The steps would look something like this: 1. Measure the oil output for maximum duration. All engines will eventually leak oil somewhere. The question...

You are going the right way. Here are some more ideas for you to consider. 1. The weight of the engine and its drivetrain plays a role. Two 4L engines or 2L engines can have dramatically different RWHP numbers because one of them could be 4WD or have a heavier rotating assembly. 2. the...

There is no difference. anything that traps or collects solid/liquid while allowing the passage of gas (air molecules) is an A/O separator. Lets use a different approach. Imagine the engine is a cup that you fill full of some kind of oil, you can use any cup you want. Think of maybe, a...

Imagine you connect one end of a tube to the crank case, and the other end is on the intake manifold. Use different length tubes; 1" 1' 10' 100' 100000' Now compare what you find inside the tubes of different length. The 1" tube will be coated, perhaps even clogged with oil from a...

That does not sound right. If a large quantity of oil goes into the exhaust system of a broken engine, the engine is no longer making power (it broke) and the temperature will rapidly be cooled by the sudden addition of liquid oil. Furthermore the exhaust system is well contained, and...

thanks for the questions :D First lets talk about vapor. How is your chemistry background? A vapor, can/should be called a gas. Gas state molecules will NOT stop in a catch can. A catch can is going to trap a liquid or solid state molecule only, and even then most of the liquids and byproducts...

To time the engine, take the vehicle to a dyno. An EGT gauge should be used if possible. You want to be reducing timing as much as possible, until the EGT begins to climb notably, and the torque drops notably at the same time. Once you find this point, there is a diminishing returns with...

Ideally there are no catch cans. A catch can is to catch oil when you have no other option (you cannot fix the oil 'leak'). In other words, the engine should never spill out oil under any circumstance; if it does, there is a baffle issue, it requires a baffling modification (take the offending...

if you are looking to do the math, here is a handy equation I use, cid x rpm / 3456 = CFM * 0.086 = lb/min For example 355x6000/3456 = 616~ * 0.069 = 42. lb/min, or 420 flywheel horsepower To factor in boost now, multiple lb/min by pressure ratio, so for 14.5psi of boost you multiple by 2.0...

Oil viscosity needs to match the engine's clearances and use. If I have a tight engine with .0008" bearing clearances, such as many nissan/toyota engines come OEM, I will need to use an 5W-30 or 10w-30 oil (as temperature goes up in our climate, we use thicker oil also, according to the FSM)...

1. There should never be a filter (breather) on any PCV design, ever. Allowing the atmosphere to exchange gasses with the PCV system eliminates your PCV action! 2. The best design will minimize the crankcase pressure during boost. The lower the pressure in the crank case, the more power the...

I just noticed you have it all wrapped. Hows the wrap holding up? how do the plumbing manage it? Does your car see rain? Usually wet wrap on exhaust plumbing is a bad combo. So I am wondering how you manage that... maybe just dont drive it when it rains ? :D Intensely curious because I myself...

just keep it as simple and short as possible. Do not T-off anything that is important, like your fuel regulator, wastegate, bypass valve, map sensor, boost controller. Always on every car connect the fuel pressure regulator!

well of course it would be interesting if we knew what the pressure is in our exhaust systems, but few people monitor this detail or stand to gain little more than an idea. Your guess is as good as anybodys what the real pressure differential is that exists along a length of tube, after or...
