Well, what's kept me from one way valving the crankcase is an unknown in the design. Take any single cyl or variation of a v twin and just about all of them have a one way valve in them to bring the case to static or slight vac. The unknown here is why wasn't it done with the Revolution. Is there some underlying design intent regarding long term lubrication in some part of the engine or trans that a one way case venting could screw up some? I've not come up with the answer yet.

A quick search located a few threads where other forum members tried check valves to improve on the OEM crankcase vent system; e.g. this one.
In this thread an aftermarket oil catch can, check valves, and the MotoHooligan airbox are all discussed. (Ron, you posted in this thread).

Thanks for reminding me about repeating myself.
I did however come up with a one way breather valve head that replaced the existing cansister cap which a hose could exit out the bottom of the breather box and either to a catch can or just under the bike. Got as far as a quick sketch but no actual prints. I'm retired now so no machine shop available and not a lot of interest to pursue it. Me personally I get very little oil in the box but I do see some carbon on the intake valves from oil misting.

Interesting post here on detonation; https://www.enginelabs.com/engine-te...-applications/ Awhile back we had some discussion on the Delco Ion sensing algorithm. I still feel I'm better off to build a tune that doesn't detonate rather than band aid a bad tune. Comments ?

Agreed, but without a knock detection system in place how will you detect said knock to tune it out?

Reading plugs?
"Listening"?

See where I am going with this? I can elaborate much more, but the point is not to let the knock detection system of choice "save" you, but rather provide a critical piece of data to review and then work around (i.e. I had some knock counts at load X so I need to cut back timing there and add some fuel). No data? No way you will fight the knock effectively (or safely). At best you would be guessing.

Freudie, We're talking chicken vs the egg, I know. I'd use the algorithm if it was available, but its not. So either option requires a work around, right ? If I data log detonation, I still have to accurately figure out the cause to correct it. The link gives some great cause/effect explanations. Please keep posting & making recommendations, the dialog is great.

I had a thread about water/meth injection in another header. Has anyone built a system ? By injecting pre-compressor it seems we could lower intake air temps to increase charge density and increase anti knock potential from the mixture.

For a street application you are better off with an efficient air-air intercooler (or possibly air-water...but we are already constrained for space on a bike).

Meth or water injection works...but A. Is limited to the amount of meth or water on board of course B. Meth is VERY corrosive. I would only use this on a bike/car that you purge the tank and lines after using.

FYI...water injection has been used in airplanes since I believe WW2. Cool history.

Hah! You are opening Pandora's Box again so to speak.

I've made it very clear I don't recommend using anything except the oem Delphi controller for these bikes. No one has yet to make a convincing argument that the aftermarket (other than perhaps an all out race application) make sense for these bikes. You lose way too much functionality (ion-sensing being one of them). And once again...YES you can run boost and have timing/fueling changes based on MAP sensor readings with the Delphi unit. I know some members want to argue/disagree with me endlessly on that....so be it.

Freudie,, Post some screen shots & instructions on how to link & change the tables. What are some of the other functions ? Thanks

Post from Karzza 9 years ago

I have been using 2bar Delphi MAP (16235939) with SERT, and calculated downscaling
by using Delphis V output formulas.

SERT -> Real pressure
10kPa -> 7kPa
20kPa -> 28kPa
30kPa -> 50kPa
40kPa -> 71kPa
50kPa -> 92kPa
60kPa -> 113kPa
70kPa -> 134kPa
80kPa -> 156kPa
90kPa -> 177kPa
100kPa -> 198kPa

Downscaling means, what you have currently defined for example 90kPa you have to move value to 50Kpa position or fr 30Kpa to 20kPa.
From 60kPa up you have to invent figures by yourself.

https://www.1130cc.com/forums/showth...sing+stock+ecm

But in the long run he went with the VRFI and never regretted it.

Karzza and Jan-Dirk are the kings of the Boosted V-Rod. Along with a lot of blown engines that were sacrificed for development and always looking to improving it. Along with the wealth of information that they are willing to share with the forum.
