Cobra II Brushless Fuel Pump tech@aeromotiveinc.com. all the nhra prostock bikes run them. In our case, I believe an auxillary would steal more power than it would gain. A much better system than the timed breather, and less oil leaks. The engine architecture of every engine except singles and 360 twins makes your statment true. You are using an out of date browser. I have used the Moroso exhaust kit on V8's and you get a right nice little pressure/vacuum surprisingly high actually, have you actually tried one of these set ups, Real Steel sells the kit. Creating a vacuum does take work, so it does load the engine and affect air/fuel ratio. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Cars will use an oil separator in the breather caps to prevent that, along with the one way valve. Once the oil is pressurised by the pump any vapor bubbles will condense back into the oil. 20"Hg = ~10psi or so. This ebook covers tips for creating and managing workflows, security best practices and protection of intellectual property, Cloud vs. on-premise software solutions, CAD file management, compliance, and more.

For a better experience, please enable JavaScript in your browser before proceeding. Two crank pins like a car is also a recipe for disaster, or it makes the motor too wide ( nice article in the new Cycle World). I've heard of some superbike motors (and plenty of drag bike motors) using a small electric vacuum pump for the crankcase breather. A somewhat sweeping statement, but I dont think it mattersand should still work fine - whybecause on every inline 4 F1 engine I have seen each ''sump'' under its piston is separate and does not cross talk to its neighbor either - so a single cylinder as such. ). http://www.starvacuumpumps.com/viewP=STR.04.06.000. Triumph twins used a timed breather on the inlet camshaft, venting to atmosphere, creating another oil leak, and by the '70's HC emissions. Are you going to try a vacuum system on your VRod? JavaScript is disabled. Has anyone used or come across such an application? For a better experience, please enable JavaScript in your browser before proceeding. At what point would a vacuum pump begin to draw the oil out of the engine? I think if you use free sources of vacuum it may not be a problem so much. On some engines you certainly could loose low end power and efficiency i think if the source of the vacuum is a vacuum pump that has a moment of inertia, an added belt or belt length, etc. https://www.enginelabs.com/tech-stories/tech-crank https://www.gzmotorsports.com/vacuum-pump-guide.ht https://www.chevyhardcore.com/tech-stories/dyno-te https://www.hotrod.com/articles/dyno-tested-vacuum https://res.cloudinary.com/engineering-com/image/upload/v1561146230/tips/20-vaccuum-pump-dry-sump-dyno-test-hpr-e1511374419296_shw4dl.webp, https://res.cloudinary.com/engineering-com/image/upload/v1561146237/tips/21-vaccuum-pump-dry-sump-dyno-test-hpr-e1511374468346_n787wq.webp, Low-Volume Rapid Injection Molding With 3D Printed Molds, Industry Perspective: Education and Metal 3D Printing, The engine may provide an adequate vacuum pump for half of the crank case revolution, being a single cylinder displaces lots of air, I was just going to put a check valve on the breather line, The engine already has a dry sump setup. I could picture a vac system, but couldnt remember who's. The breather lets air in (filling any vacuum) and the PCV lets air out (releasing any pressure). I was kindof operating on the presumption that if horsepower output is improved without changing anything with the air/fuel system or air fuel ratio we must be turning more potential energy in the fuel into useful work. How does one hold a vacuum in the crankcase without eliminating it's ventilation system? Sales and Tech Support: 913-647-7300 Already a Member? Other designs have a piston going up when one is going down and need the auxilliary pump to get as much vacuum. exhaust pulsations) you might as well use it. Ideas ? Has anyone done one of these ? It would be interesting to hear how it worked and how much of a improvement it makes on a 2cyl.engine. Rebuilding Yamaha Vacuum Operated Fuel Valves (Petcocks. Don't know, just an educated guess. Both can be used to assist piston movement. It is Suitable for use with Ethanol, diesel and gasoline and Fuel Pump Jumper Harness We might be able to scavenge some parts ? Come join the discussion about modifications, troubleshooting, maintenance, performance, classifieds, and more! Now install a check valve in the head the releases pressure and note it takes less work to push the piston in but more to pull it out. Good Sunday for Rinaldi: P4. The vacuum you can achieve will depend on the crankcase volume at BDC eg if this equals swept volome, the crankcase volume will vary by a ratio of 1:2 and the best vacuum possible will be about 1/2 atmosphere. The vaccum in the crank case lets the rings seal better. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Forget the schematics above, they don't apply. Ste A Internal crankcase pressure is expelled through the breather on the down stroke. The breather typically has a one way valve to prevent the rapid influx of outside atmospheric pressure on the piston up stroke allowing the average crankcase pressure to be a few inches of water below atmospheric. in the motorcycle racing fraternity it was common to connect the crankcase breather to a venturi in the exhaust pipe with a reed valve in close proximity to stop oil leaks and create a negative pressure / vacuum in the crankcase. Supercross Finally Returns to a Post Covid Seattle as Fists Fly in the 250's, Bikeland is Old Enough to Drink (without having to cross the border), SUZUKI & SAMPEY MOVE CLOSER TO NHRA PRO STOCK LEAD, Another 1-1 Overall Win for Jett Lawrence at Millville MX, Monster Energy Kawasaki Secures Double Podium in Millville, Monster Energy Pro Circuit Kawasakis Shimoda Keeps Podium Streak Alive in Millville, Gajser maintains 125-point lead after round 13 in the Czech Republic, Great second place for Bautista in Race-2 at Donington Park. Don't forget to plug the two no-longer-used holes in the airbox. Seems like we could do this with our valve cover breathers & pick up a few hp. Easily mounts in place of the water pump. Join your peers on the Internet's largest technical engineering professional community.It's easy to join and it's free. Simply loosen the lock nut and turn to adjust. It is Suitable for use with Ethanol, diesel and Cobra Brushless Fuel Pump Thats my excuse anyway I'll have to look at the Ducks. Has anyone here done that? on the down side wrist pins and valve guides can gaul from lack of oil . Close this window and log in. They're certainly small enough and already 12 volt. ok one other thing that came to mind, is it possible I could actually create cavitation at the oil pump pickup tube? Attaches directly to the Aeromotive Vacuum Pump. Most drag cars run them, in fact they add electric vacuum pumps & realize about a 3-4% power increase. Most single cylinder engines create crankcase vacuum on the piston up stroke. Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations. I use a power brake check valve myself, just like the one on my Triumph. If it did, you wouldn't see it at the filter. Interesting.please tell more, anyone have pics. The pistons do not come up at the same time on a Revolution engine.There is absolutely nothing in common on a Revo with the other style Harley engines. Ducatti runs this on their bikes. First, why discriminate against pressure and use only vacuum? Will take what ever I can get on the cheap. I agree. Why not. Both pistons go down at teh same time.

Aeromotives new Vacuum Pump Regulator allows you to control and adjust crankcase vacuum easily and effectively without the use of shims. Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. However, on a bike we can't run a belt driven system, an exhaust driven system is innefficient so it only leave a electric pump. the pistons go up and down at the same time (only one crank pin) (not like most cars or other bikes) and create huge crankcase surges. Bulega finishes on podium (P3) in WorldSSP. You onlu need the one way valve from Real Steel and they sell them separate, the rest you could fabricate yourself so should not be too costly to try. the crank evac systems used on serious race machines add hp (less windage) and allow the use of low tension piston rings for even more power gain. There is absolutely nothing in common on a Revo with the other style Harley engines. Home of the 9 second street ridden 1130cc VRod. There may be a tiny power boost but the negative pressure on the oil seals is probably the biggest benefit. This pushes out great volumes of crankcase atmosphere. Click Here to join Eng-Tips and talk with other members! But for a single or 360 twin, the self pumping is quite strong. Eliminate the control valve and connect the crankcase vent fitting to the fitting on the head leading into the air-suction valve. The generic power brake check valves are only $5 at an auto parts store. Better seal is more power. Could something like a windshield washer pump be used as a vacuum pump? If you're going to use it as a vac pump, then you may need to think about lubricating it somehow. This product is not legal for sale or use on emission-controlled vehicles except when used as a direct replacement part matching OEM specifications. vaccuum is huge NOT that im doing it, but you can also use the exhuast as a vaccuum pump, if you install a bung in the right place, at the right angle and plum it in the right direction. some old wise tales use to say that on a gsxr 1000, conecting the clean air exaust vents to the breather makes 2hp. http://2wheeltuesday.com/2009/03/wsillegal-engine-aid-to-outperform-competitors/, http://www.roadracingworld.com/news/article/?article=30270, http://www.roadracingworld.com/news/article/?article=13528, (You must log in or sign up to reply here. I doubt efficiency can be improved by selectively exploiting vacuum. But still worth a go, only way to know for sure. In the ideal case, a pair of pistons would move 180 degrees out of phase (as in a boxer engine) so both would benefit from the vacuum. I would just make sure you keep an eye on the oil level after long runs. Designed to work with the Aeromotive Vacuum Pump. Run'in on Empty, but the F'in gauge doesnt work, so I probably have 1/2 a tank! How much do you think this would help on a lil SV650? If it is a one cylinder motorcycle engine that has the gearbox sharing the sump (which is the usual design), the crankcase pressure fluctuation might not be all that much, due to the extra volume of air contained in the crankcases because of the gearbox. The vacuum inside the crankcase may overwhelm the ability of the high pressure low volume pump to get the oil out of the crankcase and into the oil tain, if not, just a check valve combined with the high volume low pressure pump may provide vacuum through the whole crankshaft revolution, the vacuum, since the volume inside the engine is not always the same, will pull the piston down through at least half of the crankshaft revolution, the vacuum amount in the crankcase may be hard to measure with cheap tools since it will probably change a lot, the inconsistent vacuum may not provide all of the benefits. I know the case is fairly large, but there's a LOT of stuff inside, plus oil. Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. I'm confused. The vacuum you can achieve shouldn't be directly tied to the radio of volumes. Thanks for reply. *Eng-Tips's functionality depends on members receiving e-mail. Now install the head lots of work is required to push the piston in, but you get some (not all) of it back when you pull the piston out. Learn methods and guidelines for using stereolithography (SLA) 3D printed molds in the injection molding process to lower costs and lead time. Already a member? I beleive they are just using catch cans,not an evac system. So they did away with the timed breather, and vented into the primary chaincase, giving somewhere for the pulses to go, then a simple oil trap and long hose to the rear. I doubt if it's worth designing and building a vacuum pump to do it, but you have a free or almost-free source of it (e.g. For use in Drag Racing Applications.
