Havasu Hangin' Lord of the Drinks. Joined Dec 20, Messages 1, Reaction score Blower surge is from a bad tune Goes too lean at idle. Joined Dec 19, Messages 18, Reaction score 3, My boat with surge if i start messing with the idle and mixture screws. Sounds cool, but the repercussions long term cant be good. Hallett Well-Known Member. Joined Sep 6, Messages Reaction score Mine kind of does it a little.
I like mine in stereo. Sweets videos guys. Blower surge is still cool. I doubt we will be having this conversation in 3 years about how lame it is like an Affliction or Ed Hardy shirt. Lucas Oil Well-Known Member. Joined Jun 30, Messages Reaction score Atmosphere conditions do effect idle so doze lobe center on cam shaft the wider the lobe center is the better the idle and timing is a factor.
But a isolating engine just needs the idle turn up. Sharp Shooter The "anti-yuppie". Joined Oct 4, Messages 5, Reaction score 7, I don't think it's a big deal either way Lucas Oil said:.

Joined Sep 24, Messages 6, Reaction score 2, EpicOne Voice of Reason. Joined Jul 1, Messages Reaction score 2. I found my blower surged when I was using poor oil. Maybe it was lumpy. I switched to Lucas Oil and now it runs a perfect idle BigQ Well-Known Member. Joined Jan 30, Messages 1, Reaction score My old CP19 did it. Hard to tune out becuase of the carbs even when worked for the blower and the locked out MAG.

To understand stand how and why surge occurs, we first have to understand the working principal of a centrifugal blower. In the volute the kinetic energy is slowed and converted to potential energy in the form of a pressure rise. As long as the outlet pressure of the blower is greater than the downstream pressure, the blower operates smoothly and efficiently. If the blower is slowed down enough or the downstream pressure rises suddenly beyond the capacity of the blower surge will occur.
Because the pressure downstream is now greater than the capacity of the blower, the air will now reverse and try to flow back into the blower.
This cycle, known as surge, will go on until the reason for this surge is corrected. Centrifugal blower manufacturers should provide curves which show a collection of surge points for varying speeds and pressures.
This line is called the surge line. This is the point where the blower will start to experience surge and should not be a point in your design.
Methods to Control Surge. If the pressure in discharge line is too high the modulating valve will open reducing the header pressure thus relieving the surge condition. However there is a concern this valve could reduce the header pressure too much and eliminate air flow to the process. This usually occurs after surge has started and does not eliminate surge.
Another method used to protect against surge is a blow of valve BOV on the blower. If the surge boundary is not adequate this method alone cannot protect against surge. Since most instruments alone are slow to detect surge a buffer called the surge boundary provides the BOV enough time to react. This surge boundary should be set so that the minimum flow the blower can run at a specific pressure and speed is equal to the surge point for a pressure 0.
Yes you can still use the blower , the hat will just bolt in place of the carb adapter. If it's a drag car , then a mechanical system will be just fine, if you drive it on the street a bunch then mechanical is a real pain. In Top Alcohol Dragster, the cars used supercharged " blown " engines , burning alcohol methanol. Blower speed is one. What is surging in centrifugal compressor? Surge is a characteristic behaviour of a centrifugal compressor that can occur when inlet flow is reduced such that the head developed by the compressor is insufficient to overcome the pressure at the discharge of the compressor.
Why is my engine surging? What is loping idle? Engine lopes at idle. We say an engine "lopes" or "surges" at idle when RPMs cycle unsteadily up and down. For example, a car may surge at idle between and rpm.
What causes a carbureted engine to surge? Incorrect idle speed settings or fuel mixture adjustments, and malfunctions in the fuel vapor recovery system can upset engine idle capabilities of carbureted engines.
