Restricting his flow with a washer build up his pump pressure and the pressure in the block helped reduce the onset of hot spots on his cylinder walls and formation of steam pockets. If it was as simple as installing a High Flow Pump wouldn't the General of figured that out. Just change it if you want if you have problems start changing other items. 
The extra pressure, and the fact that the coolant is not left too long against the cylinder walls, will stop it from over heating it and boiling off. Restricting the fluid flow to raise system pressure in the block may help prevent cavitation at higher RPM but is it necessary for most vehicles? Restrict it further and you may as well hose clamp the lower radiator hose and we know how that works out. 4. fewer rows of tubes. FlowKooler pumps are designed to move water more efficiently from the radiator to the block to keep you cool. Pre-ignition results from the air/fuel mixture igniting in the cylinder before the spark plug fires from an ignition source other than the spark.
Ask Grandpa and he might tell you his overheating woes came when he tore up the track at high speed. Unfortunately, the block is the part that is generating the heat. Cookie Policy - I started tearing the car up today for my cam install. In any cooling system, the components need to be reasonably well matched. The Fora platform includes forum software by XenForo, http://go.jeep-xj.info/HowtoWaterpump.htm, VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. An electron moves at varying speeds - Bohr's model has it moving at 2 million meter/second. Heavy duty vs. high volume water pumps, what's the deal? A forum community dedicated to Ford Mustang owners and enthusiasts. Engine blocks machined with limited or no cooling jacket can result in steam pockets and hot spots. 3. FFR3842, 363ci/600hp, AFR205's, Wilwood 6/4 piston Superlites, Koni DAs, Magnesium bellhousing and Tilton Triple disk clutch, GF5R dog ringed 5 speed, 3link, VPM sway bars, Hoosier A6s, CCW forged wheels, wings, undertray, diffuser. All Ford Mustangs | Model Specific Forums. The proof however lies inside the pump. In other words we check the Tempature going in and out of the Radiator and or Engine. The engine is still generating heat the whole time so why keep the coolant there any longer than you have to. We discuss MK4, GTM, 818, Type 65 coupe, roadsters, and more! Do high flow water pumps offer any real benefit?
Debunking the I Can Have It Both Ways Theory. Northern Great Plains and Rocky Mountains, Signature Pictures and PhotoShop Requests. Flowkooler pumps increase the flow and create highway-speed flow rates. I can unsubscribe anytime to withdraw my consent. But a lot of people still think so. The overheating could be the result of cavitation in his pump due to the higher rpm. glad you mentioned the 250 and 350 most people have forgotten those. Bob, FFR5020 MK III Whitby body +paint, sai mod, Tremec,408, Cobra/Oben brakes , Halibrands, mass flo , gas n pipes, levy rad team3 spinners.Fortes driveshaft, pulleys ,and quick release steering.. For a better experience, please enable JavaScript in your browser before proceeding. That was back in the days when you buy a 2 core Ford racing rad cheap . These bubbles eventually implode and damage the engine block wall and impeller. Engines at idle, engine cruising at slow speeds or engines stuck in stop-and-go conditions have something in common; lower coolant flow rate and reduced air circulation through the radiator. So, I needed a heavyduty Griffin aluminum radiator, 3000cfm fan with a stock wp. A lot of people. At idle the creation of a hot spot at the top of the cylinder may be enough to cause pre-ignition. The two 354 Hemi's I have run a BBC pump, nothing special. That block pressure helps squeeze air out of the system that will impede your heat exchange. Bolting the engine back up and have been told by other forum members that the high flow water pump is the way to go because of the angle and cooling ability of the radiator in the MkIII. We have come up with some explanations for the Doubting Thomas. Mine is a small block, but I switched to a LOW flow water pump, by Moroso. When we have a new Engine installation and we do the first Sea Trial if we only have say a 10 deg drop then we put a flow restricter in to slow the flow down until we get our 30 degs. water jacket, thermostat housing, thin tube aluminum radiator etc and the cooling system passage itself becomes restrictive pressure builds in the block. We have use pressure caps since the late thirties to remedy this. Anyone change one out??.. Some people worry that it can be worse as the water doesn't stay in the radiator long enough. Privacy Policy. Boring is great for getting more power out of your engine but notorious for contributing to overheating. So if I get this water pump and replace all my hoses with new factory replacment ones I should be golden right? When ever I hear praise about any of the Kawa triples I cringe. Restriction is not all bad if it serves to prevent cavitation. Your engine coolant's electrons do not know (or care) how fast you send then through the system - they just knows that the source is hotter than the sink and off they go. My last engine was roots blown, 450hp. These design elements are incorporated into the impeller for one purpose; to generate more flow to cool hot engines. Discussion in 'The Hokey Ass Message Board' started by 31Vicky with a hemi, Apr 21, 2013. Privacy Statement - Terms of Service. But let's just agree it is fast (really really fast). Increased flow helps cool a hot engine byreducing the cycle time between the heat source and the heat sink. I had similar experience with my 427. Engine/Drivetrain/Suspension Parts for Sale. Half of you are saying stock is adequate, the other half of you are saying yes.but it seems the common thread is a dewitts radiator, not just the water pump alone. Debunking Grandpa's Flathead Washer Theory. Found my first car, should I buy it back? In the Marine Industry we use the 30 deg rule. Are there any advatages to be gained from a high volume water pump on a 5.0 with electric fans? In loving memory of lost CorvetteForum Brothers and Sisters. Do Not Sell My Personal Information -, By logging into your account, you agree to our. Ping heard when the engine is shut off may be the result of pre-ignition. The lower rpm reduces the cycle time between engine and the heat exchanger (radiator). The pumps continue to deliver higher flow all along the rpm curve and when system throughput is maximized, FlowKooler pumps build block pressure. No. Elaborate please. Had a Team G Weiand that failed on it's first outing. JavaScript is disabled. This increase exposure creates more opportunities to shed heat and drop the engine temperature. Also your tstat controls how fast the water moves and you can also get a cobra water pump pulley unless thats part of what makes it a high flow pump. When the early C3's Big Blocks came out they had some cooling issues. In a non pressure system he likely lost fluid on the track or road. Discuss all of the aspects of cooling that you can think of! I'm sold on their products and would highly recommend installing one. A high volume water pump stops the engine getting hot spots where the coolant boils off the cylinder walls stopping them from being cooler as the coolant is no longer touching. I once had a 468 BB that I had problems keeping cool. Stay away from high-flow. Knock can also occur when the combustion of in the cylinder starts off correctly with spark plug ignition but one or more pockets of air/fuel mixture explode outside the envelope of the normal combustion front ignition. A sharp edge in the combustion chamber or on top of a piston.
The reality is any manufacturer can claim high flow rate and few make any effort to material change their product. Still have it on the shelf. Manage Preferences - Advertising - The radiator has good airflow at highway speed and hot air is being sucked out of the engine compartment. But you must remember that longer the time in the radiator, the longer the time in the engine where it can only absorb so much heat before the boiling off the cylinder walls. Cavitation is the formation of vapor bubbles in a flowing liquid where the pressure of the liquid falls below its vapor pressure. So Im hearing mixed results here. FFR#5327 MKIII delivered 03/12/06.
HF Centrifugal Pump Medium Flow The high efficiency and continuous duty capabilities make these pumps ideal for use in industrial applications. A forum community dedicated to Factory Five owners and enthusiasts. FlowKooler pumps flow more coolant through the system at low speed and simultaneously raise engine block pressure 22%. 1. Designing pumps to flow more helps.

Previously Bob T****r. Bob I've removed and reinstall my radiator on the completed car. When the vapor bubble that forms rapidly collapses it produces a destructive shock wave that damages the interior wall of the engine block and other components, causes vibrations and noise and results in a loss of flow efficiency. I figured now is the time to upgrade my waterpump. F Range Flanged High Flow Pumps The high efficiency and continuous duty capabilities make these pumps ideal for use in industrial applications. Spit the cover gasket out.
These big blocks like to run hot and Id love to get every advantage I can get to beat the heat. It makes sense; the engine is turning the water pump rapidly and sending coolant through the radiator. You would think so reading their web sites and catalog listings. ). From my own experience I have been through magic water wetter, lower thermostats and a water pump called flow-cooler through the years. Most engines keep cool at highway speed. They are ideal in applications such as water supply, irrigation, pressure boosting, feedingcleaning sets or firefighting sets, water circulation in air-conditioning units. Our range of high flow pumps are designed to be efficient and are capable of continuous duty. At low speed, it is a different story; engines tend to heat up when you face limited airflow, trapped airflow and slower moving coolant. FlowKooler introduced the first hi flow pumps to the aftermarket and continues to improve impeller design to this day. We even get request for bespoke impellers for industrial applications like gensets and oil field pumps.
Advertising - Runing a stock water pump. Of course engines stay cooler in these conditions.
Hopefully, you will debunk Grandpa's theory yourself before you experience vapor lock. I found under heavy load going up a long hill was were high flow helped a little. I'm trying to see if I can increase the volume of flow thru the heads without increasing the speed. Contact Us - No over heat problems here. This helps prevent their formation of a steam pockets and suppress es engine hot spots caused by them. Simply put, you have a far better chance of keeping your cool with a greater flow rate through your heat exchanger than gathering heat in your engine block. The early Hemi seems to cool well. Radiators, transmissions, electric fans, etc. The other consequence is an increases in cylinder pressure which can be harmless or destructive to rings piston or bearings. So Grandpa was on to something but just not for the reason most people think. Come join the discussion about performance, builds, modifications, reviews, engine swaps, classifieds, troubleshooting, maintenance, and more! Howard Stewart performed reaserch for both the OEM and his own business if I remember correctly snd the outcome was more flow and higher pressure always cools better. FlowKooler impellers are designed to tighten clearances to reduce "slop" in the casting chamber and build that system pressure. The fluid in your system transfers those electrons based principally on the source-sink differential and the exchange material's transfer rate. HF Centrifugal Pump High Flow The high efficiency and continuous duty capabilities make these pumps ideal for use in industrial applications. i had the 750 mach 111, and put the 250 emblems on it to bait stupid people.darn bike almost killed me a couple times. They can be used in commercial, agricultural or industrial applications where high flow rates are required. In a closed loop system if you keep the fluid in the heat exchanger you are simultaneously keeping it in the block longer. Most vehicles do not need to restrict flow because they do not reach or sustain high RPM. Come join the discussion about performance, racing, conversions, modifications, troubleshooting and drivetrain. Read our Privacy Policy for more info. Building 306 Donor, with GT40 ported Heads and Trickflow Stage 1 cam, T5, 3 link rearend with 3.55\'s, Gas n Go Sidepipes, I do know that the oil pump MUST be standard. If their brand is strong enough it just becomes accepted. St. Jude Donor '05-'06,'11,'13-'14,'16,'18,'19. "But wait a minute, I know Grandpa' used to put washers in his flathead to slow the flow and cool his engine." Consider that Grandpa had two flathead water pumps sending twice the volume through the same size radiator core. Your car will be fine with the FFR fan, stock rad and stock wp. It will cause the peak of the combustion process to occur outside of the optimum moment and results in a characteristic metallic "pinging" sound. In a small block, no difference at all. FlowKoolers impellers are precision machined from billet aluminum and designed to increase flow of the coolant. Cavitation occurs when a pump turns so fast that you generate lower pressure and air bubbles or vapor forms. At high rpm the coolant moves through the block fast enough to prevent any steam pockets from forming. Has anyone replaced just the waterpump with a high vol unit and noticed a signifigant change in cooling properties? you have to size the cooling system to the hp. I (mr Overkill would get a new 2 core rad or whatever cool aluminum one you want only because it really does not look easy enough to change . If the radiator is in decent condition and reasonably clean, the stock pump will work just fine. Impellers feature larger diameters, tighter vane-to-casting clearances, shrouding, porting and have incremental vanes. Higher Flow Rates Lower Engine Temperature. Had a bad core shift problem. Putting a "hi-flo" water pump with a stock radiator doesn't make a lot of sense. This restrictions makes sense when your rpm is excessive but it rarely makes sense normal driving conditions. High performance sbc stuff, turbo motor parts. Additionally, thin aluminum radiators already restrict by design e.g. M III recieved 8-06, 3 link,lca's PS+PB,carb,302,373 gears, T5 first start 8/27/06.Go Kart 9/9/06, I have a mild 347 stroker. 331 Stroker, TKO 600, IRS, MassFlo. It takes time for the Heat to transfer can not be rushed. Can u please expain to me how he's worng so I have a better understanding of the system. 2. This helps to prevent the onset of cavitation. If you see the same stamped steel or the same casting in all of them then you have your answer. At idle our pumps pump more than twice other pumps and we outflow performance pumps by 20%. Whatever you call it, FlowKooler pumps are 32% more efficient than OEMs which means less horsepower is used to turn them. It's solid physics, more flow better cooling. FlowKooler pumps take the coolant out of the engine and put it in the heat exchanger or radiator to get it out of your system and keep you cool. Causes include: Flowkooler hi flow pumps help reduce engine temperatures and stop the after run or pinging characteristic of a pre-ignition condition. Because FlowKooler pumps reduce engine temperatures as much as 30 degrees, they are frequently recommended by aluminum radiator manufacturers as a necessary tool of cooling for hot engines with thin radiator cores and reduced capacity. Rapidly spinning the impeller can literally rip the air from water but may not actually move the fluid, it's tantamount to turning an eggbeater in a paint bucket. We know people did this too. Not racey.. Just a really nice rebuilt 302. The water has to have time to cool argument is most common one we hear. Archive - Higher Block Pressure Prevents Early Cavitation. Do Not Sell My Personal Information -, By logging into your account, you agree to our, Help finding a switchable "keyed on" power source for my new fan, The following errors occurred with your submission.

Also what do I do about my cap? Terms of Service - Increasing the block pressure by as much as 22%helps reduces hot spots on cylinder walls, prevents the formation of steam pockets in the engine block and prevents the cavitation of the impeller. If we have 200 going in then we would like to see 170 coming out. I want to replace the old worn water pump on my car now with a real good one that can put up with parkinglot highways of NYC During the summer. Location: I tend to be leery of any guy who doesn't own a chainsaw or a handgun. Contact Us - No. I'll say thst a high flow pump will not resolve other issues that hsve nothing to do with flow. FFR aluminum radiator on a moded 302. Copyright 1995-2021 The Jalopy Journal: Steal our stuff, we'll kick your teeth in. In the extreme, steam pockets can lead to detonation (hot spots in the cylinder wall) and detonation leads to broken parts. I believe the design of a turbine impeller ,like that of a elderbrock water pump leads to less cavitation .with vettes it helps to bleed all the air out of the coolant system.I use a thermostat housing with a radiator cap on it ,to bleed all air out . A poorly designed water pump casting and impeller can result in wasted horsepower. Some refer to the improvement in flow efficiency as a gain in horsepower, other call it a conservation of horsepower. I put a Stewart Components High Flow water pump on it and it helped considerably. My current cooling system is working adequately, but if I can run cooler with a high volume water pump then Ill do it. Terms of Service - The Fora platform includes forum software by XenForo, VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Higher Block Pressure Prevents a Vapor Barrier When you send a higher volume of fluid through a fixed diameter e.g. Far faster than the flow rate of the water pump. Whether it is in stop and go traffic, a slow moving parade, in line at a car show, off road on the trails or hauling a heavy load up a grade, cars and trucks experience reduced airflow through the radiator due to slower speeds. PERFORMANCE RANGE Flow rate up to 2200 l/min. About Us - Sending hot coolant from your source (engine) through the heat exchanger (radiator) to the sink (air) will transfer heat as long as there is a temperature difference between the source and sink. For a better experience, please enable JavaScript in your browser before proceeding. I believe they do, the BB has a flow imbslance also (more water flow to one head) that with the correct pump can be resolved. If you doubt this thinking then try this simple Ask Dr. Science experiment where you restrict the pump on the suction side; just clamp off the lower hose while you watch your temp gauge. When you face Grandpa on the track you may want your washers, otherwise, keep them in the toolkit. Nope, the stock pumps work the best.Speed joints propaganda and hype. FlowKooler has sold pumps to muscle car owners, street rodders, off road rock crawlers, people towing RVs and horse trailers, boat owners and even Propane powered trucks! These conditions exist in stop-and-go traffic, at car shows, rock crawling or off-road or in any vehicle under a load. I agree to receive emails from the site. To Do high flow water pumps offer any real benefit? FlowKooler hi flow water pumps incremental vanes carve up the workload and conserve as much as 2.2% horsepower. JavaScript is disabled.
No cooling problems, the aluminum eliminates a few pounds and the low flow saves a HP or two. You'll be fine with the stock pump and probably the rad too . The only time I would try to increase flow is if You have more than 40 degs and the Engine running Hot.
Cookie Policy - "Waterless Coolant" ??? The following errors occurred with your submission, CorvetteForum - Chevrolet Corvette Forum Discussion, V8 Technical Info, Internal Engine, External Engine, Basic Tech and Maintenance for the C3 Corvette. We hear that the coolant has to stay in the system longer to cool but what is heat transfer really but conduction, convection and radiation of electrons. Hot spots can damage to the point they actual burn holes right through the top of pistons. Knock, detonation or pingcall it what you want - it is a problem.
I have the Ford racing Pump on the 408 With Gordons rad and it's really gooD .However, in all (more than 10) 5.0 cars ranging from the bone stock to blown 306 to a T bird 5.0 auto with a cam I've always New oe pumps and to date even on 100* days flat out in the blown mustang never had an overheating problem.
