banshee_kid350 Posted April 7, 2004 Report Share Posted April 7, 2004 My banshee would get really hot at the dunes the pipes coming out of the exhaust ports would be bright red at night when I go up sand mountain and sometimes it would spit antifreeze out of the over flow. So im going to add a noss head and thinking about an impeller from pro design do you guys think that would help??? would some different coolant maybe help also?? also I heard that those pro design impellers cost horse power is that true?

jrm312 Posted April 7, 2004 Report Share Posted April 7, 2004 id say your your runnung lean, and yes the propeller will help cool it better and the noss head is great i love it tons of power and i havent over heated yet. Quote Link to comment Share on other sites More sharing options...
ranshee Posted April 7, 2004 Report Share Posted April 7, 2004 Sounds like you need to play with that jetting first. Your pipes should definitly not be glowing bright red, especially at night. Quote Link to comment Share on other sites More sharing options...
Brian G Posted April 7, 2004 Report Share Posted April 7, 2004 The pro design impeller just robs horsepower, just use the stock one!! and fix the jetting on the bike. Quote Link to comment Share on other sites More sharing options...
wansomordis Posted April 7, 2004 Report Share Posted April 7, 2004 The pro design impeller just robs horsepower, just use the stock one!! and fix the jetting on the bike. I'd have to disagree.. A stock one will get so hot that it can break fins off of it..Also any type of plastic when heated will flex resulting in less cooling which isn't a good thing. Even if ia pro-design causes a slight loss of horsepower do you think running HOT makes more ???????pro-design is the way to go and also prolongs engine life Quote Link to comment Share on other sites More sharing options...
sredish Posted April 7, 2004 Report Share Posted April 7, 2004 At the very least, I'd replace the stock impeller just for the fact that it's a plastic hunk of waste that can break at any given moment. If your worried about losing hp, however little it may be, you can cut a fin or two off of the PD impeller. Also, for overheating, run Engine Ice coolant, it will let your motor run quite a bit cooler than with standard antifreeze. You can get it at RockyMountainATV.com, just type it in the search. As far as your pipes getting red, that sounds like a jetting condition, your pipes shouldn't be glowing like that. Get your jetting squared away, replace the impeller and replace with Engine Ice, and your overheating worries are gone. Quote Link to comment Share on other sites More sharing options...
nater006 Posted April 7, 2004 Report Share Posted April 7, 2004 Definitely a fan of the PD impeller, here. My last shee ('91) broke all the fins off the stock impeller. Piece of junk. I put a PD in and never looked back. Don't think it really robs much power.. it wasn't even noticeable on that one. Quote Link to comment Share on other sites More sharing options...
Blacksmith Posted April 7, 2004 Report Share Posted April 7, 2004 The PD impeller is a soft POS that will cut out under the seal lip and leak in a very short time compaired to stock. I know, had it happen. As such, I would not replace the stock one with a PD. I might however buy a new stock one and for sure would buy a new drive gear. If you are making that much heat then I'll bet you have melted at least a slot in the back of the one you have. I would put a noss head on the bike, but the most important thing I would do is jet up at least a couple of sizes. Good Luck Quote Link to comment Share on other sites More sharing options...
Brian G Posted April 7, 2004 Report Share Posted April 7, 2004 Do not use the PD impeller, it puts serious load on the drive gear and actually it cools worse than the stock one, The only way to make it work better is by taking 2 fins off of it, grind them down!! I know the stock one is plastic but when its maintained properly it will not fail. correct jetting, good coolant and no play in the mounting are all factors in the life of the stock impeller and if you dont believe it robs power, put it on a dyno. I couldnt believe it myself but it does. Quote Link to comment Share on other sites More sharing options...
nater006 Posted April 7, 2004 Report Share Posted April 7, 2004 How much power does it rob? I'd be good to see some dyno figures. I'd give up a little HP for increased cooling and a reliable impeller but that's just me.. just wondering how much HP it really takes though.

350duner Posted April 7, 2004 Report Share Posted April 7, 2004 If you are running that hot and your stock impeller is functioning (are you sure coolant is circulating?) then your problem lies elsewhere. The coolant circulating in the motor doesn't cool the combustion process, it just keeps the top end from overheating. If the pipe is red then you are running way lean. When was the last time you did a plug chop? How does the PD impeller rob horsepower? I've never heard of this. It circulates coolant slower so it doesn't seem like it should cost any more hp than stock. I'm planning on getting one because I don't want the stock one to break on me during a weekend of riding. If I get one soon I'll put the temp gun on the bike before and after and see if it makes the difference they claim. Quote Link to comment Share on other sites More sharing options...
banshee_kid350 Posted April 8, 2004 Author Report Share Posted April 8, 2004 well im running 330 main jets.Do you guys think that I should maybe drop the clip on the needle jet and richen that??? does anyone know what the stock neddle jet click is soppose to be set at??

hamuel Posted April 11, 2004 Report Share Posted April 11, 2004 Just out of wonder how does it robe power???? more drag?? More weight??? COme on explain. Logic dictats. it's cools better. For one is's like 5-10 grams lighter. as a whole mass. it also wieghts more in the fins. Which means it spinn's a little faster and keeps going with LESS load on driver gear. Things in motion tend to say in motion. Then again if im right does pro impler have a closed fin's?? which means the water it does start to move goes where it should?? Stock it can just go to the center of the impler and do nothing. Shrug WHat would i know Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted April 11, 2004 Report Share Posted April 11, 2004 (edited) The PD water impeller slows the colant flow down for a more even less agitated flow. The PD need to be broken in before it will work at it's best. With the coolent flowing slower and smoother, it will soak up more heat from the cylinders and cool off better in the radiator. It works like they claim and I have no complaints..except for a buzzing noise from my water pump. But I have yet to overheat since I installed it and if your wondering about power loss..it's negligable..I pull holeshots on 250r's. Oh my PD impellar is over 3 years old so it's pretty reliable as well. It will rob power because it rubs on the water pump housing. Once it's broken in..I.E. wears to the housing..it'll be good for years to come. Edited April 11, 2004 by MotulMonsta Quote Link to comment Share on other sites More sharing options...
