crank scraper

what do you people think of crank scrapers, any one ever used them,
for the people that don't know what they are:
Crank scrapers are a very inexpensive and simple -- but effective -- way to improve the performance of your engine! A crank scraper is a piece of metal that disrupts the oil-filled windage cloud that forms around the spinning crankshaft and rods. The scraper actively removes excess oil from that cloud and returns it to the pan. Crank scrapers have been in use for at least 40 years and are considered to be a well proven technology by professional automotive engineers. Scrapers come in a number of different designs and are present in many stock engines. Yes, they really do work. In the mid-1980s Chrysler and Mobil Oil did joint research on the windage losses for the 2.2 engine in the Shelby Charger. After designing and installing a crank scraper type windage tray they recovered 7 hp at 6000 rpm and 9 hp when using Mobil-1 synthetic oil. Ishihara-Johnson crank scrapers are constructed from 12 gauge mild steel (about .10” or 2.5mm thick) and include installation instructions. The scrapers are installed between the oil pan and engine block or along the main bearing caps.
WHAT ARE THE BENEFITS?
Less rotating mass for the engine to accelerate due to removed oil
Less loss of power due to excessive drag caused by the windage cloud
Helps avoid oil starvation by keeping the oil in the pan during hard braking and turning as well as off-road driving
Helps cool critical engine parts by quickly returning heated oil to the sump
Helps prevent the cylinder walls from being overloaded with oil
Can help with fuel efficiency
i think our 1.6 could get make 5 hp from this mod

If you want to waste the time taking everything off for those low if any performance gains. It kinda sounds like a waste of time to me, but what the hell do i know.

It's just a windage tray. They mount like a gasket between the oil pan and the block.
I've never used one, but from what I can understand... the effect would be similar to that of a lightweight flywheel. Just allows the engine to rotate more easily. Gaining and losing RPMs quicker.
I never much liked the effect lightweight flywheels have, though... they just don't seem to go anywhere at launch!
This mod would be more of a "finishing" mod. To balance out major work, along with a baffled pan, final ECU tuning... exhaust and intake tweaks... the list goes on.

Cheap easy quick mod. What do you mean remove everything? Have you looked at our engine. the oil pan can come off in like 5 mins

calm down, i have only taken oil pans off of 4wd trucks and i know that they are a pain in the ass. I haven't looked under an aveo engine.

a little excess oil could reduce hp by 5? I didnt think something so light sould affect the engine by so much.

SAm i am with Denis on this one, if you dont have something to add about the Topic dont post!
Oh and this is a bad idea, the engine crank needs a specific ammount of oil to operate correctly!

thats why i said "i think" and i did not just make up a number, 2.2 l engine make 7 HP and 9hp with synthetic oil.
so 7 devide by 2.2 and times 1.6 and you will get 5.0909090......HP, and if a person would use synthetic oil, 9 devide by 2.2 times times 1.6 and you will get 6.545454545.....HP

u cant go by that thou u dont kno how much hp that 2.2L was putting out....engines with the same amount liters dont always put out the same amount of hp. for example honda's 1.6 puts out more hp than our 1.6 (pretty sure. saw it on a website) say for example one 2.2L puts out 200hp and another puts out 185hp, now getting 7 out of each is gonna give u a dif percentage of the total hp.

I don't think it really "takes oil away" rather it keeps oil from being kicked up out of the pan. From my understanding the crank just needs to be coated with oil, and doesn't need to be soaking in it...
as for denis', or anyone's, numbers... they are irrelivant. There's more to performance than numbers. It's about fun!

Lets remember that was a shelby 2.2, so you should "rethink" those numbers, it will work out to about .08hp at the wheels

2.2 made close to 142 hp, so we still should be able to make 5-6 hp, and i almost forgot, the scraper will make the crankshaft lighter, so it would be able to spin faster, so aveo would rev faster, and get better acceleration.

how does adding a peice of metal between the oil pan remove weight from the crankshaft?
do you think before you make posts very often?

Time for me to step in. This technology has been proven. it is used on alot of race cars. So all the nay sayers. Just shut up! I'm really getting tired of the b i t c h i n g on here. Yes like a bunch of little kids. It would be nice if we could find a company to make one for ethe Aveo.

probably helps most on high revving motors. Most race cars are high revving so using one would make sense.

Hi,
I believe one of your forum members wrote to me asking if I could make a scraper for your engine. Yes, I could if someone in Florida could lend me a short block with pan. Blown is usually OK.
As for whether they work. Yes they do and it is one of the most proven technologies out there and been in use for at least 40 years. It comes in different forms, though, so you might not recognize it. Many OEMs use the tech in various of their engines. Off the top of my head: VW, Porsche, BMW, DaimlerChrysler, Cadillac, Chevy, GM, Pontiac, Mazda, Ford, Toyota, Honda, Nissan, etc.
If they work so great why aren't they on every engine? Good question. On another forum one of the writers was from Ford and was one of the people that did dyno studies on windage in the Mod V8. They came up with a scraper windage tray design that returned 4 out of 5 quarts to the pan cleanly (no foaming) during engine operation. It was not used -- why? Too expensive. I believe the Ford Cobras ended up using an aftermarket oil pan.
The percentage gains we have seen on the dyno for NA engines are in the 2-3% region for an engine that isn't even moving around. That is significant for a bolt on part that just sits there.
Please contact me if you can help out with an engine for a pattern. Thanks!
Kind regards,
Kevin Johnson

We need an engine that has been removed from the car.
I know that is not an easy thing to ask for a fairly new line of cars/engines.

I'm sticking with the 1.6. Plus 2004Aveo said that they are getting 150 hp 130 to the wheels right now. Thats the same power as the 2.0

yea and then ur done unless u turbo, but with a 2.0L u cant get more or even with a 2.3L from an aerio...i mean these cars are getting just about the same gas mileage but they have more hp....so since ur not gonna do the swap im gonna start doing my homework on my own swap...and i think might end up spending more money on the upgrades then a motorswap and then when u run out of options to get more hp out of the 1.6L ud be able to get more power out of the 2.0L/2.3L.....no replacement for displacement.

you still dont get it do you.....ok so turbo the 1.6L but it still wont beat a turboed 2.3L! if u turbo the aveo 1.6L u get the stock numbers for a 2.3L....its simple reasoning people...example you take ur 1.6L as far as u can and ill take my 2.3L as far as i can and ill bet you ill have more hp/lb plus the 2.3L has excently torque

like the only reason i am saying this is becuz i dont wanna put all this money into the 1.6L when i can get a 2.3L that will provide a surplus of hp....im just looking for something unique and something people wont expect when i pull up next to them

yea well i want the 2.3L from the aerio before anything because i want to be the first to do it in the U.S. since Brian has decided to stay with the inferior 1.6L lol...but im gonna put alot of hw into it before i do it....and when i find parts such as a cheap 2.3L aerio engine and tranny ill be sure to buy them quickly just to put away and study it...becuz i wanna own one of the fastest aveos(my personal goal, and its most likely gonna happen ) i also want to have a sleeper type car, since last time i check people laugh at racing an aveo (not trying to be a downer but thats wat happens)

Have fun mounting up that non GM engine in the car, and mating it to a GM tranny. or if you use the Aerio tranny, good luck getting custom axles made, and lining it all up. Buy a 2.0 from a Forenza.

i could but it seems like the aerio engine is getting more aftermarket support and i was gonna try for the 2.3L...and i know its gonna take work like that but thats the price you have to pay for more hp

yeah but think about it if like 40 members on the board chipped in like say 25$ a peice we'd have enough to win it plus get it shipped and then maybe we could get like a group buy discount when it's made just a thought but it seems as though the majority of the people on this board just enjoy Cajun Fooding at one another and trying to disprove one another now there are the few exceptional people on this board who are helpful but oh well like someone said earlier in this thread another mod gone to waste
