Crank Scraper.

Has anyone heard of these before?

This is an ISHIHARA-JOHNSON oil- or crank-scraper for the Honda D16 1590cc 90mm stroke (1.6L) engine (such as the D16A6, D16Z6, D16Y7, D16Y8, etc. – do not confuse this engine with the B16 1.6L which has 1595cc and a 77.4mm stroke).

As the engine rotates, engine oil is not thrown off but instead sucked into a tornadic windage cloud around the crank and rods: the horsepower that is required to move and move through that oil is significant. The scraper strips away that cloud by coming close to – but not touching – the spinning crank and connecting rods and this frees up that internally consumed horsepower. Remember that as you accelerate, brake, go up and down hills, and turn your vehicle even more oil is whipped up and power lost; stock engine output is determined from a static test so the scraper will help restore that lost power ASAP! In highly tuned engines, too much oil splashed on the cylinder walls can overwhelm the piston rings and thereby be introduced to the air/fuel charge. This contamination will lower the effective octane rating of the fuel and can lead to detonation. Lastly, a crank scraper can improve your fuel efficiency. (If you can resist the urge to put the pedal to the metal!) This is well-proven technology that has been used with great success in small and large displacement high-performance street and racing engines for decades. The windage tray incorporated in the stock Honda oil pan should not be confused with a crank scraper.

Installation instructions are included. The scraper simply bolts in place in between the block and oil pan. The next time you change your oil, simply drop the pan and install the scraper. You need to buy one pan gasket and a tube of good quality RTV silicone gasket maker to apply to the scraper. The scraper is constructed from 12 gauge mild steel (approximately .10”). Some minor clearancing might be required which can be accomplished with a simple hand tool like a good metal file (the mild steel is easy to work with).

WOW, that looks so kick ass, i'm asuming that you are getting this Kris, so please be sure to tell me how it all works out!!!

Well, I have never heard of them. But I really dont want to run out and buy something that "sounds awsome". But any little bit can help. I was just curious to know if they work, and are effective. We all know the tornado sounds like it produces 100hp + :D

I wish I was still in high school when I was taken metal & machine shop... I could make that stuff for next to nothing & test all kinds of stuff without spending all the dough.

So no one has ever seen or heard anything about these??? Damn i could put one in, i still have my motor apart for a few weeks yet..... waiting on my damn 20 over pistons..........

I wouldn't put one in. If they were such a great thing than they would be appering in other places rather than EBAY, they would be in like spoon and skunk2 catalogs.

Thats true, i see what ur getting at, but what if this is new and like OMG the best thing that happened kinda thing?

Than i would wait till a well known company made one and buy it from them. I don't know about you but, I don't want a cheap piece of metal down by my crank, and having it break.

Thats very true, and 100% the reason why i wont buy one yet :D

Talked to one of the guys at work that races alot, it couldnt hurt to use it...but your not gonna see a noticable difference in our cars. So unless your building a race only car, like looking for 150,180,etc...mile per hour speeds you wont see much gains from it....... hope this helps everyone.......

If there cheap enough, ill be the test bed and install one. Just tell me how much they are and where you saw them at.....

Yes, I've heard of them. You don't see them on many "real" racing engines (I'm not talking about drag motors) as they usually go with a dry sump setup if allowed to.

Yeah - heard of them being used on big block street motors and the like, but not on race cars. I seriously doubt you would see ANY difference in power output etc though in a stock or mildly modded Honda engine - trust the engineers, they know what they were doing when they designed the engines :)

Easier to spend the money on some VTEC stickers, that way everyone will KNOW it goes fast :p

So what does one cost anyway???

about $60

Ya know what is funny about this, is that guy started making those because of me. He has many other applications including for the toyota 4age which I own, I asked him if he had any for the d16, and he said he would try to pick up a block and a week later bam! they are here. I havent installed my 4age scraper, but I cant wait to it just lessens the strain on rotational mass, his scrapers are good quality, but could be made for 5 bucks if ya knew what you were doing.
