Crank Scraper / Oil Pan Baffle

[Site]

Check this out:
Honda Crank Scraper

This is the first time I've heard of a "crank scraper". The theory makes a bit of sense.

They will make a free one for our engine for the first person who lets them use their car to develop a pattern. May be worth a shot, since it would be free. I'd like to see before/after track times.

Here's some info from their website:

Even if you use light oil, surprising power gains can be made by keeping oil away from the rotating parts in the crankcase. Crank scrapers are easily fabricated for any engine, and so are custom oil pans using billet pan rails.

It basically has to do with keeping oil off the crankshaft. … If you lighten the crankshaft itself up, from a rotational standpoint, … that car will move from point A to point B faster. It won’t show up as dyno power, but it will show up on the stopwatch.

But in any event, assume that oil passing by the crankshaft and pulses of air created by rapidly descending pistons and the volume of air entrapped up inside them will combine to increase the importance of reducing the amount of oil that becomes a “passenger” at high crank rpm.

I am going to raise the suspicion flage here. That is basically what a windage tray is.

[Dibbs]

I've heard of oil wipers before. Never worked with one before though.

[Justin86]

Something new. Well if it is free then what the hell might as well try it.

i would have to say it is BS.
honda spent hours and hours trying to figure out what is the best way to keep the oil sirculating, and this company comes along and tells us this would honda extra HP.
It is BS.

[AccordEpicenter]

Nope its not bs but the gains are minimal at best... The scraper does not actually touch the rotating parts, it just kinda wipes the excess oil away from the crank, gets rid of some parasitic loss. I think somebody should try em

[guaynabo89]

Not a new product. been around for awhile. Gains would be minimal at best, but when your trying to get every little bit it might help.

[2old_honda]

the new neon SRT-4 uses that same thing. little tabs that extend from the pan gasket.

[k-roy]

I have done some reasearch and they do sound like a decent idea if you want to run an all out engine. The more oil in the pan the better. I think a windage tray in conjunction with a scraper would be the best setup. That way little oil would splash around and stick to the crank. Also the oil pump pickup will always be submersed in oil, regardless of how many lateral G's you would pull.

I just found this: http://www.jegs.com/cgi-bin/ncommerc...74&prmenbr=361
I thought I had seen something like that before. I guess it is a valid product. Anyone willing to donate a block, crank and pan for testing should do so. It sounds like a worthy upgrade for $50, even though all those chevy guys can get them for 1/4 that price. Dam those Chevy V8s, you can get ten differant types of everything for them for mad cheap.

Your argument is based on the completely invalid assumption that they would engineer everything about the car for the maximum performance. If Honda's engineering is so great that it can not be improved upon, why have people shown gains with any other aftermarket parts? And the claim is not more power, it's power available earlier which is the case with any mod with the purpose of lightening the rotational mass.

[Vinny]

wonder how long they's need the engine for, I m,ay just email them for shits and grins. Tampa's not too far and I do have a spare motor in the garage

[k-roy]

Hell yea Vinny. Its free so you might as well go for it. I'll buy one if it works out.

seems that this company did make them for us... i'm thinkin about that teflon scraper...

yeah, from the dead as they say... better than a new thread, though

[Cheeseburger]

cool find bro!!!!

[EricW]

I'm buying the teflon one with the baffles and the baffle for the oil pan i just have to send them the money.

[HondaBoy]

you know, this looks so easy to install. i've taken the oil pan off before and wondered about making a baffle of some sort for it because going around a corner really hard has made oil pressure drop and my oil light come on. anyway, that looks great and i think i'm going to buy that sometime soon.

[mkymonkey]

ok...again me with my newbie questions...


what are the purposes of these items???

[shepherd79]

interesting, but will this really help?

[A20A1]

Awesome.

[EricW]

I just sent the money so hopefully i will have them with in the next week.

I've had problems also with the oil sloshing away form the pic up and the oil light coming on, I hope the oil pan baffle will cure the problem.

[EricW]

what are the purposes of these items???

The scraper removes excess oil from the crank, the oil is extra rotational mass, and the baffles keep the oil form moving away form the oil pickup.
There's a better explanation on the companies home page towards the middle http://www.crank-scrapers.com/

[lostforawhile]

great find,finally a useful item for our engines,yea i have the same problem with sloshing oil,I was going to install an accumulator tank but this might fix the problem.

[bobafett]

wow thats a really good find! i had my oil pan modified and baffled, but the crank scraper would be really cool. i doubt it fits with LS rods though. might be cool to investigate though... the price is certainly right..

[wprocomp]

sweet! man I am gonna order me the scraper and the baffle too

[Strugglebucket]

so the baffle has to be welded to the pan?
