Default Improved Racing Crank Scrapers

Improved Racing has just released a line of crank scrapers for LS engines.

Improved Racing's crank scrapers help reduce oil starvation by closely contouring the crankshaft to remove off excess oil, ensuring more oil makes it to the bottom of the sump. Crank scrapers also help reduce parasitic drag and windage losses caused by excess oil on the crank, resulting in a typical horsepower gain of 2-4 horsepower at the wheels.

The crank scrapers are designed to work in conjunction with the factory windage tray.

We currently have two versions available:

EGM-300 - $73 - For F-Body oil pan and windage tray (fits factory 3.622" stroke only). This version provides extra windage control below the first two cylinders to make up for the shorter F-Body windage tray, which doesn't cover the first two cylinders.

EGM-301 - $69 - Universal crank scraper for all factory 3.622" stroke LS and Vortec V8's

If you have a stroker motor or aftermarket crank and rods, you may still be able to use our crank scraper but you may have to file away some material to make sure everything clears properly.

Check them out here: http://www.improvedracing.com/oiling...rs-c-3_50.html

Seeing that these are being used with the stock main bolts, It's safe to say they would have to be drilled to fit onto an ARP main stud?

Yes, they probably would. But we are going to add holes for the inboard studs in the next batch we make.

Yeah, we are working on a 4" stroke scraper and hopefully it will fit all common setups, but that remains to be seen.

I agree but I wonder if it actually does more than just look cool. I ordered one of their baffle/trap door setup and saw they made this.

I am planning to order their baffle/trap door setup and was wondering what the install of these crank scrapers would consist of. My plan is to drop the K member while supporting the engine up top and if it is easy enough to install one of these while I am doing the baffle I would like to go for it. Any chance we can get a group buy going Improved Racing??

The crank scraper install is very easy once you have the pan off. It's just a matter of unbolting the windage tray, then installing the crank scraper with the windage tray bolted back on on over it. A link to the instruction manual is on this page: http://www.improvedracing.com/manuals.php

So if you have the pan off the car, it's highly recommended to install the crank scraper to optimize oil control and gain an easy 2-4 RWHP.

NOTE: Our current crank scrapers only fit the factory stroke, but we are working on versions for strokers (4.0" is next).

It will probably still be a while; we're still trying to collect cranks and rods from several aftermarket companies so we can make sure it will fit most stroker setups.

I installed the windage tray and trap door setup in my engine last week. That combined with the factory windage tray, i think think any parasitic loss and oil control problems should be taken care of.

One question I do have is, will oil be able to work it's way down to the pick up quick enough with the trap door system? There are only a few vent opening on the top.

I am using the scraper and baffel on my setup, solved my starvation problem during track play, dropping the K to install was a pain but worth it.

Yes, in fact it has much better drain-back performance than the factory baffle. Our baffles have louvers to help trap windage oil, drain-back guides to direct oil on top of the baffle to the pickup box, and drain-back slots to accelerate return of oil to the bottom of the sump. The factory baffle is basically a flat piece of steel with none of these features.

Awesome, glad it solved your issues! Thanks for the feedback. With this setup you'll be good to about 1.4 sustained lateral G's.

I have a Darton Sleeved LS6 447cu.in. with a 4.125 crank. I bought the LSX Windage Tray Kit (P/N 19202609) from GM Performance Parts that is for a 4.125 stroke crank.

Does your piece fit under the tray and will I have to grind in key areas to make it fit? What is made of and can I use a simple dremmel tool for the job?

Yes, it sandwiches between the main cap studs and the windage tray. With that stroke you'll have to remove quite a bit of material to make it clear. I'm not sure how well that will work so I wouldn't recommend it. The crank scraper is made from steel. You could use a dremmel but it will take some work.
