There are many more new products in addition to those listed here:
The triple layer windage tray kit below is mounted to a scraper for the 2.2 Callies stroker crank (pan baffles with trap doors included bu not shown). The kit below is designed to work with the stock steel and alloy pans. We also make dual scrapers that will work with pans from Canton, Moroso or any sort of dry sump pan. We supply modified windage tray inserts for the Moroso pan.
Many thanks to Brad Melkis for making this video.
Our windage control items helped with the top performing LS engine in the 2013 Amsoil Engine Masters Challenge. http://www.popularhotrodding.com/enginemasters/1309_2013_amsoil_engine_masters_challenge_friday_coverage/viewall.html
Many customers have asked to purchase some of the fine directional steel screening that we use for many of our windage tray products. This is now available in a 20" by 24" piece (the 20" dimension needs to be parallel to the crankshaft) for $49.95. This is probably enough for two pans. The product is shipped rolled and shipping weight is 3 lb.
We have improved the Dodge SRT4 dual scraper and triple layer windage tray set once again! Now the kit is ready for aftermarket strap kits, if desired. Special seals for the oil pan pump passages are now provided.
We have improved the Mopar big block windage tray assembly once again! The optional final counterweight surge baffle is now to work in unison with an extensively modified Milodon 32000 windage tray and custom scraper. The kit below is designed to work with a stock steel pan.
Custom windage tray, crank scraper, pan baffles and pickup tube for Dodge 2.4
The customer supplied a custom fabricated steel pan
An anti-surge baffle with venting and integrated dipstick guide tube was installed as well as a longitudinal baffle with dual trap doors
A standard "Eclipse" type pickup tube was sectioned and positioned closer to the pan floor to increase the G-rating of the sump as well as to allow the Mopar anti-vortex dimples to function properly. The tube was reinforced with two straps.
The windage tray assembly was modified in a number of ways to fit the interior of the pan. A dipstick guide was included that works in tandem with the guide present in the pan.
Many thanks to Pete Exton for his extraordinary help with this design.
SBC scraper for late LT1 -- thick steel to use with sectioned one piece gasket (Fel-Pro shown); can be used with two or four bolt mains. Also available without dipstick hole and with different strokes.
BMW M30 dry sump
BMW S14 updated design
The scraper pictured below is an update of our S14 Teflon design (in this case for a knife-edged crank)
Steel and Teflon bladed scrapers for the Brian Crower KA24 stroker crankshaft
Steel and Teflon bladed crank scrapers for the Nissan CA18DE and CA18DET
Studebaker V8 windage tray with adjustable louvers and directional screening; this is a copy of the factory R series tray but with louvers and screening added -- it is welded into the stock pan.
Studebaker V8 crank scraper available in steel and Teflon bladed versions for the 289 and 259
Circle track modifications for the Dodge 2.4
Toyota 4AGE 20V
Modified factory 4AGE tray -- directional screening is added to the interior to dissipate the energy of high speed oil droplets. The border and tray is sectioned to match the 20v oil pan rail and drainage is added. A 20v Teflon bladed scraper is also shown that works in harmony with the scraper. The scraper is for a custom crankshaft that has been knife-edged.
AMC Straight Six 4.0, 258, 232 update
Directional screening downstroke panels
Chrysler Slant Six
Updated based on our successful design for the BMW M20 and M30 slant six
Directional screening windage tray for 4.6 Rover with steel pan (enquire about similar trays for earlier engines). The tray attaches to separately available dual scrapers.
Modified Milodon Windage Tray for Ford FE
The windage tray has drain ports added and an interior layer of directional screening making it a dual layer tray. The modifications vary depending on the block style and type of crank scraper it is working in harmony with.
Modified Milodon Windage Tray for Mopar B, RB
A special scraper design works with it to allow oil to pass beneath the tray on the downstroke
GM LS Engine
There are scrapers and modified stock windage trays available.
The tray shown is GM part number 12558189 which is the full length one. There are multiple stock patterns that the same general modifications can be performed on.
The principal aims were to introduce a small amount of additional order to the windage flow and to extract more entrained oil from the cloud. A divider was used in the center to encourage the flow pattern to circulate in bays 1-2 and 3-4 rather than simply have chaotic flow over the third main. The louvers were extended inward on the downstroke side and then had this element transition into directional screening on the floor. This screening rises above the lowest louver on the opposite side of the tray. This transforms the lowest louver openings into drains (additional drain holes drilled as well). However, because of the orientation of the screening openings (iterated small louvers) the total amount of "louvered" area is greatly increased. The screening helps prevent oil from bouncing back up after striking the interior tray surface and protects oil that has passed through it and is then flowing out of the tray.
The uppermost upstroke louvers have been opened up a bit and the scraper serves as a new and far closer edge to guide stripped oil into those openings and also to reach in and disrupt the pressure differential of the windage cloud. The scraper moves the windage tray approximately 1.5mm closer to the floor of the pan.
Overall, this is an enhancement of the original design going beyond what is possible with a single stamped piece of metal.
It is thought that the destruction of these engines at high G's is mostly due to oil migrating into the rotating assembly and being trapped by the windage tray and the network of passages through and over the mains/webbing. It becomes churned full of air before being ejected and this increased aeration is what kills the bearings. Entrained air requires more time to be released than simple foaming on the surface. The scraper and modified tray helps to more quickly extract this oil while still allowing pumping exchanges between cylinders and bays.
The scraper and tray can be used independently of one another if desired. Stroker and Teflon bladed versions of the scraper are available.
Important note: If you want a tray to be modified for use in a stroker engine you must fit the stock one to your rotating assembly and then send it to us.
A racer in Canada recently requested a dual Teflon scraper and windage tray for his Volvo B20 engine. The windage tray design was adjusted from a previous version to accommodate the drain ports on the downstroke side of the block. The windage tray is designed to work with or without the scraper and is set up to be used on the B20, B21, B23, B230 and similar engines. Provisions are present for two different dipstick locations.

Crank scraper for the Nissan RB26DETT engine
One of our customers was kind enough to ship us a block to enable us to design this product. For clarity, the stock windage trays normally covering the girdle have been removed as well as the pickup tube. We also have a pattern for the RB25.
Modified windage tray for the Moroso alloy pan for the Toyota 1ZZ and 2ZZ engine
Above and below: the stock insert shape has a layer of suspended directional screening to dissipate the energy of high speed oil droplets expelled and/or stripped from the rotating assembly. It is shown positioned over our crank scraper pattern for these two engines.
Mazda BP Teflon scraper and modified tray
When we first made scrapers for the Mazda Miata 1.8 they were positioned along the pan rail. They are now located along the main bearing caps. A racer contacted us who had engine blocks and pans that were specially machined to accept this earlier design. In support of our customer, we designed a Teflon bladed version, furthermore for a knife-edged crankshaft. In addition to wanting a Teflon bladed scraper he wanted us to add directional screening to the interior of his stock windage tray.
This design is certainly effective and we moved away from it only because it required some adjustments in order to achieve good mating between the transmission bellhousing and oil pan. The new design along the main caps has been in place on cars winning national SCCA championships. This older -- but supported --design should be strongly considered if you are using aftermarket main bearing caps or modified OEM ones.
