BMC dual windage tray



New dyno feedback from a tuner in Russia on the Teflon scraper by itself installed in a Toyota 3S-GTE: 

"Dyno test shown the gain of 1.9% hps, the increase displays in the diapasonum [interval or range] from 4430 to 8200 rpm."  "Also I see the more consequent oil supply in the head - my pressure sensors in the oil channels of the cylinder head now shows 2.2 bars instead of of 1.9 before while engine works at the mid-range.  [31.9 psi from 27.6 psi]"



Toyota 7M Teflon bladed dual scraper set -- improved.




Dodge Neon 2.0 engine

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.


LS7 steel or Teflon® bladed scrapers now available as well as modified GM LS7 and LS9 windage trays.


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



The Nissan SR20 series parts have recently been upgraded and many new variations are available, including steel and Teflon® scrapers for narrow blocks.



Toyota 2GRFE V6




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.



Nissan VQ37VHR

We have received feedback and dyno testing indicated that the combined system below significantly improved the output of the stock engine from 4400 rpm and peaking over 3.5% at 7500 rpm.



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.
