i know this has been answered before but i have a 5.4 and i was wondering if removing my windage tray would help with horsepower even if it is only a small amount? my truck is mostly drove on the street with the ransom trip to the dune and what not. any help would be great. also are there any other small things other than e-fans to do?

my mods: injen cold air, bbk 80mm throttle body ported to 90mm, throttle body spacer (i know not worth a dam* but i got it for free) gibson long tube headers, custom 3 inch y pipe no cats, magnaflow cat-back, a sct tuner custom dyno tuned, and i also have a 75 shot of nitrous(hardly ever use it). like i said any help would be sweet.

 

Wouldn't there be a lot of oil splatter?

 

oil cavitation = bad ju ju


i wouldn't recommend it. the windage tray is what lets oil drain in smoothly (a la, no sloshing/spattering), and prevents the oil from pushing to one side of the block or another (think centrifugal force on a long sweeping offramp).

 

Thats not technically correct....

Windage tray has nothing to do with holding oil under the oil pump under high g loads, that is a baffles job. Windage tray just reduces oil splatter and stops the crank from splashing in the oil and casuing cavitation.

Sorry! I'ver built many racing engines so a nerd when it comes to that stuff

 

i figured they were of similiar design to smaller engines (i've got 4 subaru motors and a handful of of honda/acura motors under my belt, both my own and friends)...only built v8 i ever wrenched on was a 400CI aluminum block beast that ran on alcohol lol.). for instance, on an ej207 (the motor i built for my 05 WRX), the windage tray also served as a baffle.

and i never mentioned holding the oil under the pump level. i meant more like helping keep oil settled in the pan. i know oil pressure was always an issue for me (the WRX, being a horizontally opposed 4cyl, tended to pool oil in the heads under long highspeed sweepers @ NHIS)



*edit, either way, we agree it's not a good idea...especially for (at best) minimal gains you might see.

 

Ding ding ding... I was right...

 

so i was just wondering A. will i notice a power increase? and B. will this be bad for a motor? simple question. lol

 

A. You'd be more out to see a decrease in power due to the sloshing oil coming in contanct with the swinging crankshaft more thus causing more parasitic drag. B. No
