I'm building up a 2013 SHO for road racing. A common modification is to add a windage tray or performance oil pan. Has anybody found a source for either for the 3.5 EB? Thanks.
I researched. Came up empty.

Yeah, I looked as well after seeing benefits above 5500rpm on other engines (LS's). You'd have to have one custom built. *but* if you are stock heads, valves and your rev limiter is OEM It may not yield good return value.

Why is that(stock valves...) I think the sho makes a great track car you leave it in sport mode and you stay high reving all the time you start to see just how good the car is except for your ptu fluid will probably need changed but you should be changing the engine oil too.
The baffled oil pan is one thing that was over looked. And poor planning of changing the ptu fluid.

You better get the extra no questions asked insurance on that spicy rental!!!!

Bigger exhaust valves will help with the breathing and reduce pumping resistance, that would help rpm a bit/'build faster' and help build boost sooner as well as a increase in TQ on the high end, Better intake valves are hit or miss on some platforms with regard to fluid dynamics so im on the fence for SHO's with the current config of the heads. But the flow of the OEM heads is
absolutely restrictive. It it not just a limit of the parts for the lower RPM limit, there are flow issues with the layout.
I am
***extremely*** interested in BPD's build and see where the RPM limit is after final tuning and the TQ power curve. With oem parts our power falls off the face of the earth right after 6200 rpm.
If we can get a build that will push 'good' power over 6700+ rpm plus well see a rash of new track records as the 60' drops .. added: A windage tray with a scraper for that kind of build would yield and easy 15ftlbs at mid and 20+ @ higher rpms..
My only concern is windage scrapers need replacing, in our config that's pulling the block :(

Gearhead is working on cams that will get us another 1K of rpms just for this reason....
Hoping it works out !

For auto crossing a car you don't need any of that it's more up to how good of a driver are you.
break late, soon on the gas, plan your line.
But preventing the engine starving it's self from oil is very high on the list of needing.

Hey Everybody.
Thanks so much for all of the comments and ideas. After reading two stories on the internet about drivers that attributed blown engines to oil starving during spirited driving on twisty roads, which sounds a lot like racing at Oregon Raceway Park, I started to think about a windage tray and scrapers. Most SHO enthusiasts are probably after the same thing... additional horsepower and reliability should not be mutually exclusive.
My neighbour knows of a fella that custom builds windage trays for his own racing cars, so I may have news in the future. A custom built windage tray won't be cheap, I'm sure.

I'll be interested in one.
Shoot me a PM on a range of expected pricing.
If a deposit may be required, I'm ok with that as well.
