Sustained track use
 

Hi guys, I have a Scimitar with CA18ET with roughly 170bhp. I'm prepping it for racing this season and have a few questions for those who track their S12.
I'll be running on semi-slick trackday tyres like AO48s and want to know whether the increased lateral G will effect oil pickup in the engine. Should I be looking at getting a winged sump made?
Also, should I fit an oil cooler?
Races will be up to 30 minutes long.
Cheers, Raz :)

Hi Raz, sure you wanted someone other than me to answer ;)
my two penneth... ive never had troubles so far on sticky List 1bs, but thats for short runs. as for the oil cooler, i would have thought so if you are using the std water rad, as the nissan water/oil exchanger may struggle to keep the temps under control. a larger fan on the rad and poss a larger rad will help, but if not a 16 row oil cooler too. you can always blank off a bit of the oil coller matrix with duct tape if it overcools. a remote oil filter with oversize filter will give an extra bit of oil capacity too
Stew B has had Et and DET sumps sides by side and reckons the ET is better design in trems of the splash plate.
ideal situation would be an Accusump for surge protection, but currently i dont think its necessary on my car. i intend on hooking my oil pressure sensor up to my data logger to see if theres any momentary fluctuations. will let you know when i finnaly get out for this season:rolleyes:

Definately fit an oil cooler on a ca engine for sustained full load. Having surge plates in the sump is nice for piece of mind at least but I do not know if it would be nessessary. A good set of gauges and an extra oil pressure warning light is also a must:)

I think you know how much I value your experience Craig ;) Just thought I'd see what the S12 fraternity have to say.
Thanks for your comments both of you. I have an oil cooler kit in the garage for an S13, that should bolt straight on shouldn't it?
Raz :)

yes it will fit straight on no probs:D
