Dry Sump?

I've seen these words come up a few times and after checking out reddtarga's car I started to ponder if the stock oil system was adequate for track driving on semi's aka more than 1g's. I'm probably overreacting here but I think with good suspension and decent brakes with semis on an MR2 it's capable of achieving over 1g even just a little. I've heard it's costly tho and to be honest I think it's overkill for a mostly street driven car (with high limits) but the risks are still there lol
I also read a certain article were they said there was barely sufficient oil in the sump :S
Maybe there is a less hardcore and cheaper version short of going dry sump? Does your electric pump work while driving too red?
Thoughts?

If your super worried, you could always look at an accumulator, they are much cheaper then a dry sump.

Basically it's a pressurized oil canister with another 1-2L of oil. If your engine oil pressure starts to drop, it starts feeding back into the motor. This will help out on those tight, high G corners where the oil pump might suck a bit of air for a second or two.

id also recommending that you run a slightly bigger sump when you use an accsump, particularily when 2lt or bigger. if fitted with the pressure sensor and electric valve, they only refill the accumulator when you have sufficient oil pressure. if you have a time when you go through a long corner (ie. the first boob at winton, they can pump 2 litres into the engine, and until the accusump fills back up, you have that extra oil in the pan, which can cause its own problems. so consider an accusump in conjunction with or after you have a bigger baffled sump.

no worries. And another thing is when you run the electric solenoid models, when you key on, they dump the oil in, so you start with instant oil pressure, which will help engine life in the long run.

Shmaozaow thanks for the replies everyone! I guess I wasn't overreacting then but wonder why it took me this long to find out about this stuff considering how oil is the life blood. I'm gonna have a look at all your suggestions and go for cheapest + easiest (as opposed to hardest and more expensive) without cutting corners but so far accusump + modded sump/baffle is optimal. Also having that electric solenoid is a great idea MCT since engine wears most during start up which was the real reason you put that electric oil pump on if I remember.

Oil surge management sounds reassuring :)
Yeh I don't think Iain or Adrian run extra sump setup and they do low 1:13s. Even with said handling mods I don't think the car is even capable of said times lol but I still think it's cheap insurance for those with extra pocket money hehe. I'm thinking sometime in the near future (MTC :P) but only once I get my Koni's
At least it's a functional mod instead of a body kit hahahah jksssss (to each their own)

Nek minute engine blows LOL jks
The problem with oil press gauge is that by the time you see the needle drop it's already too late. But still useful for choose optimal oil weight.
Also if we overfill the oil wouldn't that put stress on the crank thus robbing power and cause some frothing?

Also isn't that what an oil catch can is for?
