Now that I have an oil pressure gauge in car I can see drastic swings in oil pressure while on the autox course.

So this prompts a few questions.

Does the Type IV have an oil system that really isn't adequate for higher G loads and quick direction changes?


Will I see an noticeable difference if i go tuna can sump vs. Deep sump vs. Accu sump?

I understand the Accu sump is likely the way to go but there is also a significant entry cost difference and more involvement on the install.

I hate to spend the money on the easy install of a tuna can if it isn't going to make a noticeable difference and I should have just put the money toward the Accu sump.

I had a deep sump installed and it took forever for the oil to get to operating temperature and it hung about 1 1/2" below the engine bar, ground clearance??. I installed a tuna can and have not seen any loss in oil pressure when hard corning. No experience with accusump.
