tuna can vs. deep sump vs. Accu sump Options

[jmargush]

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.

Yes. My 914 road racer was built around 1999, right about when Hoosier started getting sticky tires, and the previous owner kept popping engines due to low oil pressure. He tried tuna cans, bigger sumps and still had failures so he finally gave up because the regs did not allow him a proper fix...which was a dry sump system.

When I got the car it was the first thing I did (while rebuilding the engine). I use this pump:

I use a Canton oil tank up front (it already had a front-mounted oil cooler). But for general autocross and street use I suggest you could use a 914/6 tank in the stock location.

As for Accusumps, here's my thoughts on them:

For any kind of competition on sticky tires, I strongly recommend going dry sump. - GA
