Pushing past 9k rpms! Wet sump solution...

bullitt5897 · 04-30-2015, 10:44 PM

So as many of you know the oil pumps on our cars begin to go at just over 7500 rpms. The option most of us say to go is dry sump which is costly, complex and will cost you your air conditioning. Well as I was working on my build I had several conversations with GTM on the issue. They came up with a wet sump system that is rated to 10k rpms... However, I would say it is best suited for the 9-9.5k rpm range! This is the solution I will be going with in my builds here in the near future as soon as it is in stock.

By extending our power range an additional 2k rpms this will allow me the opportunity to get better runs and use out of our stock gearing. For those who track their cars, this will help eliminate oil starvation and ensure reliability.

What ever your stance on GTM's business decisions please keep it to yourself.

Holy moly, what is the difference between wet and dry sump? I've been dreaming about something like this. Where is the mounting location? Last but not least, how much for this bad boy.

Some of the main benefits with a dry sump is constant oil supply, more power can be generated (by creating extra crankcase vacuum) and since there is no "oil pan", the engine can be lowered thus improving handling and a lower center of gravity. Oil capacity is no longer an issue, oil is no longer splashing against the crankshaft (which can lead to hp loss). While cornering, accelerating, braking and so on there is always the same amount of oil supplied (so no more oil starvation).
A wet system is what most cars come with and the cons to it are the opposite of what I mentioned above.
The bad about a dry system is how complex it could be and the extra weight due to additional pumps

Nice. Ok, I see how the oil gets out of the pan to the pump. Now where does the oil go back into the engine?

MR.nismo · 04-30-2015, 11:33 PM

There is a tank that can be mounted anywhere in the vehicle. There are at least two pumps. One pulls the oil from the engine while the other pushes the oil back in. (in a nut shell)

bullitt5897 · 04-30-2015, 11:35 PM

There are more parts to the kit... I am curious to see the rest of the kit. As for a dry sump I would love to run one but don't need an extra complexity or weight and if a wet sump system can handle the extra rpm's I will take it all day.

Elmo370z · 04-30-2015, 11:36 PM

So.... What your saying is that even with this wet sump supporting 10k rpms there is still a strong possibility that
It will fail, and with a dry sump you wouldn't have to worry about it?

MR.nismo · 04-30-2015, 11:37 PM

Bullitt, what are the dimensions of this oil pan? and how much oil is designed to hold?

Lol, c'mon now...

Elmo370z · 04-30-2015, 11:59 PM

Could our stock block handle anything past 8k reliably or is the jury still out in that?

MR.nismo · 05-01-2015, 12:07 AM

Stock, no my friend.

That's a dry sump. Wet sump. Usually one pump. The oil pan is the tank. There is no external tank. That's why you see the oil pan for the GTM kit being so deep. Usually routing of the oil flow for a wet sump. From the pan to the pump, to the oil filter, to the cooler, and back into the engine oil gallery.

Dry sump. From the pan to the 1st stage of the pump, to the tank, to the 2nd stage of the pump. to the filter, to the cooler, back to the engine oil gallery.
