great job your hard work is appreciated

How hard is it to replace?

'06 Quicksilver Z06

Not hard at all.

Dreamin even did a writeup on the install.

Very interesting results, seems this is a needed modification to 06-08 Z06's if you plan to track the car. So the only change from the stock tank is increased oil capacity in the LPE?

I think the results indicate that this is a needed modification to '06-'08 Z06s if your car is capable of exceeding 1.0G for 4 seconds on left hand turns, as a result of prior suspension and/or tire upgrades.

On racing tires, or with other suspension upgrades, this is possibly, or probably more prone to happen, than on stock runflats and the stock suspension.

Very few compeletely bone stock down to the tires, failures at the track due to oil starvation, have been described on this forum. You can probably count them on one hand.

But if your car has been modified to where it is capable of exceeding 1.0Gs in a left hand turn, for 4 seconds or more, then you will probably need to make this other modification to it, in order to avoid possible oil starvation issues.

So from what he has posted so far, one can derive that: If you have made any modifications to your '06-'08 Z06, which would allow it to exceed it's already phenomenal handling capabilities on a road course, well then you may, and probably do need to make yet another slight modification to the oiling system.

If your car is completely stock, then you should be fine, the mere handful of completely stock track failures due to oil starvation that we have seen in here notwithstanding.

Reviewing the posts on this forum, one finds that there have been more LS7s to pop on the road course due to oil starvation while on tire, brake and suspension upgrades, than there have been on stock , brakes and stock runflats. If an LS7 equipped Z06 popped on a road course, then chances are it had one or all of those modifications done.

The thing is, some people look at tire upgrades as "minor" and sometimes even neglect to list them in other posts or surveys logging the failure. Tire upgrades can make a significant difference.

As mentioned before, it is extremely rare to see a description of a showroom stock Z06 fail on a road course due to oil starvation.

'06 Quicksilver Z06

He is running Pilot Sport Cups and Brembos. It would be interesting to see his results on say, Hoosiers and/or coilovers. But the information he has posted up already is surely well appreciated.

Thanks again Dreamin'

ANOTHER STUPENDOUS GEEK EFFORT !!!!!!!!!!!!!!!!

I had a showroom bone stock car that lost its engine after 3 hpdes and 3300 miles.
Hopefully my story IS a rarity.

'06 Quicksilver Z06

It is.

Other than yourself, elh0102, and one other guy whose name I cannot call right now, those are the only confirmed stock on stock tires on track failures, due to oil starvation which appear on the forum.

Hi Dreamin, can you post the same graphs for California speedway when you had the stock tank? I want to see where problems can occur and how bad the Nascar turns 1 and 2 are. I will most likely be there in a few weeks.

Thanks Leo

He is going to test it on the next 2009 Corvette Challenge event, which is at ACS !!!!

I know of 1 that happen recently at the NCM HPDE at VIR in July. He blew at 85 mph on the back s's and the GM rep warrenteed his car on the spot. Bone stock engine.

Dreamin again you are responsible for the two of the most important posts on this forum, thanks! u should get some royalties from LPE.

My question is looking at the data the pressure on the stock system never goes below 20 and on the LPE system never below 25. Is this 5 psi difference saving our engines? How low is too low on the LS7? Does anyone know?
Also this is on stock suspension right?

i am sure i helped you spend some $$ after track attack

I think that the problem is air geting into the oil going from the tank to the engine, thus droping the pressure. Although, I don't believe the pressure drop is what is causing the problem, rather, the air geting injected in the bearings (which is causing that pressure drop)...I could be totally wrong on this too...

I just completed my LPE tank install today. I think I ordered the last "off the shelf" one they had in stock a couple weeks ago. My core will be shipping back this week. I had them add a Stef's oil pan heater element to the tank so I can get the oil up to temp faster. I always hated driving the Z for several miles before the oil would even get up to 130-140f... I also put in the Aviad tank insert. Nice piece, but had to open up an extra hole in it to clear the heater element. These parts make a lot of sense when you see the whole system. I wouldn't mind having the Katech scavenge pump, but I'll have to wait until I do some serious engine work.

Overall the tank swap isn't a bad install. The toughest part is probably wiggling the tanks in & out since the mounting flange for the upper & lower half get pretty tight by a wire harness & require a little finesse. I did it myself without too much extra trouble though. Dreamin's write up is accurate so give it a read if you're going to do it.

I was pleased to see that I had only a very tiny amount of metal on the drain plugs. Very minute, small particles. Nothing to worry about at all. So as long as my oil analysis comes back looking good, I'll feel safe about not having any damage to the bearings, even after my track outings.

If you compare Thill with the stock oil tank (turn 2) Dreamin is 85+ mph and his oil pressure is ~21psi. 21psi @ 5k rpms is bad!
After the LPE tank installed, Dreamin went to Thill same turn and now the oil pressure is stable.

Now if you are in a slow turn and your oil pressure is 20psi but your rpms are at 2500, then 20psi is fine. Dreamin made it possible for all of us to see.
The rule of thumb on oil pressure is ~10psi per 1k rpm

The data doesn't lie, the LPE tank works.

Hope that helps

What does the Aviad insert cost a person? I looked on their site, and it just confused me.
