Some progress over the weekend, didnt really want to wait for the lead time on running a prototype for the block adapter, I went ahead and hand machined one on our manual mill. All we need to do now is make the lines and schedule a day for the track!

Nice work! Love the ability to just go out and machine a part by hand.
Look forward to test results.

Does the LT4 not require an o-ring at the block for the passages?

CGZO6

Yes, gasket with O rings not shown in pic.

0D3PE

Correct, we might o-ring our production product but for now we are going to test with the OEM gasket/o-ring.

MIGHTYM0USE

impressive, im jealous you got ahold of that c7 cad! who do i need to send my first born to for that?!

0D3PE

Haha, it actually costs a min of 2 children...




* Looks like we are scheduled for a final test fit next Monday and we have the track rented next Wednesday for testing! We will log a session with all the OEM components then change the parts at the track, then log another session.

Crap now I have no reason not to buy a new Z06. Way to go! I have been sitting on the fence because I didn't see any great cooling options, but this is clean. GM needs to give you a kick back for selling cars.

Got our prototype unit powercoated and installed on our test vehicle for tomorrow!

Well we went to the track today for testing, we made it onto one session but at the end apparently the BCM gave out and was turning stuff off in the fuse box including the ecu resulting in flickering gauges, exhaust valves opening and closing, and not being able to connect to the ecu.

On a side note, from the log we got, we had ect all the way up to 243 degrees and oil temp got up to 280 degrees. We are anxious to get back to the track, if the dealer can get this issue fixed we can be out again next Thursday and see how our products work!

Subd from a few hours away. I had 280* oil temps at msr in 60* weather on a NA c7.

Im very interested. Im holding back on buying a C7 Z06 until i find a proper oil cooling kit.

0D3PE

Sorry for the delay everyone, we got the Z06 all fixed up (had a bad harness causing shorts to ecu), then we had a track rental scheduled but we had to reschedule due to heavy rain and flooding here in Houston. At the moment we are scheduled to test at Texas World Speedway May 14th. We will keep you posted once we gather our data!

Something to keep in mind during your testing...

I had breathless race oil coolers on my C6 Z06 along with Katech lip and under tray carbon floor board, the setup worked great on track, but when I took the car to 186mph the under tray floor board exploded due to the high air pressure coming in from the location of the fog lights (breathless kit uses fog light opening to channel air to the two coolers on both side).

Also I suggest you put a small pulling fan behind the cooler for tracks that has lots of 2nd 3rd gear acceleration which doesn't provide enough air to coolers.

How much oil capacity is added with the addition of the cooler?

Make sure you test the kit for top speed runs as the event I had was one of the scariest I have experienced at 186mph.

Good luck with testing

Hmm, so I also had a bunch of shorts. I wonder if it's the same harness. Do you get 10 to 14 codes? Is it fuse #36? Is the O2 sensor on that harness?

If so I know how to fix it.

0D3PE

So our system will direct air the same as the factory brake duct as ours goes the same route and length. I would agree that if we were simply throwing air into that area it would be an issue.

0D3PE

Our whole fuse box was randomly shutting down, I noticed it after we took our first baseline session, it came back with a rear end service code, then when it was idling the exhaust flaps were opening and closing while the complete gauge cluster was doing the same. Pretty much ruined a $600 track rental for us

LSs1Power

How much extra oil capacity with your system? Also would you consider a twin coolers on both sides? How about the fan behind the cooler?

RapidC84B

Very nice setup. To those questioning "reinventing the wheel" This is the same as all the C5 and C6 oil cooler kids for years. All of the oil flow goes through those ports. In the C5/6 it was the temp sensor housing. In the C7 it's the OEM liquid-cooled cooler brick.

The C7 has a variable dual pressure pump. I'd imagine it will take care of any startup flow w/o issue by acting as a high volume pump when needed.

I'd fabricate a inlet cover vs. plumbing a t-stat in there; KISS.

My only concern is that it would give GM cause to void warranty on a oil-related failure. LT engines have random crank/rod issues. GM could have an easy out saying you modified the oiling circuit even if it wasn't the actual cause.

Looks like we are still on for testing this coming saturday! Hopefully we will have some good data to share the following monday!
