Two things scare me about this, the words "shop assembled" and "bolt on kit".

What kind of development testing would take place? Any long term durability testing before bringing the parts to market? What kind of quality checks would take place?

I mean, were not talking about a piece of exhaust pipe or an intake here, were talking about the blood of the engine. I think everyone would need some kind of assurance that every kit would not only perform better than the stock oiling system, but would have OEM reliability, fit, and finish such as systems found on the z06, porsche, etc.

No point in turning a fair oiling system into something that looks better on the internet, but performs worse.

I have purchased WAY too many aftermarket parts over the years that seem decent as an inital prototype, but have a long way to go in terms of development and interfacing with other systems. And its not a big deal if were talking about shift knobs and air-filters, but when your messing around with the oiling system, it better be nothing short of perfect.

 

I stand corrected.

 

Just to chime in quickly.

Dry sumps, if you read about them, seem to be great. There are dry sump kits out there for the 6 bolt 4g63, as a matter of fact I just sold the brand new I had complete, on Ebay for $700.

When we converted to RWD it seemed like it was going to be a needed part. Brent Rau actually developed one a few years back and ran it. He just ran a 6.86 at 199 mph, WITHOUT a dry sump and after using it for a very short time went back to a normal oiling system. We never did convert over, we just built a better oil pan for our RWD's.

I see no benefit in it and just want to say this stuff so someone doesn't waste a bunch of time and effort building a kit.

 

David, would there be any benefit to a dry-sump for road racing? Does the 4G63 suffer from oil starvation under sustained lateral loads?

 

From the looks of the Time Attack car and bottom end the oiling system seems fine.
