LS1 Stalker Article

In the absense of an official reply from Brunton Auto, I will attempt to answer the question about LS engine oiling.

 

As far as I know, I was the first to install an LS engine in a Seven AND seriously race it. I know I was the first with a Stalker.

 

My LS3 now has a full dry sump system. The history follows:

 

Note that all my racing is done with full race slicks. I do not race with street tires. I doubt it but your results might differ.

 

The initial install was with the stock oiling system. This resulted in no oil pressure on hard turns due to starvation of the oil pickup.

 

A 3 quart Accusump was then installed. This helped, but prolonged turns still resulted in very low oil pressure. The 3 quart Accusump is probably a good answer in an Autocross environment with quick turns but IMO is not the answer in a full road race application.

 

A full dry sump system was installed with a remote oil filter and the engine now enjoys perfect oil pressure at all times. It also gained a few HP because of lower windage in the crankcase.

 

I did not spend the time and money to install the dry sump system so that the car would be cute. I think it is needed and does its job very well. There is a reason all serious race cars have dry sumps.
