recommendations for a hi output application

[s4audinut]

We have just added a dry sump system to a 1.8t audi turbo engine running 30lbs boost and doing about 6.5 hp per ci at the crank. Car has billet mains, girdle w.mains tied in and a solid dry sump pan. Have a peterson 3 gallon tank with in tank heater.

Car has 2 programs, one that is exclusively track and uses 103 oct w/Xylene runs at 550AWHP, and other is a street tune (car is on street as well) and uses 93 oct and runs at 420awhp. I would like an oil that will hold up to these varied demands. Car will always be run till hot, no stop and go. Have an oil cooler. Any BTDT as far as having dual purposes with oil. Car will never be run below freezing due to traction issues, so low temp. tolerance not a factor.

Please tell me about your experiences with this.

Thanks and new to oil

Redline 5w-40 might be good. It is shear stable and will be able to stand up to abuse.

Redline or Cosworth oil.

Many race engines I have seen young Skywalker... Use Redline, its the best for high temp and racing applications.
