While I have never driven your home track, I vote #4 actually. A car with high mid-corner speed is usually faster on most tracks and although your home track is a "ROVAL" at 1.6 miles, its got to be a fairly small one. Lighter is always better. Having to have 200 more lbs. on board will offset the extra 50whp on the straights and lower your mid-corner speed. In addition, NA horsepower is always more useable power than FI power. The SC will also generate a lot of heat and add probably 60-100 lbs. to the front end of your car which is no bueno, plus you have the possibility of more components to break. And probably the best part, is sticking with NA will save you a bunch of money.
I would also say that at 2975 lbs., you wont need such big tires. I would probably run 275/285 tires max, especially if they are R-Compounds. Thats the size I run on my car with street tires at ~3400 lbs. w/driver and they do fine.
My goal would be to get the car as light weight as possible and add ballast in ideal places if you need to add weight at the end of the day. Then you can remove the ballasts for RTA events. I feel pretty confident your car would be very competitive in Mod RWD at Buttonwillow, Spring Mountain, and some other twisty tracks. Look at Street RWD results from last year. Manly Kao's 165whp Lotus dominated at Buttonwillow and Spring Mountain, did pretty good at AAA Speedway, and did ok at Willow Springs, but also took away the championship.
