Sounds like you're having fun with the project.

The logical next step, especially considering impending highway use, is to improve the aerodynamics.


- partial grille block (assuming you have an accurate way to monitor coolant temp)
- remove/relocate the passenger mirror to just inside the glass on the A-pillar
- test an air dam (sometimes they help, sometimes they hurt)
- and/or smooth undertray
- smooth wheel covers
- tire spats/deflectors
- etc.

Do you have any options for re-gearing the car? A taller final drive or top gear would probably help as well.
