lol ve-t+aem= 36mpg highway. would be even better if I had a 6speed swap. My car is also not as heavy as the p11. You could always cut the room off for reduced weight and better mpg.
The RR has been running pretty good, though I do feel like my TCT is still complaining on cold starts (even though I replaced it in March). The motor made 235whp on mustang dyno at 10-11psi on a GT28r two weekends ago.
