eeek maybe n/a, do that in an m90 car and the motor will

however, i can say from experience my car loved 23-24* of timing midrange and 21* at the top. It pulled like a bat out hell for just being a non-i/c'd rocker car. I never had a good run at the track, but i pulled 106mph traps on a 90 degree day. I'm hoping to have some better luck this year at the track. Maybe get stuff ready the day before instead of in the staging lanes would be a good idea...
