I'll take a stab at this.....

1. Domestic Import Challenge = D.I.C

2. TRID Shootout = Tampa Racing Import Domestic Shootout

3. Cubic Inch Challenge = C.I.C

4. EGG = Economy vs Gas Guzzler

5. DMV Invitational = Dale Mabry Vehicle Invitational

6. DMI = Dale Mabry Invitational

7. Tampa Racing Bench Race Day = TRBR Day! Gimmie a break. I'm
runnning out of ideas.

8. SYFMAR Day = Shut Your Fucking Mouth And Race Day!!!!!!!!!!!!!!
