2022 Big Bore Thunder

Saturday – Sunday, June 4-5, 2022
Pueblo Motorsports Park, Pueblo, CO

Our Big Bore Premier Event of the Year!


You are invited to join RMVR and the Thunderous Upper Class for the Big Bore Thunder event at Pueblo’s venerable road course over the weekend of June 4-5. V8 entries have dwindled in recent times, and without the big bore cars we may have to rename this event ‘Small-Bore Buzzers’. Don’t let that happen! We encourage anyone and everyone with a thunderous V8 vintage racer to bring it out, and we’ll even help cover a few laps of gas! [See below for details]

Some Details:

  • PMP will host a Friday Test & Tune for cars only. Sign up through PMP or the MSR website. No pesky motorcycles this year!
  • RMVR Tech and Registration at PMP will be available from 3:00 pm to 6:00 pm on Friday, and 7:00 am to 8:00 am Saturday.
  • Paddock Access. RMVR entrants will have access to the paddock all day Friday. Arrive early for a good spot; only reserved plug-in overnight locations will be blocked off for RVs.
  • The Drags.  Friday night drag racing, a staple of PMP, will return after the road course goes cold, and is scheduled to end at midnight. Be prepared!
  • Saturday Happy Hour.  Volunteers, racers, and family members are all invited to a Happy Hour after the track goes cold Saturday afternoon. This is a great chance to meet, greet, and BS over complementary beer & wine, with some light appetizers to fend off starvation. Come to the pavilion to let down a bit before you head to the big city of Pueblo or your RV for dinner.
  • Yes, a “Gas Bonus!”  We won’t have much Big Bore Thunder without some big bore racers, so if you entering a V8-Powered vintage racer for the weekend, you can request a $30 credit when entering.   If you wish to take us up on that offer, simply check that box when entering. (No V8?  Don’t check the box. . .people are watching.)
  • C’mon Down to Pueblo.  RMVR welcomes current racers from CVAR, SWMS, HVR,  and other VMC clubs with vintage and historic race cars from your organizaitons.

The Feature Race of the weekend will be the Thunderous Upper Class, consisting of A and B-Production Sports cars and A-Sedans, with a mix of Porsche, BMW, and perhaps an Alfa or two for good measure. Bring on the big-block Corvettes, GT-350s, Tigers, and E-types, and the quick “Saloons” including A-Sedan Camaros, Mustangs, Javelins, Cudas, and Firebirds.
