Here is some in car footage of a 93 mazda rx7 with a 20b three rotor turbo at mission raceway , bc, canada.

This race had 24 entrants from a 12 hr sebring winner to national scca champions, instructors, and indy sedan champs. Entrees include gt3rs, m3 v8, gt1 racecars, trans am corvette and Beretta, super7, etc.

Its a 30 minute sprint race with a $10,000 prize fund, all for the childrens charity.

Our rx7 had some mechanical trouble , hence the long turbo lag, but it made for some great racing.

enjoy
