Any way you slice it, a single digit ET is very, very quick. It’s always an impressive feat to dip below the 10 second mark, regardless of how much time, money, and effort has been thrown at a car. That having been said, the truly surprising thing about the LS swapped 1984 RX7 featured in this video is just how simple its set up really is, and yet it even breaks into the 8s.
According to the video caption, the Mazda is running a completely stock LS2 bottom end, with a healthy cam, and a set of ported 243 (LS6/LS2) cylinder heads. It’s topped off by a FAST 102 intake manifold, and a 90mm throttle body, and breathes in a big shot of laughing gas from a Nitrous Outlet direct port kit. The power gets transferred to a trusty TH400 trans and a narrowed 8.8 rear end with Moser axles and a spool. Of course, traction is everything and the RX7 is utilizing some 29×10.5 slicks.
As you can see from the video, the little RX7 turns in an 8.99 at 147 MPH time slip at Grand Bend Motorplex, in Ontario, Canada, hanging the driver’s side front tire to the 60-foot mark, and tossing out the laundry at the big end.
