After some tuning, our coupe spun the DynoJet rollers, pumping out 353 rwhp and 346 lb-ft of torque. Our best before was 276 rwhp and 279 lb-ft of torque.
Once in the staging lanes in Gainesville, we let the SSP cool down before making the first run. After heating up the Nitto NT05R's, I staged and foot-braked revs up to 3,000. When the green light lit, I traded feet, spinning the tires off the line to a 1.96 60-foot. After pedaling it to hook, the first run yielded a 12.24 at 114 mph. I decided to lower the launch rpm to 2,500 for the second run, which resulted in a little tire spin, but didn't require me to lift. The 1.83 60-foot produced a 12.02 at 114 mph.
With 11-second e.t.'s in sight, I lowered the revs on the line to 2,000, and when the tree dropped, I traded feet. The coupe transferred its weight onto the 275mm drag radials and dead hooked to a 1.78 60-foot. Though we've seen 1.69 60s from the coupe, that was only when it was dressed down and wearing skinnies. After going through the traps, I wheeled over to the timing booth to grab my time slip, which read 11.92 at 114 mph. I backed it up with an 11.94, also at 114.

12 Once complete, we dropped the new 347 in place.
Though we're not legal to run quicker than 11.50, we opened the nitrous bottle and headed back to the staging lanes. Since we had an issue with tire spin naturally aspirated, the juice certainly wasn't going to help matters. Still, we gave it a shot. A soft 2,000-rpm launch permitted a (spinning) 1.90 60-foot. After lifting and reapplying the throttle two times, both resulting in tire spin, we aborted the run.
In the end, we're still happy. We built a complete do-it-yourself 347 for under $7,000 in our own shop that is daily driven and runs 11s without even a tire change. That being the case, we'll probably just leave the juice at home.

14b Though we didn’t get a clean nitrous run, we expect low 11s. If we’re lucky, we might squeeze off a 10.
