The car and engine had about 170k miles on the clock as of that run. The motor was a stock 2.2L DOHC TIII with a larger Garret T3/T4 turbo and Spearco FMIC. I had a few other things done but most were little more than repairs done to a very worn car (clutch, differential, shocks, etc). With better rings (mine caused blow-by so bad that the dipstick would pop out under 20psig) and slicks, that combo has gone 11.68@120 in an otherwise stock Spirit R/T.

Considering the altitude and track conditions (neither of which are accounted for in the timeslip), I don’t think a 13.8 @ 104 out of a bone stock C5 is that far out of the ordinary. That’s about 0.5 seconds off what a professional driver would do under ideal conditions. He might be down a couple of mph on that run, but so was I.

Nice car, the R/T Spirits are sleepers. Also, congratulations on finding t he slowest 97+ Corvette ever.

Nice! Any mods done to that car?
