Hump Day Holeshot: 8-Second Heffner Performance Twin Turbo Viper

We all know Vipers are fast cars. C’mon, it’s got a 8.4-liter V10 in it. But how about a twin-turbo version of a 2002 Viper? Yeah, we can imagine it being a real powerhouse. Well, Heffner Performance was out to prove that the stock Viper with only a few modifications (although pretty impressive as they may be) can propel a stock Viper down the quarter deep into the single-digits. With no roll cage, no spool, no parachute, a stock T-56 transmission, a 3-inch Corsa cat-back exhaust kit, and with its full weight, this twin-turbo V10 explodes down the track at an impressive 8.75-seconds at 163.4mph! Check it out for yourself:

Of course, 8-second passes in an independent-rear Viper is impressive, but how about Heffner Performance’s record-breaking 7.99 seconds 1/4-mile pass? Producing over 1900 horsepower from the dual-boosted V10, this wickedly fast Viper snaps through gear shifts so violently that you’d think each gear change would shatter driver Gary Javo’s spine!
