Anyone on here have one?

Nope, one of the late eighties twin turbo hammers was in the auto-trader here fairly cheap not long ago.

Do a search for Callaway owners group or something like that. Also Corvette Forum you might be able to find out what you need.

FYI. There was only one "hammer" Callaway built and that car aka Sledgehammer has been in Germany for over a decade.

My boss had 1 back in the 80's It was nice but compared to a new Z06 it wasn't anything.

what year are you lookin at ?

Lingenfelter drove the Sledgehammer Vette for the Top speed record of 254.76 Mph. I guess Callaway was a sissy and couldn't handle his own vehicles

Yep!

Did'nt call it the Sledgehammer itself, but many call the twin turbo option sold by GM hammer's. GM offered them until the ZR1 came out, so several did get built and the Sledgehammer was built to promote them.

Good friend of mine has an 06 Callaway.

How does he like it?
