Big Tuna Motorsports went [email protected] with a 1.87 60' today at MIR. Making around 150whp. Slicks are too tall so once the shorter slicks are on it should go 12.5's.
D16Y8 transmission built by Whoopee Doo Racing.
MFactory 1.565 3rd gear, OEM 1.172 3rd gear used as 4th gear. 5th gear delete. OEM welded diff as the OBX that was going to be used had .010" runout straight out of the box it was shipped in. Carbon coated synchros, 2-3-4 scuffed gear cones, CSB race staked. Shifts smooth as butter at 8,600 RPM. 2step launch at 9k.
