Mark Stielows latest Thomson Automotive 427 just came off the dyno, and the numbers are in. 957 HP and 970 ft. lbs., with 850+ ft. lbs. from 2000-5700 rpm. Going in his latest 69 Camaro “Hellfire”, I’m thinking this one should be the best and fastest yet!
Here’s a quote from Mark Stielow:
“A tick more boost via a blueprinted blower and a slightly smaller pulley. Also a very good inlet tube and reworked blower inlet. On the exhaust side we corked it up to simulate full exhaust via flow restrictors. So I think we will clear 950 HP installed without much trouble. We also use 35 C intercooler water to be more real world. With chilled water we can clear a 1000 HP no problem? Mayhem was fast this should be even faster with more power, less weight,and more down force.”
