T24: TFS aluminum heads, Edelbrock Victor EFI manifold (PN 29785), F.A.S.T. EFI system with Accufab throttle body and 30 lb-hr injectors at 50 psi COMP Cams Xtreme Energy EFI prototype hydraulic roller camshaft (281/288 advance duration, 230/236 duration at .050, .544/.555 lift with 1.6 rockers, 113 LS) straight up. COMP Cams 1.6:1 Pro Magnum roller rockers, 36 degrees total advance.

T24 was actually supposed to be just a back-up test to confirm the previous month's results just like we did at the start of every month so nothing was changed at all. Only this time the power fell off, and no one knows why. Since we were already on the dyno, we figured we'd continue with our planned day's tests and swap some rocker arms anyways.

T25: Swapped COMP Cams 1.5:1 Pro Magnum roller rockers on exhaust only.

For T25 we pulled an old-fashioned hot rodder's trick that sometimes works today. We left the intake rockers alone and swapped a lower ratio set of exhaust rockers on. That allowed DM to breath just a little more air into its cylinders and helped to make a little more power because of it.
