We just finished testing our stage 1 SRT 10 package. Peak hp went from 433rw
to 476rw and torque went from 464 to 502 with the following changes. Stage 1 street port heads (full exhaust port, intake pocket port, stock hardware except for Comp Coupe valve springs),1.7 ratio rockers, K&N filters and rear crossover delete with Borla mufflers. Considering that this is only a minor port job with no headers the performance gains are very respectable. This particular package requires no tuning and the upgrades will pass a visual and tailpipe smog inspection. Information on our stage 2-4 packages will follow, stay tuned. |

Great results for no obvious visual changes - look forward to hearing results for cam, headers, and street fully ported heads.

Dan,
Did you happen to get a dyno sheet comparison with just the 1.7 rockers installed, before the other upgrades? Interested to see how they alter the torque and HP curves. |

Doesnt the SRT already come with 1.7 ratio rockers? I remember reading that somewhere.
