SRT-10 stage 1 performance results

[Daniel Cragin/DC Performance Inc]

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.
