Today I ended up putting the SS on the dyno during the vegaslsx synod day at sin city performance. Two of the three runs imho are not really worth mentioning because the something was not right. No way I made 700 and 400+ ft-lbs of torque. From my understanding, there was a grounding issue on the first two runs. Anyways, the cleanest run that i had was 308rwhp and 324 rwtq.
My car has the following mode from Slp
- hurst shifter
- power steering cooler
The mods that i have added are,
- free RAM air mod
- Slp aftermarket lid.
What does everyone think about the numbers vs. Mods?
It seems reasonable .... bone stock M6 SS's were dyno'ing in the 270rwhp/280rwt range according to the road tests back in the day. There were several making a bit less and a handful making more. There are several variables to consider ... mileage, maintenance, weather conditions, fuel, etc.
