Thoughts on my s600 dyno results
so yesterday i went to dyno my car b4 i sell it to see how much i am putting to the ground
my car is an s600 2003 with 115000 km on it
mods are
1- gutted cat + resonater delete
2- k&n drop in air filter
3- bosch 010 upgraded ic pump
first thing i did was cooling the engine for 15 - 20 min
via a big fan
then put it on dyno mode
run was made on a mainline dynamometer it has 2 readings
dyno jet + mainline
on dyno jet readings i got ( 491 rwhp ) yes 491 is this normal ?
on mainline readings i got ( 416 rwhp )
my car is running a bit rich AFR 10.02
what do you think
i apologize for posting in the amg section but seems more appropriate place than the regular w220 section

If you've ever had the car to the drag strip the trap speed is a good indicator of power. With speed, weight and density altitude you can get some pretty useful data.
Times are pretty useless for figuring out power.
Fuel type is a factor too.
