Has anyone ever put a stock S197 on a dyno? I have an 09 and was just wondering about where the car started. I ma putting mine on the dyno in a few weeks and would like to compare.

 

Anywhere from 260-280 rwhp and about 260-270 tq, thats probably a little on the high side?

 

mid 270's rwhp and 280-290 rwtq for a manual

 

Dyno's of a stock GT are only going to give you a rough idea of how much power you've gained, as every car is different, every dyno is different, and every dyno tech does things a little differently.

 

a better way to see you progress of power is at the drags. take it bone stock down the track, see what it traps. then add your mods and run again. see the difference.

 

Variations in stock power levels are rarely due to the motor itself. There are so many variables it makes literal power declarations almost pointless. Temp. humidity, elevation, which type of dyno, dyno calibration.

Best use for a dyno is merely as a before/after comparative tool, on the same dyno.

 

I didn't dyno my car bone stock but here it is with an axle back and the meziere water pump.
