How much Power should I lose??

[JRW Viper]

I have just finished installing the 3.54 gear ratio instead of the stock. I know I should be losing some power on the dyno but can anyone give me an estimate??

Stock 3.07 RWHP = 550
New 3.54 RWHP = ???

The car is on the dyno as I am posting this message. I just want to have a rough idea

Thanks

Isn't the correct answer "none?"

There is a small loss due to gearing efficiency but it is small. Maybe 1/2% or 2-3 hp.
