Okay, my car is basically stock except for the 2 minor mods ( in sig) I have had it for about 2 months now and it seems to me that im losing power? I cant be sure of this maybe its just me being used to the speed? What my question is, is there any little tricks i could do to see if my car is at the right amount of rwhp it should be? Im talking about something else than running and dynoing the car? IS there a little trick of some sort so you guys know your car is running right. Im about to run for money and i think im just paranoid. Thanks to all and i know it sounds like a stupid question but if there is a way i would feel alot better.

 

Find someone with an identical car and drive his, or race him...

Really...Dynoing would be my only guess to check power.

 

I would guess you're just getting used to it. Time for more mods.

 

Or take it to the track.
What I do is take the car to the track at least once a year (actually do it as often as I can) and compare my times, that way I know if it is running the same or not.

 

With street tires and good tread i should run about low to mid 13's correct? OR more importantly whats a healthy trap speed? 103 to 107?

 

Probably 107-108
