These are stage 1 cams...they arent going to show stage 2 numbers guys. I would expect like 280rwhp max. I would take it to a dyno shop and have it dynoed and have the a/f ratio checked. If you arent tuned, you need to go back and get your money back and take it elsewhere to get tuned.

 

StageI cams and no long tube headers, I would think 265-270rwhp could be about right. As mentioned, you can't really compare your numbers to anyone else's number because dynos just aren't that consistent. Take the car to the track and see what it traps. That is a BETTER way to check your power than trying to use dyno figures.

 

ouch. when i dynoed my car with just bolt ons and a sct programmer i laid down 268/292

 

Dyno numbers are NOT a good comparison! Every dyno is different. Same dyno and different day will produce different results. Don't sweat the dyno numbers. Track numbers are a far better representation than dyno numbers.

I've had dyno pulls from 301rwhp down to 280rwhp just recently. The car ran 12.5@111mph a couple of days after the 280 pull. Dyno numbers don't mean much! A dyno is a tuning tool.
