I havent seen a dyno chart, but it very well could be in the 20-30 range in the very upper r's......but I dont know what range or if your car even will go that high in the r's without a tune before shifting.........just stuff to consider. I believe this to be a good mod for the NA motors though........but if you dont have a good intake it wont matter because you wont be able to suck enough air for it to work properly and if you dont have the u bend delete done, you wont be able to get rid of all the air efficiently......it will back the system up.........I would do the CAI, the U bend delete and then the HV3 if it were me.......it is your car though.......
