Re: Flowmasters
Sorry for the delay. I have my kids for Christmas and we're on the go.
Hib, the car was totally stock. It was dyno'd about a week apart. The values were SAE corrected. Stock dynos were done six times and they never varied more than 2 hp. The modified (exhaust only) dynos were done six times and it gained about 2.5 hp per pull. After six we quit. I drove it straight from the muffler shop to the dyno. The temp varied slightly but I don't remember which way (1st to 2nd). The water temps were fairly controlled but it climbed as the day went.
