As for recouping my costs i have crunched the numbers and it would take about 2-3 years for me to recoup my money. but i also have the nice peace of mind knowing its keeping my gas fresh, and also giving me more horsepower |
Take in look in my profile and see how I installed mine. Mine is flipped from yours and is over on the shock tower.
I didn't install mine for mpg, but for power. I'm not sure that you would get much from it for mpg (if anything at all) since you really have to adjust your tune to account for the fuel quality change. I didn't just read articles about whether it worked or not, I installed it and had a dyno tune done before and after the Fitch install and we were able to tweak the tune to get an extra 5 hp and 8 ft lbs.
I think we added a little fuel to the ratio and bumped the timing (it was a long time ago). The A/F went weird and went a little lean with the Fitch installed...it looked on the graph like it was oxgenating the fuel somehow. We didn't know why, but it was doing it. As far as the cost of it goes, it's cheaper than underdrive pullies and can get you about the same bump in power.
I am running E10 93 octane which is the best street gas you can get octane wise so if you're running 91 or 87 your power bump (if any) would be less. The power bump was so small, I didn't feel it by the seat of the pants, but the throttle response we were able to dial in is razor sharp. I don't pretend to understand the science of why it works, but I was there and saw the dyno work and results...it's doing something right. Ken @ Modular Depot tuned mine, the tuner that's mentioned a lot in MM&FF and 5.0. He had never seen one before mine and he was impressed with it. These guys run and win NMRA a lot as well as road race and win at that so these guys know what's what. I trust these guys and also saw what happened with my own eyes so I know the Fitch is doing something good...it's just a very miniscule change and not a miracle by any definition.
