I was a little over 10.5 pounds of boost. I will have to talk to my tuner about wiring the BAP tis way.

OK so we have same boos too then haha.

So we have identical setups.


I was considering the BOV you have too, its either gonna be that or a big red. How do you like yours compared to a big red?

Have you ever heard a big red in person?

I have not heard the big red in person, just on Youtube. Mine is loud as you can hear on the video. Whenever I pull inot a gas station or store people turn around. Some look annoyed, but a lot smile. It does draw attention. At first it was a bit distracting, but I got used to it. Car sounds like a jet really....haha

dwtjr3

Awesome, I may have to go that route.

The sound you had in the video is the sound I am looking for.

I want a obnoxiously loud BOV haha.

Haha...then that is what you will get. My tuner has a BAP for sale that came off another car so we are going that route. Should help a lot in keeping me from starving the car from fuel. More to come.

You should be fine with you fp then

I have a svt focus pump with a bap n I have plenty of fuel for my hp level.

But I have a 340lph pump sitting at home to be safe.

Since a few of you were wondering why I would be out of fuel after this dyno tune as apposed to before I thought I would ask my tuner the same question since I was a little curious myself. Well this is his response.

"Back when we first tuned your car we had seasonal gas. It was tuned on straight gas which has a stoich point of 14.7. Gas with 10% ethanol drops the stoich down to 14.08 requiring more fuel. When we would go for a full pull on straight gas, we wanted 11.7 afr now with ehtanol in the gas we need 11.1. This takes more fuel making the pump work harder. Also you have upped the boost a little which also adds to strain on the pump because it has to overcome the increased pressure in the fuel rail at the higher boost level. So it is a combination of the two things, higher boost pressure and less energy in ethanol blended fuels. Before, you were at 100% duty cycle or nearly there at the end of the pull. Now you are out of pump at 5600 rpm, pressure starts dropping soon after"

This is why I like and trust this guy.

Seasonal gas? What the hell is seasonal gas? I like the lengthy and well thought out response though! I'm still not sure who's going to tune my car yet. There are a couple shops around here who specialize with mustangs...

Good deal on the BAP. How much?

scooter3

Haha...figured someone would ask that. During the summer months they would do a blended gasoline due to the temps here in the SW. Had something to do with the evaporation rate which caused more pollution then normal. They would switch this back and forth from winter to summer. Now we just have fuel with 10% ethanol. As far as the BAP I am getting it for $125.

Is that with all fuel stations or just this tuner? Cool!

I like the idea of a BAP. Seems like people don't really have issues with them.
