BAP Questions

[16GoManGoHC2]

100% correct, my 22psi is like a candle burning brightest before it goes out.

Yeah my boost from a 2.4 is just a fart in the breeze compared to the same boost from a whipple

Well my son will tell you 29 lbs from the 3.8 is pretty freaking scary lol Especially with a laptop on your lap, a gauge in one hand, phone in another taking a video and just hearing hell unleashed around you pinned to the seat. My seat belt didn’t want to let me go even, had to unlatch it for it to release me lol

Dual PnP KB BAP worked perfectly. Easy install except for running the boost reference switch wire from the engine bay to the trunk neatly and professionally (which took me 3 freaking hours lol). I changed my mind on how I’m going to run a third pump. First going to try Not going to run it with a FPCM as 3 pumps running all the time is going to put too much heat in the fuel tank. Third pump is going to be a 285 with (check valve) and be switched on at 20 psi of boost and run wide open, the other 2 on FCPM’s will trim the pressure as needed.

You will be in the same boat as me with the 295's, they do not have check valves and cannot be run with a return system unless you switch the primary pump over to a 285. The return system eliminates the FPCM's. you will have to run a Fore controller or a leash.

what injectors are you running?

Not running a return still system, my modified stock fuel line still keeping up just fine. According to Fore running the 2 295’s I’m now running on the FPCM’s (BAP boosted atm) and the 285 with built in check valve to come on while under boost should work just fine. Hate being a guinea pig but I can switch them all over to fuel pump control modules afterwards if needed if this doesn’t work and just switch out the 285 for a FPCM controlled 295 if that plan doesn’t work.
I’m running ID 1700XDS injectors.

So I can tell you from my personal experience, I'm running 3 295 pumps, with a dedicated -10 feed line feeding both rails. I've maxed my 1700's out. I have 2150's ordered. my fuel pressure is dropping to about 75psi when they max out. so we will see how the 2150's do in this scenario. I think to stay returnees I would need to add 2 JMS baps. But that's playing with fire in my eyes.

my other option is to replace one pump with a 285 make that my primary on a Fore FPC. and use the 295's as secondary with a return added. still with running 2 JMS baps. you have a 3.8 so you will make more power and need more fuel than me all day.

So far 2 295’s on the KB BAP are keeping up, injector DC has not hit 70% yet, Fuel pressure staying above 75 psi setpoint to where pump DC has yet to reach 80% even. Full pulls 1-2-3-4 to 150 mph last night netted the same.
You don’t think a third 285 running Full bore along the 2 295’s will equal the 2 295’s running on the dual KB BAP?

I've never run a bap so I cant really speak on them. but it sounds like that bap is saving you big time. almost like your 2 295's with a bap are out flowing my 3 295's.

My first experience with a BAP on a Hellcat but yes, they’re doing the job. BUT the 2 295’s alone almost did it before the BAP. That’s why I’m wondering if at third fuel pump will be enough minus the BAP. I can always put the single 285 pump on a single BAP if it doesn’t keep up.

From your log running close to 30psi on the 3.8 is wild compared to my barley 20psi on a 3.0. What is the altitude and DA where you are? I am trying to figure out how you're not maxing them out and I am.

 

[16GoManGoHC2]

Did a 60-130 pull last night, traction SUCKED, had to leave my underwear by the side of the road after the run lol
Yes, a bit of a down hill slope but only 8-10 degrees of max timing commanded and traction control took it away as fast as it dialed back in
DA and temp on top. Not my best run but based on cold road traction it’s all I was getting lol

 

[RGPIII]

Makes more sense now. That da is insane.

You don’t need to go any faster lol

I have plans to see 2's before the season is over.
