At what point is a BAP required?

[JBZL1]

Hey guys, I'm just putting a list of parts together and I've been searching this with no definitive answer. Here's my mod list

Rotofab CAI
2.55" upper , ported inlet
SLP 1 3/4" long tubes, catless
Colder plugs, 160 tstat
Id850''s
Afco HX, rotofab IC reservoir
10.4mm wires

And once I get the injectors I will be getting a custom tune. Will I need a BAP? I don't plan on doing anymore mods than these, not a cam or anything. Will I be OK without a BAP ?

Thanks guys

There are different opinions about the exact point that a BAP is needed but with those mods I would say no. Most people agree that it's needed somewhere around a cam and 28% overdrive or 31% overdrive and stock cam and you will be at 18%

You need a BAP if your fuel pressure is falling. Check fuel pressure at WOT all the way to redline. If it doesn't hold 65 psi then you need a BAP.

Don't depend on anyone's advice on a forum. Check your fuel pressure.

Can u plz explain more about this method? As I'm planning to a add a BAP to my build but shops have different opinions about this.

I think what Bryan is saying is you need to monitor your fuel pressure during WOT so you can determine if your fuel pressure is dropping below 65 psi. You'll need a gauge or tuner to monitor/record.

Yep, you can log fuel pressure with HPTuners or another scan tool. Or get a fuel pressure gauge and duct tape it to the windshield at see what happens when you get close to redline. Safest way would be to watch it on a dyno.

I had to deal with this back in 2013 when I upped the boost with a 9.55 pulley.

Bryan is correct. The only way to know is by logging fuel pressure with a scan tool. FWIW mine was fine until I went over 628 rwhp. Once again, you need to monitor fuel pressure, but that is when I started having the issue.

If you do find you need a bap, I am in Ontario as well and I have a Kenne Bell I used for 3 months that will be coming off. It will save you some money buying from the states

What all is involved with installing one of these?

Thanks for all the info guys!

The JMS unit is plug N play. It's what I use. It uses an inline harness for your throttle pedal. Simply run the wiring under the carpet to the trunk. I mounted mine in the battery area. You can set it to activate at whatever throttle pedal voltage you like.

Thanks a lot Bryan, u truly are a knowledgable member here and as always helpful when it comes to our questions sir.

One of the shops here in UAE recommended that I buy one, the other shop said no way that u will need it and if u end up installing one it will damage my fuel pump in the futur , what do u think? Have u heard of such a failing fuel pump due to using BAP?

The idea that boosting the voltage to the fuel pump will cause it to fail is false. In fact the opposite is true. A fuel pump struggling with low voltage will overheat and fail.
