Bap and lower pulley ???

[BTS]

Hello SVTP , my question is what is the correct part number for the Kenne Bell BAP on my 03 Cobra , I have search and coming up with 3 different numbers ,my 2nd question is since I upgrading my Heat exchanger and tanks , will it be safe to go with a 6lbs lower pulley or should I stay with 4lbs ...
THANKS IN ADVANCE ....

What is your current setup? Do you have a ported blower? Do you already have 4# lower?

SLP LM ,MAC X PIPE, K&N Intake ,2.8 pulley, SCT tune Ported blower on order and no lower at all

I'd hold at 4# lower with that combination. You should also think about larger injectors and a larger MAF. You want the 40 amp single BAP.

Ok thanks I am willing to go 2.93 with 6lbs if I will benefit safely for more power , but if 2.8 and 4lb is a winner then I will build with that , here is what I'm seeing for part numbers
KNB KB89072 single pumps
KBL KB89069 dual pumps

You have dual pumps so you want the BAP for dual pumps.

A 2.81 w/ a 4# lower is basically the same thing as 2.93 w/ a 6# lower

You have dual pumps so you want the BAP for dual pumps.

The BAPs are for single or dual FPDMs. The 03-04 Cobra have a single FPDM while the GT500 has dual. We need the single BAP for dual pumps (KB89069) unless you upgrade to a dual FPDM system .

You will definitely need injectors. I'm at 100% duty cycle with my setup, tuned by Kurgan.
