kenny bells stuff looks great,and is a trusted name. How much was the BAP?
Do i need to run a BAP if i change to a 255 l/hr, or is it better to just boost the stock pump. Just about finished with the install, still have to put on Methanol kit,was hoping to get it on the dyno on Friday, But that is fast approching. Maybe we will shot for monday or tuesday. I already have the MSD(Part#2350) but i was told it will not work on the LS1's returnless system.
Do you know anything about it?
Thanks Alot in Advance

The Kenny Bell is made to use on a returnless system, i used it , works great .

You can adjust the amount of power the stock pump sees from 13-20 volts, It comes with a 4psi hobbs switch, which means the kenny bell will send extra power to the pump at 4psi.

I paid $240 for mine
but worth it

I used the MSD BAP before. Worked great before I upgraded the fuel system.

They say it won't work but I have 2 customers that already had Boost a Pumps and I informed them MSD doesn't recommend them but they still wanted installed so I did and tuned. Both are still running with no fuel pump issues. One has been on the street for over a year now as a daily driver. The second one we added a return line and regulator a month ago.
