Does anyone know what kind of power a B1-B2 setup can handle or how reliable the setup is. I mean will they handle up to 600 or will something bigger be needed.

 

IIRC

Olie poole, from powerbypoole.com has a couple of trucks with that setup that did turn over 600 with the right injectors and boxes.. I know for sure an SPS62/14 over an S400 will be over 600 with the right setup, heck even a set as small as the BD twins will do it, Look at RJohnsons ride, 632 on BD's! cant beat that with a stick

I have an 62/14 over a S400 (basically a b1/b2), with over 30,000 miles and over 600 1/4 mile passes, without any problems at all. Very durable/reliable setup. I am over 600hp, and there is air to spare. It's a hard combo to beat. Lots of people on here are running them.

My buddys 01 is putting down 617 with a QS B1 on top and a b2 on the bottom,spool up with a DD cam is as good or better than a stock hx35.It spools 3x faster than my hx40/ht3b PDR setup.
