I recently bought a cartech setup for my fb and I have a aeromotive rising rate fuel pressure regulator (1:1)..... is there any benefit of running this FPR on a drawthrough setup or do you only want one for blow through?

 

im almost positive you only need one for a blowthrough set up. if its a drawthrough the carb wont see any pressure so the fuel delivery wont be impacted. someone correct me if im wrong

 

You're not wrong. The purpose of the boost-referenced FPR is to maintain a constant pressure differential between the fuel line and the float bowl. It's not necessary if the pressure in the float bowl doesn't change. But there's no problem with using that FPR anyway. You just won't hook up the boost reference port.

 

^exactly, i forgot to throw in the last thing you said.

 

Cool thanks guys. Just getting some stuff swelded up on the exhaust and the exhaust manifold and get a o2 bung put in the down pipe.
How far away from the turbo should the o2 be?

 

it probably shouldn't be closer than about 12" to keep it from getting too hot, but other than that it doesn't matter
