Here's the deal everytime I floor the gas pedal on my b16 turbo powered rex it bogs out really bad. But if I just accelerate gradually it's fine. I took my car to get dynoed a while back and I thought it would solve the problem but guess what it's still does the same thing. A few things that I can think of are replacing the the fuel filter, bad vacuum routing, and it could be that the sohc ported turbo manifold is still just to small and it's causing the engine to choke out. Any info will be appriciated thanx. One more thing there has been no codes thrown.

 

b16 sohc??

 

are you sure its a b16 sohc????

 

how about a pic of this engine

 

Are you sure you're not detonating?

 

I think he was trying to say that he has a B16 dohc with a sohc turbo manifold.

Thank you. And no it's not detonating no pinging what so ever. It runs good and all but like I said as soon as I floor it, it just seems as it wants to turn off it boggs that bad.

 

What size injectors and what fuel pump? I'm assuming inline and 12:1 fmu? Any codes? How much boost are you running???

 

I'm running 450dsm's, Walbro 255lph intank fuel pump, apex'i v-afc, and b&m fuel pressure regulator.

 

I'm not familiar with setting the afc, but I would maybe try getting a wideband on there and playing with the settings. Or you could just sell it all and get a standalone

 

Well the v-afc is tuned already it's just hard trying to find what's causing it to bogg so bad.

 

my guess is... its not too rich, so it must be... what gear are you in when you punch it? or is it off the line too? what are you afc settings as well.

 

make sure the fmu sees boost, iv seen poeple hook that up wrong. it would bog if not correct.

 

It boggs right off the line. And as far as fmu i'm running the v-afc with 450cc injectors.
