Hey guys, i have a mbc set to 8psi,and it hits it for about 4-5.5OOO rpm. but after that i lose about 3 psi, and i run super rich.

my questions are where could i be losing boost?

i have a greddy 15g on a b16a.

my thoughts were get a new actuator?

maybe the charge pipes or intercooler are bad?

wehere else could i be losing boost?

pics here..
thank you.

sounds like a leak.. what are u using as a filter on the inlet?

 

yeah this is the guy runnin sohc greddy kit on a b16a, theres ur first problem....turbo is way too small, and fal out of it efficiency range at higher rpms...

 

That turbo probably isnt the problem, I had the exact same problem when I ran with my S/DX exhaust. My cat was stopped up from a few qaurts of oil.

I agree, sounds like there is something leaking. I have a turbo for a SOHC on my B16 too and it runs out of air, but the boost level never drops, I just runout of power on the top end...

 

nice to see another cornhusker on H.M.T.

 

Nice looking car.. Check for leaks around the couplers. Use some soap

 

thanks for the replys ill check the piping couplers here in teh next few days. its kind of hard to now. since its 2 degrees out. with 6 inches of snow on the ground.
