how to make turbo spool quicker...
 

right now i'm running 4/4.5 psi on a y7 with a 14b on a hf mani. i hit full boost at 4k rpm... i'm thinking it should hit fool boost sooner. is that about right? or are there any other way i can make it come sooner?

Sounds like your waste gate isn't shut all the way out of boost.

running such low boost causes the wg to open more at low rpms; that will let exhaust by and not give the turbo enough to spool

run more boost to get rid of the lag or get an EBC

even just a mbc will help spoo faster. if you can get it set at 4.5lbs idk how low you can get the spring in an mbc set at. but that ball won't move until 4.5lbs which will help eliminate your flapper opening "prematurely" lol

Nitrous.

i'm not using the original wstegate. i'm using a carb spring... ::)

Re: how to make turbo spool quicker...
 

Hmmm, maybe the carb spring isn't holding the wastegate shut tight enough. Sounds like it's doing it's job and limiting the ammount of boost you make, but with a small turbo like the 14b you should be boosting sooner. Maybe there's an exhaust leak at the turbo-manifold gasket.

stop now...


this forum really needs a :tard: smiley

Jeff did it before.


Anyway, how is ur exhaust size (exhaust, cat?, downpipe)? is the HF mani/exhaust housing ported? Check for exhaust leaks on the mani/adapter/turbo. When I open my cutout my 14b spools like nuts. And gets really loud/cool sounding. I have a 2.25 exhaust with a testpipe.

put more tension on your spring(move your mounting point of the spring farther away). be careful not get a surge!
