dsm bov open at idle? ignition timing?
 

heres the deal. ive got two dsm bovs neither of them are open at idle. on my old kit w/ some china knock off its was open w/ idle. i tested on of them and it doesnt open till 27 inch lbs of vac. yes it is crushed. i havent tested the other yet. it blows off with boost but i think its also backing out the compressor housing. the car is only running 8lbs on a 14b hmt style for sure. the engine is a d16z6 w/ the odb0 modified dizzy. my next issue is all i can get for timing is 7 degrees btdc. anyone else have this issue. thanks

if you hear a fluttering noise, than its possible that some air is going back thru the compressor. my 1g bov is open about 1/2" at idle. also, any sort of engine management relies on 16* btdc so if you can only get 7 than you're either A) not making the power you could be or B) driving around a grenade

so you saying that it being that far retarded will blow it? i dont see why. i know it can make more power. plans of odb1 conversion is in the making. car is pulling strong as it is

ign retard=runs like ----, not making power
advance= ping, boom

exactly what i thought..... well we just took it out tonight to run and tood a porsche boxter by 3-4 cars. ill try to get something on youtube once i figure out. keep in mind this is a 200 dollar turbo kit at 7 psi on a vafc hack

boxters are slow as ----, i took one in a stock vr6 gti.

well by what i can find they run a 13.8 stock. granted it was a roll he would jump harder on a dig. it still a good win. gti's on the other hand are junk

grind out the upper bolt hole on the dizzy so u can rotate it towards the windshield. or away from the bumper. then you can adjust the timing fully

my dsm is open at idle. just a tiny bit. its not crushed
