Bov stall engine

sorry was caught up in a sudden long meeting, n now back....



other things that need to add or emphasize is that all MAF is not designed to be placed as a 'blow thru' setup, u can try but no guarantee..........however a Hotwire is more applicable for blow thru!! hotwire provides a constant heating to the wire exposed to the incoming air traffic, n when it cools down, it'll need more V to keep the element hot, thus this is how it tells the ECU based on this info.... I might probably need to take back my word on the 'perfect world' in the previous post, so if u placed the VTA BOV before the MAF, the shockwaves travel back thru the MAF to the BOV and this might provide temporary wrong readings, and if u placed the VTA BOV after the MAF, ur still back to square one of sending rich burn data to ur ECU....

if u wanna go for hotwire, get urself an MAF Translator, that's the product's name, there are available kits readily available for mitsu DSM models like ur 4G6x family!! so no problem watsoever....

remember as i said if not mistaken urs should be running karman too, means it's using hertz as reference, n hotwire is using voltage as reference, so the maf translator places a hotwire and translates the V into Hz signals in order for ur ECU to be able to read properly.....

for me i didn't take on this path coz no one in the US is familliar with my GSR 4G9x series and they just told me they can't guarantee whether it works or not, thus not worth me spending some USD 200 just for experiment am I?

Yo kenneth,
I'm quite clear about that now. I did search throught some web, found that many driver did meet the same problem. Not even for only Mitsu car, but other as well even for continental car.

In fact, blow-in is still the best setup for any turbo car. Anyway, I try to find out what is the air flow sensor type that my car is using now. Let you know while we meet. :_:
 
lancerboy,

listen to maxx, he's right, compressor surge will definitely shorten ur turbine's lifespan, remember turbine is designed to have a 1 way air direction and not both ways back n forth....

here's a link for u: http://www.youtube.com/watch?v=Y4bZHpT-L38
if u get this, that's wat maxx mentions upon....

kk,

sure dude, if ur good in electronics, u might probably wanna go for a DIY HKS VPC..... too bad i'm not

Kenneth,
HKS VPC? :emoticon_U: If i can DIY, sure I will... haha

Any progress to your MSII?
 
kk,

ur in the technical field so let's share something, first get a oscilloscope to datalog all data on the hertz values from 500 rpm to max rpm, then get a GM hotwire n do the same thing of coz not using ur car this round but some other method, then get a voltage to hertz converter circuit / schematic, n with some experiment, u should be there....

but remember talking is easier than practical....

it's an ms I, the progress: waiting for the megastim to arrive should be by early next week sigh....

Hey all, my bov doesnt have any fluttering sound at all, i emailed Trust to enquire ans they say even when recirculate, it will produce some sound quite similiar to ssqv
 
lancer,

yep recirculate it back will be the best, u won't lose anything in performance....
 
Hi all,
From this thread, I can make a small conclusion from BOV that we all used.
Lancerboy is using Greddy Type-S BOV which it has re-circulation back to airflow.
Kenneth is using SSQV which has no re-circulation to airflow which same as mine using Blitz BOV.
Lancerboy won't get any problem like flutter sound and Kenneth also won't get flutter sound. And I do have that sound!
Lancerboy will definitely having a good BOV that prevent from compressor surge because having re-circulation.
Kenneth wont have compressor surge because VTA BOV will definitely release all the pressure. But without re-circulation, the engine will have stalling problem.
I will have compressor surge but without stalling problem because my BOV cannot open correctly at low boost and surge my compressor with anti-direction air flow and cause flutter sound.

Wow, I can see that Greddy Type-S BOV is the best for stock setting engine. Agree on that?
 
kk,

ur right i dun use a recirc kit, coz i intend to be a temporary rice boy at the moment (for now-LAR), coz once u add recirc, the sound won't be as loud, and some even went silent at low boost, so no point buying an RM 800 ssqv with less sound, defeats the purpose, but this is subjective, it depends on each individual...

however hks ssqv does have a recirculation kit available, some will go to the extent of making their own recirculation kit, it's just some piping and brackets to fit into the outlet airways of the BOV back to where it's suppose to be, put it short, to make a VTA BOV into a true plumback....
 
kenneth, type S also have birdie sound when re-circulate. unless u keep it soft setting, but i think i got a problem in that.. when i boost, it seems the RPM raise very slowly. i think it leaking?? i am not too sure if it will leak if its too loose.. i try tightening it to a setting with no fluttering sound and it sound like stock bov, soundless. the losser i lossen, the more the birdie sound.
 
Better dont go to soft. Too soft, BOV will open too soon until leaking at certain boosting point.
 
anyone using greddy type S, maybe can verify the ssqv-alike sound coming out from my type S (when re-circulate) is correct?
