Confused About Bov Setup.

[96gstdsm]

Ok i have read a bunch of the old threads about seting up an aftermarket bov to vent to the atmosphere but still a little confused. I know that everyone will ###### bash the idea as seems to be the case in the past. I want to get one like the hks ssqv so i can either recirculate it or vent it. IS all i need to get the gm 3 mas and a maft? I know that is an expensive mod just for some noise, but hey i does soung great i think and i need to replace my stock bov anyways and with the hks i can choose to recirculate as well. My car is strictly a daily driver. I dont want to have to deal with the running rich between shifts etc and bad idling and stalling problems. The gm mas and maft would fix that problem and allow it to run the same as stock besides the venting and a little slower spooling?
If anyone has any knowledge into this please help me understand what steps i need to take in order for it to be a stock feeling setp plus the pssshh.

Thanks. --Ryan.

Ps for short term just to install since my bov is bad the 1g bov is a direct bolt on or no?(not to vent to the atmosphere)

You also need an intake set-up for it. Do you really want to vent that bad? You could spend the money elsewhere and get better performance out of it.

 

[elfroggo]

1g bov is not direct bolt on you need an adapter. The EVO bov is direct bolt on though.

no you don't need a different intake, you can just leave your maf unplugged, it'll be an uneeded restriction in the intake but if the emphasis is on noise you should get a hard intake, then you get the cool turbo whine too... Maybe to stay all stock you could get a 2.5" GM maf and put it right into your stock upper IC pipe, you would just have to cut a small piece of from the flex hose and use 2 more hose clamps to secure it, that'd be the easiest way.. has someone done this? I bet it would work.... if not you'd need to buy an aftermarket upper IC pipe ment for the GM sensor, like this one: http://www.dsmtuners.com/parts/product_info.php?cPath=3_146_54&products_id=726.. I say just pull off that flexible tube that attaches to your throttle body, measure the inside diameter, then call a wrecker and ask for a 2.5" GM maf, go there and measure the outside, see if it's do-able.

ok sounds good, is getting a maft and gm mas going to be more reliable of a set up? I already have an aftermarket intake setup.

I am not doing this right away, as i am in the process of doing some performance mods first. But i am not building a race car, so i would like to have that bov sound as pointless as it might be. I have always liked that sound ever since i first heard it on a car a long time ago, this is my first turbo car so i figured i would get that.
To prevent my car from running rich between shifts and bad idling i would need to get a maft and gm mas correct? for the best results? I dont especially want to start cutting away piping and i am going to be replacing the ruber tubing with all hard pipes.

Do not leave your maft unplugged. the car will not like it. and will stall out.
Just recirculate. EVEN with the new bov it will be loud. Until you get the Gm sensor dont vent.

 

[VanIsleDSM]

I've never tried, but why would it stall out? it's just essentially part of the intake when unplugged no? if you're getting hard pipes then just make sure you get an upper IC pipe for a gm sensor

 

[grnchevyz]

I think what VPrime meant is if you do not have a GMMAF/MAFT setup, do not unplug your MAS as it will make the air unmetered and the car run pig rich.

Pretty much your best bet is to get a 1g BOV and an adapter recirculate but do the dump tube mod on Http://www.plymouthlaser.com . A GM maf is going to do nothing but give you a headache because you have no other mods according to your profile. Trust me, I rund a 1g BOV with a stock intake pipe and the dump tube mod and my Blow off is still loud enough to scare the shit out of any Honda Ricer on the road. This subject has been coveren 8,457,632 times on this site and the general consensus has always been bolt on a 1G or a greddy and be done with it.

I personally have the HKS SSQV vented with Blow-Thru setup GMMAF/MAFT and it is loud as all hell HOWEVER, buddy of mine has a Greddy Type-S on his 91 Supra and I must admit the "digital" sound is wicked. Almost makes me think of going Greddy now

 

[96gstdsm]

So what do i need to attach a 1g bov? Is it weld on only? Cause i am buying a fmic not too far down the road. For now i just have soft piping an the stock 2g bov, but it really sucks and seems like it is leaking the whole time.

And i need to get one thing cleared up, if i do get a gm mas and a maft will i be able to reliably run a bov vented to the atmosphere? Or will it still run rich or stall out? If it will still be a hassle then i would just get a 1 ###### or an hks and just recirculate it.

Do you have any problems with daily driving with your gm maf and maft set up? Does your car run rich between shifts? Or is that all fixed when you install them? Are there any downsides to doing that besides the fact that venting is always worse than recirculating?

 

[grnchevyz]

I have the GMMAF/MAFT setup tuned with DSMLink so I have no issues with rich between shifts. You will need a logger and spend some time to tune your Blow-Thru setup until it is satisfactory othwerwise you will have issues.

Could i use the apexi safc-2 to tune that setup and prevent any problems running rich? I am planning on buying that as soon as i am able.

 

[grnchevyz]

Yes but you will also need a datalogger (odbloggers.com) or equivalent to ensure all your settings are optimal. Otherwise you will be tuning using the "by the seat of your pants" methos and in my opinion are only looking for problems.

Ok thanks alot. On a side note, i see that you have the evo3 16g turbo. I am planning on going with that one as soon as i finish all my supporting mods. How is that setup for you? IS it pulling hard to redline? Thats what i hate most about the t-25 just dies out on me completely. Is the gas mileage much worse with the 16g? At 10 psi on the evo3 is there more pull than the t-25 at 15?

Thanks again.

I've heard the HKS recirculated and it's still loud as hell. I would try this first as it is the cheapest way of doing it right. If it's still not loud enough,then you could move on to the gm maft setup. I have hard piping with my stock 1g BOV and it is very audiable. Doesn't have that greddy or HKS sound, but still sounds real nice.

I've got 2 tunes on my E316G. 14psi and 21psi. Both pull hard to redline. I love it at the moment but probably will head towards a 20g to hit the 400hp mark next spring. On a good tune, you'll love that Evo3.

Ok thanks alot for all the help.

In regards to a 1g bov. The flanges that they sell for that bov on a 2g could that be ptu in the rubber pipe? And just tightened on? Thats what it seems like and then bold the 1g bov onto the flange? Basically the same way the 2g is right now but with a new flange and bov.
I decided to go with a 1g bov i think atleast for now just as a cheap solution. I am bidding on one right now. What is a good price to pay for it?

Here is the link for that http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=011&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=320037740867&rd=1&rd=1

Sorry dont know much about the bov. The larger tube sticking out that is what i connect the hose to recirvulate it right or wrong? Is there anything else i need to get so that it would work on a 2g?

 

[Rice Over Wheat]

Do not leave your maft unplugged. the car will not like it. and will stall out.
Just recirculate. EVEN with the new bov it will be loud. Until you get the Gm sensor dont vent.

...I can attest to this. I was changing out my intake pipe at a shop, pulled out onto a fast road and couldn't go faster than 5 mph! I was like oh shit, wtf! Thank goodness there was another re-entry point back into the parking lot 20 feet down which I limped into. Pulled back in front of the tuner shop and saw that I forgot to connect the MAS plug as well as the two lines off the intake. Could have been worse if there was traffic when that happened, instead I just looked like an ass.

 

[96gstdsm]

Ok i decided against venting for now and purchased a 1g bov from ebay(link above in previous post) I am also going to buy a 2g, 1g bov adapter flange. Would i need to get anything else to recirculate it properly? Does everything else mact right up with the same hosing and such? This is the flange i am talking about. Does this just fit right into the stock 2g rubber piping?

http://cgi.ebay.com/ebaymotors/BOV-...017QQitemZ270025970405QQrdZ1QQsspagenameZWD1V

Also if anyone knows of a cheaper flange i could use that would be direct attachement to stock rubber piping please let me know. I plan to get hard piping soon but for now i am going to use stock.

 

[speedy13]

RRE can sell you the flange for alot less. I got mine from them. You will have to weld this on. Any exhaust shop will do it for cheap.
