Why Run a Dual set up?

[Titanium-99]

I was just currious what is the advantage of running a dula BOV/BPV set to recirculate? I currently have a HKS SSQV BOV tha I am directly recirculating into my AEM CAI which has helped a little with the performance and driveability of the car but I am still having stalling issues and my RPM's dipping below idle but they quickly come back sometimes and the car wont stall and again sometimes it does. I am also running extremley rich which I think has something to do with my BOV. Now If I had an adjustment screw on the back of my BOV then I would just adjust that untill the problem went away, but my HKS BOV is the new style one with out the adjustment screw. My BOV is currently located on my cold side pipe but I am considering moving it to the hot side pipe because I have heard that could also fix my issue. Any advice or infor mation would Be greatly appreciated.

thanks

wow that is quite the list of mod u have there and i don't believe there is any advantage to the dual setup besides the old style of driving back... ZOOOOOOM (OH s*** COP) BRAKE!! and no stall lol! but here is a free bump for a person who may know better than I!

Believe it or not, the dual setup worked better for me even with the MAF relocation. Without the diverter valve, the turkey came back no matter how loose I adjusted the greddy bov.

i have the hks on the hot pipe and i am having the exact promblems u listed.

I just relocated MAF to Cold with single Greddy BOV setup. I had to take inner spring out of BOV to completely get rid of turkey. The BOV dumps kinda early now but there dont seem to be any leaks.

I don't need a dual setup. I am just running a greddy type s venting with no bpv or anything. I have stalled maybe twice in the last six months and maybe a total of 5 times since I installed my hi boost fmic kit 15 months ago. I tried to recirculate and that made it stall a lot. Granted I have some turkey under light throttle and letting off but the car runs great. Maybe try venting it and tightening your bov. I don't know but it works for me.

I have tried a vented Greddy Type S on the Hot Pipe and got the same issue. Stalling after boost, and running rich as hell. I am getting a Aluminum Hardpipe soon with a HKS Flange welded on for a Dual Setup. Apparently this removes the turkey and stalling issues. I'll keep ya posted on when I do the install.

im running the turbo hoses hard pipes and a real hks ssqv bov with the diverter valve in stock place ...dual setup and have not had a problem thus far

So you were running a dual setup and took out the bpv leaving just the Greddy, and your turkey came back??

I have a dual setup currently (hotpipe-->bpv-->injen and greddy venting)and with the relocated MAF I thought I'd be able to remove that bvp all together with no adverse reaction ?? Sounds like that's not the case here. How is your car running and can you post a photo of your setup?

if im not mistaken arent you supose to put the bov before the maf when its relocated?

Correct, Tallard's pic has it in the right spot.

 

[tallrd]

still looking for an answer. I'm thinking of removing that bpv all together and just running my single bov venting.

Will the car run well given that I have the MAF relocated? Anyone know from personal experience?

I don't know from experience but from what im told, if you move the MAF to the cold pipe and mount the BOV before the MAF then you won't have stalling issues because the air metered through the MAF is still Correct. Basically your tricking the car to thinking you aren't venting a BOV. Keep in mind that doing this can possible lessen the life of the MAF. I don't know if thats a proven fact or not, but it has been discussed. If anybody has any experience with this please correct me if i'm wrong.

 

[tallrd]

I appreciate the info, but I crossed that bridge a while ago. I've had my MAF relocated for some time now. My question is if I can remove the recirculating bpv from the equation and just have the bov venting considering that I've relocated my MAF.

Am I going to be the first to try this??

Check that thread.... yes its very long, but the answer your looking for i'm sure is in there. It's a sticky from the Forced Induction section.

ive seen plenty of cars where the maf was relocated. all of them seem to run fine with no dipping or stalling.. i had a forge on mine with stock pipes and everything but i had some dipping. so i went back to stock and im returning the forge because i need money to get custom hardpipes i am having them relocate the maf

i know that you guys are running a blowthrough setup on the MAF i was just wondering...do our cars have a 2 bar maf?i'm throwing on a stock srt4 ic and sprayer, and my shop is making my pipes. i dont want to relocate maf if it's anything less than 2 bar.

i have heard that relocating and then running venting bov can damage the maf, but i asked around at my tech school and everyone i talked to said that's not the case. no one even had a good reason why it would or how it could possibly damage it.

 

[Bakum]

I have yet to read about anybody who had to replace their MAF because of relocating it, so you're probably right. Tailord I think his name is has a thread about purchasing a Blow by MAF just in case the Stock one went bad. I'll see if i can find it.
