problems with Perrin install.. FMAI, CAI, and BOV

[butter5784]

I installed a perrin FMIC, CAI, and BOV (ven to atmosphere). After the install while sitting in the garage it started up and idled smoothly for about 10 mins. Durring that time my brother-in-law checked for leaks, and anything else that looked wrong. Everything looked great. It even sounded good. I backed it out of the bay and put it in first and gave it some gas. it then started idleing very poorly. It would go to 1200rpm and thatn almost to 0rpm. After a few times it would just stall.

I called perrin and discussed the situation with their customer support person. he said that the car won't work on the Vent to Atmosphere BOv and that I need the Recirulating bov. This upset me because I had spoken to three other people there and confirmed that the parts I purchased were the correct ones ( one of wich was a "tech" ). He stated that there was nothing that could be done and that i could talk to a manager on Monday to discuss a remedy.

I called back after taking his advice to disconnetd the BOV and let it idle a few cycles to get the computer to adjust to the modifications. this was usless. I asked him if the oil from the fome filter could be the cause perhasps it had transferes to the MAF sensor? He said no, and that the instructions with the filter said to remove excess before installation. (which it did not0

Well basically my wife is upset and i have to get her car working properly asap. I'm also venting a little because i'm pissed that this all happend. If anyone has any ideas of things i may be able to try or if anyone had a similar problem, please let me know.. thanks....

Most people have stayed away from the Perrin SRI because of stalling and bad idle issues. This thread is a little old, but it might help you understand your problem: http://www.msprotege.com/forum/showthread.php?t=85255&highlight=perrin

Also, VTA is a no no unless you relocate your MAF. I would do some searching on the forums for these issues, there are alot of threads on it.

[butter5784]

(dunno) i asked people in this forum when perrin told me to use the vent to atmosphere and they told me there were several people running vent to air without stalling issues. I have no idea what it could be.

Perrin suggested i take the Bov out of the loop by diconnecting the hose at the top and capping it. since it didnt change anything they swore it's not he BOV.

[evilmonkeyMSP]

they most likely had relocated MAFs

[crashkelly]

you can vent to atmosphere fine with the dual BPV/BOV setup...I have been researching this heavily because i am going to run this setup. And i have never had any problems with the perrin SRI originally i thought i did because my battery terminals were too big for the battery someone had in the car before i got it and they would cause stalling because they would shake loose. But after getting better ones i never had a prob with the perrin intake...the most important thing about that intake though is to make sure the little L shaped piece that goes into the intake with the hose that runs to the BPV is pointed towards the turbo with the open end.

By the way where is your BOV I didnt see where you mounted it in the picture...according to 505Zoom who is a god with this car as long as you run the stocker BPV the way it is normally setup and run the BOV with a different vac source (ie. brake booster line) than the BPV it will recirculate with the BPV and vent to atmosphere with the BOV. i'll pm you with a convo i recently had with him about this.

[crashkelly]

and you can relocate your maf but i wouldnt just because you are pushing such high pressure air through it...but some here have had no issues with it breaking or anything so its just a risk you take.

[evilmonkeyMSP]

yep, there are people on here that have had the MAF relocated for a few years w/ 0 issues....

yeah with great success from what i hear. Its just one of those risky things though...with our cars some people could run that way for 10 yrs with no prob, but someone else might have their maf blow in ten minutes!

[butter5784]

I really appriciate all the ideas. When I bought the car it had an aftermarket fmic already. It was crapy so I bought this thinking it would help. the bov is connected on the tube going to the throtle body closest to the FMIC. I don't have the factory blow off or I would try using it. It doesn't make sence to me because the crappy peice that was on there before at least ran. this one was 1400 and won't get me 10 feet.

[butter5784]

Oh yeah here's a better picture with the BOV. It's just to the left of the filter

http://www.msprotege.com/members/butter5784/100_6093.JPG

[crashkelly]

oh that sucks...without buying another BPV you will have to get a recirculating adapter for your BOV and run it into your intake.

[crashkelly]

the black thing is your BOV...what is the blue Perrin thing?

[butter5784]

The directions sucked only thing it said to plug into the intake was the tube going to the crank case. i put the cone shaped.. (i think it's a temp sensor) in the one hole and uses some fitting it cam with to cap off the largest hole... I'm assuming that's were the recirculating bov hose would come back and hook up. but the directions didn't even mention it. I'm very dissapointed with their directions..

[crashkelly]

ohhh its the cap for the SRI

[crashkelly]

yeah you are exactly right...thats where youd recirculate to

[butter5784]

is that where it was suposed to go ? I couldn't figure it out


i asked and you had already answerd .. thanks...


so you said I need to turn that so it's facing the turbo ?

[crashkelly]

yeah thats a plug so you do just have an open hole in your exhaust...if you had the stock BPV instead of a BOV you would have the exact setup you have now almost but you would have another tube going from an opening in the BPV to where that plug is now and it would cause the blown off air to "recirculate" through the intake which would keep your maf from causing the stalling.

[crashkelly]

Well you would want it to face that way if you were recirculating...it doesnt matter right now because its just plugged.

[crashkelly]

unfortunately i dont know what the easiest way to solve your prob is...maybe someone can jump in and help me...

The best thing i can tell you is you'll either have to replace the blow off valve with the stock or an aftermarket by-pass valve and get that tube plugged into the intake again.

That or you can get a BPV and run the dual setup so you can still have the nice swooosh sound the BOV will bring.

The cheapest thing is probably to get a recirculation adapted for your BOV, but i dont know if all blow off valves have those accessories...take a look on www.perrinperformance.com and see if they have an adapter for their BOV.

[butter5784]

thanks.. well it sounds like everything is good on the install. I still don't think it has to do with the bov because it's not idleing right without anything happening with the bov. There's no boost accumulating to cause it to open or cause any type of release.

[crashkelly]

sorry man i just looked...they offer a recirculating BOV but its over 200 bucks...look in the for sale section of the forum and you could get someone elses recirculating BOV or try to get someones stock BPV and run the dual setup...sorry you had these probs thats ashame you have to deal with that shit

[crashkelly]

no it definately is the BOV...it doesnt matter that there is no boost going through it...for some reason if you arent recirculating it acts like that...i just took my recirculating tube off my stock BPV and turned the car on...the car runs but the idle drops all the way down to almost stalling.

This BOV thing is a really common prob on this forum and i will bet any amount of money that you did the whole install correctly and that it is just that you arent recirculating.

I wish some other members would jump in on this because i would bet my unborn childrens souls that its the BOV....Do a search on BOVs and check out the discussions that people have already had, i think it will help you.

[Ryoga28]

Everything looked great. It even sounded good. I backed it out of the bay and put it in first and gave it some gas. it then started idleing very poorly. It would go to 1200rpm and thatn almost to 0rpm. After a few times it would just stall.

Are you sure there isn't a vacuum leak somewhere? Is the hardpipes on tightly? intake? I would double check every hose again.

Did you try to tighten the BOV adjustment?

It just sounds like there is a major vacuum leak somewhere.

[crashkelly]

yeah that actually should always be the first place to start...spray some carb cleaner around the connections and if the rpms jump you have a leak, but barring any leaks i gaurentee that is a bov prob

[crashkelly]

...if all else fails you could always check your spark plugs too...that can commonly cause idle probs if they are fouled or just too old

[butter5784]

Tomorrow I'm going to check it all out again. We ran out of time in the garage today. Hopefully it's just somthing little. We'll see. maybe this is a leak that wasn't there untill we backed the car out of the garage. i hope it's somthing small like that. I really want to get this all runing. It's my wife's car. She''s upset because she wanted it profesionally installed but i know it would have been expensive and it's not suposed to be difficult at all...

I hope it works out for you and isnt anything that is gonna cost much time or money. Good luck fella!

[cmahlig]

its the bov, nothing wrong with it, gotta dual vent. you have to recirculate unless you move maf. youve got the bov in the right place, but you need to keep the another bpv recirculating

[butter5784]

any other ideas ?

[crashkelly]

1 - check for leaks
2 - check plugs
3 - move to dual vent or BPV set-up

...i think that covers it...good luck

[butter5784]

Ok, I found the leak. It was located right at the throtle body. After letting it sit because I flooded it trying to start it so many times, it finaly started.

My wife drove it around the parking lot at about 5 or 10 mph and it was fine. We then proceeded home from the garage. On the way home everytime boost would start to build it would start bucking and want to stall. The RPMs would drop and than it would level out. I limped it home. Now it will sit and idle fine but when you rev it up to about 3000 RPM and let off it drops and almost stalls and slowly brings itself back up again. I have tried letting it idle for a bit and turning it off and than back off thinking the computer may have to reset or somthing.. I'm not sure.

By the way, I now have the BOV disconnected so it can't be the problem.

[butter5784]

anyone... I'm stuck here.

[butter5784]

First I want to tank everyone who made suggestions.

Secondly, I want to appologize to evryone who made suggestions for not listening to your advice sooner.

Well, after a weekend of headaches I finnaly took the advice I received in this forum. I relocated my MAF and the car runs great. I was a little depressed cutting the brand new pipe to relocate the MAF but it worked so it's all good. great even.. thanks again

[HighwayUFO]

Did you relocate the MAF sensor to the intake piping? I have been told to do this as well, and that once done, will remove any stalling.

[butter5784]

I actually relocated it just before the throttle body. It runs great. No stalling at all. Before when you drove it you were thinking in the back of your mind the whole time about when the next time it's going to stall will be. Now, it just feels right. It drives like a brand new car. It's great.

[HighwayUFO]

I really need to relocate that bad boy!

[butter5784]

Yeah, it only took a few mins to cut the pipe and move the MAF. It made a world of difference. I'm just not happy with the BOV. It's not loud at all.
