MAF Relocation

[protegerider]

all the recirculation piping??????? its like 4 inches of 1 inch black tubing that you cant even see. the point i wanted to make is the car runs much better when the bov is recirculated rather than the maf relocated. its not ment to be there and quite frankly it shouldnt be there.

Okay... so all you're doing is recirculating, nothing special. Sorry to come off as an ass but what you did is nothing new. You are not "solving the problem" because relocating the MAF is for people who want to use blow-off valves that vent to the atmosphere. I'm sure if the original poster wanted to recirculate he wouldn't have made this thread. For what it's worth, I think all the recirculation piping is much uglier than two extra couplers.

Thank you. I 100% agree. It looks smoother without all the extra piping.

yes the car will run better since it was designed for recirc.. the purpose of the BOV is to relase the excess air that wasnt sucked in the TB during acceleration, if you want to do it your way.. why waste the money and get rid of the stock BPV.. relocating the MAF to a better spot hurts nothing, as long as the maf is picking up signal to relay to the ecu.. if you relocate it.. and dont like the way it runs.. get a piggy back of standalone and tune what ever you dont like away.. thats the good thing about those.. you can alter the signal input, thus allowing everything to run more smoothly

no one answered my Q yes. Relocated MAF within 8Inches of the TB, is that a bad idea?

Second question, iv got the SS AFC installed with the stock super map. can i just leave it as is with the MAF relocated? Im montreal there is no really good place to get it tuned, and im not sure if im qualified to do that.

8 inches will be fine, geez, it's not like your car isn't going to run. All these distances are just other members speculating anyway. My MAF is about 8 inches from the TB and the BOV is only about 6 inches in front of the MAF and everything is just fine. Supermap will also be fine - I have a relocated MAF and the supermap was too rich, but safe. Even so, if it isn't fine, then tune it. Chances are any tuning shops will not be familar with the SplitSecond R4 Software anyway. You guys are taking this stuff way too seriously...

I'm glad you think that. There are however, many members here that will disagree with you and I am one of those. I am running a VTA BOV with a relocated MAF and everything is just as good as before. I'm glad you think you know what's good for everyone here though

Obv the car is not going to stop working. But if there are drawbacks to putting it too close then id rather know about it now. and make the effort to keep it at a good distance.

When you relocated yours did you but the reloc-kit. or did you just get some normal coupliers and free-style it.

Took the pipe, measured the distance needed, taped off the areas and cut with a circular saw. Buy two 2.75"-2.5" reducing couplers and four t-bolt clamps from www.siliconeintakes.com and you'll be good to go.

BTW, the MAF just doesn't like too much turbulence. I really don't know why people say not to put it too close to the TB (honestly, how close could you put it?). Just try to avoid putting the BOV right in front of the MAF and having severe bends around it.

Did mine the same way. I can't see what a receirc kit would consist of besides those unless it also supplies a hard cold pipe.
One of the reasons my BOV is living on my hot pipe is to eliminate the turbulance going to the MAF.

can you explain what you mean by "Turbulance" I would assume that you mean when the BOV opens there is unstable amounts of air passing the MAF. but thats just a guess.

Turbulence: http://en.wikipedia.org/wiki/Turbulence

The MAF wants to see smooth, straight-flowing air (which is why it has the air-straightener grating in front of the filament) so obviously any deviation from that has the potential to cause issues. When the BOV opens the flowpath of the air changes so you can imagine the airflow is no longer a nice, steady stream. It has nothing to do with the amount of air passing through it. The idea behind putting a VTA BOV far upstream from the MAF is that any disturbances in the flowpath caused by the opening of the BOV will be smoothed out by the time the flow reaches the MAF. Ideally, if your BOV stays shut at idle (my HKS does) you shouldn't have a problem no matter where the BOV is (mine is only about 6 inches upstream of the MAF).

i see, i see. a lot of people toss the BOV on the Coldpipe. Very few have it on the hotpipe. Is there a reason for that. Is there something about the hotpipe that makes is less ideal for a BOV?

Mine is on the coldpipe because it wouldn't fit anywhere on the hotpipe. Personally I'd rather have my BOV on the hotpipe so it vents hot air and not cool air that has already been through the IC core. Also, any location on the hotpipe is likely plenty far from the MAF. For example, my old BPV was on the hotpipe but I have not noticed any real difference since switching to a BOV on the coldpipe.

you know your s***. I have a WeaponR pipe kit, i dont like the cold pipe too much there are lots of bends on it. I also have the TurboXS-RFL BOV welded on there already. i think im going to sell the pipe and the BOV and get a new coldpipe, something straight. And i think i want the HKS BOV.

Thanks - I've been here a while and I've done a lot to the car so I've definitely come a long way since I first joined back in 9/05. I will tell you right now the TurboXS BOVs suck - you will not be able to get them to work correctly with a relocated MAF. I've had two (Type H and Type H-RFL) and they both leaked around the piston (pressure test the valve, I dare you). Because the BOV was in front of the MAF and its vacuum source on the brake booster line it would draw in air from the BOV and place it into the intake manifold causing a stumbling idle and ultimately a Bank 1 - System too Lean (P0171) code. Both BOVs I had, I tested and neither would hold more than 10 mm Hg in vacuum. I've since switched to the HKS Super SQV (Special Edition Black) and I have no problem. Sounds awesome too.

As for the pipe, ideally you want as few bends as possible but you also want to make sure the final bend at the TB isn't too severe. Some of the higher HP guys have torched the #4 piston because of the sharp turn at the TB starves that piston of air.

"I'm glad you think you know what's good for everyone here though "

Im just going to throw this out here, you start s*** with EVERYONE. Why cant you just leave things alone. I was just throwing out an idea. Hell, I remeber this one thread where your argument goes on for like 2 pages. Your condescending and sarcastic remarks are very "buzzkill-ish", so to speak.

Sorry for the reality check.

I'm curious as to what this "one thread" is considering you've only been a member for three months.

When you have more experience with these cars then you can start throwing out your opinion.

turbo-xs can suck my dick. Had the type h on gives me the handy dandy lean at idle code. Switch to a hks and the code clears it self. Sealing bov>non sealing bov.

LOL and I told you this before you even had the car running!

lol but you know me i had to find out for my self haha
