Anyone with Blow thru maf setup..??

[GhostDrifter]

It doesn't look that way. That's the discussion here, they're trying the MAF out on the cold pipe and the BOV on the hot side. This looks interesting, i wanna see how this holds up.

Yeah that's what I wanna do cause when I blow off I want it to be right next to someones driver door.LOL. I think it looks better also

RN:Where in Orlando are you, Is it possible for me to view your set up?I am very concerned with idle issues. The reason I am deciding to turbo my car is because I needed a new engine due to a mysterious idle ailment. I figured if I need another motor, I might as well get some power out of it.Please email [email protected]

does the BOV have to be on the hot side with blow thru maf set up?

No it does not, but its a safe practice that everyone has been doing for yrs now. I have seen people do the blow thru setup and put the bov on the same cold pipe, but they always put the bov b4 the maf..

Im working tomorrow sat 3-18 so i wont be home or be able to meet with u during normal hours. I should be out saturday night if all goes well. I normally hang at the corner of orange and colonial if u wana swing by and check it out. Usually out there after 9pm..

Not on a sunday night... Who goes out on sunday night..??

[emperor_lunchbox]

when is the next day you will be out there?I am having problems keeping my car running so I will have to plan to be out there. Thanks.

when is the next day you will be out there?Thanks.

Im only out there on sat nights... But not every sat night, i do have a life outside of this car meet

[emperor_lunchbox]

thats cool. The next time you go, shoot me an email and I will go. I am a very long way even being concerned about MAFS placement. I still need to get the motor built and into my car. I made a post about Orlando Locals helping, I think you even replied, But I havent had much luck. Also, there arent any shops that will touch the KA motor. CFT and a few of the other will only work on "performance" engines.Anyway let me know when you go out there and I will pass by.

i run a blowthru setup on my rb20 s14, and it works a treat.whats nice about blowthru is that it can be used to stabilize a lopey idle that cams can cause in addition to venting the bov atmosphericly.only prolbmems ive had with it so far is the wires getting dirty (have to clean the maf every 2 months or so) and the plastic "square" on top of the maf (z32 maf) popping off, but its nothing a bit of silicone and some zipties didnt fix.

The machine shop work that was done to my block and head was done by PCC in kissimmee. Me and a buddy hand built my motor back together inch by inch.. What needs to be done to your motor..??

What pressure are u pushing that keeps popping that square off..??

I have only pushed it to about 12 psi if that and only for a second or two cause im still trying to get used to the turbo now sounding LOUDER cause i left the intake side open, no filter, no screen, just plain naked... So now when i go under boost, that suction sound is incredible and scare's me half the time... Its one of those things that im not used to that i have to grow to. Kinda like the 1st time i went open dump on the wastegate.... Talk about scary...

[emperor_lunchbox]

What needs to be done to your motor..??

Pretty much everything, Its sitting on my patio in pieces. I was thinking about buying a rebuilt block and head from Duron on KA-T.org.Its really too big of a project for me to have taken on by myself. I dont really have the tools or the experience.

How many pieces are u talking..?? Are we talking a FULL rebuild from BARE SCRATCH or 1/2 rebuild or what..??

[emperor_lunchbox]

well, the block, head and valve cover are still on, everything else is in baggies in my closet.

I havent really decided what route I am going with (Duron's engine vs. rebuild). His engine comes with a warranty though. I was thinking if I got one of those motors I could focus on gathering parts this way when the motor comes in I can install the new motor, the 5 speed and the turbo. Basically a totally different car. Once I get this stuff taken care of I have a few other problems. Brakes and old suspenstion mostly.

[Carl H]

my high boost was 18psi, and the car was driven daily at 14.doesnt take much to make the maf pop but once you reseal them they are mint, mainly just 10year old silicone not sticking anymore is the culprit.

[rn240sx]

I just got a reply from a freshalloy memeber that said he pushed 30 psi thu it a few times and it never popped on him. I dont plan on passing 23 psi ever. My turbo just isnt very efficient at that level..

[nismostate]

any updates on this subject?

Still got mine, it has seen 16 psi so far, no issue's. Pulls so much harder and throttle responce is impressive..!! Very happy with this setup..!

how long have you had this setup? about how far away is your maf from the tb and what size cold pipings? i plan on putting mine about 1.5 ft away. "estimate". will probably boost around 16-18 psi with s14 turbo and safc2 tune on stock sr. still interested in doing blow thru but don't want to replace the sensor anytime soon..

[rn240sx]

About 2 months now, keep in mind this is NOT a daily driver.. just a sat night street / drag racer ..

Quote »about how far away is your maf from the tb and what size cold pipings? [/quote]On our 240's there is an a/c condenser or whatever that round cylinder is called, but it sits between the radiator and motor right next to the lower radiator hose... well thats where my maf is at. I cut into my intercooler piping and slapped the maf there in-line.. The cold pipe is 2.5 inches

If i would have went the sr20 cold pipe route which takes the cold pipe up thru the battery tray, then that would have costed me much more money cause then i would have had to fabricate a new cold pipe from the intercooler to the throttle body..

I had pictures of the setup and i dont know WTF happened to them...

[david200095367]

it seems like many have no problems with a blow thru setup, but i tried the blow thru setup and it fried the maf in 3 minutes under 0 boost. So i dont know what to say. Oh and check out this link for kat parts.

[nismostate]

err.. well i think my plan is to go pull thru first. tune it then go blow thru. doing blow thru set up is pretty simple for me. i just have to cut the pipe shorter coming off of the ic on the cold side then clamp the maf in between. its not my daily driver but i drive it often and i drift it so i dont need it breaking on me at an event.

[rn240sx]

well, some people have had good luck even at high boost levels, some have had bad luck at low boost levels and high levels...So its pretty much a luck of the draw and ive been lucky so far (knocking on wood)...

[skillet]

over a month now, boosting 1 bar every day, and driving hard on weekends, no problems yet.

[egan]

which maf are you guys running blow through? or better yet, which maf would be best for blow through between s13, s14, and z32?

in my situation i would be running 6 psi so s13 maf is still an option. i just wonder which would be best design to meter the pressurized air.

[rn240sx]

Here are the pics of my blow thru.. finally found them. They were saved in a folder that i never go into.. How the F*ck they got there beats me, anyhow here they are..

[Carl H]

if you run blowthru you'll have to clean your maf every couple of months or so to remove the oil residue that can accumulate...electrical contact cleaner works VERY well.

[drEameRvaJ]

I'm looking at a intercooler kit for my car.The guy is running a blowthru maf setup.This is how his setup is.The TB to the MAF, MAF to the BOV to IC.They are all on the coldpipe.How do you all think this setup will work?I'm not sure how a blowthru maf setup is different from a regular.Anyone can help explain?I would appreciate it.Thanks!

[iam_so_slow]

hmm... what maf are you guys using? im thinking about using my stock s13 sr maf...kinda because i dont have money to afford a z32 right now... my IC is 2.5 outlet to a 3inch pipe to the TB im thinking about placing my stock MAF right after the IC...do you guys think ill run into any problems?
