ok here is the problme i wanna run my sr unrecirculate

[redtop91]

Seeya.

[IanS]

When I first did my swap 3 years ago I ran no BOV, I didnt have the money for it so I did my research and capped off the fittings, guess what, running 7 PSI I went through 3 T25s in 2 years, after the first 2 I started rebuilding my own. Over a year ago I installed a recirced BOV after rebuilding my turbo for the 4th time, I havnt had an issue since, and Ive also stopped blowing off IC couplers. Your level of anger in this thread only proves your maturity level.

just have no BOV or recirulation value. have compression surge, it sounds way sick then a hks or greddy. COMPRESSION SURGE DOES NOT HURT YOUR TURBO. most of D1 drivers run there cars with no BOV, they all have compression surge

BOV=RICERcompression surge=real drifter

Aren't you contradicting yourself a little?

This whole thread is the most retarded thing I've ever read on Nico. Seriously.

[redtop91]

Minus your posts?

[otterman]

Exactly.

Guilty_coupe is one of my good friends and hes been around for a long time in the 240 world. what about five years now. in the sac area we have about 20 or so 240s with turbos and most have compress. surge, but were not dumb and over boost our motors so we dont blow turbos. i run a ca with about 1 bar of boost consistently everyday for about 2 years now and guess what i have COMPRESSOR SURGE. never blown a single turbo. actually one of my friends with a blitz blow off valve had his studs back out and thats never happened to us with compressor surge. so guys get your head out of your *** and stop being dumb and ignorant. hate me if you want but i do have some experience with this ****.

so putting a BOV on your car now makes the turbo fall oof?

MUST.....RESIST.....URGE.....TO FLAME!

my chest hurts from laughing so hard

[Stripes]

Yea, this whole thread is pointless. the guys question was answered, and there is no point in arguing on a forum. if guilty says he's been running uncirculated and it works for him, then i guess thats his own experience so you can't really say that he's a moron if that's how he runs. if you guys know different and think that his turbo is gonna blow, then hey thats cool too. but i myself don't know much about the pros and cons of compression surge, so im about to find out for myself. To Youtube!!

[Tulsa_S-13]

Ok, so I had typed a response regarding the physics behind the bypass valve, but then decided it was completely pointless since this dude probably wouldn't understand it

Oh yea and

[blinker_fluid]

This thread has been jacked like none other.......

Your mafs measures air which is accounted for by recirculating it. Get it tuned to run unrecirculated.

Everyone else...(turbo 101) a turbo uses friction from the compressed hot exhaust gases of an engine to spin one turbine, which in turn spins the intake turbine that compresses cold air and forces it into the engine.

(chemistry 101) hot air is not as dense as cold air.

(Common thinking) Cold side of turbo will make more friction than hot side...hense when you don't release the unused intake pressure compressor surge happens because cold air is denser than hot air. Its like the intake turbine hits a brick wall.

( ) I had to think about this damnit.

(epiphany/ question) Which of the two has more density: compressed atmosphere or hot exhaust gas (not hot air)?

[guilty_coupe13]

****a BOV. I guess all those d1 drivers are stupid like kazama, ken nomura, kuroi, etc....because they all run compression surge.

another reason i don't run a BOV is because for one they sound bag of rice squirting out of car (especially the HKS one) and to be different. and also compression surge is JDM.

if i could meet you all in person. i promise that my friends would make fun of you.i just told them about how stupid people are on forums and they all agree with me. that's why they don't even bother talking on forums because retards like all you who think you'll blow your turbo if you run no BOV. or when you put a different motor in a 240 instead of a SR.

[BuLLeTdrift]

IMO, no blow of valve, just back pressure/compression surge sounds a million times better than running a BOV. But You are the first person i've ever heard saying that not running a BOV will never harm your turbo. I understand why running one will help the turbo, but i cant see how NOT using one will still not harm the turbo. OH well, just installed my SSQV lol. Good thing i build my cars for myself and not for anyone else.

I dont even remember how this thread started.

I didn't say running a BOV is bad for your car, i'm just saying i rather have compression surge.and people think that i'm lying its making me hella irritated. i've had compression surge on my car for days and i haven't blown a turbo. and people think its impossible for my turbo to last that long with compression surge.

i guess everybody should listen to redtop91 because he has the most posts on NICO (13,000 posts are you serious? i wounder if he's ever got ***** before. he makes at least 30 posts a day! does even know how to wrench on a car.) which makes him Smoky Nagata of NICO. I'm just a fanboy because i don't listen to are leader redtop91. basicly if you have compression surge your turbo fins will be flying out of your exhaust and your motor will blow in which the piston shots out of your head of your motor. in fact, you'll probably die if you run compression surge.

i'm also glad that i build my car myself too and not let anyone else.

amen to that. I'll never let anyone else build my cars. uber mistake. btw, sr20 is not the best motor, LSx is IMHO that is. compressor surge also causes more lag when you get back on the throttle vs having a BOV and it will increase wear and tear on the turbo period. You may get away with it for a year, two, three, depending on how much and how hard you drive, but it does affect the life and operation of the turbo.

i agree that compress surge causes more lag when you get back on the throttle but a little turbo lag does not hurt. compress surge maybe not be the best setup for a drag car but for drifting, turbo lag won't kill you.

see i was just making a suggestin to run compress surge. that's the reason people come to forums, to get other people opinions. i don't care you don't have to listen to me, it just made me hella irritated that everyone thinks i'm a newbie and that i don't know **** about cars. and how everyone was like "if you run compress surge your turbo will explode."

just because someone has more posts then you does not mean they know more about cars then you do.

please please please read this thread,zerothread/209315 I just cant take it anymore, my brain hurts from trying to understand you.

[Eikon]

This has to be the dumbest thread I've seen on NICO in a long time.

What the hell is in the water in Sacramento?? That's apparently the void in the earth where the rules of physics don't apply? I mean, I knew California was special, but I didn't know it was this special.

Stop spewing crap about what your friends say and what you "think" you know about drifters. Start reading some real information that has scientific basis.

Compressor surge = The normal flow of air through the turbo compressor wheel is slowed and/or reversed, then accelerated back to normal. These repeating oscillation cycles cause uneven thrust loads on the bearings and if the oscillations hit a harmonic frequency of the compressor blades, they can cause blade damage.

Now to boil it down so you Sac-town people can understand.. Compressor surge = Bad

Get it?

Get a BOV (blow off valve) for two reasons. First to prevent compressor surge (which = BAD) and second to help reduce lag (less lag = faster car).

Do we really need to continue this conversation???

Any recent 21 year old Wyotec grads want to chime in? Any rb26 owners? Any friends from Sacramento have any more ideas on how physics are different in your part of the world than everywhere else?

[sr28]

i have the ssqv on my sr.. i just raised the idle to 900 and when i let off the accelerator it wont drop under 800 so you really wont notice it.. besides from the fuel smell and the flame depending on how hot your exhaust is

[S13FX]

Hey I get compression surge on my pistons every day, not only that Im about to start stroking my KA, cause she likes it that way.

As for an RB in a 240. All I did was put some fluffy pillows under the engine and walla no more heavy RB WOOOT.

Did I mention my pillows are JDM . So is my KA.

^^wow, that's awesome.

Guilty_coupe "All your compression surge are belong to us" "Some one set up us the real drifters"

Thank you!

Now, can some Mod please lock this thread. It's full of misinformation done by one party and hurts my brain to read.

Any thread that causes brain damage should be locked, eh?

[R6_240sx]

Done.
