Compressor Surge Anyone? (Vid) - Page 3 - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

sblack13 · 03-03-2008, 10:19 PM

Shit, people are scared to run no blow off valves. I swear, my friend sold his car and it had no blow off valve. Kid who bought the car thought the turbo would blow up. So he went and spent $100 on a hotpipe $250 for a hks blow off valve and $100 for a turbo timer. All to protect his T25.

Same kid who I bought his sr hatch back for like $2000
because he thought it was blown up
when he really ran outta gas.

lol funny:P

Pink Slut · 03-04-2008, 08:15 AM

lol my airfilter less ca18det sounds the same

. No BOV on that one aswell

SoSideways · 03-04-2008, 08:34 AM

I know the Enjuku guys were running no BOV on their red cars for like 2 years, doing about 20psi on the GT2871R .63 (T3 housings). That turbo was fine after they took it off for inspection a year or so ago I think it was.

punxva · 03-04-2008, 08:43 AM

yeah my friend who is in good with the enjuku guys asked Ken what they had been running and they didnt run any for the first 2 seasons now they are running them, he didnt explain why they changed their mind

corriganjoshua · 03-04-2008, 08:54 AM

some turbos may last a while but i dont see how a turbo hauling a** the other direction is a good thing haha

smelly240 · 03-04-2008, 09:04 AM

the turbo doesnt spin backwards...

That's right.

It is physically impossible for the turbo wheels, since the compressor and turbine wheels are attached to a shaft together, to change directions completely in a matter of milliseconds.

I guess it could happen, but it will take a lot more force than whatever boost you're running, and close the throttle quick enough to do that. Even then, I think something will break before spinning the other way. There's just too much velocity in the wheels....

corriganjoshua · 03-04-2008, 09:35 AM

just making sure that it isnt getting out there that this is ok becuase its not haha

smelly240 · 03-04-2008, 09:43 AM

except its not nearly as bad as pushing a small turbo past its limits (like most people do) - running 20 psi on a t28 for example.

but there are those people who do it and say theyve been running like that forever so everyone else jumps on the bandwagon and does it as well...just like this compressor surge fans haha

SoSideways · 03-04-2008, 10:17 AM

People that "run 20psi" on a T28, how often do you think they're hitting 20psi?

If you do that for a 1/4 mile drag, sure, fine, whatever, probably won't blow it up, but that turbo's lifespan will be shortened, guaranteed.

If you do that for a duration of a full 20 min hot lapping session for road racing, it might blow up after a couple of months if you race every week.

If you run that same turbo on like 14psi, but run no BOV, it'll last longer than a couple of months.

That's the difference.

Why does anyone do anything?

Everyone who does this is considered to be on the bandwagon eh? Well then fuck it, i'm on the bandwagon and I"m loving every single sensual second of it.

Um, if I really wanted to do the above, who are you to tell me not to do it? It's my car, my turbo, my money?

PS - way to go trying to neg rep me corriganjoshua. Either you're retarded and don't know how to neg rep, or your neg rep did nothing to me because you have so many red squares, but nonetheless, thanks for the neutral rep.

corriganjoshua · 03-04-2008, 10:30 AM

my apology i didnt know it was you doing this stupid stuff I thoght it was more of a universal conversation but if you want to ruin stuff all the time go for it more power to you...and as for the rep power not sure what your talking about and regardless of the color of some square that you can have givin to you for anything at all...it really means nothing to me and my opinions on how to build a good car are going to remain the same...some just want to be more efficient with there setups than others we all have our own opinions but dont think because you sit on this forum all day long and post all the time your the king of the crop regardless of red dots lol

SoSideways · 03-04-2008, 10:43 AM

Here's a break down for you corriganjoshua:

1) You tried to neg rep me. Didn't work.
2) If you knew how to read, you would have read that I am currently running a BOV even on my stock T25, but I plan on compressor surging it just before I put my new turbo on.
3) Maybe you could read, but you lack the ability to comprehend. Might want to get that checked out by your local 3rd grade teacher.
4) Not everyone in this world have to build their cars to your spec for you to approve.
5) Have you even driven a car with no BOV to experience the kind of response you have? I have, and I like it. Not at the expense of ruining a $1200 turbo, but for a stock T25, I don't give a shit.

corriganjoshua · 03-04-2008, 10:50 AM

since number 1,3 and 4 was just trash talk coming from you im not going to even waste my time...no i havent rode in a car without a bov i guess ill have to sometime sounds amazing...nobody cares what you do to your car its just letting everyone else including noobs out there know that it can be done better and safer...ruin good stuff than but dont come on these forums acting like its cool and influencing newcomers to do this stupid stuff...you sure are protective of your re points what are you doing to get all these good ones?

SoSideways · 03-04-2008, 10:57 AM

Your posts add nothing to this thread.

Please stop posting.

And since currently I'm not adding anything to this thread either, I'm going to stop responding to your vexing posts.

corriganjoshua · 03-04-2008, 10:59 AM

smartest thing youve said good idea should see if a mod can delete this bs

tougeracer · 03-04-2008, 11:04 AM

so back on topic, compressor surge sounds cool. Nice video clip, great job mounting the camera

Thanks man, glad you enjoyed it!

steve shadows · 03-04-2008, 11:30 AM

I figured because this is zilvia the last 2 pages were just non-sense so I am not going to scour the whole thread for this answer

Do you have a blow off valve???

how is it adjusted.

buy this

Best BOV

works everytime

It had the stock nissan bypass but I removed it and capped off the pipes.

steve shadows · 03-04-2008, 11:58 AM

Ok...then there you go.

Install a good BOV on the Cold Pipe and adjust accordingly

why would you do that? Small turbo without Surge Protected housing.

whats the point of this post? Bragging about breaking shit

I will do that. Thanks for your advice.

Quail · 03-04-2008, 12:59 PM

I get compressor surge with my BOV - its got a tight spring, so surges at low boost, and dumps at high boost. Sounds cool I guess.

Most of the UK SX guys run no DV with no problems whatsoever (on standard turbo)

Heres a vid I made to demonstrate to someone what Compressor Surge was:

I think he just made this thread to show what compressor surge is. He is well aware of it being due to no bov.

Mmm. That PWR bov looks interesting.

Glad you finally found mine. Your video inspired me to make a compressor surge vid from the outside of the car. Yours sound a lot better and a lot more pigeony than mine... and of course your car is a lot nice than mine.
