I'm getting a flange welded to the pipe for a BOV and I need to find out if the pipe is steel or aluminum (so I know whether to get a steel or aluminum flange).

Also, anyone know where to get a flange that works with the Blitz Supersound BOV? It has a 2-inch diameter. The local tuner shop will look for one for me, but in case they want to charge a lot for it, I'd like to know where I can get one that's inexpensive.

Thanks,

Tanman

Btw, this is the BOV I have:

bullseye

Easy test...Got a refrigerator magnet?

If a magnet is attracted (sticks to it), the pipe is steel. If the magnet is not attracted to it, it's made out of aluminum.

I wasnt' aware that a flange was missing on the pipe to take a BOV.
Btw I've got the latest Blitz BOV on mine.

Tanman

Well, you mount it where the Bosch recirculation valve is mounted, but I don't think the mounting area will accept a BOV. I haven't removed the recirc valve to see what the mount looks like. Anyone have pictures?

I know that there is extra piping on the 5th gen SC, but anyways, here's a shot of my 4th gen engine:

Kevin welded the falnge onto where the recirculation vavle opening located. hope my sig will help.

Tanman

Yeah the 4th gen piping is different from the 5th gen. You can see in the image how the recirc valve is connected to the charge piping by that rubber sleeve. A BOV will not mount to that flange, the head is too small.

Tanman

Hey maxi, is the flange steel or aluminum? That's where most people weld the flange.

Actually, I think Kev bought it already mounted .

iTrader: (3)

oops...that I did not he bought it mounted.


btw, it is steel for mine.


btw-1, arent we suppose to save money for 5-gear?

Tanman

If you check the pics on his Cardomain website where he's taking the SC out of the box, it shows the BOV mounted on the charge piping .

Cool, I'm going to try the magnet test and make sure.

I bought the BOV 6 months ago but haven't had the time to get it installed. I kept reading the horror stories about how the car wouldn't run when the BOV was installed. Finally going to get it installed, just need the flange and $75 install cost.

I'm going to start saving for the tranny swap. I'm guessing I'll save enough within 1.5 years to afford it ($250\month for 18 months=$4500).

ah ha....some adam (my 4DSC) did it for him already....

are u reading IanW's story about BOV leak? where he gets inconsistent pressure through-out each gear? I wonder if he got it resolved.

want me to install it? I can zip-tie it for ya! j/k

about saving money....I will "try" to save 150 - 200 a month and pray to god everyday that my auto tranny will live for 5 years....then I will have my tranny swap fund ready by then. I grandma shift 1-2 and 2-3 these couple days....the tranny fluid is a bit cooler....and I'm only allowed to boost 2 times a day...wish me luck.

its plastic

I didn't see that thread, but I read the ones about the boost leaking. I think maxxboost00 had the same problem. Most people seem to be able to fix it by swapping vacuum lines to get a correct reading (that's what Y2KevSE says ).

5 years? That's a long time to keep your car, eh. Especially a boosted\modified car. I'll be happy to have my car running for a total of 5 years. In 5 years, my Maxima will be 7.5 years old, hopefully I'll be making big money by then and I'll be driving something like a GT-R .

2 boosts a day limit?? Not a bad idea, just impossible to live up to.

Tanman

Correction, it'll be 8.5 years old in 5 years. It's late .

Tanman

It's steel.

nymjayjay

its plastic I tell you

Tanman

How would you know? That image in your sig isn't even of your car .

I've tried 4 different gauges, thay all do it, from several different locations, including right off the manifold. It wasn't my gauge or vacuum line.

However, I spent today on the Dyno, and realized my BOV leaks boost at high RPMs. (5000+). Trying to find out if this is normal.

If figure, if that is the problem, the reason that my boost dropped more and more (8PSI 1st to 2nd, 6PSi 2nd to 3rd, 4PSI 3rd to 4th) is because I sit in the leak area longer (spend more time in high RPM's) and more leaks out.

Although I did a run today without the BOV being activated, and I got worse numbers, so who the hell knows?

yup....unlike 4th gen, our vb does not shift hard as theirs and sometimes the frist - second does not feel like VB-ed. The only SC that has a blown tranny with vb/cool is skimax's. but 5th genner, we have seen 2 so far.....scary.

so, before I boost...I think about those trannies first.

I read several of your threads about investigating the missing pressure...

so when u have the BOV off....do u see better pressure in all gears?



thx

nymjayjay

it sure as hell is my car, check out my homepage

I was kidding! forgivanuss, prease.

Edit: I just checked out your webpage, very nice!

you are forgiven I will let you live this time

It's titanium.

rusty titanium

Y2KevSE

iTrader: (13)

The powdercoating is what makes it so heavy. The rusty looking speckles are special high flow molecules produced by the titanium which enhances combustion which improves engine efficiency to about 99.9%.

Tanman

You're not the jovial type, so I can't tell if you're kidding or not. If it actually is titanium, do you get a steel or aluminum flange for the BOV?

the stock piping is steel.

if you have a greddy bov, you can bolt that right onto the stock piping. its the same size at the BOSCH blow off.

only if you want to attach say an HKS or Greddy bov do you need to reweld it.

Y2KevSE

I used an Uranium flange... steel worked great.

iansw

iTrader: (7)

So you do you have to weld the greddy or not? Above, you said you don't have to, then that you do.

IanS

Y2KevSE

iTrader: (13)

He meant Blitz (4th gen only)... you will need to weld the GReddy flange on.

Tanman

Wow, does it glow and emit harmful radiation? I'm guessing most people think it's an underhood neon kit.

Ok, so you have to weld a flange if you use an HKS or Blitz BOV.

ic...so the rusty speckles help my engine combust better. I am thinking about a more efficient method by mixing some of those titanium stuff (like 1 lb or so) with my engine oil along with some coolant (about 1.5 Liters) as a chemical oil cooler. To allow faster flow, I decided to remove my oil filter as well.....

u know.....if the uranium flange goes kaboom....we live pretty close.....probably LA people will see the mushroom cloud on TV.

Tanman

Wow, secret encoded messages. You Cali people live in your own world.

[maxi-overdose]

iTrader: (3)

that's why we are fast....and everyone here has mixed metal shavings with their engine oil to get maxium combustion rate and it took me years of R&D to determine right amount of shavings with right amount of engine oil and coolant.

wanna try? I can e-mail the secret to you with a discount....comes to 10.99 total and no tax for non-cali resident.

whoops

i meant BLITZ needs no welding

BlackCat

iTrader: (6)

Isn't this called a "dirty bomb"? Hate to be downwind from it.

Tanman

You might not have to weld a flange for the 4th gen piping for a Blitz BOV, but you definitely need to weld one for the 5th gen piping.
The inlet is about 1 inch in diameter, the BOV requires a 2-inch flange.

Tanman

Whoops, correction, looks like Kev cut off the old Blitz BOV and flange and mounted the Greddy BOV and flange that he sold to you. (It's tough to keep up with Kev's mods ).
