SBR Cast Manifold

[green92gsx]

There is no easy way to answer this question, but I will throw my reasoning in here.... because people pay to have it ported. Is that a good enough answer, or did you want me to fluff it up?

We have 5 to 1 request for T4 over T3.

I guess that is a good enough answer for me. You don't have to surgercoat anything for me Mike,I didn't order it from ya'.
Just curious since there is custom casted turbine housings.ie,Bullseye,Fp,and Pte. That advertise smooth castings that don't require porting. I figured a cast manifold could be made the same.

There are many different type of castings... and many different casting companies. OUr old manifold, was a bit rough inside, and erally did benefit by having some sand rolls down through it... our new manifold however, even without shining up the runners, is very smooth for a sand cast.

Investment cast, like FP's turbine housing are very nice, but not practical cost wise for a manifold that needs to be priced under $300.00.

PTE, Bullseye, and our turbine housings are all sand cast and very similar.

so what kind of power can I expect a ported SBR will give ya over a stock non-ported manifold even if I stay with a 14b?

I wanna know,
Josh

52.23464 whp.

to put that into perspective, would you ask how much horsepower a new o2 housing would give you? or how many more g's you can pull with a new swaybar?

**ok, I felt like a jerk for saying that. I like to consider getting a new manifold or porting your existing one as a supporting mod. Basically, you're just increasing exhaust flow. the bigger your manifold/turbine/o2 (of course TOO big is bad also), the better the flow and the better the spoolup time for your turbo. Also, porting is indeed necessary to rid of boost creep.

IMO, since you have a 94, go ahead and get a 2g manifold/o2 and port everything out including your turbine housing. you will see a great "placebo" gain from that. If anything, you will notice better spoolup and a difference in power. I guess the question is how much power (but a dyno will only tell you that).

Actually I would ask how much a o2 housing would give me. I mean, I dont see why its a dumb question. But don't exhaust companies tell you how much power they gain when they advertise their products?

And if just manifolds increase flow(which in turn can make more power, not just spool up time) and thats it then why do the Honda people go with componies like Full-Race instead of going with a cheapass manifold? Maybe because they make more power?

Im not looking for it will make you 12.34832 power, Im just wondering about what kind of gains be expected. Just an estimate, or some gains other people have dynoed with this new manifold.

Not to be a jerk but Im just looking for actual answers that answer my questions.

anyone know?,

You should pick up a few ft/lbs of tq... however I would suggest with a 14b not any additional WHP at the same boost level.

MGH

It's not a dumb question. It's just a very vague question that you will never get a true answer for. and upon more research (when you do), you will notice that most of your "how much horsepower" gain questions have been answered a dozen times over.

but.. as stated above, SBR has cleared that up for you

 

[Catbox_95]

So many times I see people on here asking how much horsepower something will give them. The real world is not like Grand Turismo 4, where you just buy parts that give you x amount of power, etc.

In other words, there are no real answers to these questions. A ported SBR manifold may make someone's car feel faster but not be, someone's car be faster but not feel like it, someone's car gain a few horsepower, someone's car lose a few horsepower, someone's car be slower, etc. With the millions of tiny variables that come into play with each individual engine, the possibilities are absolutely endless. A + B does not always = C.

You get the point. You'd be better off just asking people who have one if they like it or not.

I understand where you are coming from on this. I was just wondering if there was just a ball park of what kind of power you would gain with this. Given a certain setup. But I totaly agree that it is hard to say in real world Gran Turismo 4 since there are soooooo many variables.

So has anyone tested this new manifold vs. others?

off to bed,
Josh

 

[daren_p]

I noticed a HUGE power increase when I installed my SBR manifold, I gained 8lb/min (~80 hp). Oh I forgot to mention I also added an evoIII to replace the t25 while I was in there .

SBR's new cast manifold does look great. I have SBR's 1'st cast manifold, and I now wish I had waited and got this manifold, although who knew that there was going to be another manifold?
The only reason I wish I had this manifold is for its ex. WG, B/C this winter I am switching to the Tial 38mm, but I guess I just have to buy the flanges and have it welded on, which is not a problem.
My guess would be that the internal dimensions or both SBR manifolds are the same and the only difference is the new the new ex. WG flange and a tad bit difference in the casting materials to help w/ cracking and warping.

You are correct, the collector area is a little different, and the wall thickness is .060" thicker. It is also cast here in Pa.

im also in pa as you can tell and the new sb cast manny is the #1 best bang for the buck i mean i like headers in a way but to me there just too expensive due to the fact we all have bills...so when i got this manny (primary reason b/c 1g manifold cracked with 18 psi) bolted it on and turned boost up from 12 back to 18 i felt a nice gain and this with stock exhaust cept for manny and and my intake is where i want it...next step port 14b both on the exhaust side & where the compressor outlet pipe goes ( thx to dejonpowerhouse.com cop-a) then evo 02 ported, rre dp, and apexi, just 1 part at a time...

 

[funguy]

Our new manifold, the $50.00 port job is porting the entire manifold.

Thanks for considering the manifold, its a great piece!

MGH

i just bought this manifold and recieved this week through your sister company up here in canada. To say the least, i asked for it ported and it looks like this thing you guys spent 10 minutes on. Not to bash you guys, but definately if you guys say this thing is fully ported for the money please mean it, the piece ain't near that of the pictures in page 1 or your ads. the runners looked to be only lightly sanded 1.5inch max down the runners. collector area flange has burrs all over it. it already took long enough to recieve this piece so i ain't going to send it back to you guys. Couple big casting pit marks on the top of #4 runner @ least .050deep. i'll just do the rest myself

 

[brrrnntsshhhh]

my friend got one of these like 6 months ago, it cracked already.

 

[SBstar]

I know I'm in this thread somewhere in the beginning, but I would like to report that mine is holding up great, the porting looked decent, and I would definately recommend it for those who don't want to go tubular. The porting could be more extreme but overall its well done and I have zero complaints with this manifold. By the way I've had it since they brought these newest ones out.

Have him please get ahold of one of us!


And thanks for the compliments guys!

This happened to the SBR manifold on one of my buddy's cars:

Wasn't on the car more than a few months. The turbo was a GT13, 38mm Tial gate.

It started out as a small crack, and the next thing you know....BANG.

I wouldn't put one on my lawnmower.

 

[blcknspo0ln]

Wow.

 

[ILLiCliPSE]

W-T-F. Wonder what SBR has to say about that. Chris...any insight?

 

[VTEC_THIS]

^^?? WTF - Doesn't look like a crack from poor product looks like someone took a hammer to it

I guess I am happy that mine got stolen. The poor b@stard that took the thing now has a ticking time bomb.

NO hammer. The crack started at the top of the collector by runner 2 and began to trace outward toward 1 and 3. Apparently it was also cracked on the bottom where it couldn't be seen.

It happened while my buddy was racing at Piitsburgh Raceway Park, the last pass of the night. Car pulled strong the whole way through the quarter, and when he backed off at the end of the run the car shut off immediately. He thought something happened to the engine. Once he got out of the way and lifted the hood, this is what he found.

Luckily he trailered the car to the track- it would've been a long drive back to MD otherwise.

 

[VTEC_THIS]

Jeeze, your friend should definitly call SBR. They should be able to help your friend out. Despite what a lot of people say on the forums Slowboy is a good shop and I've had nothing but good experience with their service and parts. I'm sure they'll replace it, or give him a credit towards something else

 

[Street Surgeon]

Damn, another SBR product that kicks butt!!! Or, no it sucks... Luckily you can rely on their always stellar customer service!
