I've been searching through old post about the o2 induction manfold. i'm gettin the incon GTBB30/37. any ideas on how much extra power i could get with the st 2 manifold? would it work well with this setup?

At 12 lbs Rob Willams made a peak of 50whp with the stage 2.
See dyno charts at www.O2Induction.com

If a real person would post some dyno numbers with some more info on the runs then they would prbably sell more of them. I just want to know more about the performance gain. And the info on the sight doesnt do much for me.

how much do they want for those things? I heard it's some outrageous price..

if anybody is interested i've got a stage 2 prototype that's for sale. It's got a smaller plenum and longer runners compared to the production stage 2 but it also has tapered runners and internal velocity stack. Email me privately if interested.

The dyno numbers shown on the site are real.

The only question which nobody else has raised is why do these manifolds reduce HP and TQ at lower RPM's. If you ran your car above 5k-6k rpm's all the time these would be great. The dyno charts clearly show this.

This manifold was made for the intention of creating more top end horsepower. Yes, you do lose some bottom end. It should be expected. You have to lose something in order to gain something. The powerband aids a car with a relatively high rev limit (7500-8000rpm). Clearly everyone who purchased the manifold knew that. Most of the manifolds have been made for hot street cars and drag cars.

The reason you lose bottom end is simple. When you shorten the runner length, you move the power curve higher in the rpm range. When you lengthen it, you do the exact inverse. The prototype manifold that Turbo B13 works well, but many hours went into the design of the latest version which I feel is the best for both street and strip. The Stage III is for strip only.

The dyno chart is very real. Why would I waste my money, time and effort into creating false propoganda? If you don't believe me, I have the real dyno charts, speed data charts, and the spread sheet chart clearly showing the real numbers.

What more info do you possibly need to believe me? I posted the revelant info. The HKS EVC IV was set at 15psi (1.05 bar), not at 12psi.

I guess that's why Mike Kojima, Rob Cadle, Andreas Miko, Tony Q and many, many others have purchased the manifold from this "unreal" source ;) !

Any idea what it would cost to fab up a manifold for a VE? Seems like a great application to me. . .

The VE is a lowport design. After some test fitting along with some other design issues, it should be available soon. As a matter of fact, JD and I are going to the dyno for some baseline numbers before the installation of the Stage II manifold. We'll be sure to post these numbers from someone "real"!

I emailed you last night about one.. please respond..

By no means was I calling your data false or not true. I want to purchase one of these manifolds in the future but cant find anyone that has tested one on there own that has posted there numbers. That’s all I had to argue against. The manifolds look very nice and I’m sure allot of work goes into designing and making one. $800 is a bargain for any hand made intake manifold. Remember people we drive Nissans not Hondas. There are not 100 headers and 40 intakes available. You are the only person out there with such a product available and I have been waiting for any info I could find. Last time your product was brought up I asked the same questions and checked the sight every week to see if the info on the runs had been modified with the specs on the car that this was dynod on like someone told me it would be. No hard feelings, maybe what I said came across the wrong way.

A 50hp gain at 15lbs is awesome. What do you have done to your car? I made 305hp at 15lbs with an f-max stage 2 kit with an .82a/r turbine, s3 cams, ur pulleys and 3 inch exhaust. If I could make 350hp with adding the manifold or even 340hp I would be thrilled!!

hey.. what does your car spool up at? I have S4's.. and 9.0:1 compression.. Just wondering what's up with the .82 A/R housing..
Travis

I build full boost around 5000rpm. Its a little bit up there but pulls real strong to redline

Big Boosts manifolds are great. These manifolds are lighter than the stock ones they replace. They create more top end hp. If you have a T3 turbo or larger on your car this is the investment that will give you the most HP per dollar.

Look at the manifold like this, when you race a car you shift between 5,500 - 8,000 RPMS. So if you are building the ultimate high HP machine to go racing, then who cares if you lose 10-15 hp on the bottom, you will problably double that maybe even triple that up top. The end results justify the means in this situation.

02 induction by BIGBOOST has my stamp of approval.

"ITS THE SHIT" ANDREAS MIKO

I'LL DRINK TO THAT!!!!!!
:D :D :D

i don't think anyone will argue now, the man has spoken. :cool:

Thanks for backing me up Dre!!

Tomorrow Jackson Diamond (Russ), and I are going to the dyno for some base line dyno figures for the low port design. We'll post the info tomorrow evening!

As far as my car goes, it's going back together at the end of this month. When it's done, the website will be updated with the high boost dyno numbers finally. After it's done, I've got an arsenal of equipment that will be installed. I think the car will be absolutely sick to ride in. We shall see........

Rob

ok.. I've been looking at getting Turbo B13's manifold. A few questions..
How much difference will the longer runners and smaller plenum make? Less TQ loss I assume..? Also.. I was wondering if it would be possible to hit 400whp with the following mods and the stage II intake manifold.

T3/T04E (60 trim/60 A/R, Stage III/.63 A/R housing)
Fmax knock off manifold
HKS cams(similar to S4's)
9.0:1 compression Wisecos
JWT 50lb 4 bar/S4 program
JUN ultralight flywheel
UR crank and water pump pulleys
3" downpipe/exhaust
11.5lb 15" rims

Thanks..
Travis

absolutely possible....

Rob,

any luck with dyno-ing a NA car??? Judging from old threads there is a sizeable market for NA O2 manifolds. I know at least 3 persons that would jump at it if a dyno was available.
