New SBR Intake Manifold....How well does it perform?

[BOOstGhost]

http://www.slowboyracing.com/more.php?id=6001&
I was wondering if anyone is running one of these yet and how do they like it? Also how does it stack up compared to Venom or Magnus. Any bad experiences with them. Please don't turn this thread into a bash on Slow Boy Racing. Thanks for any input related to the topic.

They're relatively new so I don't think a lot of people have them yet. The design doesn't look too bad, the price seems about avereage. You can't get it flanged for a larger TB yet, that seems to be the only disadvantage.

agreed

the next smim I go with will be fitted for a q45 throttle body, if not, something even larger.

We have a larger plenum version coming that will only be flanged for the larger Tbody. This is why we choose to stick with the stock Tbody on this particular intake.

Hopefully this helps clarify!

Sweet, any idea on when you will be releasing that manifold?

Shortly after the first of the year.

Pricing should remain the same at $599.00.

Any dyno numbers or hard data on this piece? I'd like to see it stacked up to a Forrester, JM Fab, and/or Magnus piece if possible, maybe another shootout is in order here

Dang, I was just looking for this thread so I could post that. I would like to see how the SBR manifold stacks up as well.

do you normally have to have some sort of tuning instrumentation for smim or are they something where you can just bolt on and go? If you do need tuning for smims do you need link, or can safc/ or keydiver chips work?

To optimize performance you would want to adjust your fuel since you are now getting more air.

If you're still on stock fuel system, you have no need for a smim yet, power gain will be minimal at best. SMIM should come somewhere between cams and a built motor, well after turbo, fuel and intake system upgrades.

 

[KeltonDSMer]

Depnding on how the air is metered, not much adjustment may be necessary. With a MAS, it will regognize the increase in airflow and the ECU will automatically add more fuel. With a speed density set up, so much more is being flowed at any given boost/RPM and would definately require a new tune.

This is why I like MAS set ups, not much tuning is required when you increase volumetric efficiency because it recognized the extra in airflow.

i haven't run this manifold yet but i did get to see it. I was pretty impressed at the over all quality and design.

does it have the velocity stack

 

[SBR Chris]

does it have the velocity stack

No, we do not have velocity stacks in our manifolds yet.

Is anyone running this piece yet, any numbers or comparisons?

 

[Spyder FX]

Any pics of this larger manifold for a q45 throttle body yet?

 

[GstRacer]

not trying to jack the tread but how big is a Q45 throttle body?? how many MM i have a 62mm right now.

 

[slipstream808]

90mm... it's a bigun'!

 

[definitiveno]

Doesn't make sense to run a TB any bigger than your intercooler pipes does it? Seems like it's just adding more step downs for turbulant flow.

 

[Slow99x]

No. It works like a reverse velocity stack. Large throttle bodies also seem to improve boost response. Idealy you should have similar pipe size to the throttle body due to the better flow but it is not a must.

 

[definitiveno]

No. It works like a reverse velocity stack.

Reverse velocity stack huh?

 

[Slow99x]

Well think about it. A velocity stack takes air from a large area and moves it smoothly into a smaller space. Going from a smaller space into a larger one is the inverse of that idea.

 

[Elvenhome21]

Well think about it. A velocity stack takes air from a large area and moves it smoothly into a smaller space. Going from a smaller space into a larger one is the inverse of that idea.

Not exactly, the purpose of a velocity stack is to speed up airflow, by going with a larger throttle body then the intercooler pipe is just a pressure drop point, but being under boost it doesn't affect it as much as if it was N/A but normally after the first coupler out of the turbo that is what all of the piping should be all the way to the tb including the tb.

Pressure drop is generally bad which is why this intake is tapered to equalize pressure between all 4 cylinders

If the Magnus manifold is so good, why is it the only manifold to feature this taper? Why do other SMIM make more power as well (AMS VSR)? I think that if it was that important then other engineers would have designed the manifolds just like that including Mitsubishi.
