**********'s New Intake Manifold 101

[CasopoliS]

Yea dynos on the same graph would be nice, but oh well. People know Street-Units number.... just call...

 

[azian6er]

Can you overlay the dynos so they can actually be compared at every rpm that you measured? Could you at least post them both using the same scale?

Why did you start the dyno at 4400 rpm's? It's not much above that that the VICS would be open anyway so how are we supposed to look at that and say that removing VICS would be better? When I talk about losing low end power/torque I'm talking about area before the turbo is producing peak boost, before 4000 rpm.

doesnt matter for me lol i dont make any power till after 4 k any ways

but hell Brian, last thing you need is more parts, what you need is a few more PSI... haha

3 more psi and you'd scream... but you need better tuning first.

I would also like to see this dynoed on a N/A car.

ye, but with this i might make 300 whp at 13 psi

I just checked it out,nice,but why did he go with such long runners?
who is this made by?
what kind of add on price is it for the extrude honing?

It is outsourced by a Japanese Manufacturer. We can send them out to be EH'd or you guys can do it. P&P can be done here too. Price is not set yet.

It's VTCS, not VCTS. I could tell it gets rid of that by the pictures, but does it also get rid of VICS (question)? If so, what would you reconnect to stop from getting a CEL (question 2)? Is there a drop in low-end torque, which is what the VICS is designed to prevent (question 3)? /end questions\.

Thanks Sean, fixed it. You can leave the sensors connected to the plugs yet unplugged from the vacuum source and there is no CEL. Before 4700 RPMs and after 5100 RPMs there were 9-12% gains above base line. In between 4700 and 5100 RPMs, the manifold did not lose power but gained 1-3% (3-5 whp/tq).

Hope this helps.

Price for the units, or price for the PnP?
Could you elaborate on the design and R&D that went into this mani? Was it based off another mani? Thanks Cullen.

Remember...********** is NOT an AV at this time...if they wish to conduct any sort of business (take orders, run GB's etc) on Mazda Forums they must have Authorized Vendor status FIRST! Thanks...carry on

SU's dues are paid, just not updated.

 

[CasopoliS]

can someone explain to the N00b what honing does? Thanks.

 

[StreetUnit]

The dyno graph looks kinda rocky, but I'll give that to the hot temperatures during the run. I'm gonna wait until some of these questions are adressed, such as where these came from, if Cullen is manufacturing them or something else. It seems like there would be a significant drop in torque in an NA car, so seeing a dyno from an NA car would be nice too.

I hope it's as good as it seems to be, but I guess we'll see.

There was a bad RPM signal lead which caused the rigidity of the TEST run. We will have a NA dyno'd shortly...

stop making ******* threads about this.

Watch your mouth. This isn't your private message board.

 

[CasopoliS]

thanks for the answers and being up front Cullen

 

[StreetUnit]

Ok it says that the vacuum lines need to be rerouted, what does this mean you need to replace with longer lines or replace them on a different place on the man.? And the throttle is that in the stock location for my intercooler piping, in other words will I have to replace my intercooler piping because the throttle is in a different place? And with the mods I have how will this benefit me? Tell me all you have to make me buy.

Piece of cake, I have a diagram here that will walk you through it. TB is in stock location, you can use your current piping. If you don't like it, I won't believe you.(wink)

 

[goku4658]

Nice to see you takin care of business, cullen!
I am also in need of an explanation of honing...clearly i'm a noob.

 

[goku4658]

also has the $50 coupon been permanently removed?

 

[StreetUnit]

It appears that the smoothing was turned off on the "test" run. there also apear to be breaks in the graph (usually attributed to not picking up the rpm's perfectly on the dyno sensor) and if you turn smoothing on the graph will go to s***.

one of my dyno runs from way back in March was just like this, and with smoothing turned on it look crazy.

but thats just my guess.

personally I'd really like to the the winpep files or atleast a .jpg of the two runs overlayed so I can really visualize the gains/losses at each rpm, etc.

You guys wanted numbers, I got you guys numbers.
Then you guys wanted proof.
You guys asked for Dyno charts, dyno charts were posted.
Now there is a problem with the charts.
The rigidity was caused by a faulty RPM signal lead.

I my personal opinion, you haven't said anything positive about SU since I can remember, so you, in my eyes, on the forum are a hater. But if you were to ever call asking for assistance, you would get the same respect and help that we offer everyone of you guys. So with that said, maybe you will refain from bashing SU and keep it to yourself.

Watch your mouth. This isn't your private message board.

relax cullen, there are like 20 threads about this same topic. (poke)

if you want to do some n/a dyno'ing, let me know, I might have some free time coming up.

 

[StreetUnit]

whats up? they took off the 50 dollar coupon too?

what gives?

Call and we will give it to you over the phone. No love lost.

Attribute for the EGR has a yes and no option now.
