it seems like since they moved they pretty much fell off the face of the planet. does anyone have their header? Ive been waiting for numbers/reviews. their header looks like it would free up more down low torque than any others on the market and Im looking forward to seeing how it performs.

 

bump

 

Maybe they're gone because their product didn't work. They made a big deal about their header being a "true" Try-Y, when, in fact, it was built incorrectly and didn't even have equal length primary tubing. I posted the following to their introductory thread and received no response:

"Looks nice, but is there any science behind it? For one thing, it does not look like the tubes are equal length. Second, your comment about other headers being configured wrong...Going back to the '60's, at least, from companies like Alfa Romeo, tri-y headers for a 4-cylinder configure cylinders 1 and 4 to one Y, and 2 and 3 to the other, based on the 1-3-4-2 firing order. At low speed, the second Y acts as the scavenge when adjacent (in the firing order) power pulses scavenge each other. At higher speeds. when the pulses are closer together, the first pair of Y's scavenge cylinders that fire 2 apart.

So, what's the science behind your set-up, which goes against a hundred years of convention?"

I would stay far away from it - their design will most likely make less power than a 4 into 1. I find it hard to believe ALL the major car companies over the years have been wrong, and these guys got it right, especially when, from an engineering standpoint, it doesn't make any sense.

We are still here.
We have been concentrating on getting caught up on back orders due to our move.
We are going to be testing the firing order in our Solstice/Sky Tri-y Header to see what actually works best, due to so many who have asked what would be best.
With our test it will be ideal since both are of the exact same design except for the firing order. Once we are done will make any changes that are required if any.
Here are some pic's of the two different headers. These are for the Solstice/Sky, NOT for the Cobalt

 

Not bad looking headers you got there. They would look good if they were cermic coated.

 

Yeah they look great! Too bad they're for the wrong car.

Hey I know lets all ask Hooker for their latest Big Block chevy headers, or for their newest design in NASCAR headers since it'll do us as much good.

Making a good looking is header is great but making one thats for our car is better.

 

I only posted the Solstice/Sky headers to show what we are going to be testing for the correct firing order. The end results will be applied to our Cobalt header when we are finished, if needed
And yes we do have our headers ceramic coated, by request, these were just finished when the pic's were taking.

 

well ill be waiting lol.

 

I know I was being sarcastic.

I did say it was a nice looking piece.

 

Jackalope? Sarcastic? NEVER!!!

 

No worries

 

could you post the results of that test on this forum? good to see companies testing and making changes if necessary

 

Yes we will, as this all pertains to a Tri-y design and it's firing order for this Ecotec motor.

 

 

Actually, it applies to the firing order of every modern in-line 4-cylinder. They're all 1-3-4-2. It has to do with balance. Evan at that, an in-line 4 with this firing order has a harmonic at twice crankshaft speed in the opposite direction, which gives them all that characteristic 4-cylinder "buzz" and is the reason behind internal balance-shafts (timed and weighted to counter this inherent harmonic). Different engine lay-outs and firing orders have different harmonics. See http://en.wikipedia.org/wiki/Engine_balance

 

We are getting closer to getting this test done. My partners Solstice has developed the common issues that have come up with this car( rear end differential ) and he needs to take it in for warranty work at the dealership first. We don't' need to be blowing up a rear end on the dyno!
What we do know so far as to the performance of our header and another with a different firing order is that with a supercharger that is being offered for the Sol/Sky, running the different headers, is that ours is performing better (two individuals that both have Dashhawks on their cars and doing the same test.)
Also because of the very different design ( and this is why we are conducting our own test with our header designs ) between ours and the other header, there is a very different noise coming out of each header. Ours is described as a very good performance sound, as the other is described as just the opposite, and was immediately pulled and exchanged for ours by the owners request.
After hearing some of these results so far, we are even more curious now, so, as soon as we can get to the dyno and get the test done we will post the results.

 

X2,, why instead of giving us your results on the soltice/sky header, you do it with the cobalt header?

 

We are using the Sol/Sky header because it will be a true back-back comparison of the two firing orders.
Since they share the same motor, it will be information we can use for the Cobalt header
With the current Cobalt header design we would not have this opportunity. Another firing order design for the Cobalt would not have been as close to one another as the Sol/Sky headers.
I hope that answers your question

 

I know what your trying to say but...
why instead of comparing the sol/sky motor with ours you use directly ours? then there will not be any missing link on translation...

 

I can see how it would sound different - we saw that same effect on small block Fords with tri-y headers versus 4-into-one drag headers in the '60's. Generally, the 4-into-1 headers gave better all-out performance at the expense of low and mid-range torque, making them much better for drag racing, and the tri-y much better for road racing where performance across the entire rev band is necessary.

What I'm curious to see is whether you will see more area under the torque curve with the 1-3-4-2, or even fire header, than with the 1-2-3-4 header (which will act, from a scavenging standpoint, more like a 4-into-1, as the scavenging from adjacent firings in the firing order is lost - basically you have a pair of pulses in the primary y followed by a pair of "rests" or no pulse). Can't wait to see the results!

 

Well, I have my car scheduled in at the dealers tomorrow to hopefully take care of some problems I have been ahving. If all goes well we will schedule dyno time next week and try to get all the testing out of the way.

Beth made a post earlier today and it was removed. Apparently my user name isn't associated with our vendor status. The admin are looking into it now.

Until they figure out what's going on we will refrain from talking about our products.

Thanks for everyones patience. We know many of you have been waiting to see some numbers and more importantly, the difference between the firing order.

Up-dates coming.

Thanks again.
