someday we will get the microtech units out, damm aussie's

Chris...what do you think about the two charts?? Which car would you rather drive?

That AEM dyno is smooth as silk. They have my vote.

Chas, please explain to me using your infinite wisdom of turbo-technology how here SPOOL manifold in any way affected the power curve smoothness and the AF ratios.

FWIW, the SPOOL manifold she has on her car is a piece....it's got cracks all over it and is a horrible design. Even with it on their though the car still drives amazingly well I'd put more than a few dollars on Roni's car over that 200whp msp.

Infinite wisdom..uh...:rolleyes:

I thought Roni already got the Wagner Manifold already on (confused)

So think about it this way..

The mazdaspeed exhuast manifold is like one of those dinky straws you get when you purchase a mc donalds drink..

and the Spool/Wagner manifold as a garden hose.

It should be obvious that the garden hose will flow more water than the dinky straw.

The better the exhust..the more power you will get..faster the exhuast gasses leave the compression chamber the more horsepower you will gain..

well exhuast affects allot..if you have ever read maximum boost by corky bell..you would know that exhuast plays a major part when building high horsepower engines.

chas:D

Forgot to mention that with the larger exhuast manifold..you will be able to hit boost faster..which in turn builds more hp/tg down low.

Lastly don't forget..Roni has a T3...and the Mazdaspeed has T25..

Chas

I just Realized that the dyno i posted above..is not w/ the mpi tuner..it's w/ the stock ecu at 10psi!

Oops..my bad!

Chas

You need to read up more about turbo systems and dyno charts. The design of a manifold has NOTHING to do with the smoothness of the power curve or AF ratios on a dyno...it may increase overall power, but not by what you think.

p.s. Oh yeah...NOW you say it doesn't have the mpi tuner after everyone ragged the crap out of it....uh huh.

Rod, I understand you like the AEM, and it is a great looking EMS, but isn't that a little harsh ?

Bigger really isn't always better in an exhaust manifold design. You'll want small and well designed tubing to allow the gasses to exit with sufficient velocity. If not, I forgot the term, but the exhaust can re-enter the combustion chamber, and that's not wanted.

Did that come off as harsh?? I didn't mean for it to. I guess I just got a little burnt that someone was using false logic to try to explain why "their" product was looking bad in comparison.

I wish more people got a chance to see that AEM in person. I've known about it for some time now and it blew me away when I saw it mapping in 3D, auto-mapping, data-logging.....you should've seen how it easy it is to swap in the larger injectors and tune it for them. It took less than 1 minute and the curve was perfect with a glass smooth idle. That just goes to show all of those people who say that a car with bigger injectors won't idle right.

Can we try to act mature..we are having a discussion here!

Chas:rolleyes:

does the picture mean I'm not mature? I thought it was quite funny.

Why is the "CAT" circled?

I am horrible with p-shop....I was trying to replace "CAT" with AEM...didn't work like I had hoped. I saw the picture and it somehow felt relevent.
