Dyno Header
So I've been doing a lot of work trying to get the motor ready for the engine dyno. Here you can see how I adapted the bell housing to the dyno cart.



once mounted

I realized I had a BIG problem

DOOOOOH!!

So I went to see Carlos from CLR to borrow his dyno header but it turns out his header had flanges that fit the Mazda Motorsports PP housings. So what do I do?
I remembered I had a few ubends and flanges laying around and I was able to throw together a quick dyno header.



After a few hours this is what she looks like, not my best work but it will do.

Now I just have to wait for my place in line at the dyno shop, should be a couple of weeks. My goal at the dyno is not to come home with a number, it's strictly for break in purposes. Of course I'll be tuning every damn cell on the map.

Why not just hook up a starter, radiator and fuel and break the engine in the mean time on your little stand while you wait for the dyno? Building a home made test stand is fun as a ****.
a couple of reasons: the cart won't accept a starter without major hacking. If I did this it would only idle and rev which doesn't really break in the motor, you really need to put a load on the motor to break it in.

Well guys here is the finished product


Here is the adapter I had to machine to attach the engine to the brake on the dyno, this was more work than the headers.


hopefully the next post will be from the dyno.

she has a heart beat!
Well boys and girls the time has come. After weeks of preperation (header, dyno adaptor, wiring yada yada yada) she finally came to life. It wasn't easy, you'll never really know what it takes to dyno and engine until you do it, the preperation that is involved is amazing. I'd like to thank my friends for all of their help, specifically Laz, Mandi, Jorge and Nory.
Once we entered all of the pertinant info into the AEM she fired almost immediately.
Here's a small taste
here she is waiting to be started

here's a small video of her running!

Guys, thanks for the kind words!
Below is a pic of the header in its full glory, we spent quite a few hours on the dyno breaking this thing in. I need to thank my friends for all their help Laz, Mandi, Jorge, Nory and Eddie.

Awesome someone finally put leds in their exhaust. LOL! Seriously though, man I wish I could break in and tune my own engine in this fashion.
BigAl,
You probably already have one but the picture really shows the need for a heat shield protecting the intake pipes!
Great Job Al!

You are correct Barry, I do have one, except it's made for the header that is used in the car. Remember this is the dyno header which is completely different.
Below is a pic of the shield. I just couldn't justify the cost of the material for just the dyno header.
