We actually do make a 4-2-1 header for the xA/xB, check this thread:

*sigh* ...

so many things i want to buy...need to get some new tires first, b/c bridgestone OEM tires suck mouse nuts on snow... "all season" my as-stronaut...

 

just posting to keep in contact with this thread.

 

lookin good

 

I like it a lot. Keep us informed. Where is MMW located?

 

were in South San Francisco

 

so how do I get in on the group buy?

 

and when will the race headers be ready?

 

Damn.....Now only if i can find my Credit Card

This is one of the most well put together header i have ever seen, Hope i will have the funds to get in on this deal. In the event i do...were can i get in on the group buy?

 

the race headers are ready now..

 

You can sign me up for that price. Just keep informed.

 

Is it just me or is the base #s a lil low on that dynow 125/131??

 

Looks like it was done on a Mustang Dyno, they tend to read low. But the headers were tested on the same dyno, so the #'s/gains shown are accurate.

 

Aren't mustangs the loaded dyno's? I believe thats why they read lower.

 

yessir

Dynojets are inertial dynos, meaning they calcualte HP and torque by measuring the acceleration of a known mass. This does not accurately depict the type of loads you will see on a road, so it is best used for determining Flywheel HP through the drivetrain, and measuring drivetrain efficiency.

Mustang Dynos are load bearing dynos. They measure HP similarly tp an inertial dyno, except they use a brake to simulate the types of loads on the engine you would actually see on the street like weight of the vehicle. This type of dyno gives you a real world depiction (according to these dyno makers) of what you would see on the street. They are also the best choice for dyno tuning because they can simulate the actual loads you would see on the street.

 

Great info. Hurry up MMW, I can't wait to get this header.

Was originally planning on going Dezod Stage 1, however considerations in terms of hassle and possible problems unforseen, the facts: this is going to be my only DD for a while, it's easier to pay for things like cams, heads, individually instead of $5k upfront, and the tC is already a hell of a lot of fun to drive with other tuners on the street as-is... I'm going to go NA.

MMW Race Header added to K&N Intake, CC full exhaust, tweaked with a Camcon. Should be a nice little highway kicker on reg pump gas.

Then later on with some miles on the engine, do a rebuild with 11.1 heads, cams, springs, etc, retune and rock.

No woosh, but no possible headache besides the downtime for rebuild down the road.

 

we have a few different NA packages available now on our website.

 

That doesnt make any sense if they read low then why would the #s on the headers be accurate? wouldnt that mean the headers #s are off as well?

 

every car has different numbers, due to engine and type of dyno your using. Different dynos give different numbers.

What the main concern is the difference before and after a part was installed.

 

Well the #s are a bit to low imho all the tCs ive seen dynod have been in the range of 136-141hp and 143-147tq and this is more then one...but not sure may be just car...not trying to start anyhting just was wondering why it read so low thats all
