Hey guys,
I dynoed my box monday. I dont think this is a thread yet so here it goes.

I've got 18" wheels, so I'm sure that didnt help improve my dyno results. All I have installed under the hood is a CAI.

Here's the results:


Got about 84-85 hp

I will be installing a MMW 4-2-1 header, and will do another dyno pull afterwards. We'll see what the header does! I'm doubting i'll get more than 5hp with it. Hopefully it will help with gas tho'.

 

Nice. Im running about the same. Good to know about what Im putting down. Im interested to see what the header does.

also, I have seen other header that have the collector further back than MMW. I know with v8, the further the collector is, the more power(within reason) - Hence long tubes always showing more power.

It would be very interesting to see someone dyno the difference between the brands.

 

Which header is that?

 

I beleive it was both the megan and the DC. Tried looking up pictures just now, could find any...

Does anyone that have either of these confirm the the collector meets at the flange?

 

Actually, I took another look at the MMW, looks like a really good design.

 

Its suppose to be pretty good

Here's a pic

 

Yeah, looks good. Tell us how the install goes.

 

All of the xB headers have the collector flange in the same position. They have to in order to connect to the downpipe flange.

 

Yeah, i was looking at a different pic. My bad.

 

Dman

is yours an Auto?

 

Yes, auto
why do you ask? does the manual have diff HP?

 

Less drivetrain loss, manual is normally around 10-15% auto is around 20%

 

Ahh, I see.
Still havn't had a chance to install the header. Hopefully tomorrow I'll get a chance.

 

Nice, looks like a pretty strait forward install. Header is very visable and accessable. Though I havent tried it myself.

 

yeah, usually the auto has less hp / for the reasons already mentioned.

If it was manual I would have expected maybe mid 90's hp

Thats why I asked, cause it would have seemed really low for a manual

Ok Fellas, I installed the header yesterday. Everything went great thanks to the tech write up for changing your header.
I plan on getting it on the dyno Monday or Tuesday.
I didnt really notice a big difference. I havn't got it on the highway yet though.
But the proof will be in the numbers. WE WILL SEE!

 

dont forget to get paid.

 

i wanna see the results i think this has been long over due just no one has had the cash to do so for the dyno runs.

 

Dyno Run TomorroW!!

 

YAY!
