Stage II Carbonman IM

[jayupark]

I installed it yesterday... Sorry, I totally forgot to take pics. I was going to, but I ran into some lost nuts and bolts difficulties, so I got frusterated and forgot about the pics...

The runners on this thing quite a bit larger than stock :D

My initial impressions were "this thing does not suck enough", because I was driving around the city from stop light to stop light. Honestly, I could not tell the difference.

However, when cruising at any speed in the 2K-4K RPM range, I could feel a HUGE difference. It feels like I'm being pulled by a rope tied to the front of my car. It's hard to describe the feeling... big increase of midrange HP and torque I guess.

Oddly, I don't feel any difference at WOT acceleration.

thats good to hear, im waiting for mine to be delivered

[KeWLKaT]

Good stuff.

[joph09]

did you reset ecu? sounds like a quality product

[chris929]

one of you should dyno before and after :D

[04GTboySC]

we dont think about it before we do this modification lol i know i forgot to

glad you got it installed dude i've enjoyed mine since i put it on last year

[Corey Johnson]

would love to dyno, but i live in north dakota...im not even sure where i could find a dyno, but ya that would be sweet.

pics ??

FINALLY!!! i installed my stage 2 p/p manifold, looks great but i really couldnt tell what the performance was because its about 95 degrees and humid today, so im going to wait and see when the weather cools down a bit

ps. for whoever was waiting for my stock man., i will be sending it out tomorrow back to craig...sorry if inconvienenced anyone...my bad.

ive never added pics before so if these dont show up, then i need help

[Corey Johnson]

ya it worked, could have used some spacing though, but o well

[ArunSenior04]

Awesome. Get that sucker shipped back to Carbonman so I can get mine lol.

Finally some pics, thouse are some big *** ports. Very nice!

[Jonny666]

Is this stage II supposed to be acid ported?

[slow 2K2GT]

I believe so, but its mostly to remove the casting imperfections deep inside the manifold that normal porting cant reach.

[Jonny666]

I thought acid porting didnt do that, its supposed to leave the surface exactly the same and just enlarge the opening. that's why it'd be so great on our manifolds... cuz we cant get far enough into the runners to do a really good port job.

[slow 2K2GT]

thats kind of where I was going with my post, perhaps its to early for me to be typing.

[jayupark]

yup, the ports are HUGE, but the surface inside (as far as I could reach with my finger) was still a little rough.
Midrange it pulls nice and hard, but there is not much of a difference off the line.

[Jonny666]

I would assume that you are now restricted by your stock throttle body. If i were you.... i'd go down to princess auto and buy 2 crappy vaccume gauges. hook one to the manifold and the other to your CAI right in front of the throttle body. see if there is a significant vaccume drop right after the throttle body.
It may be time for a 58 or 60mm TB....

a little bit of texture is good for fuel atomization. :)

[05xd]

Is there anyone that has dyno'ed this intake yet? I can't justify spending a few hundred bucks for 4 horsepower.I have a intake sitting in my shed ready to go when I see numbers

[Jonny666]

a little bit of texture is good for fuel atomization. :)

Our manifolds are dry so the texture does not help fuel atomization.
Therefore you want it to be as smooth as possible. a polished manifold will flow like a whopping 2 or 3 % more but hopefully it'd make a differance.
the fuel is not injected untill just before the intake ports on the head.
