Hi everybody,
I am fairly new to the site and a fairly new crossfire owner. I have a 06 roadster that is completely stock. I would like to boost the horsepower and still maintain good mpg. I have thought about adding Needwings CAI, cooler plugs, a Eurocharged tune, and maybe a borla or magnaflow exhaust. Not for sure about the exhaust yet. May be too loud for the roadster. Anyway I would love to hear suggestions from the group.
Thanks
DarcyD

 

+ on the CAI and EC tune
- on the colder plugs, not needed

other suggestions : 74 mm throttle body ( do this before the EC tune )

as to exhaust, nothing there for additional HP, just whatever floats yer boat sound-wise.
I have the OBX catback ( Chinese Borla ripoff ) and I'm happy with that on my roadster.

 

That OBX doesn't have the loud drone noise? Thanks for the advice

 

ALL of them have a drone noise, including the OEM.
It's the level of drone, and if it does or doesn't get in a harmonic with some other noise that counts.
The OBX Racing cat-back has a resonator in line before the final muffler ( like the SRT6 has ) that seems to tame it somewhat. There are videos of when I installed it :

Awesome, thank you

 

So you increased HP and MPG with these fixes?

 

I have been reading other posts and have another question. When I get the 74mm throttle body, shout I also get another MAF elbow and housing or use the OEM elbow and housing.
Thanks

 

Oem Elbow... clearing the vanes out doesn't hurt.. and the larger housing basically let's you take full advantage of wide open throttle.

 

Hey all,
I am having a hard time finding a 74mm throttle body. Anybody have any good sources they would be willing to share?
Thanks

 

the one below at car-guts.com looks pretty good.
give them a call and make sure that A 113 141 0125 is the part number on the black cover.

here is the tutorial : https://www.crossfireforum.org/forum...ade-guide.html

 

Hmm.. easy find on Ebay..

Yeah I looked on Ebay and did not have any luck. I will keep checking though.

 

It's there DarcyD..go to the website listed by Mrmiata...I did this mod and it worked great...I did use the OEM MAF housing with the 74MM body and it works fine...I can feel the extra "pull" during acceleration ...good look....Carl

 

Was going to say.. 44 bucks and free shipping .. how much more luck you need? LOL

 

Thanks MrMiata,
I was at work and only a part of your post was displayed. Thank you for the help. Just ordered it and it is on its way!

 

Some have re used the O ring gasket.. but they are cheap enough @ 10 bucks.. Just wanted to throw that out since I don't know how much homework you've done so far..

 

I am going to the auto parts store tomorrow. Thanks for the help. Next is my CAI from NW and then the tune from EC.

 

You will absolutely love the extra kick from these..!

 

The sale has ended on your link, Greg, but here's one even cheaper ( I'm sure that will warm the cockles of you heart ) :

You had been looking for a mesh windscreen . . . Did you order one of those mesh windscreens from Germany??
