Default Any one try a hood scoop with twin k&ns.

I was dreaming the other day while looking under the hood at options for cold air intakes. I am just a rookie at mods but it looked like it would be possible with just a small amount of body work. What do yall think would look cool and what gains could be expected.

Probably nothing better than a C32 or V8 airbox couldn't do (on the Limiteds). Plus hood scoops?? They can be hit or miss and if you miss you have to replace the hood which cost a pretty penny.

+FIREAMX has put a scoop on his and I believe there are pics here somewhere on the forum.

i was thinking the same thing the other day...watching top gear and looking at the astons and jags. they have the long cuts in the hood not the scoops. im thinking that would look clean and nice on the xfire...let me know what you think...this might be a project that i would like to try.

I've been keeping my eyes open for a used crossfire hood just for this reason.

You could practicall 'force' the air into the air boxes with a small pair of scoops on the hood.

You would then need be limited to the restrictions just past the airbox...and you may even end up throwing codes on the Non-SRT model (too much air).

Shawn: You are thinking along the same lines... I'll post some photos eventually... There is a very direct path to the throttle body... It's hard to explain right now, but it involves a scoop and filter directly above the TB inside the troff where the windshield wipers are... It's a straight shot with maybe 6" of tube that rams air from the windshield / hood juncture...

Never even thought about checking the clearance in that area...but that makes a lot of sense (at least on the SRT, I'm not sure where the air enters on the N/A cars). I guess the main concern at that point would be water intrusion for those of us who have drivers and not race cars. Although, mine doesn't see rain anyway, but you never know.

Keep us posted! I'll have to do some investigating when I get home..

The direct flow into the throttle body would be one like that of Vipers and Imprezas. I'm sure it could yield better results but still, hacking up your only hood is dangerous.

Definitely try to find a wrecked Xfire with a striaght hood

If it's legal in your state to drive with the hood removed, remove the hood and quickly mock up a scoop to direct/force the air straight into the t-body and see if there's any changes/lights etc.
An easy day project, with minimal cost - should take less than a six pack of beer!!!

I know some others who have the N/A Car and not the SRT are having trouble with check engine lights and rich running engines when they add cold air kits. I'm not sure how the N/A car is setup, but I believe there may be a MAF sensor or something mounted before the throttle body which is throwing the code.

An ECU tune may be able increase the allowable parameters of the meter and prevent the codes.

If anything it will run lean with too much air... but it won't... MAF MAP IAT TPS 02's are all interconnected to adjust the timing and fuel flow... Sad but true... The car will maintain 14.7:1 no matter what you do to it !!!

Is this on the SRT or the N/A car?

I could've sworn I read someone having trouble with a CAI and check engine lights, running rich, and multiple codes.

Biggest advantage will be the clean cold air, the "ram" effect is quite small unless you are above something like 100mph. Also the ram intake design needs to be good, otherwise it will cause more drag than it adds in power.

If the Crossfire ran a MAP sensor I doubt a RAM could generate anything near positive boost to generate fault codes, but I think the Crossfire runs only a MAF sensor and as HDDP says the ECU will crunch the numbers and control the A/F ratio. Not sure it aims for 14.7:1 at least on the SRT that wouldn't be wiseor help power, but with only narrow band sensors perhaps it does??

edit - noticed from the DTC list that there are codes for MAP sensor so it's there as I say above, ram effect won't generate positive pressure, would be interesting to log the data from it with and without the ram.

IT was me but I am not the only one... I can not remember where I posted about it...HDDP knows a lot more about both engines then I do but my general knowledge was I built the intake, put it on two days later tripped a code. Went into the dealer had the code run and reset. On the way home tripped again... Went back to the dealer said it was still running rich.. Took the intake off never tripped another code. I did not beat on it while I had the intake on either so running it hard and turning it off was out of the question which is what they accused me of.

Does the car in your avatar have a hood scoop(s)?

I agree...they don't look right if they aren't made right.

There has to be another reason you thew a CEL... I would guess it has to do with the MAF... I ran the CRAP out of mine with a really poorly designed CAI and the only time I threw a CEL was when the MAF popped-out of the intake...

PS: how did you know the engine was running rich ? Did the dealer do a AF ratio on a dyno ?... Or were they just giving you BS excuses ?

They plugged in the DRB3 or what have you and came up with that reason. It could have been the MAF sensor was not as sealed as I would have like it to be with that design. I needed a bigger ruber gromet.
There are others on her who are using the stock tube with the MAF in it from factory and they were also tripping codes.

you need to go onto Ebay and get one of the guys that sell the Carbon Fiber hoods to help you out.
I've been down this road when I had a custom 3000GT hood made.
Before they could begin making the mold they had to have their costs covered. This was done by starting an "initial group buy" .. We got 10 or 15 people (can't remember it was a while ago) to pay up-front and they made the hoods for us. I had to tell them, in detail, what I wanted and drew some rough sketches of it as well. The hoods came out perfect.
We basically took a 1st Gen 3000GT hood and made it look like the 2nd Gen hood. The first gens had these goofy bolt on bulges to allow more room for the struts while the 2nd gens had the bulges as part of the hood with nice smooth lines, and a higher bulge in the center as well..
If they can do somehtig as difficult as taking 2 hoods and merging them into one hood I'm sure they can make a Crossfire hood. If you can get them a Used Hood, rather than having them buy one from the dealer it will cut your initial costs a lot!..
I would try K2 Automotive from Ebay, they are pretty good and have a lot of pull with the manufacturing company that makes the CF hoods.
Oh, and if you'd rather have Fiber glass it's even cheaper.
