I have read allot about people doing cold intakes on the SRT and Non SRT's. So my question is: Does the Cold Air intake give a standard crossfire any extra power? Does the cold air intake give the SRT extra power. If so why? Most cars I have had in the past have benefited from a K&N cold intake kit. Why wouldn't my new love?

Thanks,
Rob

 

Your car already has a CAI.
Open the hood, and you will see two air intakes, one each side of the radiator, going straight back into the t-body.
Cold air is more dense than warm air, that is why CAI's give you more power.
At least install K&N's on your car if you haven't already.
You say you've read a lot about CAI's on the Xfire, if you have not read them on this forum I suggest you do so, there are many threads discussing the pros & cons and everybody has there opinion.

 

After removing my grill for a close look-see, there really isn't a good way to install a true CAI on the xfire, except with a whole lotta' modification. I drove my car around for 3 hours with a Fluke DVM with a K-type thermocouple snaked under the hood and the breather snorkels removed. The TC was placed where the conical filters are usually placed in the pics I've seen. My observations were:

Ambient temp: 76 deg F

1) at idle (Hole Shot) the intake air temp rises quickly to ~145 deg F. I imagine due to the lack of wind (driving) generated cooling.

2) 30 mph. In town cruising. Leveled off at 120 deg F.

3) 55 mph. Local town road. Leveled off at 95 deg F.

4) 75 mph. Interstate. Leveled off at 90 deg F.

I have to agree with most folks here on the Forum:
A CAI on this car would really work better if the filters could be placed in the space between the radiator bulkhead and the grille.

Good luck!

 

Yes it does, there is not a lot of modification needed.

I have relocated the filter into the lower grill with NO MODIFICATION other then tubing and it is a noticeable power gain.

 

you could try evosports phenolic spacers on the manifold, this will stop the heat transfer from the engine block to the intake manifold.

 

.I have read the threads you refer to. That is why I started this post. It seems like everyone has their own interpretation on whether or not removing the stock air box produces power. Like I said in my previous post. All of my previous cars I have added the K&N cylindrical filter and have always felt an improvement right away. It seems better air flow usually means more horsepower. That is why I wanted a straight answer. What works Dual K&N's, Single K&N's, Stock Airbox or Stock airbox with standard K&N's? Maybe leaving the car bone stock is the best answer. Thanks for helpful replies.

 

Stock Airbox limits flow. And Dual K&N's on the end instead of the tubes eliminate the CAI effect.

The best options I have found are a V8 airbox with stock tubes, or a 3" CAI with relocated K&n filter. The former looks less tuner, but has increased turbulence and a slight loss of torque. The latter has a smoother flow and better filter location.

I had The V8 Air box and now have the CAI. The airbox cost me around $250 shipped and the CAI I made.

You'll be looking at anywhere form 5-15 hp gain depending on other mods and which you choose

 

How did you guys miss this thread... https://www.crossfireforum.org/forum...ad.php?t=18345
I think I'm going to run the M113 air boxes with the vrp carbon fiber air box and filters for about $1,000 used it has produced a little over 25 hp with the tune. I can't see spending $500 on something I could tig weld up myself.
HERE is the VRP air box and intakes...

 

with a tune eh? so that means its improving the airflow enough to make another 3-5 hp kinda pricey. the bosch tune cost only $600 tops and yields 20 hp.

 

Not if you do it all at once I will have my car stored for the winter so im going with the ASP pulley, VRP air box, and possible the SI or Veloce tune which ecu alone has shown higher gains then renntech and evo.
www.VelocePerformance.com they were just having a 15% off sale so rough cost of $900 dollars but if we could get a group buy going we could all get the best tune for cheap pricing...

I missed typed that as well all the results I have read have been after people have had the ecu tuned BUT the air box yields 15-20 horse alone with the complete kit. Sorry for the confusion it is the same as the RENN-TECH box for $2,500 less here is what it looks like with the tubes...

 

I'm sorry guy, but I just can't imagine the carbon fiber airbox giving you another 15-20 hp, the stock version might be a little restrictive but it's not that bad. I smell BS. Maybe you can post a dyno after your full tune.

This is going on a stock crossfire right, and not the srt6? I think with just the SL55 y pipe on the srt you can pick up 15 hp for only a $45 part.

 

I seem to remember back when a forum member was getting his car tuned at Speed Innovation that they ran it on the dyno with the engine cover off and there was only a 5 hp difference. If I find the post, I'll link it.

 

The air boxes are simply CF pieces over he bottom piece of the air box. There's a huge write up on mbworld.org about the testing they did with it.

Also, 25 hp with a box and tune for $1,000 is pretty pricey, considering that last 5 hp is costing you like $500.

 

A word about our cars and the Mercedes Siblings...

I used to have a friend that worked at a Aftermarket/Tuner store in Orange County for BMWs and Mercedes. Those people generally don't have a problem dropping big bugs for small gains or anything that will make the car look/sound more aggressive and remain classy.

Good example... The shop was sent like 7 different exhaust for I forgot which car, some of them being around $1,600 and none of them made more than 7 RWHP over the stock system. They had bigger exhaust tips in pretty chrome and sounded beefier. Again... as a rule of thumb once you get over/near 300 RWHP things start to get very expensive.

For anyone who removes the heads or does an engine break down - Ceramic Coating the pistons heads and valves should yield 15-25 horses and not all that expensive if you're already doing a breakdown.

 

I think most of the N/A crowd is looking to get closer to the 200 RWHP mark first...

 

Is that because the ceramic coating is increasing the compression ratio in the cylinder?

 

IT is so much reading I tried to find the dyno but got tired of looking here is the link its all you... And it will be for my srt6 as long as it clears the fire wall...

When switching to a CAI on a normally aspirated car you should see slight gains. When adding one to a forced induction car your gains will typically be quite larger. This is due to the fact that with the addition of a turbo or supercharger more air is being sucked into the engine. Most OEM filter systems are restrictive, actually all of them are restrictive. Anytime you make it easier for a supercharger or turbo to breath in the air the more power you will free up.

I would have to say that our car has a ram air intake, not cold air. Every CAI out there places the air filter outside of the engine bay. Since our OEM system places the filters right above the heads they are constantly heated. When the air enters the intake tubes they pass through the heated filters thus increasing the temp. Basically those filters are acting as heating elements.

The gains they got were from the V8 cousin to our engine. Therefore you will not see the same increase on the smaller V6. Something more accurate would be 12 or so [provided that you own an SRT-6]. Still a good increase but I would look at Needswings intake. Here are the benefits, approx. half the cost, proven gains in power & you would be supporting the companies that are dedicated to the further development of our cars - lets keep them in business! Plus it is an actual CAI.

 

No, it works to prevent hot spots from developing on the pistons which can lead to detonation.

Maybe on a big inch Chevy, but not on a 3.2 V6.

 

oh OK then that makes more sense if these hp claims are made on the supercharged cars, yeah the stock srt inlet is restricted, which is why everyone slaps on the sl55 y pipe. that part makes another 15 hp for only $45.
