CP-E FAQ

CP-E's Website
http://www.cp-e.com

Last sunday (more then a week ago) I dropped off some manuals to CP-E for the shift kit they're working on for the Jatco. While I was visiting their awesome shop, they gave me their intake and let me use the shops facilities to install it. (Very nice of them). Josh even checked over my wire installation while I did some cleanup on their laptop machines (my trade is computers, not cars). Here are my comments on the system now that I've had it for a week.


Installation Pipe:
The intake section installs just like any other cold air intake. The primary differences are the heat shield (the other intakes don't have one) that serves to hold the intake in place, and mounts to the area over the wheel well. CP-E has you slit a vacuum hose to wrap around the opening to help prevent the pipe from rubbing. I'd recommend you either glue this vacuum hose, or use some electrical tape to bind it to the heatshield. (Some people have reported it can come loose if you just leave it on the heatshield without some sort of attachment device). The heatshield is quite cool as it has allocation for both VAD solinoid mounting, and some tiewraps for preventing the ABS harness from rubbing against the pipe.

The piping is very sleek, and bends much less then other 6s CAI's. The install actually has you push back the battery some so the piping is completely clear of the battery. Its got about one less bend then the injen intake, which makes for a very clean looking pipe. The way the hoses are routed as well help to clean up the install. I felt the vacuum line was a bit loose so I just flipped the check valve around instead and left the hose unattached. Individual results may vary. (I'm sure it would stay on the nipple, I'm just paranoid and pessimistic, as everyone knows)



Make sure you follow the instructions carefully for the PCV hose, as any kinks in the hose will cause some interesting issues.

The filter for the CP-E unit is rather small, but keeps the primary intake rather high in the wheel well. I replaced the stock filter with a 7 inch powerstack S&B filter, which drops the inlet down to the insert opening. Because of that I had to put the original insert back on, as the filter was getting excessively soaked from incoming water. If you want to replace the filter, I'd probably go with a 5 or 6 inch S&B powerstack instead.


Installation Mafci:
CP-E's instructions for this section are VERY good. It is pretty nerve racking to pull your pcm harness apart and splice wires though :). I just took my time (an hour easy) to slowly seperate all the necessary wires and splice them as instructed. Its quite hard to seperate some of them, which is why the excessive amount of time required. Take your time, and take breaks, and verify verify verify. Make sure you have a good set of pliers to ENSURE that the splices snap down properly. Josh was nice enough to finish up this install for me, and mount the Mafci under the dash for me (while I worked on their computer system).


Initial Remarks:
The induction sound of this thing is incredible. Its hard to describe. Its just "holy !#@$! what was that?" sound that comes outta the engine when you tap the throttle and let go. Its basically the sound of air screaming in horror as it gets sucked into the intake manifold. Very deep sounding.

Before anything else, the sound on this thing is incredible. It sounds far better then any exhaust I've ever heard for the 6. Its deep, its loud, and it screams power. Anyone considering shelling out more then 400 dollars on an exhaust, should consider the CP-E instead. The sound is THAT good. Completely changes the audio dynamics of the car...makes it more of a lion instead of a small upset buffalo.

Inital Driving Impressions:
Is this my car? I'm sitting here in 2nd gear trying to accelerate and laying down a strip of rubber. Go one wheel drive!!! I left the CP-E bay, warmed up the car a bit, turned the corner and slammed on the gas, and had wheel spin up the wazzo, followed by torque steer, followed by the intake hitting 5000 rpm, followed by a surge of acceleration, followed by visions of moose suddenly in my headights, followed by lifting the throttle, almost spinning out, and then regaining control of my sphincter.

Low end throttle response is fantastic. Its almost instant. Power from 3k+ is much stronger then stock...at around 4500-5000k the kick from VVT is very apparent, and heavily exaggerated from a stock car...so much so that if you let off the gas in the MTX, the engine actually "JERKS" from the sudden drop in torque.

This is more then just a power upgrade...its a "look at all the shit I have to buy now to properly use this thing" upgrade. I don't see how you could drive on stock tires with this thing...cause I'm running T1-S's and I've still got wheel spin issues under heavy acceleration. (Of course the fact that its below 50F around here doesn't help any).

I'd consider that if your thinking of the CP-E, to consider it along side a wheel/tire upgrade, and possibly a wishbone mount bushing upgrade as well (to lessen the effect of the engine torquing on the overall dynamics of the vehicle).

Final Notes:
CP-E places a warning on the package that the car's dynamics will change with this intake's installation, and to please take time to relearn the vehicle before attemping previous manuvers with your stock car. They aren't kidding. You'll need to adjust shifting points, switch to M mode in an ATX, and be very wary about lifting the throttle in a hard turn.

This is quite possibly the best mod I've experienced for the 6 thus far, baring the addition of lightweight wheels and performance tires. I'd rate the CP-E as one of top 3 mods. (Wheels/Tires, Shocks/springs/coilovers, CP-E).

With the considerable support offered from CP-E on their intake packages, I don't see any reason to hesitate buying this product. Anyone whose had any problems have had them solved by CP-E, and/or if you aren't 100% satisified with the product they'll even work with you to either fix your satisfaction level, or refund your purchase. You really can't ask for much more out of a company.


Secondary Benefits:
Though I've only done a single tank of gas since I installed it (so take this information with a VERY tiny grain of salt), it appears that my mileage has improved about 2-3 mpg. This I find surprising since I've been "enjoying" the intake whenever I've got an obviously clear straight road ahead of me. Grain of salt though...I'll post further impressions on mileage after a month or two when I have enough data to warrant further discussion. Till then, once again, take this information (Mileage benefits) with a grain of salt, as your results may vary.

I'm still trying to get use to the new power band. It like learning jow to drive it all over again. On a side not don't get lazy and only put 1 screw back in on the bottom of the wheel well cover. I had only one screw in there because i have been test fitting fog lights for the sports bumper and well the screw on the drivers side came out today and my tire burned a giant hole in the cover.

Crossbow-
Quick question for you. When you installed the intake they have you attach the AVX (thats not the name for it, I don't have the instructions infont of me) sensor to the heat shield. When you attached it did you just cut off the two vacuum hoses that were still on it? They used to go to the stock airbox. Also where did you mount the MAF Customizer? Mine is just sitting by my left foot right now. Thanks.

I didn't cut off the two hoses, I just removed them. I think I might have plugged off the ends with electrical tape (from the removed hoses).

As for the maf controller, you can mount it to the beam under the dash, either with tape, double stick tape, or velcro. I wouldn't put it on the floor, as it would be far to easy to accidently smack it with your foot.

Low 6's in the 0-60, and probably 14.3-14.4 n the 1/4. (in a 6s MTX). This is of course as long as traction is available.

But since these are numbers straight outta my ass, you'll have to wait for actual confirmation from the drag racers on the forum like atl, mmfarn, whodiddy, etc etc.

I'd give you some gtech times, but they'd be heavily biased due to the fact its only about 40-50F outside now...10F less intake temp =1% more hp.

How about the Approx 0-60 and to 1/4 mile time for ATX with this CP-E?

I meant mmarfan (sorry for mispelling) heh.

Kryptoknight,

Add about a second to each, and it'll be about right...low 15's for the 03/04 6s ATX, with a high 6 second 0-60.

This is assuming you don't have something like the CP-E shift kit or aftermarket torque converters.

were the splices cheater splice (plactic piece you slip wire thru and push metal tab down)?

So will the CP-E intake and MAf thing void my warranty or what?

blackmagik,

I learned early on that its usually not a good idea to leave any sort of opening in a vehicle uncovered. Little critters tend to make homes in vehicles, and the last thing you want is a spider bite cause you didn't put a piece of electrical tape over the hole :). Plus sealing holes prevents moisture from generally getting inside otherwise known as a car's worst enemy.

Da6,

I don't know if their cheap or not, as I don't know too much about electronic wiring. They're red, with a slicer in the middle that you clamp down, then insert the MAF plug into. Maybe someone can snap a photo for you.

EmcNeice,

Its like any other aftermarket modification. If it can be proven the part caused the failure, then yes, it'll void your warranty on those respective parts.

Since this modification causes a rather drastic increase in power, it can effect pretty much everything involving the drivetrain. Usually if your worried enough to be asking the question, you shouldn't do the mod.

I'm wondering. Will the S&B filter throw off the tuning of the whole system that was developed by CP-E? You would have thought that they would have gone with the S&B to begin with.

I doubt that the filter change would have any impact on the CP-E tuning. The intake tube diameter has not changed.

As long as the S&B filter doesn’t introduce an erratic disruption to the airflow (which may confuse the MAF), which I don't think it would, I don’t see it impacting the A/F tuning.

I had issues installing my CPE system, and Anthony was available to answer my questions well past midnight. Even friday night he said he was available till about 2 or 3 AM in the morning if i had problems.

My issue was the PCV hose was pinched causing some sort of pressure build up in the engine, which i should have checked more carefully before going through other trouble shooting over the phone with him.

The only other problem was after fiddling around with the pipe and getting the filter all set, the tubing i put around the heat sheild came off some and the pipe starting banging. Talk about fun, squeezing a screw driver in around the tubing to get it to pull up and fit back around it.

Besides that, everything went great... till my clutch went out last week which was repaired under warranty even over the 12000 miles. I did remove the intake, pulled off the MAF custimizor and left all the splicer things. Just had to create a connection with male to male connections to reconnect where the one wire is cut. And after i get my bumper replaced due to being rear-ended on the way to the dealership to get my clutch fixxed, ill put the intake back in :)

Carlomagneto,

I haven't noticed any irregularites in idle, power delivery, or any indication of a problem.

The stock CP-E filter is just dandy, I just felt it was a little on the small size. (Plus I'm a paranoid freak).

The only difference I've noted between the two is that SnB is even louder :). I did it primarily for increased filtering surface area, as conical air filters really aren't a source of intake restrictions. (Aka don't expect more power from an SnB).

The disadvantage of course is with a 7 inch powerstack, it falls below the insert...exposing the filter to direct air inlet if you remove the cover, or use a 6 wagon style. The CP-E sizing keeps the filter high enough in the wheel well to prevent direct exposure.

I was wondering if the acceleration remains as smooth as stock? The one thing I do like about the 6 (low end torque and all) is the very smooth acceleration. How does this system affect that?
