The Comp Cams Stage 1 Xtreme Energy Camshafts will appeal to the '96 to '04 4.6 liter owners out there who already have PI heads in place. Now the XE262 cams that we do have in this video will help deliver excellent low to mid range torque gains when used either with or without a custom tune, although expect bigger gains to be seen with those custom tunes. Now Comp does recommend upgrading both your valve springs and your retainers when running these particular camshafts which will of course add to the final price. But expect to be spending right around 600 bucks for the cams alone. Install is gonna get a full three out of three wrenches on the overall scale of difficulty from me, as this one is pretty in depth, but we will have little bit more on that later in the video. Now before I go any further, I do just really wanna hammer home the fact that these cams will only work on PI equipped 4.6 liter V8s out there. '99 and newer PI cars Comp states there is no modification needed to run these cams. However, pre-'99 PI equipped heads, Comp does specify modification will be needed to gain clearance between both the retainers and the guides. So you cannot run these in the '96 to '98 non PI GTs, otherwise you are going to encounter piston to valve issues, and not the good kind. All right, so now that we've gotten all of that out of the way, let's talk a little bit more about the 262s here. And honestly, guys, if you've done any research on cams, you've probably discovered the Comp 262s are a very popular cam for a couple of different reasons, the biggest of which being that nice fat power band with these cams, including a noticeable gain in low end torque. As far as some stats are concerned, well your effective RPM range with these cams will be between 1400 to 5400 RPM. And according to a lot of the guys running these things, they really do wake up the 4.6 without really having to rev it to the moon like you would with Comp's 270 cams. In short, the 262, in my opinion, is a much better cam for the street because of the gains that you're gonna see and feel light to light or on the track. But let's talk about how these cams deliver that power. And for starters, you're just getting more lift with the Stage 1 offerings. Five hundred fifty thousandths of an inch of lift for both the intake and exhaust cam, to be exact. Now for comparison sake, a stock PI cam is around five hundred thousandths on the intake side, a little bit more on that on the exhaust side, but at the end of the day, you're just getting more here with the Comp Stage 1 options, and more lift typically means more air into the cylinder, which means you're gonna be making more power. Next up, you are looking at 113 degrees of lobe separation and a duration of 226 and 230 respectively at 50, which is a considerable amount more when compared to the factory PI cam, which is about 192, 182 at 50 respectively. So more lift, more duration altogether will make more power, especially when paired with the better flowing PI heads. Now even though the Xtreme Energy cams from Comp do have a little bit more duration and lift over the stock cam, you technically don't need to run aftermarket valve springs. However, Comp is going to strongly recommend that you do and that you upgrade to their beehive style spring just to support the added lift. And I am gonna go along with this as well, because, let's face it, guys, you hate to do all of this work to the top end, skimp out on valve springs, only to break one down the road, drop a valve, and essentially kill your engine. So yes, there is gonna be a little bit more of an investment in addition to more work involved here with these added parts, but it's for the sake and the insurance of your engine long-term. Now as far as power numbers are concerned, well, that will be a little bit difficult to nail down because mods will be different, tunes will be different, but the popular opinion here with these particular cams is anywhere from 20 to 30 wheel, [SP] depending on supporting modifications, which is pretty solid overall. Now of course power should always be your first priority when shopping for a set of aftermarket cams like this, but of course the second big question I always get is just how are these things gonna sound? Will they lope at idle? And honestly, these cams will change the idle slightly, but don't expect that massive chop that you would otherwise get with the slightly bigger cam, because it's just honestly not gonna happen. But getting into the install, and as you might imagine here, guys, a cam swap is going to involve a fair amount of work. So let's just call this one a three out of three wrenches on the difficulty meter. The whole toolbox and anywhere from half a day to a full day in the garage, depending on your mechanical expertise. You're also gonna need some new cam bolts for the install, so don't forget to order those as well. Now if you are planning on doing this one yourself, a manual with all of the torque specs would be a great place to start, and of course highly recommended. You will need to remove the intake manifold, the valve covers, the crank pulley, the front engine cover, and also those timing chains, just to name a few before actually starting with the actual cam swap. Now if this sounds just a little too in depth for your knowledge, you might wanna leave this cam install up your local speed shop. All right guys, wrapping this thing up here. The Comp Xtreme Energy Stage 1 Camshaft will be for the PI equipped two valve owners who want a very streetable camshaft and one that will provide you with some good low end power, and you can grab your set right here at americanmuscle.com.

Sounds so sick
Wow what a huge difference! The car is a completely different animal now. Sounds so sick. Never owned a cammed car before but I love it!! Even with just stage 1 it has a nice chop at idle. It even changed the entire tone of the exhaust while accelerating. And I can feel the extra power I gained. I went with stage 1 with the beehive valve springs and retainers. I also changed the valve stem seals. You have to get ARP bolts for the cam gears too. But even at stage 1 it sounds aggressive. I love it!! That's how a Mustang should sound!! :DHelpful (2)

Stock Block Cam Swap
I purchased the Comp Cam Stage 1 cams after a lot of research. I wanted the best bang for the buck without having to invest in any engine modifications such as fly cutting the pistons for clearance. During that research I found that running a stage 2 spring or .600 lift spring (not necessary as these are NSR cams) along with new followers and lifters I would be able to rev the engine to 6500 rpm's on occasion without having worry about engine damage or valve float. Install went fine, remember this is a good time to replace the valve stem seals when you are in there. I noticed a difference right away and still waiting for a dyno tune. Take your time and plan a weekend, day one for tear down and prep, day two install.Helpful (4)

Comp Cams Stage 1
Under impressed. Minimal lope at idle and unnoticeable performance gains. Should have done a minimum of Stage 2. More than likely Stage 3 or another brand. Too much work to install for minimal results.Helpful (8)

There's more top end power and the car hasn't been tuned yet. You will need one though. They're not every loud but they are super bassy at idle. Over all well worth the money if you can do the work yourself or get it done somewhere relatively cheap.Helpful (5)

They are cool
I did the swap just cams no springs or those floater lifters my heads were milled but I hear some ticking noise but goes away I guess I should have gotten a high flow oil pumpHelpful (10)

I would make this your last upgrade on a full bolt daily driver GT beings horsepower gain is small vs the cost of cams and install time. Yes the cams have a nice choppy idle, shakes a bit at red lights and if you’re buying these for the sound then they will hit your target however they claim you will not lose any low end power and I found that to be a little misleading. While they do add what feels like 15 to 20 horses they seem to zap some of the low end (below 3.500 rpms) response out of the motor and it defiantly losses some grunt down low and I noticed this with 4.10 geared/manual I can’t imagine what a stock geared auto would feel like. You will want to crank in some timing advancement on your tune. Take your time on this install and expect some major lifter/lash adjuster taps on first start up but this will go away during warm up if all went well also make sure you order bolts for the cams (uses same size bolt as harmonic balancer crank pulley ford or feeBay has them) on the Romeo motors and order gears too if you have a Windsor motor. Don’t get me wrong I am enjoying these cams and they do pull noticeable harder from 4k to 6,300rpms but if you’re still running a relatively stock GT there are other upgrades that will yield nearly the same gains, cheaper and easier to install. Because of this I say get gears, handheld tuner, plenum, 75mm throttle body, under drive pulleys, full exhaust and such first after all that if you want more (and you will) then cough up the extra cash and buy these as they will be your last upgrade on a N/A motor stock block. This gets me to the point of cam choice. As temping as it is Do Not go for the stage 2 or stage 3 cams if you plan on keeping the motor itself stock and not building a race motor and here are some reasons why. First this is the only cam that you can use the stock valve springs if your motor is still healthy, this is the only cam that you won’t have piston to valve clearance issues, this is the only cam that can run on a stock tune but also can be tuned in great with a simple handheld tuner, other cams have major idle issues that will need to be worked out, any other larger cam will not make you faster than these on a stock block with stock heads and intake manifold. By going larger then these on a stock block you will just simplify lose drivability and have tuning issues to say the least. Bottom-line… Good cams. Sounds good. Runs strong. Price per gain hurts some. Will make you smile if you did all other bolt-ons first and ran out of options.Helpful (24)

Awesome Street Cams!
These cams are perfect for the street. Noticeable idle. Didn't lose any power or torque down low and they still scream in higher rpm's. These cams actually outperformed some custom stage 3 cams I had in the mustang. Will work great on stock heads and even better with trick flow 38cc heads or any ported heads. Just got my car back and put down 330rwhp/ 328rwtq on a stingy mustang dyno! Definitely a good purchase! The real question is what are you waiting for?Helpful (15)
If I were to get these cams, what else should be done to my mustang for these to work properly and sound great? If I were to get these cams, what else should be done to my mustang for these to work properly and sound great? This is for my daily driver and I am only looking at maxing out at about 400HP on my stock block and lower.
These cams would work fine from just installing them. I would recommend doing valve spring when you install these. Also to get the full effect of the cams you should get a custom or dyno tune.
Does this have a noticeable lope in the idle? I was thinking about purchasing these stage 1 cams because I want the significant increase in power that they provide. However, I'm not a huge fan of a very noticeable lump in the idle. With this being the stage 1, would the idle remain fairly constant and not lumpy? Or is there any video that shows the idle characteristics of these cams?
I'm running these in my 02 Crown Victoria P71 and the idle quality is fairly constant, it has a slightly aggressive lope but its only noticeable below 800 rpms or with a stock tune. Chances are during the dyno tune they'll likely be adjusting your idle to 800-850 anyways. If you're running an auto tranny, it isn't lopy at all when you're in gear at a stoplight, your exhaust will sound significantly deeper and louder too. Power is great from about 1400-5800 rpms, and since you're about 800lbs lighter than I am, I think you'll really enjoy these :)
What are the cam gear bolts needed? I am using the stock cam gears but i have read the other reviews and some have stated that i can not reuse the stock cam gear bolts. I am wondering where i could find and buy these new cam gear bolts?
If you need high performance fasteners, ARP is #1 in there field!
I own a 2001 Mustang GT with 4.6 engine. The engine has a 70mm throttle body, a cold air pack, an accufab plenum, and flowmaster mufflers. Will adding a Stage One cam put too much stress on the engine and drivetrain without making additional upgrades to the drivetrain?
Honestly, you can throw these cams inside an otherwise stock Mustang and it would work, so you're definitely fine.

Hi, To use these cams you will need to use Comp Cams Valve Springs Item# 30102.
We have not tested these cams with a setup like yours but do not believe you would have clearance issues, however with any Cam swap, we do recommend checking piston to valve clearance.
At this time we do not offer any cams designed for turbo cars. We would recommend a custom cam grind, or a cam designed specifically for a turbo car, as the turbo will perform best with cams meant for turbo cars.
The Comp Cams Stage 1 Xtreme Energy XE262AH Camshafts will work with both PI and non PI heads. Per Comp Cams: Xtreme Energy™ For 1999-up Performance Improvement Heads, Note: Can also be used in Pre 99 (P.I.) Heads with retainer to guide clearance modifications and COMP Cams® 26113 Valve Springs.
Unfortunately, these will not work with stock 96-98 heads. You will need to upgrade to 99-04 PI heads in order to use these Comp Cams.
The Comp Cams Stage 1 Xtreme Energy XE262AH Camshafts will work for your Mustang, however we would recommend replacing the headers and throttle body for the best performance.
