SOHC Cam Specs

Post by neonrt_98 » Thu Oct 20, 2011 7:35 pm

I gathered a few SOHC cams to compare actual lift and duration since stock cams are measured different than aftermarket. The aftermarket cams I checked were as they were listed. I need to find a '95 cam to get the actual specs from it. I was surprised to see that the '02 Magnum cam measured the same as the Crane 10. I always assumed the Crane 10 had more duration than the Magnum cams. I'll finish the chart when I get time.

Image

Ok I added the larger Crane cams to the chart and listed as to which they are with the old and new part numbers.

Crane 16 = old Crane #4
Crane 18 = old Crane #5
Crane 20 = old Crane #8
Crane #7 has the lift of a Crane 14 & Crane #4/16 but the duration of the Crane #5/18

Image

I tried to put all the cams on one chart but for some reason on this forum it kept making it small.

Agreed and done. Great info :thumbup:

Ok, I updated the charts. I need to find a '95 cam so I can get the specs for it and I need to check one of the stock cams I have.

Ok so I'm a little confused would the Crane 20 work good in a turbo set up the advertised duration is 280 intake 285 exhaust but at .050" its 236 intake 230 exhaust they(Crane) said it is the best turbo cam available

Yes it would be a good cam for a turbo set up. Yeah there advertised durations are measured different and I don't have all those cams or time to get the advertised duration. They just use the advertised duration numbers to make the cams look bigger for sales purposes. If I get time I'll find out all the advertised durations at the same point to make them more comparable.

People should also know that with the crane 20 you need 6mm lash caps along with all the normal stuff like crane springs, retainers and such not to mention ms

The Crane 005/18 & Crane 008/20 both require the Ferrea C10008 Lash Caps.

P5007030 Mopar Performance cam

Adv. Duration:

Intake: 232º
Exhaust: 260º

Duration @ .050" lift:

Intake: 170º
Exhaust: 192º

Centerline: 114º

Lobe lift:

Intake: .279"
Exhaust: .272"

1995 advertised duration:

Intake:216.8º
Exhaust:229.1º
.5º overlap

regular cam is
I: 207.2º
E: 229.1º

So comparing MP lobe lift to the '95 advertised above, ther is no way the MP cam is the 1995 cam as ppl claim. It may be close in duration, but the lift is a lot higher. IDK what the SOHC rocker ratio is.

If it is near 1.5 (by guestimating from the '01 mag specs), then the MP cam has some healthy valve lift.

The P5007030 Mopar Performance cam is the same as the '01 Magnum cam. Those specs the factory gives is totally different from what it would be if measured the same as aftermarket companies. That's why I was measuring all the cams the same so they would be easier to compare to each other.

The P5007024 Mopar Performance cam is the same as the '95 "hot" cam.

I would like to offer up cam specs if I can get my hands on a degree wheel. I will be putting a spare modified head in my '03 and also a '95 cam. I'll try to get the wheel before I put the head on, then I'll pm you the specs.

Well I'm not going to argue, but with a lobe lift of .222 and .207, the '01 Magnum cam does not match these specs. The .org's pic does not show specs. I am not going to purchase the cam to verify the specs either, and don't know if anyone has. Summit racing list the valve lift as similar to the '01, but who knows if they are correct. With the shown specs, it puts valve lift somewhere in the .400" range.

I can't see any other real reason why they tell you to use the high lift springs, if it is "just a Magnum cam".

I wouldn't think they would risk their reputation by giving false specs.

They likely put the specs there to disprove the false info being put out there. I'm sure it was hurting sales.

The P5007030 is cheaper than the '02 cam, and the '01 is not available anymore. So if I were in the market for a little upgrade, I would prolly buy this.

The info is there, you decide if MP is lying...

stock cam specs

Post by RSwain » Sat Apr 21, 2012 3:39 pm

Okay, I just degreed my 95 and 03 cams.

95 cam:
cam lift at intake: .188"
cam lift at exhaust: .177"

Durations are all measured at 0.050" and are presented as degrees of crank rotation.
Intake duration: 156 degrees
Exhaust duration: 162 degrees

Lobe Separation Angle (LSA):
104 cam degrees

2003 SXT cam:

cam lift at intake: .172"
cam lift at exhaust: .177"

Durations are all measured at 0.050" and are presented as degrees of crank rotation.
Intake duration: 148 degrees
Exhaust duration: 168 degrees

Lobe Separation Angle (LSA):
118 cam degrees

I hope this helps some other junkyard modders out.

I researched this cam (trying to see if it would work with the 2004 model, apparently only good up to 2002 models).. lol this camshaft only produces an additional 2hp over stock. =\

Edit: oh damn.. I just saw your other post with the image showing 2-6HP. my bad XD


And thanks OP.

I'm trying to find a camshaft for a N/A setup. As of now I'm favoring the Modern Performance's Crane Street Grind #10 for now. Wish I could find more examples of 2004+ SOHC Neons with aftermarket camshaft. Would make choosing a cam easier haha

Though I've read some great reviews on the Comp 400s

Edit scratch that ^ Apparently the 400s are for R/Ts only (magnum heads). So in this case my next best bet for a 2004 2.0L would be the 200?

Part number: 107-200-8

The NGC computer in the 03-05 Neons really restricts any gains made by any cams bigger than say a Crane 10 or 12. If you wanna go big you need Megasquirt or AEM FIC to control fuel and spark.

Yeah I'm going to look into it.

Would I need MS with the Crane 10?

I don't think so. The crane 10 is about the same as a RT cam or just a bit smaller. You should be able to run a 10 fine or find a RT cam from a member.

I am about to buy an '03-'05 SXT with an automatic. I want to sauce it up a bit, but not at the expense of losing its already weak bottom end torque. Would a Crane 12 be too much cam? Maybe install it advanced 2 degrees or so? I'd find and port/polish a Magnum head and maybe install a short-mid length header if I did the engine work.

The Magnum head might hurt your low end power from the lost velocity in the exhaust ports. Maybe stick with the 12, and a mildly ported stock head. The exhaust ports under the valve can be pretty horrible.

IDK if you are going to see high enough RPM for long enough with an ATX to really make full use of the Magnum's exhaust ports. Granted, the 40te is going to do better than the 31th for DD use.

Also remember, the R/T's had lower gearing to take advantage of those ports.
