Cam Specs, Opinions.....
UPDATE
Thanks to everyone who helped me out on this thread.....
Here is a link to the video of my car on the Dyno with the new cam:
http://youtube.com/watch?v=bJqaIcp0Z0o
________________________________________ ________________
Has anyone run this cam?
I think its a custom grind but.....I need some advice as to how this cam may act.
232/236 595/601 114+4
Two people have told me this is going to give you alot more low end power and really trail off on the top end.
One guy said, it is probably not a good nitrous cam.
Not sure what I need, BUT what I want is
a tough sounding idle, strong pulls from 30 to 140mph.
Drive the car often, but like a rough choppy idle.
I have 2002 Z06 with 150 shot of nx.
LG's, Bullett Cat Back, Intake, Comp Springs,
ANY ADVICE?

With nitrous, you need to decide where you want your best performance, with the nitrous on or off. If you don't pick the right cam, your pumping losses can increase and negate some of your gains. You definitely need to favor the exhaust side unless you are also increasing the exhaust valve size.
I would recommend you get David Vizards book on valve trains and read up, then you can make an educated trade-off in your cam selection as more so than with a NA engine, the trade-off's can be greater.

Thank you very much for the insight.
Thats hard to say, but maybe 70% N/A 30%Nitrous
I dont plan on changing valves.
Ikster.........is that the same cam as this one?

Do you see loss of power at higher speeds?
Do you have a dyno graph for yours?
Tell me how the cam acts like, if you can.
I am anxious to get a cam on, and have been looking alot, but this one happens to be available now, and quick to install, local to me.

JUST the fact that you say you want a "Rough Choppy Idle" tells me that the cam you should get should be on a 112 lsa and the lope separation that you are looking at will not be choppy enough for you! I would recommend the G5X3 on a 112 or 113 LSA for you!!

So the 114+4 is not a choppy idle?
The 112 is the choppy one?
I am still on the fence with the cam in question, only due to the fact,
232/236 595/601 114+4
I love my Car and just want MORE of it!
SO would the cam I am looking at be a baby cam?
Would it NOT be worth the effort to change?
2 of you both said G5X3, so I am opening my eyes to that one as well.
Thanks alot EVERYONE!
I am a car nut, and just want more of a great thing!

Do you run nitrous on the cam?
Did you go from the stock cam to this one?
Are you happy with it?
Would you have shose another one instead?

i just ordered a 232/236 580 580 112+4 that is going to be mated up to some TEA 2.5 ls6 heads. i was orginally going to go with a different cam but brain told me that have done numerous test on the engine dyno and it put out some of the best numbers they had seen. as far as idle is concerned this cam has 10 degrees of overlap, so it will produce a very loppy idle. for a comparison the X3 on a 112 has 14 degrees of overlap. unless you are going to be spraying more than a 200 shot, choose your cam for NA performance not spray. however, there are some great NA cams that do well on the jug. good luck.

Thanks alot for the input.
I am
LOST!I have done alot of research for the mods I had made, and I think the Cam is the toughest one.
UGH.........
All ears guys

I run a full H/C setup with a 230-236 112 +2 XE-R cam. The 112 will give you more lope at idle than a 114 and give you a little more peak HP at a lower peak RPM. The reason to go with a 114 is a smoother idle but you will spin the engine higher. The XE-R grind provides substantial mid-range .
My car actually idles better at 850 rpm than a friends 224 114 cam. The difference is in the speed density tune on my car. The car definitely has that cam lope to it but it certainly doesn't shake the car. I can drive my car in bumper to bumper traffic with the M6/3.90 combination and I have the rev limiter set at 6600.
EST 470 RWHP!

Yes, if I were to change anything, I would have gone with more lift.

With Absolute Speed Stage II 5.3's there's plenty under the curve, and from 6100-6600 the HP is very flat.
The cam idles higher than stock but didn't cause any driveability problems. It even sounds mean for a 114. Here's a clip. http://www.nymcgp.com/members/silver...Face/idle1.wmv

I LIKE IT!
I like the way it sounds, I re-read your cam specs
230/236 .580 on 114 +4
and they are very close to the one I may get.

You say you would have gone with more lift? Tell me why?

The cam you have chosen will have a lot of low end torque and ok high end HP.
When ever you have greater exhaust duration and lift you add low end torque
a few notes I have gathered:
A larger intake lobe will make more power up top
an exhaust bias cam what this means is a MUCH larger profile due to the exhaust lobe being that much larger.
-More exhaust duration on a camshaft will allow the motor to run a smaller intake duration for a given RPM range which improves the TQ at the lower part of that RPM range and the larger exhaust duration will help keep the power on after HP peak.
The more important thing with intake and exhaust durations is how they relate to each other when you combine the lobe areas, valve diameters &
curtain area, and flow of the heads. Then you can come up with a total E/I ratio and match something up to that.
have a read on cams http://ls1tech.com/forums/showthread.php?t=327734
I think the more important is to NOT pick a cam, but ask what you wan your car to do??? then talk to severl tuners or one good tuner you trust and let them pic the cam for you.
Good Luck on your project

face, what lobes are you running and what kind of heads do you have? also, can you give us a list of your bolt ons? you have some very impressive times.

IIRC, the lobes are XR and the heads are absolute speed stage II 5.3's.
Bolts ons for the 11.6, VaraRam, LS6 intake, TPIS headers with dr. gas offroad x pipe(wish I could go back to it from kooks), B&B PRT's, Vette Doctors Tuning, Vette Doctors race prepped tranny, Yank SS4000, 3.73 rear, and CCW drag pack.
