what are the pros and cons of each cam,,,also how does the 224/230 compare to the 230/236 and the cc306?

 

the 224/230 is VERY mild for most people and it will have the drivability and sound of a Hot Cam or CC305 and make about the same HP or maybe 5-10 more HP. It will work with ANY gear, stock converter, probably pass emissions with good tuning, etc. Very good mild/street cam but most people end up wanting something a lil bigger. It will pull hard down low and make power to about 6000-6200 RPM. stock injectors, TB, etc will brobably not be a huge restriction with this cam but with ported heads, better injectors and TB would help.


the 230/236 will make power to about 6400 RPM. It will have a rougher idle than the 224/230 and probably not pass emissions unless you are a bad *** tuner. An A4 with a stall and a 3.42 (or better) rear gear will make this work fine. Larger injectors and TB are pretty much mandatory for best results.

The cc306 has a duration at .050 of 230/244, even though these #'s are close to the 230/236, they are more different than these #'s show. The cc306 has a slower ramp and has a higher "seat to seat" timing that is a lil easier on valve springs but also allows the cam to pull to a higher RPM than the 230/236. This is a good NOS cam and is a proven performer. Seemed to be the "standard HP making cam" before the XE lobes came out.

The 230/236 will probably make a lil more power below 2500 RPM. From 3000 to 5500 RPM, they will probably make the same HP and above 6000 RPM, the cc 306 will probably make a lil more HP. The XE lobes seem to drop off pretty quick after their peak so if you intend on shifting above 6500 RPM and can afford to lose a lil power below 2500 RPM, go with the cc 306 out of these 3 cams.

It is not only the amount of HP that each cam makes, it is more about what RPM they make it at and what RPM they do not make it at. Driving style, rear gear, stall size, complimenting mods, emissions?, maximum RPM you want power, minimum RPM you need power, etc. are gonna determine what cam would be better for you. There is not 1 cam that is best for everyone.

Let us know how high you wanna rev, if you need emissions, and if you want to sacrifice some top end power for low end torque or vice versa. Also are you porting the heads as well? For what it's worth I'm very happy with my 224/230 but NightTrain66's ported heads probably have alot to do with that.

224/230 is about the same as the HotCam? what would the gains and losses with hotcam over the 224/230 and what would be the price diffrence /on a bolt on car A4 (no stall) with no emmissons

 

I personally think the 224/230 completely out does the Hotcam. it's not that much bigger, but the ramps on the lobes help make a F-L-A-T Torque curve. Plus, it's gonna make a bit more HP than the hotcam, with and without heads.

The 224/230 is awesome. No driveability issues, good idle, no vaccuum problems or anything of the like.

 

NightTrann66 hit it right on. Love the heads btw.
I like the xe224/230 in my A4. It seems though most of the M6 guys go with the XE230/236. My car is a vert and not so much a drag every weekend car more than a weekend street cruiser. The 224 is great for that. All I can really say for sures is numerically lower gears will really hurt this cams low end. I had 2.73 and went to 3.42 in my A4. I should of done 3.73. I wouldn't to a 230 cam in a M6 without having 3.73 or 4.10 gears IMO.

i probably won't want to rev any higher than 62 or 6300 rpms, but i want a cam bigger than the lt4 hotcam,and sounds like i want bigger then the 224/230 also. i'm most likely going to port my heads. i need the car as an everyday driver, but i don't mind it loping alot. are you guys saying that the only time i'll see "more power" w/ the 306 is above 6200 rpms? if so , that wouldn't be good for me. the 230/236 would have more power than the 224/230 midrange, or just past 6200 rpms?
once i have 1 of these cams picked out im getting one, but i can't make my damn mind up!

thanks guys for your help

I have the 230/236 and Lloyd's heads. I would not hesitate to drive the car everyday in stop and go traffic (although it's not my daily driver). With the dyno tune that I have, it drives pretty much like stock at low RPM.

I have had it with the stock 3.42 rear end for about 6 months. It's not really a problem, but I have the 4.10s sitting at home waiting to get installed.

The only problem is traction. First gear is nearly useless, and second slips a lot. I have gotten sideways at 45 just mashing the gas. My only trip to the track was disappointing because I was spinning halfway down the track. I made almost the same MPH using first only until 2500 rpm.

 

I was curious how the 227/233 might fit in here and if anyone's tried it yet?

 

Thats exactly what I was gonna post Impy. I really wish I could drive all your cars to feel the difference in these cams. Theres not enough car people around me (that I know of). The 224/230 sounds like the perfect cam really, but I just am so afraid of going too small...

 

I love my 224/230 so far, it is a great cam for driveability. It still makes great power too both with stock heads and with ported heads. The problem with it though is that it really makes me wonder what the 230/236 feels like...

 

I have the 230/236 and well I love it but I am greedy and am going to something bigger like a 236/242. the 230/236 is in mt daily driver and it great and pulls hard from shift point to shift point set at 6300. If you want to know what it fells like go spray a 100 shot from 2500 rpms to redline and that is about what it feels like.

 

ok, the 230/236, does it have alot of cam surge or anything, i have an m6 and it is a daily driver, all of this stuff is of concern to me

 

The 224/230 is what I went with, recommended by Combination Motorsports for my specification. When I step up to a 383, I'm sure I'll go with something bigger, maybe a 230/236 XE grind. I guess the XE grinds allow a bit more airflow into the chambers @ low rpm which gives you that torque down low, which is what I will need for road racing.

The thing with the 224/230, it feels stock down low, if not a little more punch to it, but after that it just keeps pulling harder and harder all the way to redline. Great cam!

 

is there much of a drivability difference between the 230/236 and the 306 for a m6 daily driver in a 383?
