Ok. I'am getting ready to purchase a new cam for my car and for awhile I was decided on the CCXE 230/236 112LSA. But after seeing how well people are doing with the 306 and stock heads it makes me want to go that route! Now I do plan on porting my heads so I imagine the 306 would be a better choice, but the only thing that makes me decide against it is the driveability of that cam. My Z is my daily driver (when there is no snow) and I want something that if I need to I can drive through heavy traffic with. Also will the 306 be undriveable on the street with ported heads & intake?

All of you guys with a 306. Whats the driveability like with that cam? When you take off from a stop with a M6 what do you revv it to, to take off? Any cam surge down low and at what rpms? If any of you guys with a 306 could provide detailed info on how the 306 reacts on the street that would be awesome! I'am sure this thread will help many other people on deciding if they want the 306 too! Thanx for the help!

 

personal opinion-
the Xe works better with opened up heads
306 stock heads due to its longer durration on exhuast. (our exhuast ports suck )

this is what i've noticed anyway

 

Mine opinion of the 306 is that it is a great cam, however I have a 383 which helps with the drivability. With 4.10 gearing your car would prolly have better manners than mine does now with the stock gears (3.42). It is very streetable in my car, I can barely tell a difference between it and my hotcam.......until WOT.

As for taking off in the 383, I rev it the same as I did my hotcam, about to 1300-1500 and it takes off no problem. I imagine with stock gears in a 350 you would prolly want to hit close to 2k or so, I really wouldn't know though, others can chime in here.

The 306 is so good with stock heads because of the long exhaust duration, but even some worked exhaust ports aren't that great.

 

Check out my sig. I think the 306 is perfectly streetable. No surge at all when taking off from a stop. It lopes like an sob though. It does take me a minute or two of warming up the car before I take off or it will die (tuning was done by pcm4less, but still have some minor issues). The sound of that cam, especially with heads and lt is f--king awesome. It will terrify children, set off car alarms, and eventually cause you to become sterile I love it.

 

Its streetable,but gas millage and cam surge is the worst of it,wish id go a bit bigger though!

 

I have the 306 and love it. I do have an a4 with a 3400 and 3.73's. This is my daily driver. It does surge just a little but not enough that i dont mind. I would recommend the 306.

 

Now Iam leaning towards the 306 instead of the 230/236! Anyone else out there with a M6, CC306, and stock 3:42's. What do you revv it to take off at? Where does the cam surge at down low in the rpms? Sorry for all the ?'s its just that I don't want something that will be a pain the *** to drive! Of course I will be changing gears to either 3:73 or 4:10s in the future.

*EDIT*
Also, I was wondering how the car will act on the hwy at 60-70MPH revving 1500-1700rpm. Will it pull very well in 6th that low in the rpms? Or will it stumble and not want to drive?

 

Geesh! I just can't make up my mind. Now instead of the CC306 and XE 230/236 I was thinking of getting a custom ground cam. Something like XE 232/238 on 112LSA. I want something a littlebit bigger than the 230/236 but I also want something with some midrange unlike the 306. Since the XE grinds are supposed to respond better to ported heads I think that would be a wise choice. What do you guys think? XE 232/238 112LSA? Lets hear some opinions!

 

we just put a 230/236 in my buddys a4 Z on stock heads with bigger valves, the car pulls hard. the loss of low end torqe is not even noticable.

but im like you i have the heads just about done the cam is my problem, i want something a little bigger than 230/236 but i want mine on a 110.

i think custom ground cams cost a little more though. does anyone no for sure

 

Yea they do cost a little bit more I'm sure but its not enough for me to look past it. I look at it this way. Buy an off the shelf cam and be satisfied with the results or maybe wanting a little bit more, or just pay the little bit extra and get a custom grind and never look back!

 

I think the 306 has plenty of mid range. I don't know how it's highway manners are on an M6 since I have an A4, but I noticed it does have some surging.

 

combomotorsports has a GP for $217

 

So what difference does a lower LSA make. Does it give it more bottom end or something?

 

lower lobe sep is good for NA, mean *** idle, and moves the powerband up..

 

i just got my 306 in from combomotorsports on the GP ground on a 114 LSA as opposed to the standard 112, upon recommendation from Comp Cams. I'm no pro on the specifics of cams but they said it helps on the exhaust side of things for a N2O motor, and I plan on spraying the hell out of this thing. Combomotorsports also has the best deal going on these CC kits. I got the cam,1.6 CC rollers,seats, seals,valve springs,gaskets and a Cloyes double roller for around 650 or so.
