Question xe 218/224

I have all parts except the headers. Here is the rundown:

218/224 dur, .528/.536 lift
comp 1.6 3/8" self aligning rocker
Isky 235-D Springs to .550
comp titanium retainers
comp 10deg locks
meziere wp
Ed Wright - fastchip tune (haven't sent it yet)

Heads - Local Machine Shop
Bowl work and port match
2.02/1.60
11:1

I drive the car everyday on the street. Hit the track maybe 5-10 times per season. I decided on this setup a long time ago for reliability purposes and have been accumulating the parts ever since. Now I'm starting to question if this setup is too mild. After reading all the posts for the xe224/230, I'm thinking about changing it. But then i have to change my spring setup. What do you guys think for a daily driver

I think thats a good setup honestly. All depends on how deep your pockets are.

I am going from a 236/242 to a 224/230.

What lope seperation?
auto? manual?

Same cam I was initially going to go with (or the hotcam) but decided to bump up a bit to the 224/230 112 (1.6 non-s/a pro mags).

VERY happy with this cam on a daily driver and it's been about a year so far. I also have an A4 with the stock converter (until Sept or so) and heads.

Those Isky's will handle the 224/230 if you decide to switch to it, btw. The lift will be about 537/544. I assume you got them from Thunder? Give 'em a call and verify, but I'm pretty sure they'll be fine with it.

From what i've been bouncing back and forth and learning recently- (assuming this is an NA car)

go with a 110 or 108 LSA (repending on idle quality)

6speeds have closer gearings and appreciate flatter bands (produced by more overlap) less than autos. 6 speeds run faster with more peak power because they can keep slamming gears and staying in the area of that peak,

224/230 110

I see a lot of people comparing the xe 218/224 to the hot cam because of similiar .050 specs but they are very different cams. I did the same as you because I like the idea of streetability. The 224/230 is really getting close to the line of streetability in my opinion although I still think it is a good street cam. I can tell you that it is only worth an additional 15 to 20hp on the top end. From seeing other peoples dyno #'s But with good heads long tubes & some tuning 360 to 370 rwhp is easily had with the 218/224. Very respectable for a street car and it still has gobs of bottom end even around 1500rpm. Also as far as lobe center goes 112 is fine and actually seems to work the best for most streetable LT1 combinations I have seen. In other words I think you have a good plan stick with it!

This is true, I didn't mean to imply that the hotcam and the 218/224 were interchangeable, just that those were two I was considering.

As for the 224/230 being close to the line of driveability, I have to disagree with that one - it's no problem at all. I've got no vacuum issues and with the idle set to 850, it's not as smooth as a stocker, obviously, but it's not even close to being hard to live with.

This is just my experience with it though. There are plenty of others out there with this cam and drive with it daily. I'd do some searches and see what they've got to say about it.

As y'all can see from my sig, I have the cam you're talking about. Jkipp84, I'm curious as to how much vacuum you have at idle with your cam; since it's a step up from mine. I have 15.5-16.0 psi at an 800rpm idle (stock); my vacuum with the stock cam was 21psi. I have no other basis for comparison, but I REALLY like my cam . You can definitely tell there's something different under the hood - Mmmm....Mmmm....sure has a nice chop to it; also there's definitely cam surge, but not that much. No dyno/dragstrip #s yet, but let's put it this way.... Before my cam/heads, I could hook the car up from a 2000rpm roll in first gear, and would chirp 2nd gear. Now, I don't hook up until about halfway into 3RD GEAR! That and I still get over 27mpg on the highway with a stock tune. If your car spends much more time on the street than strip, I think you'd be really happy with the CC502.

Thumbs up

Thanks for all the info guys, you've been really helpful. I think I'm gonna stick with my setup and build for reliability. If I went to the 224/230, I'd be pushing those springs too close to the limit. And it's a completely stock bottom end with 95000 miles. I'll let you know the #'s when it's done!

check out cam in sig. great for daily driver, no codes and runs great on the generic hypertech tune. strangely enough, a dynotune showed no improvement over the hypertech. cam has been on the car for 8 months and no problems at all. you should be fine with your cam also.

I've been exceptionally please with the recent install of the CC502 (218/224) cam. (I had the Crane 210/224, which is also a good daily driver cam.) You want a fat, flat TQ curve for a driver and this cam seems to deliver. Smaller cams perform well on a daily driver.
