MTI C1 CAM VS MTI C2? Which cam would be best for an Automatic car on stock cylinder heads?
Which would be better for an Automatic car with Ported Cylinder Heads?
Car is driven on street, but is only race in the 1/4 mile.
Thanks In advance

Re: MTI C1 CAM VS MTI C2? I cant say which is better , but I have the c1 and it pulls very good . The power is in a very usefull curve . peak tq at 4200 rpms( stock dyno peaked at 4400 rpms) and hp peaked at 6000 rpms at 389 hp and was still makeing over 380 at 6700 rpms and 375 at 6900 rpms. at the time of the dyno I only had 1,000miles on the new engine and was not broken in all the way. I have very little done to my heads other than the 2.02 valves and mild bowl work. nothing in the runners. My car is heavy ,3682 with me in it and I am useing mac headers and oryp . I did not have a ported t/b then and I still do not have asp pully. I have ran a best of 11.75 at 118.39 on Nittos and A new best mph of 119.35 in full weight through a cut out.

Re: MTI C1 CAM VS MTI C2? Same question worded differently...What's better, $1.00 or $.99? <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
There's not much difference.

Re: MTI C1 CAM VS MTI C2? Think of it like this"
C1 will tend to make a little less hp, but be easier on the valve train.
C2 will tend to make more power because it has more lift and duration and be harder on the valve train.
My SRP224 is very similar to the C2 and drives fine with MTI tuning. Ported heads are always good. Get dual springs and you'll have less issues out of either cam.

Re: MTI C1 CAM VS MTI C2? i say use the c1.i have it with heads and all the goodies. peak hp 424.1 at 6,400rpm's dont stare to drop till 6,750rpm's. peak tq 407.4 at 4,800rpm's, and thats with a 12bolt costing me some power. the c1 is not too lumpy,drives great around town and delivers the power when needed. my m6 ride pulled 11.71 at 118.6 spinning most of first. goodluck to ya.

Re: MTI C1 CAM VS MTI C2? If your doing heads, I would definately get the duals. If your staying with stock heads the 918's seem to work ok for the most part. Personally, I think the 918 is a single spring trying to do the job of a dual spring. The REV-1116 is a dual spring that will work with stock heads without machine work. The REV-1116 haven't been out that long so their isn't a lot of feedback on them. Someone had a Rev dual break. Sometimes the 918's break too. Very seldom do the dual's like the Comp 987's break even with agressive cams like XE-R's.

It's always best to check, but if my car was ok I think your car would be with stock heads as my had ported heads. If your getting ported heads talk with the porter but seldom (if ever) does any see serious P to V issues with a 224 sized cam unless the heads are milled a LOT.
