MTI C2 or X1, help me choose! How driveable is the MTI X1 cam? I was considering the C2 but have been hearing good things about the X1 and now I don't know which...
It's imperative that the car still be driveable car around town.
Car is a 2002, LS1 M6 with the usual bolt-ons, HPIII programming and FLP Longtubes.

Re: MTI C2 or X1, help me choose! I have a 382 , auto, with the X1 cam and I wish I went bigger! I have a Vig 2800 stall and 3.23 and it is perfectly drivable. No surging, dying, or lugging. With the cut out open it sounds mean, but with it closed and the stock SS rear exhaust it sounds nice and quiet (kind of mechanical sounding though). In a 346, I imagine it would be a little rougher, but not too much. Mine was on a 114 lobe also since it is an auto. Definatley not too much cam, these newer computers can handle alot of cam, that is what I am finding out (compared to late 80's early 90's computer controlled vehicles where a 219/560 cam was big).

Re: MTI C2 or X1, help me choose! What are your future plans for the car, and how much track time does it see?
I would think there would not be more than 20 RWHP difference between these two cams (all up high in the RPM Range). On stock heads you are probably only looking at 10 RWHP more from the X1 over the C2, maybe less.

Re: MTI C2 or X1, help me choose! For a daily-driver, I'd still prefer the C2 cam. For a weekend toy, I'd go X1 all the way. Make no mistake, a 224/224 cam still lopes pretty damn good.

Re: MTI C2 or X1, help me choose! I have had both. I would vote for the C2 in a heart beat.
It makes killer power at a livable RPM. The X1 is a bog cam and if you were to get all out of it that it had to offer... you would have to spin your motor very high.
I run my X1 over 7000 rpm's.
The C2 will make good power and if you shift at 6700 you would be in the meat of the power band. (in general)
ALWAYS go smaller than you think you should.
Good luck.

Re: MTI C2 or X1, help me choose! I made the exact same decision recently; in fact, as I write this my car is at MTI getting the X1 installed! I pick it up tomorrow and will give you my impressions on driveability, etc. This will be my first cammed car, and its my daily driver so hopefully I can provide a good frame of reference for you.
Re: MTI C2 or X1, help me choose! X1 Running hard
X1 Idle
my dyno is in my signature....
obviously I vote X1
just be sure to get the Manley springs/titanium retainers/hardened pushrods package that MTI recommends with it.
and with slicks it it not a bog cam.....
you can pull the front end up if you drop it at 4000
streets...definately 3000 and feather it out....or bog it at 2000 with good street tires..
I'm in the 12's
very well mannered on the street...my daily driver....and just push the foot down for fun....
I shift at 6500...and rev limit is 6800

Re: MTI C2 or X1, help me choose! I'd take the C2 for a daily driver unless we're talking about using 4.30+ gears in a weekend toy. If that's really the case then I might take the X1 if I wanted it to sound as fast as it is.
The C2's power will be easier to use on the street.

Re: MTI C2 or X1, help me choose! Just got my car back today from MTI with the X1. I had a 150 mile drive back to Austin so I was able to get a good feel for its manners and how driveable it is.
Let me say, no problems whatsoever. It finds idle (set at 850) within seconds and did not die on me once over nearly 3 hours of driving. Likewise for when I cranked on the A/C. At cruise I barely realize its not the stock cam... until I hammer it. Its definitely a HP cam, seat of the pants meter doesn't register much difference until around 3000, but whoa after that until 6500! The car is all over the place through first, second, and into third.
I'm definitely glad I went big. More midrange torque will probably make my traction issues even worse...
