Quick question..
Quick question.. Curious.. What is the difference with the 224 114 and 224 112? Heard alot of positive things with A TR224 cam and will get one soon but what is the number at the end mean? 114 & 112. Any light on that would help. Thanks

Lobe Separation Angle. It refers to the spacing between the intake lobe and exhaust lobe on the camshaft. A 112 lobe separation means the intake and exhaust lobes are 112 degrees apart from each other on the camshaft. In general, with an all-motor setup, there is more high end power with a smaller LSA. Smaller LSA camshafts also tend to have a more aggressive sound, and rough idle.
I would probably post this question in the Internal Engine section for more responses.

As long as the lift numbers are alike, the main difference in the LSA (Lobe Seperation Angle) is that the 112 will lope a little harder than the 114 does. I cannot tell if you'd be using this in an A4 or an M6 setup but the 114 is more "A4 friendly" without a lot of tuning than the 112 is. Both will work well with a good tune, though. Also, the 114 will have a higher RPM power peak than the 112...about 3-4 hundred RPM in the top end and the 112 will make a bit better low end torque. The differences will be slight, but there. All in all, the sticks will react pretty close to one another. Does one sound better than the other? To me, yes. 112, baby!! I love the lope of numerically lower LSA's.
Yea i have an A4 but i want the sound to rumble with the LT's. So im guessing with wich ever cam i get (114/112) it will need tuning anyway. So, i guess the 112 wil be a better cam. On that part do i have to replace any of the head components? Man, i am a newbie when it comes to the engine stuff and all the info will help when it comes down to getting the cam. So, thanks!

Your stock heads will work fine with the TR224 but a stage II head setup will give you considerable more power throughout the powerband. For the valvetrain you need Comp 918 springs, Titanium retainers not needed but recommended and a set of Hardended Pushrods. With that setup you will have a relatively light valvetrain that loves to rev. HTH

Verdad Gallardo So.. Buy some springs, retainers, and hardend push rods. Got it!! Was gonna get the stock heads port and polished? But not to sure how much that will cost? Are the Stage II heads much more?
