Quick question with bigger cams and LSA...
Quick question with bigger cams and LSA... I am very interested in the MS3. The only thing that is pushing me away is that it will not make power untill later. So my question is, if you got a custom cam of the same grind and just made the LSA like 115 or 116, wouldnt that move the power band down a little into a more useful range. I could be way off but I was just wondering this. Thanks!!

HAHA ok I knew that seemed a little awkward when I wrote it. Thanks for the clear up. So, theorhectically, could that work? Could I have a custom ground cam the same as the MS3 but lower the LSA so they power is down low?

so...basically, if he wants more power under the curve, i would suggest a 114/115 lsa.
110 = sharper curve
115 = lazy curve (if you can picture those..) it makes sense when you actually look at 2 dynos of similar duration cams on different lsas.
also, the amount of advance/retard ground into the cam plays a role in its powercurve generation. adding advance will flatten the curve, but push the peak up a bit. retarding does the opposite..
For being the big cam that the MS3 is, it does have good driveability. We have many customers that use this cam in their daily driver and have no problems, even A4 cars. With a big enough converter (if A4) and say 3.73 gear this cam will give you good driveability and great power with stock heads, nitrous, aftermarket heads...etc. If you need some pricing or any other questions you need to ask, feel free to pm me or give me a call!!

Verdad Gallardo Ok so It could work if thought out and planned correctly. Zach...I will be contacting you guys in a couple months to get the MS3.PRC Dual kit once I can gather the funds.
The MS3 does have great drivability for how big it is and I have an M6 with 4.10's so drivability is not going to be an issue with me.
