UPDATE:

I just wanted to thank you guys again for the advice and let ya'all know how things went for me.

I installed the 14mm rotor and was able to gear right back up to a 16 pinion without issue. Temp seems to max out at about 150 no matter what pinion I use with the rotor. So far I have tried the 12, 14, and 16. I still have a 17 to try out but I don't think I really need to try and race with it. With the sixteen I was able to clear the triple at the track right along with the nitro's. Way better than what I was getting from the 12 pin!

Just a word of advice for anyone who upgrades an older novak with a new rotor. These thing are the most powerfull magnets (lb for lb) that I have ever messed with. It is real easy to lay it down while your working and get metal slivers or flakes or whatever happens to be in the vicinity stuck all over it! lol And when you put it in the can you need to have a death grip on both the can and the rotor because the magnetic force will slam the two together before you have time to react and stop it from happening. In my case I was lucky because the 14mm rotor is so big that it can really only go in almost perfectly straight. This is very important because there is circiutry at the bottom of the can that can be easily damaged if the back rotor shaft smacks into it. Novak try's to explain this to you in the instructions but they don't quite prepare you for how hard the rotor slams into the can if you lose your grip on it. Heck it's hard to keep them from smacking even if you do have a good grip on it! The instructions said to insert the plastic tube that the rotor came in into the can to help guide it into the can but the tube didin't fit in my motor. Still scratchin my head on that one?

Anyway, thanks again and hopefully this will help others out that find themselves in the same situation.
