In Codex: CSM you have to be very careful about your lists, each part must contribute to the whole. The key is synergy, redundancy, and knowing which upgrades to take on which units and which ones not to take.
Some problems with your list:
1) You're running your terminators like SS/TH loyalist terminators, but no matter how much makeup you put on a pig, its not a girlfriend, still just a pig. I wouldn't take terminators unless you're an experienced CSM player and have some games under your belt, and you have a specific task for them. For instance, after I get some more games done, I think I'll put Ahriman in a squad of 5 Tzeentch Terminators with flamers and axes, because he has a lot of 12"/template witchfires, but he doesnt want to get into CC, so the terminators serve as meatshields from shooting, and serve to deter charges with powerful CC and overwatch abilities.
2) Going back to what I said about upgrades earlier, CSM are one of the units best taken with almost no upgrades. Give em 2X the same special weapon and a rhino and they're good. If you really want to trick out the champion, it should only be because the squad has flamers/melta and might end up in CC. If that is the case, you will want to give him a LC or P. Sword. Use that I4! P. axes and P. fists are reserved for Plague Marines (who attack last often anyway) or terminators (who are durable enough to attack last)
3) Don't mix weapons on havocs. Unlike Longfangs from the SW Codex, they cannot splitfire. If you're looking for versatility, take oblits. If you have a task in mind and you want the highest DPS, take havocs with 4X the same weapon
4) You replaced your MMs on your Helbrutes with P fists, why? Helbrutes simply cannot be equipped for CC. They have no method for getting into CC and once they get there they are rather unintimidating with 3 or 4 Str 10 AP 2 attacks that many other melee units have or can beat and they only have 1 or 2 HP left at that point anyway

If I were to make a Daemon Engine List, it would look like this:

Look how much armor saturation we have! Your goal will be to eliminate all Anti-armor your foe has, then wipe the board. Keep your troops somewhat safe and grab stuff late game. This list has 55 pts to spare btw]]> http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6640250.page http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6640250.page GMT OP.

I figured the Brutes would lower the WS of the enemy by 2d3 with 2 P. Scourges. Along with the defiler to smash up stuff after using it's along the way, then the Warpsmith could repair.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6640286.page http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6640286.page GMT ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6657455.page http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6657455.page GMT http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6657667.page http://www.dakkadakka.com/dakkaforum/posts/preList/585215/6657667.page GMT
