Hi guys. I'd like to get a aftermarket CDI for my 2004 Rhino 660. I am looking into Hunterworks Tri-Fire or the MSD Charge. Which one do you all suggest and why? My rhino is stock right now, but I just ordered Rutting Rhino's jet kit. I'm not looking to race my rhino, just looking for a little better overall performance. Thanks

The main advantage of the Hunterworks over the MSD is the timing advancement. The hunterworks is also double the cost of the MSD. If I was to get a CDI box with the timing advancement I would go with the Dynatek which offers a life time warranty over a 1 year warranty as it is comparable pricing to the Hunterworks.

From my research, the Hunterworks is only $50 more than the MSD Charge. I have heard that the Huterworks can start the rhino better in the cold than the stock CDI and the MSD Charge. Can anybody confirm this?

A MSD Charge pt# 4240 for the Rhino 660 does have timing advance in it. I believe it is 4 or 5 degrees of linear increase. If advanced timing and increased rev-limit are what you are looking for then bang for your buck the MSD is the best deal. If you plan to do additional mods down the road I would recommend MSD pt# 4217 Single cylinder Programmable CDI and a 42171 harness to match for the Rhino.

The better starting when very cold out is due to Hunterworks Tri Fire being a true multispark ignition.

The easier cold starting that is supposed to come with the Tri-Fire, is the main reason that I am looking at the Hunterworks. I plan on plowing with my rhino, and being from upstate NY, it would be nice to have the rhino start up a little better in the cold.

Does anyone have the Hunterworks Tri-Fire CDI and also lives in a cold area that can tell me how their rhino does in the cold?

I run the Tri Fire on my 06'. Had a ProComm and the cold starting was a bit$h!!!

Put the TriFire on it 2 years ago, and I am very pleased with its' performance. It fires up RIGHT NOW when cold. I like the ability of the "valet switch" that limits top speed when the kiddies drive it around.

FWIW. C-Ya!!

From my experience the Tri Fire on my old 08 450 helped it start easier in 0 degree weather. The "Brother-N-Law switch is nice for relatives who want to drive it and you can limit them some. I gained a couple of mph also with the rev limited raised. It was personally one of the best modes I bought for my 08 450. I now have a 2011 700 and with the tri fire on the 08 450 starts almost as easy as my 700 does. I have never used the MSD charge so I can not compare them. I will be looking to get the MSD for the 700 sooner or later though.

Well, it seems as of right now, I am leaning towards the MSD. I don't think that the "brother in law" switch, and the reverse rev limiter delete of the Hunterworks are really that important to me. As for the tri-fire of the Hunterworks, I might just throw in a iridium plug with the MSD and hope that will be a little better.

Considering MSD is an acronym for " Multiple Spark Discharge" I would assume that is was multi spark also.
From my drag racing past, MSD actually fires 6 times per spark, I've seen it on an ociliscope. Does this not hold true in the ATV products?

You know what they say when you assume, hahaha!!!! j/k. I have no experience with the MSD unit for the 660, but the MSD FI Charge for the 700, is not multi spark.
