More power from ZRT 600 -98?

Bearcat · Apr 19, 2010

I'd like to get more power out from stock ZRT 600 -98. What things works with these? Noticed it needs case porting at least.

How about other known mods? What have you done to yours?

A set of after market pipes r usually good for about 15 HP. I have three ZRT's and have PSI's on my 96, D&D's on a 00 and Aaen's on my 700 mod sled. I think a set of PSI's would work best on your 98. They really work well on the old 96. Maybe advance the timing a couple of degrees with a keyway. Good Luck!

most aftermarket corps that made cat stuff back then sold extra fat base gaskets and then you would shave the head it would change the porting timing then add a timing key to make them great lake race sleds .I would bet D&D would have some shim kits lying around or know who did.$1 for $1 was the most power for the 600zrt add the pipes and v force I was taking stock zrt800s all day I think peek was at 9000 and on the dyno only lost like 2hp revving out to 9350rpm.but that is all relative if I remember I think it dyno at like 135hp but that was big in the day with a 600.at the same time I had a zr700 with black magic twin pipes and that only made 132 and the zrt would kill it every time no matter how much time I spent with gearing and clutching.I still love the power band of a well set up triple lucky for me I have buds still running heavy mod thunders so I get my 3cly fix a few runs a season

Thanks. This sounds really good.
Can you remember how thick was the base gasket? I mean would it be the same if I just put two stock basegaskets?

Yes u can stack the stock base gaskets. I think it was three of them but cant remember for sure. I will ask my son if he remembers how many to stack. Black Magic made a shim kit at one time, but they r no longer with us. I dont know if D&D ever made one, but u could try contacting them.

This will be cheap and light weight DIY watercross sled so I'd rather do as much as possible by myself

if you want a lot more power put a 700 big bore kit on it they run real well

That would be good thing to do if I'd use this at winter

But there are class limitations in watercross so it must be below 600cc.
