Riding the 975 Turbo
- Thread starter Z-Man
- Start date
got everything torn off the front of the engine fixing all the minor issues right now. Have to put a couple helicoils in the bolt holes that hold the exhaust valves on. Hope to have her up and running by the weekend. Third times a charm, I hope.

Watching you ride it I am wishing I still owned it! It is a one of a kind. I hope you get the bugs worked out and enjoy the he!! Out of it!
Got the helicoils at Napa. Going to try to get her all buttoned back up tomorrow. Thing is going to be sick when it puts out full power. Hopefully my work finishing it up can do justice to what you created.
Oh, forgot to mention I talked to the guys at HM turbos and they said they had built a few 975's that weren't turboed and they were crazy...lol
Well she ran beautiful only one problem. The seal between the mag side piston and the center chamber is bad so she blows oil out around the oil pump.
Going to be pulling the 975 out this week and sending it to IndyDan to either be repaired or to get upgraded to a TM1.
Just called Dereck Fischer and he is building a set of 10:1 compression domes for my other 900 TM3. I should have it up and running by next week with as a pump gas turbo 900 TM3. So now it's going to be a PolCat 900 turbo. Polaris 900 with Arctic Cat Primary clutch and Diamond drive secondary.

Kinda sad to see something so beautiful tore apart...
What is TPO hood?
It's getting a new updated crank kit because it had a bad seal.
TPO is a flexible plastic like new car bumpers are made of.
What Elevation are you riding at? What clutching do you have in yours?
I just did the TM3 with an attitude turbo and pretty close but wanting to see what combos others are running. only had it out 3 times and wow it is incredible how much power they have once you get all the bugs out.

I got the engine in and started it up and it was leaking antifreeze from the head studs. When I tried to seal them one of the studs pulled out so I had to take the engine back apart. I sent the cylinder and clutch off to IndyDan, hopefully I will have them back this week. I did manage to get the new hood installed though.
