Seems like most "stage 1" turbo kits double the stock HP... I wonder if the same will be true for the Maverick???

the specs I saw said that the engine has 12:1 compression ratio... way too high for a pump gas turbo system I would think.

It will be interesting to see what the turbo kit builders come up with for options.

Might get 150hp on E-85 @ 6psi or so with stock pistons..... ??

But with 8:1 pistons I'm thinking 180hp @ 10psi & 200ish @ 12psi .... Thoughts anyone ??

someone posted that the stock engine has closed loop fuel system, knock sensors, and two O2 sensors.

I read it has a cat converter too............smog legal SXS? WTH? Maybe you can get another 10+HP by changing the exhaust..

 

[Tuf-Skin]

10 HP increase isn't enough.... :big smile:

Haha I love the sand drags. Last trip a bunch of us were blasting down the strip on quads and I thought my 700XX was pretty quick, just then one of those turbo RZR XPs blew by me like I was standing still. He had to be pushing 90+. Impresive for sure

What's the max hp a prostar 900 can handle ? Right now Mrrpms turbo
rotax with stock crank and block with aftermarket rods and pistons is pushing 400 hp.

 

[Canamxteam]

So 150 hp should be pretty reliable

A buck fidy should be a good no. if the drive train can handle it?

Yeah while very much impressive, thats a drag racing setup and I dont think it has ever been run longer than a dyno pull, or drag strip pass. Ask Greg about cooling and he'll say, "hell, I aint ever run it long enough to get it hot" lol

You can run forced induction on a 12:1 engine all day with the right fuel or water/meth injection and cooling system. If the system is a closed loop with knock sensors, that will be the biggest hurdle in making power. I run a 13:1 975cc Rotax and with anything less than 100 octane, it knocks.

 

[Canamxteam]

What kind of rwhp is your 975cc putting out

 

[Brian B]

mid 70's. We have to run them inverted, so we lose a couple extra to the driveline because the power is going through the tranny and back through the through shaft.....

My Turbo 900 xp motor is all stock...just upgraded injectors and tuning for the Turbo!...I have a couple hundred miles on this setup so far and no issues with cooling at all!......Gets to 60mph in 4.5 seconds in full weight trim....

 

[Canamxteam]

Looks good what psi you running

 

[Canamxteam]

my slow commander

This is with a small ebay turbo with only me tuning with a pim2 Had only 500 miles and the oil seal in the turbo let go Im putting a oem td04 turbo on now set at 7 psi should run alot better
