T1100 octane light and review

[bcguy]

Okay after 5 days riding these are some things I am finding. When I climb hills and are really on it the octane light will come on and derate. Running 94 and Tryed booster I don't believe it is octane that's the problem it seems like the hard hits or if the track spins( over revs maybe)that is causing it. Kind of scary as it could let me down when I need it. Any suggestions ? The reverse so far has worked fine but I treat it like its delicate china , it has now stated to reverse beep when starting, sometimes goes away on its own and somtimes I have to push reverse button. Put 3 inch 162 vertical post and slp skis on it , have 38 inch arms at home ready for instal. Coming of 1200 rg twisted m series and got myself in trouble on a short vertical. Just not enough power or track speed. I know not really fair to compare the two but I def need more power in this sled because of weight factor.a new pro polaris stock with 174 3inch made the poke. Love the looks, starting to be able to side hill and control better, really need more power but I l talked to lots of people at revy this weekend and the 250 hp range just isn't working reliably on these sleds. How high can we take them and be reliable? What is working the best? I know what's out there , just want more feedback. Thanks

Two things come to mind. Are you hitting the rev limiter. If you hit the rev limiter enough it can trigger the det sensor and give you octane code. Also where do you get your 94 fuel? If it has ethenol than its not really 94. If your completly stock than 91 without ethenol should be enough to not hit octane code. Something else might be wrong.

go through all your hoses , I had a small hole worn through a hose going to my blow off , got det codes constantly on hard pulls , changed the line , no problem since, I'm running the BD box at 22psi on Chevron 94 , no more det codes

Better check all boost hoses and make sure your battery is fully charged! Back in Dec/Jan somebody posted some similar occurences and it was a weak battery and another was a leaking boost hose. Keep using that reverse and you won't be riding much longer that is until the chain and gears come off of backorder. Check into the big chute turbo exchange thread here and you'll find your 250hp answer. Flatlanders have been boosting these engines really high out east and there really reliable. 220hp is most stock turbo can handle at elevation.

250 hp not reliable on this sled? Hmmm...I'm not sure who told you that, but the 1100 turbo can handle that no doubt, with out race gas and having zero problems. Sounds to me like your not getting all the "ummppp" outta your sled if your not satisfied with it. I'd be looking for loose clamps, holes in boost hoses, etc. Or perhaps like the other guy said, your 94 octane might have something to do with it.

The annoying backup chirp is starting to come on when I start my sled too. Only for a second...but still comes on

 

[Two Creeks]

Had the same issue with the reverse beeper and had the sensor cleaned and then it stopped. Then after another 130 kms my chaincase piled up. Stripped both gears and bent the shift fork. I would definately get it looked at. That was at 1500 kms.

 

[bcguy]

It was chevron 94 fuel I used. The sled is stock so I don't believe it's actually a octane problem. Will check all lines and hoses. Just to be clear I like the sled and happy I bought it just want reliable power. Will check out the big chute thread Keep opinions coming

Just got back from Revy you didn't talk to me! I would have told you something is wrong, stock sled is fine with 92. I was running 21psi all week 92 and 1 gallon of 110. 98 gram weights. Didn't miss a beat just took out 2 clutch rollers and blew off a hose. Check your hoses, clutch and Rpm. Too much rpm will set off the code also.

BCguy,

I was getting the octane warning as well. Put a two gallons of race gas in the tank, warning gone. I am working on adding less but don't worry about pulling a code during a climb.

x3 on checking hoses though mine have not been an issue. I have the EZ Jacker box on mine since new and have not had an issue with a lack of performance (coming off modded m1000). Pulls really hard with great tack speed. I will eventually go up in boost from the EZ Jacker but for the first year I wanted to see how things go before I push it. Putting the vert post on this week followed by 8" ski's.

Good luck.

Did any of you reverse guys get the letter from cat on the reverse? I wouldn't use it -- its a timebomb just waitin -- one misshift and goodbye gears. Just unplug the sensor its by the reverse motor and you'll never hear it again.

Got the letter, but it sure is handy to use the reverse sometimes. It sucks that they tell a guy not to use it after he pays so much $ for a new sled.

The biggest issues for the ProClimb 1100T at altitude is the size of the stock turbo and and the efficiency of the intercooler and the way it is mounted . The stock intercooler is too small and the way it is mounted prevents airflow through it. As you climb in altitude, the small turbo heats up the air as it operates near its limits. The intercooler cannot remove enough heat and the high intake temps cause detonation which then activates the protection maps.

I don't know what the ambient temperature was when you were riding, but I suspect it was warm. Spring conditions will make all of the above worse.

We have seen stock ecu, turbo and intercooler air intake temps of 210 degrees after multiple climbs - crazy hot.

As far as the engine being reliable at 250 hp - drag racing guys make 300hp all day long with this engine with only head studs. The guys in Revy are correct - you cannot make that kind of power at altitude with the stock turbo 210-215 is the maximum.

The Evolution ECU reflash should help you out. Increases the rev limit to 8500 rpm. Adds almost 40hp over stock. Flattens the HP and torque curves so clutching is very easy. Makes over 210hp for about 1000rpm. Boost, timing, fuel and a few other things have been changed that increase power and throttle response. If 215 HP isn't enough, there is the big chute turbo, 250hp on pump gas and 280 on race. Head studs and full 2.5" exhaust are a must.

 

[bcguy]

Thanx for all the input gentlemen. Am getting the head studs installed in morning. Any feedback on the turbo dynamics 4 stage program

 

[JustBoostIt]

elevation tunes

No disrespect to anyone doing ECU reflashes. I personally don't know anyone running one on the hill. The Evolution kit has been in the works almost a year and was designed, tuned, and built for mountain riding. That's where I would put my money. Regardless of what setting I have the boost set at I have never seen more than 21lbs on the guage. The huffer is just maxed out.

 

[bcguy]

So with 21 pounds on your gauge what fuel do you have to run , straight race fuel,50/50 mix.

 

[boondockingm8]

Hahaha wierd how a stock pro 174 3 inch beat it lol finally got it out of ya. But yes mark that is a crazy fun sled thanks again
MD

 

[JustBoostIt]

Ahhhh, it's just like 2005 for me. Everyone all over the Apex cause it's soo heavy (um, yup, know that) that's why I'm adding 160hp to it and taking out 75lbs lol.

These sleds at 270-280 will be even more fun than 310 was on the ol' TApex. Lighter, easier chassis to move around. They will be something to see at 300+. In straight climbing ability I have not see a stock anything stay with this at 210hp regardless of weight. I ride with all of them including pg turbos. At 7000 feet it's usually not that close. BCGuy, when you get it figured out it'll make you smile .

I run straight av as that was what I ran in my TApex for 4 years. It's about 25 cents more a litre than 91 in the mountain town we ride from. Less hassle with mixing and never have to wonder if the fuel was bad or mix wasn't high enough.

 

[bcguy]

Do you think av gas would be enough for 20 plus pounds of boost. My 1200 rg at 12 pounds I ran c 14?the most you can expect from av which is labeled at 101 ll is maybe 104 octane
