Cooling down the intake temps when warm out - hot!

[AnythingButLast]

Also remember that the intercooler on your apex is likely mounted directly to your throttle bodies dual purposing as the "airbox" on the throttle bodies vs the sidewinder having a dedicated box and runners into the throttle bodies from the intercooler. You don't have a "cool" side charge tube just the cool side of the intercooler into the throttle bodies making that end of the intercooler larger for volume.

If you have high octane fuel does it make eng run hotter, I add in Torco sometimes, 270 race 91 Octane +?

No. If anything higher octane makes the engine run cooler as it delays and slows the flame front. A bit like less timing where the heat is removed from the engine and makes the exhaust gases hotter out the pipe.

Don't see much talk about the high intake temps when its warm out like up in the 30's F. Just though I'd start a conversation about it as just got a text from my bud who was riding today up in Northern WI. Temps in the high 30's and he's seeing intake temps way up in the 90's when getting on it. Keep in mind this is a bone stock machine and no plugging of the intercooler with snow.

He's seeing RPM up at 8950 and 9000 range, when intake temps get up into the 90's, the R's fall right off to 86-8500 and sled slows or hits a wall. Seen the same thing last week up in the UP with mine and the 240 or 270 tune in it when temps were up in the high 30's last week. In the single digits not nearly that high. Sustains power much longer when colder out. Temp rise when warmer is much greater than when cold out. Rise when warm is aobut 60-70 degrees, when cold maybe 40-50 degree rise on a pull. ??? What are others seeing? Don't know how anyone could run hard in the deep snow with it like this. Maybe cooling with snow would be better to a point.

I don't know if air isn't getting thru the intercooler because pressure builds behind it at higher speeds, or if things are just getting that hot and can not be controlled with the stock intercooler. It would sure seem you'd get a ton of cooling air thru there at high speeds, but without work in the wind tunnel, perhaps there is not good flow thru there. Things heat up very fast in the intake whether stock or tuned either way.

Very disappointing that temps can't be held down better than this as it really limits power and RPM when warm out. Seems temps need to be in the single digits F. to stay in check properly.

If the air cant get thru the intercooler at speed, you'd think a fan could help out there. Or is the stock intercooler just not enough?

I hate to think about putting Meth injection on, but maybe that's what it will take. Not sure a bigger intercooler will do it if there's no airflow thru it either.

Anyone running a bigger intercooler yet with info that would verify it even works?

How do you read the intake temps on a stock sled or do you need a tune for that option

Factory gauge has the intake temp on lower left. You can also set it to read in degrees with the temp number there.

Anything new, it’s warming up this time of year and again we’re losing rpm with hot intake temps,

I still have hot intake temps on the big tunes when warm out. Put HUGE full size hole behind intercooler too and frogskin over it, and didn't help much if any.

Lots of larger intercoolers out there and secondary intercoolers, yet we really hear nothing about them from actual users. I don't think they do much from the sounds of it. Need more than 10-20 lousy degrees of help for the cost of them. MCX looks to have a nice HUGE intercooler but they didn't e-mail me back.

I spoke to several companies about the situation and nobody seems to have a solution. A intercooler doesn’t do much for trail riders, to bad we couldn’t move the intake to the other side by the turbo like on the 1100s . To bad we couldn’t get rid of the intake crossing the engine from one side to other.

Went out yesterday 45f and sunny. Just to maintain trail speeds at 85-90 mph IATS were at 91f. Wow...hot!

I too have been looking into this and it looks like Tommcat Performance might have the best bang for the buck at $900. Suppose to lower temps by 25 degrees. Not sure if that justifies expense.

Did this help lower belt temps any?

I've heard MCX won't sell the intercooler separately I'm thinking bigger turbo on these would help to keep the heat down.

Like to know that. I was out today 50 degrees hit 270 short distance on lake 125 degrees iat.

I have tomcat performance 3 inch intercooler which works well and brings down the temp by 20 degrees cooler vs stock side by side comparison with other sled , the only problem with the 3inch intercooler u need to trim plastic and the bumper to fit proper ,

No stock intake
