Cooling down the intake temps when warm out - hot!

[fourload]

Damn that windshield is a monster!!!

I have the same Granda monster!! Also a medium when I want to look cool on warmer days. The tall one is so warm though. With Knapp's hp who cares about a little wind resistance!

Same intake track that's on all the sidewinders, just pulling from top instead of the sides. Still cold fresh air there. The stock Winder pulls cold air stock. Much cooler stock than from under the hood where the aftermarket CAI's are going.

Mike - does your Winder have the goggle bag or the plastic mesh cover? Just thinking about letting some hot air escape.

Plastic mesh, along with the stock intake tunnel removed for added heat escape out of the top when running the CAI.

Does anyone know how fast these IAT sensors react? Or where it is located?

I have very different results from what many here are seeing. My IATs stay pretty cool when Im just trail riding, but they dont seem to move up or down very fast. When its below zero, they are within 10 degrees Celsius of ambient, and when its warmer, they are maybe 15 more than ambient.

Either way, the stock intercooler is not large enough with more boost. These aftermarket intercoolers dont seem to run much cooler than stock, so maybe meth injection is the answer. For racing, it would certainly be faster to eliminate the stock intercooler, and run meth injection just after the compressor.

700usd for an intercooler buys alot of washer fluid.

So I keep going back to one of the original premises - would we get more airflow through the intercooler without the solid nose plate directly behind it? Travis showed a puller fan doesn't (yet) help. I would think the factory engineers know something I don't, BUT, I ordered some Frogskin vents and will be cutting out some big holes in the nose plate behind the intercooler to see if that helps. If nothing else, it will flow more air through the engine bay and maybe keep the clutches cooler. If it does the opposite I'll just put some aluminum back over the holes I cut. Stay tuned.

My solution to getting actual ambient cold air in to the intake. Water resistant Outerwears sock is ordered as I know it will be needed for snow usage. I hate the fact its outside the hood, but I'll order up a new factory screen that has to have a hole put in it so very easy to go back to stock, no need to put holes in hoods that is irreversible or anything like that. If I don't like it, I can go back easy enough.

Reminds me of the filters that stuck out from the side of the old Cat Suzuki 1100 turbos between the a-arms on the clutch side.

I just had to ad on to the inlet tube with a silicone coupler and length of formed and curved alum tube, then put a hole thru the factory screen. If it adds power or makes it more consistent, which I believe it will do both, I'm all for it. Its not a beauty contest after all.

Mike, any results yet? Also wondering if you have a few photos close up of it going through the screen and what its looks like behind the screen, etc.

Thanks!

Art, Its back under the hood where it was. With it hanging out of the hood, it went leaner than I'd like to see it. I need to do more testing with it next season, but it does draw clean, fresh cool air.

Ah. Maybe once GAP releases the fine tuning mode and we can add fuel for changes like that - will be a super powerful feature. Keep us posted.

I wonder if the mountain guys that have them sticking out the hoods are finding lean issues or possibly because the air gets so thin up there they don't have any issues. Would have been nice if Yamaha went mass-air instead of speed-density, but that would have come with more cost.

I went ahead and installed a thru hood intake. I love the look and must say that I did miss the spooling sound my MPI viper made when I poked the intake thru the hood. Intake temp will definitely be colder and I will keep an eye on the AFRs.

Mass air is actually worse for a high performance engine. Many subarus wrx when turned up are converted to speed density. My brother put an LS3 into his mustang, the aftermarket ecu converts that to speed density too. Pretty sure mass-air is just better for emissions, and better driveability in a wider range of conditions and temperatures.

So what was the results, fix?

 

[geez150]

I feel like no one knows at this point, could be wrong though....

 

[kinger]

I am still shocked how small the IC is compared to my apex IC's .

In my opinion Art...

I wouldnt do that...now all the heated air enters your engine bay vs being directed out right and left....

if you want to get more air through the engine bay...remove the upper intake tract which is not used with a CAI and add venting to the front and side panels ala mo vents or frog skins....

with the stock airbox sealed and getting outside air...then maybe that would be something to try...

Its really not that small. Bigger intercooler isn't always better. Theres engineering into the needed size and flow etc. Going even bigger if you arent running real high boots at real long distances (I.e speed runs or drag racing) you won't see or feel much even with data logging. Going too big can also have the reverse effect on spool times especially on and off throttle situations. That's all the more volume that has to be "filled" before getting into the throttle bodies and engine. Bends angles etc all come in to the efficiency as well
