Intercooler or Non Intercooled.

[06 Dragon]

Which is better intercooled turbo or non intercooled turbo? There are kits out there that have both. From information i have read, is that you don't need an intercooler if you dont go above 14 lbs boost. Planning on installing an Aero 66 on a 09 D8. HM turbos makes a kit with water/air intercooling 240 HP, The other kit 220 no intercooler and lighter. Only planning on running 10-12 lbs boost.

About halfway down page 6. Glengine will be one guy you can talk to, he knows lots. Hope this topic sheds some light on it for ya though, it was a good thread to learn from.

Interesting to see that at 8000ft, the sled lost 30hp from sea level.... It is amazing what oxygen deficiency does to a motor.

I think??? its 4% loss of total HP for every 1000 ft above sea level. Im sure if im wrong some one will correct me.

I heard exactly the same fact.

i personally dont think you need one at 10-12 psi. unless you are making long wot pulls(30sec+at wot) that said if the intercooler is set up right there are benifits. i dont know alot about the water/air intercollers but water cooling is a great idea. you definitley want a electric fan behind a regular cooler. i have talked to numerous people and if you are playing in the trees or meadows were ther isnt alot of air movement across the cooler you end up heatsoaking the cooler and this actually is worse than not having one and this can lead to detonation and burndown. get as much info as you can talk to different builders before you decide.

ps definitley get boosted intercooler or not :

good luck

If you want to put an aerocharger on do NOT put an intercooler on.. They dont work nearly aswell with one as without.. No matter what boost level you are running.. It's like an air filter definitely do NOT put one on an aerocharger turbo either as it can cause the turbo to over spool and do damage to the vanes inside the turbo..

isnt it 3% for 1000'

thats a good point. i didnt realize the 66's were having that issue. i knew the 53's couldnt have any restriction eg air filter. learn something new every day

Thanks guys, Still researching.Glengine what kit do you run on the 09 d8's, is it similar to MM's ?

 

[06 Dragon]

Oh I forgot one kit runs an attitude controller, the other a dobek. Not sure if thats spelled correctly. Any differences or preferences?

 

[glengine]

The kits turbo kits that i get will be very similar.. Also the attitude boxes are the same as the dobek boxes as they are all made by the same people.. But the aero kit will work slick on that sled..

An intercooler is free HP cooler air higher density, if you can't run one due to turbo restrictions thats different.

I think you might be mistaken, I know Shane at HM Turbos and I am certain that his kit WITH the intercooler works. I think the relationship that he has with the guys at Aerocharger allowed him to build a well engineered kit that takes advantage of the Aerochargers spool up time and efficiency. How many other Polaris kit builders are featured on their site? In fact Aerocharger is selling Shane's kits.

That could be now.. All's i know is that when we talked to brad from aerocharger last winter he said DO NOT put an intercooler onto one of there turbo's.. Thats the info i was goin from.. If you aren't going to run it at like 12lbs boost plus then i don't think that there is any need for an intercooler, also if you cant keep cold air going across the intercooler it will hinder performance aswell.. Just my thoughts.. If there is some new info from aerocharger i'd gladly like to know.. I might have to give brad a call in the next couple of days to find out if things have changed with the turbo set-ups this winter.

Just curious if you spoke with Brad at Aerocharger? I know you folks are probably swamped with work. This is quite a difference of opinions. One outfit saying that is designed with the help of aerocharger and to use the intercooled system being HM Turbos and others with out. More info please when you folks get a moment. Thanks.

I think the suggestion of not using an intercooler had something to do with the fact that the 66 series turbo had not come out yet and the 53 series had some limitations when partnered with the intercooler. I would be curious as to what Brad thinks as well.

Anymore info from Brad yet?

I can't get a hold of Brad, but I am going to Lolo to pick up my sled on the 26th and try to get more information about the intercooler.
