xm-turbo intercooler?

[adam8781]

Sorry but for tests I have done on the 3 inch and the
2 1/2 barrel from frozen boost you guys are way off.
at 24 psi in to the barrel I have 24 coming out
at 42 psi out of the barrel I have 45 psi IN pressure. yes there is a drop but not what your getting at.

so at all the levels a trail rider would be at there is NO drop on these barrel styles nor have I experienced any type of soggy bottom...lol sing it boys..

build what you like but get real with your pressure drop and flow resistance thoughts. this aint promod and these are not 88 or 94 inducers flowing like typhoons..

Now we need intercoolers again ??? thought the new data loggers proved to somebody that intercoolers were not needed ???\

anyone giving away a barrel cooler I will give it a home where it will get treated with respect and taken out for play time weekly !!!

I cant find a 2.5 or 3 inch barrel cooler, the long flows come in that size on frozen boost but I only see the barrel coolers in 2.25. link?

The discussion quickly turned to types of interheaters... but my question in the first place though is why do you feel you want one at 7psi?

IMO they don't really shine until 14 or so (ok, I'm biased, it's probably closer to 12, pull length dependent) but can't see any reason to add all that extra weight, restriction, and complexity to a system intended to run well below where an innerheater really starts to shine.

Run a cold air intake, and save money, boost and weight imo.

Try 5 to 6 LBS is when they shine. 12 lbs would be 200 degrees over ambient.

Please explain?

I've never heard anyone say that it makes sense to run an IC on a 5-6psi sled, curious why you feel that is the way to go?

give me some number that everyone can work with.

If I have a climb that lasts _________ seconds i dont want to see ic temps rise by __________________ amount of degrees.

What is my motor displacement?_______________

2stroke or 4 stroke?________________________

what is my hp limit?______________________

What size of charge tube do i have? ________________

What size is my turbo?_______________________

what is my elevation that i ride at?__________________

My charge temps are __________ when is am pulling cold air from outside before a climb?

My charge tube is ______________ degrees after a normal climb?

My boost pressure is ___________________?

+++ to having a inter cooler? ________,_________,______,

Cons to a intercooler?__________, ____________,___________,

extra parts needed for intercooler list + & -?

I can show you datalog after data log of iat temps. theses are at 6,8,10,12, 15, 20 correct psi pressures. Imo Cons out weight the plus's of a intercooler in mtn riding. trail high boost different story.
So if you want a intercooler we will build you one.

I just think guys dont ask the right questions before deciding what products they want. It is all about the completed outcome or goal....

Thats great
8 Lbs, 60 second pull, 0 ambient. 30% race fuel. 2013 800 pro rmk 163
IAT = ?

I'm not sold on the inter-cooler idea at the pressure I am planning on running, I just thought it may make tuning more consistent, and easier. I know an air to air wouldnt be of much help. If you guys figure it wont be overly beneficial I could be convinced to run with out. the weight may be un necessary, I think I will just run without and if its getting heat soaked maybe put one in at a later date. thanks guys

One thing that confuses me about pressure drop on a intercooler is if you take a heated, pressurized volume of air and cool it there will drop in pressure. So is the cooling of air pulling the heated air as it goes through a intercooler? Would there be a difference in pressure drop if your intercooler is 85% efficient compared to 5%.

HI YA Gus,

Maybe there something wrong with the barrel system I built, but my boost gauge is kind of poky getting up there, I am comparing it to a system were the gauge moves so fast you don't even see it move. When your doing your testing I am guessing that it is at a steady state of air flow. Any turbo system I have built with a water to air the gauge just does not move as fast, the small barrel seems to be the slowest gauge mover so far.

And no you cant have my barrel, it will just sit in a sled that is collecting dust

A: Turbonetics and Spearco would like to see everyone run an intercooler of course but it is not mandatory in order to turbocharge your vehicle. That said, all of the Turbonetics Turbo Systems include a custom sized Spearco intercooler to maximize your systems performance. With out an intercooler on most turbo systems the boost pressure and thus horsepower will have to be much lower. This is because as the boost pressure is increased, the air temperature is increased significantly and the engine cannot fit as much air into the cylinder. As air temperature goes up it is not possible to squeeze as much air into the cylinder and without as much air as it could have with an intercooler the HP will be lower.

Read between the lines.......
There are a few on this blog, that would have you think you dont need one. After 5 LBS you do
We have all the snow in the world, to cool your intake air. Take advantage!!!!

 

[taylorbok]

I understand cooler boost will make more hp via denser air, but how much cooler charge temps would one see at say 7 psi if your already using a cold air intake?

gus you don't see anything wrong with barrel style? I cant figure out why it would restrict the flow if they claim it flows an adequate amount, unless there numbers are lies, and who would lie on the internet?

 

[gus bohne]

I am comparing full run data BUT I do use a ams 1000 to control boost rise and rate.. so It could be masking something..

I will check it on my new mach z throttle body injected trail turbo ..

I also have gone without the intercooler on many builds. even at just 5 psi on a TRAIL ride the charge temps are over 100 degrees on the 2871, lower by 30 degrees with the 76 or 82 comps.

almost seems kinda low class to build one today without an air to water..but I am low class so it fits

[taylorbok]

ok I am so lost and confused now. I am going to build it with out i/c run it and get charge temps via koso x-2 gauge, then ill put in the i/c and get temps again

 

[islanddoo]

Very confusing stuff for sure. Don't know if I am right or wrong here but I put an w/air cooler on mine for more consistent charge temps considering it's carbed and all. Don't know exactly what the charge temps are but the charge box is usually just warm even after long pulls and 9lbs. Seems to work for me. Good info on this topic for sure though!

 

[sledhead9825]

If the charge tube is warm to the touch but not hot, long pulls at 9lbs. IMO it is doing its job. Are you happy with how it runs?

 

[islanddoo]

Yah that's what I was thinking, temp really never changes from trail up to climbing so I think for what I was after it gives me a little more consistency in the jetting!
Seems to run fine and build boost quickly it is always a work in progress!
