Boondocker intercooler completely blocked off inside?

I just pulled my bd ic off of my new to me t-rx1. Is the inside of the ic supposed to have a flat piece of aluminum tacked inside right before the carbs? It doesn't look like any air could flow through it.

cooler

Ihave heard of people drilling holes in the plate you are talking about to make more hp. with those coolers . I think the plate is in the cooler to even out the boost across outlets
 
I posted a pic. The aluminum plate goes all the way around with maybe a 1/16" gap around the outside edge. How can this thing flow any air?
 
like wilbily said due to placement of ic inlet the air does not flow even across the cores so this keeps and even amount of air to each core. drilling holes would most likely give you a decent gain in airflow and power but you run the risk of having uneven flow to each cylinder which could raise havoc with running rich or lean in different cylinders
 
Flow Plate,

Here is a question, I am currently building a intercooler for my turbo vector. Would it be best to have something to even out flow? Do the newer turbo kit ic have something in them to even out flow?

I ran across something somewhere(can't remember where). They were checking flow on a intercooler. Someone had set one up with a large squirrel cage fan and recorded airflow for each tube of the ic and it was pretty even surprisingly. Was a standard end tank on the inlet side much like how most of the sled IC's are.
 
I don't know if I'd put one in an i/c. I still don't know how any air can flow around it. I've been doing some research and haven't seen any other i/c's like this.

If you look on the powderlites website they claim about how their intercooler design provides even and proper flow to each cylinder.
 
just pulled one off a mpi system today turned it over it has no plate in it . Maybe it is not as important as some people think it is ? I do not like super charger systems but mpi workmenship looks like top shelf stuff so i would think if the plate was that important they would have installed it in thier cooler . I think i would want something in the cooler to even out the air flow
 
I contacted Boondocker and they said this is an updated version. They also said that it flows more than what I can see and if I took it apart it would make more sense.

Here is a pic of the carb end tank I am putting on my sled right now. Directly from the IC. I Hard to understand how airflow could be better if it had to change directions. To change directions it have to stop of slow down. That is why it is best to have the least amounts of bends in the charge tube. Or the largest radius bend that you can get.

turbo 583 under chagre doesnt the system have more air then the motor can take in and if that is so wouldnt it be better to slow the charge air down within reason for cooling ? just like and radiator with no thermosat if you run water through it to fast you do not get a good temp drop

I understand that slowing it down would help to cool the air. But we are talking about airflow. Realistically at 10 lbs of boost your going to see 10 psi anywhere on your end tank(carb side) of your ic, Correct?

I am not a rocket scientist just trying to learn myself. So it this plate helping the IC be efficent and maybe not helping from a airflow standpoint?
 
airflow is crazy stuff, sometimes it takes a way to slow and even the flow to make it run better.. it may cause a little bit of restriction, but if your turbo is moving plenty of air, i can see the benefit of even distribution.
 
Here is my thought about this IC after pm'ing you. With the offset that it has. The airflow out of the IC may be poor to the right carb as it doesn't have IC tubes that are flowing in front of it. That is my guess why they partly need to redirect airflow. Compared to other ic's that the cooling tubes can flow staight into the carbs all the way across.

On another note is this off the sled that was on ebay a few weeks ago, in rapid city? Looked like a very nice sled.
 
last year i looked at a cut away of the ski-doo 1200 cooler . all of the inlets going to the throttle body had air horns . i dont know if they are trying to speed the air back up or even the flow back out ?
 
turbo 583 have figured a way to dump the boost off of the carbs . so when have to let out of the throttle at the top off a pull to make a move around a rock ,tree etc. the engine floods if your not real smoth with throttle
 
Please share

Wilbilly, explain? I will be running a BOV. on the other end of the intercooler. I wonder if there is any benefit to running one on each end? Is this flame out problem something that happens on the rx1 and the vector?

I am trying to take some of the best ideas from every turbo builders kit and incorporate them into my build. And I think that many can benefit from the knowledge the some have on this site from years of running big boost on the yamahas.

Hopefully you will share yours.

Thanks

This is the sled that was on ebay. I was going to do a mid mount kit on my other rear mount rx-1, but instead I just bought this one and now I have two of them. You just can't build these things for as cheap as they sell for, and I am not an efi fan. Too many sensors and too many things to go wrong IMO. These carbed sleds run great when you now how to set them up. And you can turn the boost up to 30lbs, if you have a turbo and octane to support it.
 
Have you called Boondocker?

I have had the opportunity to spend some time with them and they always have a good reason for how they design things.

I would just give them a call and ask to talk to Rocky or Junior.
