Hey, what size oil cooler to the RV-10's use?  Is it the same on on the -7's and -8's?  "Oil Cooler II".  Or, do they use a larger one?



I've got a SW10610R for my IO-390 on the RV-8 which is a monster sized cooler.  The stock "FF-709" mounting bracket is way too small.  Does Van's have a larger one available?  What's used on the RV-10?



I guess that I could make one, but I'd rather Van's CNC punch did, if you know what I mean...?



Thanks!

I do not know about Van's, but Alex  DeDominicis (Aviation tech products)sells one that has the identical dimensions as Van's unit for the 10 and supposedly has 20% better cooling. Alex is a good guy and with the difference from the cost of the Van's product - it was about $100 more. Seems to work fine.

Ditto on the unit from Alex.... with the exception of the reduction in cooling... certainly NOT 20%.... considering 200 degrees, we'd be talking about a 40 degree reduction.  Plan on a reduction of between 5 and 15.

We put the Airflow 2008X on our RV-10 since our oil temps where higher than we liked

 And saw a 10 - 20 degree F drop as a result

 We also installed a baffle that splits the air flow in the Van's standard box per recommendation from Airflow (these guys had a lot of good experience with the RV-10 people)

 You do have to modify Van's oil cooler box to bolt the 2008X on inplace of the standard cooler, but it can be done.  Basically you have to turn the cooler 90 degrees and fold out the vertical sides of the box, drill a few holes and bolt on.  Actually pretty simple change.  I felt it was worth 

  

 High oil temps for us was only during summer hot days coupled with slow flight conditions 120 -  150 mph range. if you keep the speed up to 160 or better its usually ok

 Example would be 90 degree day and slow flight around the pattern or sight seeing low and slow the temp would get up to 230 F.  Now with larger cooler it only hits 210 F.  Our 6 position CHT numbers have always been 350 or lower regarding engine temp, so the cowling / baffling seams tight and working good.

 The slow flght condition appears to be more of the issue.  I would bet a cowl flap right under the cooler would also work, be interested to hear if any one has done that yet.

Does anyone have photos of this "splitter" vane thing that people

are putting in the filter box?  It sounds great, and I've heard

tons about it, but never seen a photo.

Tim,



I don't have a picture, but I'll try and describe it.



The 'splitter' itself is a piece of .032. It is the same width as the 

inside dimension of the oil cooler mounting box. Its depth (from memory) 

is about 3 1/2 " the bottom 3/4" of an inch of the splitter is bent with 

an angle of 30-45 degs. The splitter comes with 2 .032 alum angle "L" 

tabs. that are about 1/2" wide and 1/2-5/8" long. I installed mine by 

pop riveting the angle flanges flush with the top of the splitter, Then 

installe the splitter/diverter flange inside of the mounting and place 

it midway across the circular opening. Drill (match)  a # 30 hole so 

that you can pop rivet the flanges to the top of the mounting . 9The 

bent part of the splitter is facing forwaed. The theory is that the air 

coming from the scat is split and the splitter pushes 1/2 of the air 

towards the top of the oil cooler. the reports were that without it the 

pressures builds up on the bottom of the wedge and more air passes 

through the bottom than the top.

No photo - but I think we had a drawing >From Airflow that I can dig out and scan

 It's at the airport so may take a few days to get back to you

 Later

Mike, that will be awesome if you can get the drawing.

Maybe they'll send it to me if I ask. I'll see.

Nope, they give the drawing with the kit, which is $49.

I may have to get me one.

When I built my RV8, I attempted to use the SW cooler recommended by vans, 

however it was inadequate.  Upon advice of Monty  Barrette, and Dave Anders 

(still the fastest RV) I obtained a Niagara/Harrison 10 cooler and mounted 

it on the rear baffle behind cyl 4 and tilted it down approximately 35 

degrees (tilt as much as possible without contacting engine mount) (it will 

be necessary to remove some metal from the flange on the cooler to prevent 

contact with engine mount tube). This set up has proven to be excellent 

providing good cooling in all temperatures up to 95 degrees outside air 

including the Air Venture races when I run at 100 percent of power  at low 

altitude for over 2 hours  (2700 rpm, 27-29 inch manifold pressure) average 

indicated airspeeds are 220-235mph depending on OAT.

Thanks for the feedback Richard.  Do you have some pictures of your installation you could post to the Lists?



BTW, your computer clock is 5 days behind.
