 |
|
Saw an ad for this product today in KitPlanes – liquid cooled heads for the Jabiru Engines.
http://www.rotecaerosport.com/product-info/lch/
I rarely have cooling problems on my 3300A. Evening though I’m in Arizona, worst case is if the engine gets heat soaked on the ground I have to baby the plane to altitude to avoid going over 350F CHTs during our hot summer days.
That said, I know others do and this seems like an interesting product. If nothing else, I would feel better about ‘de-stressing the engine’ by running it cooler and distributing the heat load evenly which is impossible to do with the air cooled/carb setup.
Pete, any thoughts on this?
Thanks!

Hi Don,
I have just completed fitting a set of the Rotec Liquid Cooled Heads on a J230 that had chronic overheating issues, such that it had to have two heads reconditioned at less than 100 hrs from new, and again at 200 hrs. I made some mods to the carb and induction plenum to try and get better distribution, but the LC heads have made a huge difference.
I have even gone down 2 sizes in main jet (#245) and temps are , if anything, a bit on the cool side. Very straightforward to fit and sort out the plumbing. Added 16 lbs to the weight, but am looking at ditching the muffler and running a pair of 3-1 collectors, which should get about 5-6 lbs off.
We have tried everything else, and it has worked for us.

I am also in Phoenix and have a Hyd 3300 on a Titan Tornado and am concerned about High Temps and Head Wear. The water cooled heads look good but are a bit pricey. I am also concerned that the 20 amp Alternator will not put out enough current to run the water pump as I already have low amperage issues. Does anyone know what our original heads are worth in attempt to sell them to offset the cost of the water cooled heads?<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Hi Todd.
I don't think the old heads will be worth much. I do know that the Rotec LC heads are CHEAPER than the Jabiru ones. You have a valid point about alternator output. We used the larger of the two electric water pumps available, and it has not been an issue with the J230 which has a full glass panel , strobes, beacon, GPS etc.. We do have the pump wired to a separate switch for starting, but after jetting the carb it is starting easily in the cold weather we have this time of year.
Cheers
Martin

Todd,
For the record, I replaced all the strobes and position lights with LED types and reduced the current demand significantly, Now all the lights together are an average of about 1 amp. The Jabiru does not have much margin but with the LED lights, I believe the load of the water pump could be tolerated.

For what it worth, I have the LED setup on my plane and love it and was pretty much essential after seeing the AMP draw of traditional landing light(s), strobes, etc.
Just thinking out loud …
One of the things I’ve been tossing around in the back of my head is to switch out the bing carb. I tend to like to fly at the higher power ratings and get taxed heavily with excessive fuel burn rates using the bing carb. As such, going to a more traditional carb where I can adjust the mixture might make sense and would solve the high burn rate issue (assumption here?), as would probably messing with the bing needles if I stuck with a bing carb. In either case though, if I do that, chances are my temps will climb so it is a bit of a balancing act for sure. I’m thinking that the LC heads would allow me to have the best of both worlds (low fuel burn rates, high power settings, low temps) even on a hot day sort of thing…
Don
P.S. Todd, where are you based in AZ? Any chance over at P19? I thought I saw a Titan there the other day. If so, I’m the red/white Zodie by the fuel pumps.

I am also in Phoenix and have a Hyd 3300 on a Titan Tornado and am concerned about High Temps and Head Wear. The water cooled heads look good but are a bit pricey. I am also concerned that the 20 amp Alternator will not put out enough current to run the water pump as I already have low amperage issues. Does anyone know what our original heads are worth in attempt to sell them to offset the cost of the water cooled heads?

Hi Don,
I have just completed fitting a set of the Rotec Liquid Cooled Heads on a J230 that had chronic overheating issues, such that it had to have two heads reconditioned at less than 100 hrs from new, and again at 200 hrs. I made some mods to the carb and induction plenum to try and get better distribution, but the LC heads have made a huge difference.
I have even gone down 2 sizes in main jet (#245) and temps are , if anything, a bit on the cool side. Very straightforward to fit and sort out the plumbing. Added 16 lbs to the weight, but am looking at ditching the muffler and running a pair of 3-1 collectors, which should get about 5-6 lbs off.
We have tried everything else, and it has worked for us.

Hi Don,
As Richard pointed out, there is a lot on Youtube, but the Rotec website is full of great stuff. If you want pics of our own installation, email me directly and I can send to you. Our installation is overly conservative. We live in a hot part of the world so I oversized the radiator and placed it directly under the prop. I had to add an inline thermostat to get some temps into it. When I do another one, the radiator will be 1/2 the size and placed under the engine.
Cheers
Martin

Don,
You have a few options regarding a mixture adjusting carb - Aerocarb, Ellison TB and Rotec TB. I have used both the Aerocarb and the Rotec TBI, and the Rotec unit is the more sophisticated. If you are running unleaded fuel, you might also like to consider adding a wide-band Air Fuel Ratio meter. Makes getting the correct mixture a breeze.
Also permits running LOP if you are interested in another tin of worms......
Cheers
Martin

One of the things I’ve been tossing around in the back of my head is to switch out the bing carb. I tend to like to fly at the higher power ratings and get taxed heavily with excessive fuel burn rates using the bing carb. As such, going to a more traditional carb where I can adjust the mixture might make sense and would solve the high burn rate issue (assumption here?), as would probably messing with the bing needles if I stuck with a bing carb. In either case though, if I do that, chances are my temps will climb so it is a bit of a balancing act for sure. I’m thinking that the LC heads would allow me to have the best of both worlds (low fuel burn rates, high power settings, low temps) even on a hot day sort of thing…

P.S. Todd, where are you based in AZ? Any chance over at P19? I thought I saw a Titan there the other day. If so, I’m the red/white Zodie by the fuel pumps.

Todd,
For the record, I replaced all the strobes and position lights with LED types and reduced the current demand significantly, Now all the lights together are an average of about 1 amp. The Jabiru does not have much margin but with the LED lights, I believe the load of the water pump could be tolerated.

Not sure they will be at OSH though

Todd,
For the record, I replaced all the strobes and position lights with LED types and reduced the current demand significantly, Now all the lights together are an average of about 1 amp. The Jabiru does not have much margin but with the LED lights, I believe the load of the water pump could be tolerated.

Does anyone know what our original heads are worth in attempt to sell them to offset the cost of the water cooled heads?

Hi Don,
I have just completed fitting a set of the Rotec Liquid Cooled Heads on a J230 that had chronic overheating issues, such that it had to have two heads reconditioned at less than 100 hrs from new, and again at 200 hrs. I made some mods to the carb and induction plenum to try and get better distribution, but the LC heads have made a huge difference.
I have even gone down 2 sizes in main jet (#245) and temps are , if anything, a bit on the cool side. Very straightforward to fit and sort out the plumbing. Added 16 lbs to the weight, but am looking at ditching the muffler and running a pair of 3-1 collectors, which should get about 5-6 lbs off.
We have tried everything else, and it has worked for us.

I rarely have cooling problems on my 3300A. Evening though I’m in Arizona, worst case is if the engine gets heat soaked on the ground I have to baby the plane to altitude to avoid going over 350F CHTs during our hot summer days.
That said, I know others do and this seems like an interesting product. If nothing else, I would feel better about ‘de-stressing the engine’ by running it cooler and distributing the heat load evenly which is impossible to do with the air cooled/carb setup.
Pete, any thoughts on this?
Thanks!

Thanks, Marty....I'll look at Osh, but for the Jegs stuff I'll wait
until I get back home and then check 'em out.

What make of A/F meter do you have, Martin? Answer quickly, as I'm
heading to Oshkosh with room on my credit card (but none on my

Don,
You have a few options regarding a mixture adjusting carb -
Aerocarb, Ellison TB and Rotec TB. I have used both the Aerocarb
and the Rotec TBI, and the Rotec unit is the more sophisticated.
If you are running unleaded fuel, you might also like to consider
adding a wide-band Air Fuel Ratio meter. Makes getting the correct
mixture a breeze.
Also permits running LOP if you are interested in another tin of
worms.......

One of the things Ive been tossing around in the back of my head

power ratings and get taxed heavily with excessive fuel burn rates
using the bing carb. As such, going to a more traditional carb
where I can adjust the mixture might make sense and would solve the
high burn rate issue (assumption here?), as would probably messing
with the bing needles if I stuck with a bing carb. In either case
though, if I do that, chances are my temps will climb so it is a
bit of a balancing act for sure. Im thinking that the LC heads
would allow me to have the best of both worlds (low fuel burn
rates, high power settings, low temps) even on a hot day sort of
thing

Thanks for all the great advice! Didn’t even know about the Air Fuel Ratio Meters – did a quick search – those are cool and I do love my gadgets <g>!

Don,
I am really impressed with the AFR gauge. Whilst it doesn't monitor each
individual cylinder, it does tell you what the engine is doing mixture-wise
