Jabiru LCH testing - FANTASTIC Temps! by Rotec Aerosport

Your evidence is a movie clip with some water cooled heads, big deal. Shows us some performance data, added weight, radiator positions, cowlings modification and whatnot before you call people trolls not agreeing with you.

@rph310346 fair. will be happy to provided you with this data/information. more will be available on the website soon. nonetheless thankyou for your advice.

[rph310346]

Now to offer liquid cooling heads knowing the air cooled heads are a problem is screwing the engine owner twice. Glorified copies don’t work no matter how much water they inject in to. The again, some of the experimental builders will screw any crap on for the pleasure of flying cheap.

@rph310346 is obviously a troll, and takes no attention to the evidence provided. There is no point continuing this discussion.

[rph310346]

it takes a few hundred millions of dollars to do a proper R&D on an aviation engine, this guys are kidding them self’s by liquid cooling the heads other construction problem would disappear, granted it runs , so do many others roos jump in Australia..

@rph310346 while your skepticism is granted, I do not understand your lack of optimism. "a few hundred millions of dollars" to even develop a certified light aircraft engine from scratch is an over statement. These heads are offered to the experimental market, and so far they achieved the goals set.

[rph310346]

Nothing new about it, going Rotax won’t solve their problems.

@rph310346 that's a rather skeptical comment? What other problems does the Jabiru engine have other than the cooling and low oil capacity?

[fb2800]

@rph310346 You dead right.......theres nothing new about liquid cooling in fact 99% of all piston engines are liquid cooled, why? Because it works! Did you know that liquid cools and over 30 x the rate of air? Think about that....30 times.

good show.. can you send me more info about this water-jacket ? would be interesting for my engine.. greeeezzz from switzerland

Absolutley fantastic ! Congratulations from Norway ! Will you produce a 2200 jab kit ? Also, when will you start on the vw heads :) I have a sonex with a 2180cc turbo EFI vw engine. But LCH would really add some amazing cooling performance. Also, I have build a turbo 2200 jab. I puts out 137HP with 42in\Hg MP. Turns a sensenich 54x64" prop to 3050rpms static. Thats a 3300 jab prop machined for the 2200 prop hub. Thomas - EdgePerformance.no

awsome :) glad to see they are being tested!
