If you go to the 130hp ULPower engine you don't have to modify the firewall at all. The engine weighs 178lbs all up, and the only fiberglass mod needed would be to the top half of the cowling. No need for mixture control or carb heat since it is a Fuel injected FADEC controlled engine. Richard On Tue, Mar 10, 2020, 3:59 PM Richard Thomson <richard@...> wrote:

Can you elaborate on the performance that you have seen with the UL 130 hp engine?

That is correct. The reason was to make room for larger mag box and help reduce more forward CG. You can make a bigger header now since there is less need for the 9” of room behind the panel that was required in 1984. All the Avionics are much smaller now, so I made a much bigger header by extending the dimensions towards the rear. Might be a good idea if you want more fuel for the larger engine.
Cheers, Jay

The plans also show a smaller header tank on the Q200. On 10/03/2020 13:25, Brian Larick wrote:

I have a set of those. Takes away any concern for overheating the heads. All included it added maybe 7 or 8 pounds. I love them, but with the new all aluminum jugs on the latest Jab, it probably is not needed. I think they (Jabiru) redesigned the jugs in part to prevent Rotec from selling their heads to future Jab owners. Jab is miffed that after-market jobbers are making parts that modify their product…even when it makes it better than the original.

Nobody that I know of has put one in a Q200 so it remains a mystery. The 0200 running strong and with a good prop can do 210 or more flat out. I think Sam is touching the 220mph mark. I would think you should get the same or better with 130hp.
Speed is an interesting thing however and there are many more factors to going fast than just horse power. ----------------------------------------- From: "Rik"To: main@Q-List.groups.io Cc: Sent: Tuesday March 10 2020 3:19:05PM Subject: Re: [Q-List] Q2 to to Q200 Can you elaborate on the performance that you have seen with the UL 130 hp engine? |
