I posted a question to the wrong list yesterday regarding the Geared
Drive system being offered with a corvette LS 1 engine by Bud Warren.
It was on display at Sun n Fun and seems interesting. Interested in any
comments by those with any experience. Look at the product at

Hi Mark,
I'm not a big fan of alternative engines, but the LS1 (combined with
fuel prices) has opened my eyes.
I'm still not sure if I'll put the LS1 in there or not, but I do know
I'll at least consider it.
Bud and I are members of the same EAA chapter (302). He's a great
resource.
Like I said, I'm still undecided. But there is a lot to like about the
LS1 price, packaging, and options.
Phil

Thanks to all for the suggestions and humor.
I was just taken by surprise as normally I've had a chance to plan for each step.
Harbor freight (only 4 miles from my house) had a sale on the hoist of $147 and
approx $26 for the load leveler.
The engine is now sitting on a four-wheel dolly in the livingroom. VERY understanding
wife and a straight shot back to the sliding glass doors of the workshop
when it's time to put on:^)

Mark,
I don't know much about the LS1, but I did go to the forum that Bud
put on at Sun-N-Fun. I was just curious. Bud or some friend may be
on this list, so this is not meant to be offensive in any way.
My first impression is the man. He seems to know a fair bit about
engines, and since he is the one that makes the PSRU, he must be very
knowledgeable. I don't care if he isn't an engineer. The thing that
bothered me is that he was making comments and borderline making fun
of some of the questions asked in the forum. If I'm trying to sell
someone something, I don't treat them like they are stupid when they
ask a question. The way I saw it, he did that a number of times
during the forum, which I did not like at all.
As far as performance, he said he has tested the engine up to 15,500
and then made a comment something like, "but nobody flies a normally
aspirated engine up that high," insinuating that it has been tested as
high as anybody will want to take it. It has been mentioned a number
of times on this list that people have gone well above 18,000 to
either get over weather or to test the service ceiling. While I don't
recommend flying over 18,000 feet for a number of reasons, I regularly
recommend that people fly as high as 18,000 because of economy. While
the LS1 will likely handle that altitude well, is has not been tested.
The next thing that didn't seem to add up much was that he kept
mentioning that it is a 350HP engine. As I asked further, I found
that it can make that HP at high RPM, while still below redline on the
engine, but they never turn it above 3900 rpm. In this case you are
never over something like 270HP if I remember correctly. Why does he
keep saying that it can make 350HP when they never take it over 270?
I don't know, and 270HP is plenty of power for this plane. It is
likely that even though you don't take full power at takeoff and low
climb, you may be able to make more power at altitude since the engine
is capable of more, but I don't know, since you are still not turning
it faster. Someone a lot smarter than me will have to address that.
I'm just sharing observations.
After the forum I actually went by and saw the engine. It was
impressive. It really looked good, and I was very impressed that
their PSRU has a prop governor pad so you can use a standard governor
and constant speed prop, and don't have to go with an electric prop.
I really did like that. The centrifugal clutch is an interesting
concept, engaging the prop at around 700rpm. When asked in the forum
what happens if it disengages in flight, he simply said that it wasn't
possible for that to happen.
It appeared to fit within what looked like a standard cowl, maybe not
needing the lower air intake hole, but it has not flown yet in a -10,
so there are no numbers. It will take a pioneer to actually test it
in that respect. The firewall forward is developed, so that should
take out a little of the guesswork, and Bud has taken the time to make
it fit and to get the nose gear system incorporated, so it seems like
it is further along than the Subaru was when Dan started working with
Jan years ago.
So, this is just my impression based on going to the forum and seeing
the engine run at idle. I don't know anything else about it or about
Bud.

Sorry it took so long for me to acknowledge your response. My
mother-in-law passed away last weekend and have been pre-occupied on family
issues this week.
As soon as I read your response, it was the my hand hitting my forehead and
wondering why I didn't think of the obvious. I had already prebuilt ahead
to get economies for priming. I just didn't build far enough ahead yet.
I think Van's should move chapter 20 up for at least match drilling. That
makes so much more sense.

Since you bring this up, I will mention that it is much easier to do all of
the deburring, dimpling and priming before anything on the wing is riveted.
My recommended order is to cleco and drill everything, then mark parts very
well and disassemble, debur, dimple and prime all parts, then install the
wing ribs to the spar, then the rear spar, then the outboard leading edge
(so you can squeeze the rivets onto the spar flange), then the top skins,
then the fuel tank, then the bottom skins, then the aileron controls. YMMV,
but this works really well in my experience and avoids the problems you
mention here.

I've just finished match drilling the wing skins and am getting ready to

I'm curious as to how others handled match drilling, deburring, and dimpling
the bottom side of the wing ribs and rear spar.
While it's easier to do now before riveting the top skin the wing ribs, I
suspect it's probably better to wait until the bottom skins are attached for
a more perfect fit. My thoughts are that I will probably have to touch up
the priming after final match drilling and dimpling.

I tried the archives but no joy. Is there any side-by-side in-the-air
data available on the 2 or 3 blade props??? I seem to recall some
comments about efficiency ..... but don't recall the facts (if there are
any) or which way the discussion went.
Any takers???

Does anyone know if the fuel tanks would have to have return lines
plumbed into them as on the egg subie??? I'm not to the engine part yet
and probably wont be for some time but the tanks are nearing and if I
would decide to go the auto-conversion route with an engine I would
prefer to not have to modify the tanks on an already built wing!!!
