The OS FT120 is a solid 2 hp engine and will spin a 15x8 @ 9400, 16x8 @8000.

The Saito FA-91 is a 1.6 hp engine and will spin 14x8 @ 9400, 15x8 @8000.

No contest really.

Power to weight ratio? The Gemini is pretty heavy.

OS FT120 is .0019hp/gr
Saito FA-91 is .0027hp/gr

Some things to consider:

How much nose weight would you need to add when using the 91? If you have to add upwards of 300 gr then the 120 would be a good choice.

Do you have ground clearance for a 15" prop? If not then the 91 may be a better choice.

Do you want unlimited vertical? Larger diameter props make more thrust so the 120 would win out.

it's story time.

my friend was a real tough guy back in his younger years, at 10 he could pick up a 4 cylinder Renault engine and he is not at all a big guy! his strength all can from his mind. his father and brother would fight him, rolling around on the floor fighting with him. that all stopped in that last fight because my friend won that fight, his father and brother got up and ran, he was 10y.o. he said it was all because I was there to watch. and that was the first time I ever went to his house. well in his early 20s he worked at a spring shop, he would replace the springs on 18 wheelers, pick-up and cars.

well he had a firstG Bronco. 70, 71 ???. and he lifted it and put 35" sneakers on it. I had my 47 Willys with 32" on it. we went 4 wheeling and he turned vary sharply at the top of a hill to go down it's steep side and the Bronco went up on 2 wheel and all most rolled over. of course I had to tell him his sneakers were too big and that I will never go bigger than 32"s.

well, you know when big is not big enough you go bigger. or real big. about a week later I stopped at the spring shop. and my god there sat his Bronco with even more lift and 44" Growndhog sneakers. wow that Bronco looked so cool.

so about a week goes by and I stop at my friends house and he and his cosine are standing in the driveway and his cosine had a cast on his arm and there sat the bronco with the whole top whipped clean off and the front finder was all smashed up..

sO,,,, LOL I asked what happen and he said he was up on an old dirt road and his cosine said "go that way" and so my friend wiped the steering wheel to the left real fast and the Bronco went sideways and flipped.
my friend then said "it's no biggy.

the Punch Line;
his cosine with his arm in the cast say>>>> "no biggy for you"

Hey Dave did you received the 150 ? I received the 100 just 15 minutes ago, I owe you more than a thank you, but thank you.. wow this engine is so beautiful. it's every bit impressive as it's larger silver brother, the 150. I told my Son that he will get this engine some day and I do not want him to ever sell it !!

now I have to decide what plane it will complement the most.

Worlds Model M-Mustang; yellow and black zipping around sure go together nicely.
or,
Phoenix Ryan STA; a classy black engine for a classy white, old time racer.
or,
VQ P-40; a classy black engine in a classy old fighter. the enemy wont be seeing the son reflecting of that engine.

thanks Dave, I don't know what to say that will reflect my feelings ! but I can say that I have never known a bunch of better friends. any one that comes to know you guys will for sure have a better life for knowing you all !!

Thanks Jim, yes the 150 and the 56 arrived about 4:30 pm. Both are jewels, the 56 is a little stiff but otherwise fine. Thanks Jim and Texas Pete.

I came up with a better way to build the velocity stacks, I counterbore the carb inlet to 9mm x .25" deep. A 9mm K&S tube is firm push slip fit into that, of course I flair the bottom end.

.25" deep counterbore

9+ mm K&S tube

Complete and totally sealed for good chocking.

Sounds like tour cousn found out those old furd Broncos have something in common with the old Jeep CJ! Spend more time on their tops and sides than on the wheels.


Dave,

Reminds me of a Paul Simon song;

"Must Be 50 Ways To Make a Velocity Stack" LOL!

when my son was 13 he came to me and asked "what is it with the girls in JH school". he went on to say that they will give you a really big smile and say hi to you as you walk by them in the hall.

but later if you try talking to them they get sharp and sassy.

sO I told him about the birds and the bees.

and don't you know it, a week later he comes running all upset, he got stung by a bee, he thought he was going to a father.

Easy enough to check, just pull out the old tachometer

One or two little spots of blue Loctite would help to ensure it stays put.
Easy to release, if needed with a little heat from your soldering iron.
Gotta love it Dave, aint this hobby fun?

Thanks gentlemen, they nearly look like a smoothbore when looking through them, before I slide the O-ring and the clip on, they get a small amount of Red Loc-Tite,

My wife and I rented a Samurai and drove it all over Aruba during one of our many Caribbean vacations. It got us around OK. Didn't feel too tippie.

The scariest part of the drive was when we stopped to snorkel and a two armed prison gaurds pulled up in a Jeep. They told us we were too close to the prison and should move on.

An old boss of mine was vacationing in Cancun and rented a Jeep. The scariest part was the armed military police stopping cars to check to see if the driver was wearing a seat belt.

Like most vehicles, there are limits, know the limits - avoid disasters !
The problem that got the narrow track CJ into trouble with Big Brother at the time was that the thing gave very little warning. The un-intiated felt fully in control until they attempted what seemed to be a rational maneuver. Bang, they were on their side, often with severe injury to limbs since so many chose to be sporty and run without doors.

After a huge number of such events, Uncle Sam did some testing, made his move and the new Jeep was born. Made a lot ot the trafitional Jeep creatures pretty angry to lose their beloved narrow track trail buster. I kinda liked them too! The Samurai was quite similar, a large percentage wound up in the crusher after catching an unwary driver off guard. Those narrow trackers are far better off-road than on in many ways.

I had a 1959 Triumph TR-3A they were narrow track and with the solid rear axe they could really hop in a tight curve. The saving grace was it was real low to the ground. My wife could file her nails on the street when we pulled up to a light. I remember one old race car driver from back in the day was quoted as saying the TR-3 was the only car he knew you could roll in your garage.

When I was in High School a buddy of mine had a TR3. He put a tr4 tranny inn it, 4 speeds (if I remember correctly). We had a blast in that thing. He was always fussing with the carbs, then replaced them with American carb (s) of some sort. That may have never been all that fast on the top end but it sure was nimble.

We used to head to the hills a few miles from town and race up one side and see how much air we could get on the back side. We found a great that was good going both ways. We went out once and got some good air on the back side only to find another car some one else doing the same from the other side. You can't steer or brake when all four tires have air under them. the other car braked and swerved though, but ended up in one of the almond orchards that was on both side. Don't know how the missed finding a tree. We went back and helped them get out since they got stuck. Didn't stop us from the fun and games though, but we then tuck a third kid to be traffic cop at the top of the hill.

At some point he traded the TR for a 60 T Bird. Bored it out all the way, Holey carb and some other things. Now that was scary fast.

I don't know if he gained anything installing a TR-4 tranny there wasn't much difference. I had the electric overdrive which was fun to play with along with both hard and soft tops. I know Thorsen made a supercharger but it was anything but bolt on. I knew a guy who worked at a machine shop and they had a guy bring one in. It cost him a fortune to get it installed.
