MTW 110 question?

[Flyinrazrback]

Which MTW cans is everyone running in their Daltons? the long ones, or the short ones, and any performance difference between the regualr MTW 110 and the shorter, wider 110K?

I run the MTW 100s which I've found my 3W 150's love. But my CS157 doesn't seem to like them like the 150's. I'm switching the 157 to KS1090's and will be able to see a difference...I hope.

Ok thanks, I have a set of the 110Ks coming to try on my zdz super 160. You will like the 1090s on your 157, I ran them on my 157 twin spark and it was a monster. However, with those pipes do not load up the motor, as with them the rpms need to go up to get into the pipes power band, I found I liked a fuchs 32x12 best, but one loud mother if you dont keep it under control. Anything 32x10 would go supersonic and could be heard from a few miles away. Run the headers the length they come and the pipe, no shorter.

PS, the 157 can of choice is the 3w LL can. I imagine the MTW 100 might be a tad small for the 157, but the 110 would probably work well.

The 1090's on that 157 are going to make what ever plane it is in a rocket. I have been using both the greves pipes and KS 1090s and am turning a 32x10 mezjlik at 6200 RPM. I would assume your going to get even more then that on the 157.

I think it was up around 6700 or so with the 32x12, the CS on 1090s should be a tad more. My setup was on an AW 39% extra about 39lbs and it could have been used as a pylon racer.

That is a ton of rpm how much noise does it make DB wise. I would think that even with a big prop and quiet cans its still going to scream.

Even with the 32x12 and those rpms, it was the loudest setup I have ever heard on anything, it sounded just like a full scale edge prop ripping, very loud! The problem with the pipes is for the motor to make the power, you need to keep the rpm up, loading it up with a 34x10 or 34x12 is not the correct solution, as it takes it out of the powerband completely just to try to comply with the noise. The motor is so strong to begin with, and adding pipes just cranks up the power. With that kind of power, there is no need to use full power at anytime, even on long uplines. However, I just got my paws on the new zdz super 160, so going to see if it can keep up with or even pass the 157.

Charles, what ever happened to your 157/1090 AW 39%? When you had your screamin 150/1090 you had all kinds of rpm numbers, but nuthin with the 157. Just curious.

I would think the new 160 would surpass the 157 since the super 80 is beating the 80xi. BUT, and here is where I depart performance. Rear inducted! Big ole mess in the motorbox, been there done that. I suppose you can use the butt end of a bud light can to seal it away from the box, and that's exactly what I'd do if I had to deal with rear inducted. But all in all they're a PITA.

Please let us know about the 157.

Yes the rear carb is a PITA, but my dalton already has a big hole in the firewall and it was the same bolt pattern as the DA it replaced, so it dropped in no problem. I have never had a messy motorbox from a rear carb, so cant speak to that. I liked my 3w 80, but honestly was really dissapointed with the performance of it. I thought my old 3w 75 was on par with it, and my 80 was the CS and on a can. It was really smooth and transitioned better than the 75 though. The zdz super 80 is a monster. In reality it will turn with a DA 100, and on an AMT or KS 1080 pipe blows it away. I sure hope the super 160 has the same incrase over the 157 like the super 80 over the 3w 80. The fuchs 32x12 was the only prop I ran on my 157/1090s that I tached. Also tried a Biela 33x12 and Fuchs 32x10 freestyle prop. I have since sold the plane to a friend in Shreveport. I dont think he flys it anymore because he got a comp arf 260. Last I heard he was ripping hard a biela 33x12, which if you have seen it is a huge prop!

Andrew, are you getting the same rpm's with the Greve's pipes that you are with the 1090? I put the greve's in my Comp Arf 260 and with the 28.5-12 3 blade I am running 5950, I only have 3 tanks of fuel through the motor.
