DL55 or EVO58
 
Curious, all out 3D on a 30% Yak with an RE2 tuned pipe, what would you buy, a DL55 or an EVO 58?

Thanks

From reading the posts on both engines, I would buy a DLE 55. Seems to be fewer problems?

I'd go with the MVVS 58 from Pe. One of the best engines built.

A MVVS 58 from Pe is a slightly different engine than the Evolution 58?

Slightly!!!! But essentially the same.

ive seener fewer problems with DL50 DLE55 than most motors out there

RE: DL55 or EVO58
 
But it's about the power.......... do you really think a DL55 can out perform the Evo 58?

Dont worry,you will find out soon enough,the 58 I sent you spins a jc 25x7 @ 6600,i flew my 33% plane w/it,using a small venturi da 50 wt-201 carb,you can play with the 16?mm stock carb,good luck!

RE: DL55 or EVO58
 
it would depend on the all up weight of the plane and if you can use the nose weight of the Evolution58.i have both engines the 55 can't come even close to the HP the 58 makes.
but if the plane comes in at 16lbs. the 55 would be my choice.

Closetguy makes an excellent point that has been overlooked before his post; the Evolution is about a pound heavier than the DLE since it's actually a 60 size engine.

All I have is anecdotal evidence base on what I've seen of the Evolution egines around here vs. what I see posted on the forums and that would suggest that while the Evolution is supposed to be basically the same engine as the MVVS, the MVVS doesn't seem to have the reported problems one sees with the Evolutions. Based on what I've seen around here, there's no way I'd be buying an Evolution.

JMHO, YMMV.....

What could be the largest reason for the difference? They are the same parts!


Thanks again Skip :D

I'm still running the MT57 in my Extreme Flight Yak, 3rd season but I'm wanting more pull out power. We have an original MVVS 58 out at our field with an RE2 pipe and its crazy. I have to be pushing 18Lbs plus on the Yak.

Where do you get 25x8 / 25x7 props?

DLE, hands down.

Hughes,i had the very same set up in a 88"EF yak,evo58 on a mtw pipe ,i was rite at 17.5 lbs.
great set up,LOTS of power,i was spinning a Beila 24-8 prop at 7500.never could get the mid-range throttle response like i wanted ,but i probably never got the perfect length header.
if i was to do it over again i would just buy a MVVS 58 from Pe.i think they pay more attention to assembly.

Wrong way RC.com for props,Rich is great to deal with,check out the site,good stuff,ran his 23x7 on dl 50,16.5lb edge was balistic!

And he's got cool decals ;-)

I'll keep everyone posted, something tells me Skip has it all worked out with the 201 carby ;-)

RE: DL55 or EVO58
 
If you want to sacrifice top end power and fit a smaller carb than the original 16mm one, The WT610 would be a better choice. It has a larger mainjet than the WT201. If flying at altitude, The 201 is OK, but at sea level fuel flow is marginal.

I tend to second that. I have both the 58 and the 80 and both are in a different league.
Comparing the DLE55 and the MVVS58 is not comparing similar engines though because the 58 operates on a very different torque curve.
The low RPM grunt has to be seen to be believed

RE: DL55 or EVO58
 
Not having been around many Zenoah engines, where would the lightened G62 talked about in another thread fit in here? I'm guessing it's a torquer also...

True Ari, Too many on this forum repeat what they read or hear. Those who know this engine have quite different opinions.
Here are the results of comparing the wt201 with WT610 carb. The 201 main jet is 0.88mm, and clearly too small for good adjustments. DA50 users reported the samelimitations with this WT201 carb.
The CHT (Cylinder head temperatures)readings are with same prop, just main jet adjustments were made. Final picture, the engine still was nicely two-stroking on a large prop, but CHT was down to safe levels on my test stand. In flight needs leaner settings due to engine unloading.

The 62 is a poor torquer! it thrives on rpm in excess of 7000. The MVVS works quite well down to 5500 rpm! At these values, exit Zenoah! These two are like apples and prunes! (not even pears)

Hughes500E 09-02-2010 05:34 PM

RE: DL55 or EVO58
 
So where does the 16mm carb fit in here? I'm guessing difficult to adjust or??

With your smoke header and an MTWRE2 pipe, same results as above with the 610 prevailing over the 201

RE: DL55 or EVO58
 
Thanks, I haven't really done much reading the G62, but after I posted this yesterday, I saw another post by Antique(Ralph) that said they were turning 9000+ on a race setup with stock porting, I believe. Not sounding like a torquer...my bad.

RE: DL55 or EVO58
 
Here's a positive update:

I purchased and received the Evolution 58 with the 201 carb. I'm running a custom header at 16 inches on an MTW RE2 tuned pipe with a Biella 24x10 prop. I'm getting 6400 static on the ground, the 24x10 is almost ripping in the air, it's perfect. The power curve, mid range/transition is excellent and its very quiet! I litterally installed set the needles and have been flying with 3 flips since day 1. The extra weight of the engine was advantageous to counter the weight of the long exhaust. I have to give it full props, I love it.

Fly hard!
