Hey guys, I've heard that the .26 is a better engine then the .28. Does anybody have any ideas about the two. I'm debating on getting one of these, but I'm not sure which one.
Thanks
Thanks

I can't help you bet i read this thread and went to check out the .26, cuz i sisnt even know that wasp made a .26, and i noticed that the .26 costs more than the .28 thats kinda weird. I'm sure they are both great engines, iv only heard things on the .28 and they were very posative. good luck.

I never had a .26, but man, my Wasp .28 is a BEAST. I absolutely love my Wasp .28 and would definetly reccomend it, but I can't compare it to the .26.

I've never had a Problem. Set it and forget it is how its been for me. Maybe a tweak every now and then but other than that its run flawless since I've had it. Wheelies my savage like no other...

The .26 is Picco based as the .28 is not, that is why its more expensive. I recommend the .26 because of this. But if you plan on racing, stay with .21 sized engines -- Rules.
With the .26, look at spending 1/2 gallon of fuel for break-in. Thats when the real power appears. Tuning it is a set and forget, no problems. After running 6 gallons of 30% through mine, it is still difficult to turn over by hand, great compression.

My previous opinnion on it is the 26 is better than the 28. It's hard to say which one but for reliability the 26 is better. Once you get to know the 26 it's consistent but I've read many people can't get a tune on the 28. The 26 is definately a more robust engine vs the 28 it's got a bigger rod journal, rear main bearing, and block(larger intake runners, need to breath to make power). Internally the 26 is basic and the 28 has flute cut on the crank, knife edge rod and a turbo head. The one-way bearing on the 26 is easily broken but the 28 the disc and shaft is spinning at the same rpm as the engine. I don't think the 28 can make power in the upper rev range because the intake runners in the block are too small and restrictive that's not cut all the way through to rod cutout impeding flow even more where as the 26 are wide open but the lack of cuts on the 26 limits its ability to make power.
My home port/polish/hacked up block 28 smokes the port/polish/increased exhaust port duration 26 but since I've really hacked up the block to make bigger intake runners there's a good chance it'll break (I don't much like this engine anyway) when I crash just the right way. Both engines have a smooth progressive power delivery with the 28 better in the topend than the 26.
If all you want is power then go for the 28 but it does eat more fuel than the 26. Many people have had the 26 for a long time and can vouch for its durability. I've never run the 28 in stock form so can't say how the power delivery is but the 26 is all or nothing with very little throttle control and no upper mid and topend. Many people disagree about the throttle control and powerband of the 26. I think they haven't had much expeirience with other engines. I know the 26 was my first engine upgrade and I thought the same until I got other engines.
My choice is still the 26.

the 26 gets my vote too. greater durability and smoother power than the 28. in fact the 28 is just a rebadged fantom right? I've known a few guys who ran the fantom 21's and they really sucked ass. there are only two things to watch for with the 26- one way bearing and con rod. being picco based the rod should be replaced after 2-3 gallons and of course have a spare one way on hand at all times.
at about $160 the 26 is definately the way to go.

Well, I can say that my .28 provides very smoothe power all the way up to the 42,800 mark, or whatever I can actually kit lol. It provides amazing low end and high end power for me. Tuning has been a breeze and I have not had a single problem with it thus far, about a gallon. My vote is for the .28 but like I said, I have never run the .26 so I can't compare it.

Ditto, what AC48 said. The Wasp .28 has been both, reliable & powerful. But at the same time, I haven't been head-to-head with the Wasp .26, so my opinion is biased.

My local hobby shop stopped carying the .28 because they were junk engines. The kept breaking on the people that bought them. On the price fact it is because the .26 is made in italy, while the .28 is in japan also hence the quality difference
did you tach the 42,800 rpm under load on the wasp28? Or does just feel like 42,800 because it doesn't spin any faster or there's no more power? Yah, sure the wasp26 says it goto 38,000 rpm but it makes less than 1 hp after 28,000 rpm and the engine won't pull any revs after 30,000. So what is the max 30,000 loaded or 38,0000 under no load.
I don't doubt the wasp28 has more power than the 26. It probably does but the 26 has more going for it. It's a better built engine and from what I can see from having both apart the 26 is more durable than the 28. Which will be more dependable a more powerful engine built weaker or a slightly less powerful engine built stronger. If you ever decide to port/polish and/or have it modified to make more power which engine do you think will stay together and/or not wear out fast.
I don't have faith in my modified wasp28 lasting too long sure it makes crap loads of power but the bottom end is weak. For example whren grinding the crank it took alot more time to take material off the 26 crank than the 28 which means it's harder and stronger. Under increasing loads the 28 crank will fail (snap) before the 26 crank will.

I don't know exactly how much RPMs the .28 will hit, I just said 42,800 because thats what it is rated at.
The low end on my .28 is insane, its hard to keep the wheels down with 18/49 gearing on my savage.
I'm not doubting the .26, but I'm definetely not regretting getting the .28.

I have no experience with the Wasp 28 but I do have an Ofna Picco 26 in my Savage. The Ofna Picco 26 is the same motor was the Wasp 26.
My Picco 26 makes explosive power and it runs great. I am running it with the optional 9mm carb insert and the optional black LSN. It starts immediately hot or cold, never stalls, runs clean with no hesitation, and runs very cool. Even with very tall 18/49 top speed (numerically low) gearing it will easily lift a big power wheelie from a roll. Some people say that this motor’s power delivery is just on/off with no part throttle. This is not the case at all.
I posted a video on this page that shows the part throttle performance:
