RE: 10 engine comparason, side by side
I gave it slightly higher on torque, which to be fair, was actually in the midrange area... The overall power section I tried to think of like the torque-curve rather than a peak on a graph. My S25's torque curve was longer an flatter.
Some of that may come from bias against that engine (the 28) and it's predecessor Toki/Infinity/Fantom 27... Both were PITAs that quickly lost compression and even before that, were hard to tune. I also had a buddy with one who needed help, so it was like a PITA that came back to haunt.... So I can't say I'm without prejudice there.
Some things that made that engine somewhat tolerable and tuneable were (outside the obvious like NO AIR LEAKS ANYWHERE, especially tru for this mill) a tuned pipe that provided max pressure back to the fuel system. I had the best luck with THS, but then, I have liked their pipes best on most of my big-blocks. The ribbed pipe is a no-no with this engine. Even if it DID provide adequate fuel pressure (doesn't though) it's not matched to the powerband of that engine. The stock tank adds to the headache with it. 30% race blended fuel and medium plug on the 27, and a cold turbo plug on the 28 with 30% race fuel. It ran a bit cooler as well as tuned a bit easier when I moved form 20% ODonnell to 30% ODonnell with each of these.
Overall though, they are wretched things, and I wish I had bought other engines.

Of the listed engines that I own common to Polar_Bus, I would have to say that his feedback on most are VERY close to what I have experienced myself. These engines kind of pile up on on you after awhile. If anyone was intrested I could make a list of the smallblock engines I have owned in the same fashion. I started to add an entry to this post when I first saw it, but was distracted along the way.
Note that this is not the same as PB's list, even though 6 of the engines are the same.
Collari .30: Torque 5, O/P 4.75, Tuneability 3, R/R 3.5
SH .28: Torque 4, O/P 4, Tuneability 4.75, R/R 5
Nova/Rex/Top 3port .28: Torque 4.75, O/P 5, Tuneability 3.5, R/R 3.5
Infinity/Diablo/Wasp .28: Torque 3.5, O/P 2.5, Tuneability 2, R/R 2
FantomRacing/Infinity .27: Torque 3.3, O/P 2.5, Tuneability 2.3, R/R 2.25
Wasp .26: Torque 3.75, O/P 4, Tuneability 3.5, R/R 4
Picco .26: Torque 3.75, O/P 4, Tuneability 3.5, R/R 2
Picco/WerksRacing .27: Torque 4, O/P 4.5, Tuneability 4, R/R 4
HPI S25: Torque 3, O/P 3, Tuneability 3, R/R 4
HPI .21: Torque 2.75, O/P 3, Tuneability 4.5, R/R 5
Ofna Force 25 : Torque 3, O/P 3.25, Tuneability 3.5, R/R 4
Ofna Force 26 : Torque 3.2, O/P 3.4, Tuneability 4.25, R/R 4
Ofna 21 hyper 8port : Torque 3, O/P 3.25, Tuneability 5, R/R 5
....and thanks to Polar_Bus for taking the time to write out his experience for the benefit of other readers/users.

Like I said, and now (we) including Frost, the Wasp .28 is a total worthless terd of an engine. I am 100% sure if you lined up an S25, and a Wasp .28 side by side. They would be about equall, maybe even the S25 winning a race. My Wasp .28 had poor torque off the bottom, and very flat top end. The S25 was a very well rounded engine as far as good power output, especially good power for new nitro guys learning how to drive. Sorry, but your erxperiences with the Wasp .28 are a single positive claim, I hear far more claims of totally negitive feedback on the Wasp .28 in generall.

I also said the engine was very hard to tune and doesn't hold a tune and overheated.
I don't know how you saw this as positive.

RE: 10 engine comparason, side by side
I just bought a savage 21 from a friend who should stay with eletric. I bought it for $150.00
I have some extra cash and heard the 21 is hard to tune. My frien said he cant get it to start.
He has one hour of run time on it.My question is is the 21 a p.o.s and should i buy a new engine
or is he just an idiot. If i should buy a new engine which one.

Well, if you have extra money that you want to spend on a new engine, you may want to look into getting a bigger engine(.25 or bigger).

RE: 10 engine comparason, side by side
in reply to bmauney the rex .28 is worth the money.its a direct bolt in,aside from alittle massaging of the engine mounts,(it has a slightly wide bottom case)a tiger drive is a must though.exellent power on 30%.just to give you an idea we had to buy new rims and tires because it was torking them so hard it split the wheels at the beads,and after that was fixed it stripped the wheel hubs.spins way faster than the stock motor,probably 40,000rpm and the truck WILL hit close to 50mph.

RE: 10 engine comparason, side by side
I got a STS .28 but I run it in my Hyper 7. Solid engine that I never really have to touch the needles on. Have to be careful though because the PS cord is a little short. The buggy really flies though(not literally.) My favorite engine is actually my Mach .26. Not a great fit in the Savage because of the large PS but it is sooo consistent. Probably not as powerful but I'll take the dependability. Those are the only two engines I've had besides the stocker though so my experience is somewhat limited.

Hi Polar_Bus,
may I know which SH .28 model did you use?
I kinda read it from somewhere that there are a few batches out there..

RE: 10 engine comparason, side by side
I'm a newb to the hobby, have a Savage 25, and the more I read about engines, the more it sounds like the LRP Z28 is the way to go - at least for me. "For me" meaning that it needs to score high on tuneability and reliability, as well as having a worthwhile power increase over the NS 25(and of course not being too crazy expensive)... So, given what I've read and what(admittedly little) I know, and taking into account my particular situation.., it sounds like the main options for a first time upgrade are either the LRP Z28 or the NS K4.6....
Am I right?

RE: 10 engine comparason, side by side
Is this the same as the sh 28 engine that was mentioned earlier?

RE: 10 engine comparason, side by side
Polar and Frost , don't you think it's time you guys go shopping for new engines as your engine list is becoming a bit old [8D]
here are some engines which are not on the list : Sure Fire .32 , Collari .32 , O.S. 30 , LRP Z.28R , STS .28 , WASP .28 PRO ( Not Toki ) , Picco .27
I wonder which one will you guys choose as your next new engine ?

I have over $1500 tied up in engines ALONE, I am not going to go on a buying frenzy just to satisfy newbie engine questions. (Nobody really cares about my info anyway) I recieved FAR more idiots argueing with me, that guys complimenting my comparison. But bottom line is I will purchase an engine in the spring. I just have to keep reading for CREDIBLE feedback, to help in my decision. I am leaning towards either the OS .30, or a real high end REX .28 . I want to see if those "Spaghetti" engines really match up the the escallated cost.

RE: 10 engine comparason, side by side
Are STS's really that good? They're cheap, right? But are they direct drop-ins, and as easy to tune/reliable? How do they compare to a K4.6 and the LRP?

I too have been thinking about one of those.
