SH 28 P3 VS Dynamite 28 Big red. what's the difference?

[@blakelove4058]

Good info... Just purchased 2 of the Big Red Mach .28 from Horizon for $156 and some change for each..

[@thebug4046]

Nice! They are about 240$ each here

[@davelowets]

1:52.. The combustion chamber (or "burn room") is MUCH smaller in the P3 engine head button. That's where the compression increase for the 0% nitro came from.

[@thebug4046]

It was also machined by the previous owner who was running the same stuff and he was experimenting but yes you are right

[@ShadowOppsRC]

Sweet! I thought so cause got a used big red that all the internals are junk but block is good. Makes since because dynamite is a brand of sh.

[@thebug4046]

Yup! I love how interchangeable these engines are regardless of what people think about the company they're still really good that they've done that

[@davelowets]

@@thebug4046 I've always had good luck with the higher end SH engines. They're usually pretty strong too. The stock SH B-01 in my ages old G.S. Storm buggy was a RIPPER once I ported and polished the block, crank, and rod. It kept right up with some VERY expensive engines, and embarrassed a few guys who had those big buck motors. 😁 It lasted a HELL of a long time too.

You should make a video swapping the Big Red piston/sleeve into the SH to see how it runs.

[@thebug4046]

It will run the same as a big red haha it's already been done before as a rebuild upgrade for the SH P3. Just no video about it that i can find. You probably wouldn't be able to tell the difference on video. But I will see what I can do

[@revtech2917]

You should make a video on it. Since nobody has done it on video before, it would make for some good content.

[@thebug4046]

@@revtech2917 I will do it at some point or another. but you gonna keep in mind the parts cost here is really expensive this big red is completely worn out and doesn't run anymore otherwise I'd be using it. and the piston and sleeve replacement cost $200 here so I really don't feel like spending that just to make a video unless I can find one cheap enough. KZbin doesn't pay me a dime but I will see if I can put something together.

A Main has the SH .28 8 port piston and sleeve on back order but they are selling these for under 30.00 American dollars! that is a steal if you want to hop up a Dynamite Big Red or a SH 3 port .28. they all have the same bore and stroke.

I know this may seem like a dumb question but I’m sort of new to this stuff, but I’m considering rebuilding my 3.3 on my tmaxx a whole motor refresh with OS 11k carb new bearings est, or should I or exactly can I do big block conversion? What do you think ?

The big block tmaxx kits are no longer available. It's also a big pain in the ass to do it and you have to completely change and upgrade everything witch gets really expensive and annoying.

@@thebug4046 hey if you really want to blow people's mind.The .28 and .32 ofna force engines are the SH based engine.i took a .32 O.F. engine crankshaft and put it in A dynamite.28 and that changed the timing for it to be like a factory modified crankshaft!!

[@davelowets]

@@ofnaguycarlwatts8602 I'm very surprised that the windows in the cranks were even any different between the 2 engines to begin with. The Force engines are a lower line of SH engines, and they usually use as many of the same parts as possible between the various different engine models.

[@ofnaguycarlwatts8602]

@@davelowets I guess a better way to say it the Ofna Force.32 has a bigger gas window in crank than .28 Ofna engine So therefore if you put a .32 crankshaft in a .28 it's a lighter crankshaft and changes the timing so you could also put it a .28 dynamite engine as well .hope that helps someone.

[@williamoleary9330]

So I’m interested in maybe dropping one of these into either my LST or LST 2. The original engines in both are running great so maybe it will be a temporary upgrade deal. Can either of these work with a spin start? I hate pull starts so I’d only upgrade if either one of these could have a spin start mounted to it. Please let me know at your earliest convenience. Thanks

[@thebug4046]

I'm sure there is some kind of electric starter for it. But whatever you do do not try to start it with a drill on the starter shaft without the pull starter body because the shaft will pop out and it will smash the crank shaft and destroy the engine

Curious is it Chrome or is it nikasil.

Everybody out there have a good day

[@thebug4046]

Hey man so ABC is aluminum brass chrome 98% of these engines are chrome plating a lot of older stuff is nickel plated witch required extra castor oil for its film strength and piston sealing abilitys as for performance parts? The SH 28P8 piston and sleeve is and 8 port witch will replace your 6 port sleeve and aside from pipes and fuel that's about it for that engine performance wise. 🤘🏻💯🍻

No worries buds and Nikasill is a brand name it's a little different than the old nickel plating in the rc cars witch is really soft and you can scratch it pretty easily compared to Nikasil witch is really hard and you can't scratch it unless something really bad happens hahaha

Abn why is this even a thing anymore like really

It's cheaper and faster It's to produce and depending on where you live and your environmental standards a lot less toxic than chromium plating which is often quite nasty but it also makes for an engine that doesn't last as long but for the most part and today's dayne age cheap cheap cheap cheap
