After purchasing a LRP engine I couldn’t help but notice the likeness of the M26SS engine compared to the LRP engine. The first thing I noticed was the block. It looks like the same casting. The only real difference I can see is the cab is bigger on the LRP and the LRP has more ports.

I can’t help but wonder how the M26SS engine would perform if I drilled a few ports and replaced the carb with a bigger one...

What do you think?

IMO you would think that the inside of the crank case is different between the two of them. If you look thru the Engine forums ....[link=http://www.rcuniverse.com/forum/m_5226191/mpage_13/key_/tm.htm]Clicky[/link].... you should see some really modded sleeves but i have never seen anyone put a new "port" in a engines sleeve... honestly i wouldn't even bother with it. Im not even going to get into the whole "timing" thing[&:]

well considering Dynamite and LRP are owned by golden lion, most of there products are the same with differences.

The mach 26, mach 427, mach 28 etc are all dynamite engines.

Golden lion are XTM, SH, LRP, Nosram, Dynamite etc, there all the same company, ie why alot of these companies engines are the same just with different names stamped on the engine block and different cooling heads

Golden Lion do not own LRP, they produce some engines on behalf of LRP, but definately do not own them.

You need a digital mic and to take some measurement of the crank and rod journal and length to really see the differences... I predict by the 3/4 gallon mark, provided you are not running the stock pipe, the differences will be very apparent.

From the research I have done I have no doubt that I will be impressed. I guess I expected to see more differences than I did. It almost appeared that one company is making the blocks…?

Thanks for your input; I would hate to think I got caught up in some marketing strategy…

yes they are a golden lion motor mate. Do some research. The Nosram 28 is the same as a spec 3

The SH 28 prosepec is the same motor as the LRP spec 2. ETC, if they were not the same company then why are there motors exactly the same just with a diff cooling head and insignia on the block. Most companies are a golden lion brand

I don't think that they are the same engine might have the same casting block but the LRP sleve is so not the same and I would think the crank is differant. I have the LRP in my mgt and it runs real strong and can take my LST2.

If you're talking to me, I know the LRP is a golden lion engine, as I said in my post. You made the claim that Golden Lion OWN LRP.....WRONG.....Maybe you better do some research!

Jeez just because the block id the same don't make it the same engine, look at the automotive world, the chevvy v8 blocks and the rover v8 block have been used by many different companies yet some make 200bhp some make 1000bhp. The sleeve design and timing are what makes these things work a slight difference here can make masses of difference. Would I be right in saying that out of the golden lion blocked engines the LRP spec 3 is the most powerfull? would be cool to see a list comparing the different engines as some are harder to find in the UK and others are cheap and easy to find.

Now I am really disappointed. I just sat down to install the motor mount on my new Dynamite mach 28. Before I started I compared the cylinder sleeve to the stock M26SS engine. What a disappointment, everything is the same except for the intake port. THE DYNAMITE ENGINE IS SMALLER BY ONE MILIMITER… And get this, the Dynamite mach 28 has a bigger carb (go figure). I never clamed to be a rocket scientist but I can see theses engines have a lot in common and the biggest difference is the pretty cooling head that catches everyone’s eye.

So for the most part if you have the ability I think you could perform some porting work on your stock engine and save some money. I am going to try this with my M26SS engine, here is the plan:
-M26SS engine
-Dynamite mach 28 carb
-LRP Porting
I will let you know how it turns out!

NOTE: Please understand that I am not in any way taking a whack at the LRP engine or any other engine mentioned. I am sure I will be very happy with the LRP engine. I am just wondering if porting modifications can be done to a stock engine to make it perform close to the so called power house engines.

I beleive the crank stroke is different between the Mach 28 and mach 26....

Thanks!

I did not think of that. I will let you know...

me and my mate compared my Mach 427 and his LRP spec 3 28, and the port, crank, rod everything basically are identicle, except the LRP has a the larger bore ie; mach 427 is a 26 and the LRP is a 28. Found that pretty cool

M26SS BLOCK
M26SS PISTON
M26SS SLEVE
MACH HEAD
MACH CARB
PORTING

I am confused are we comparing the Mach 28 to the mach 26 or the mach 26 to the LRP?

I am comparing them all.

dont try to do your own porting, it can totally screw up your engine. you have to know how far the piston travels up and down, when which valves need to be open and when to be closed and how long they need to stay open.also drilling them might make the sleeve less smooth, and if the piston scrapes against something it could wear away and you would loose compression. these engines operate under very igh tolerances and you need to know a lot about them before modding them yourself.

drag racer,

I got it! Just cleaned up some corners you know, smoothed things out. I do agree with you about the timing thing, “no touchey”.

Thanks for the heads up!

Its easy to port a motor, just dont change the timing of the ports. I dont enlargen my ports, as this changes timing, but i do smooth out the flow and tiger claw the intake and boost ports.

This is the first motor i did, its a OS15CV, i stuffed up in a few areas, ie turbo cut the crank the wrong way, and a few of my tiger claw cuts are facing the wrong way, as the intake ports are meant to face away from the exaust port and the boost port straight at the plug. But anyway heres a few pics, it goes ALOT harder than it ever did though

Turbo cut crank


Opened crank (pretty rough i was rushing lol)


1st intake


2nd intake


And boost port


As u can see its abit rough but it works pretty good. Its a half worn motor so i wasnt worried it if popped and never ran again lol
