I know for sure that SPEC 3 is better (botton end, mid and high end power) than SPEC 2 I race LRP engines since the spec 1
the differences that i see lrp spec 2 to spec 3 are;

the top of the sleeve is longer ,to compensate, the burning room is also longer (inside ) to maintain same clearence- same head shims
the cranckshaft has black anodized on some parts with minor modifications

I do not know about timing if had changed

the conrod has two small risks on inside botton side like megas

the coolong head is little diferent

and back plate also

Maybe i forgot something but......

Thanks

Fabian

It's Ok Fabian, since i have RC Shop and distribution of several brands I have to be informed of everything, and I have good sources..jejejeje

I've had Picco engines since the old side exhaust and currently I have a JL Red Dot and a Picco Evo2 Edo Tuned, so I know a bit there and here about Picco engines...jejejeje...they are crazy fast.

From what you describe of the LRP Spec3 it seems to have same parts as above engines I have.... maybe difference is in timings and silicone ramp on cranks of engines I have, also my Edo has backplate with dished-in recess aligned with discharge exit of crank hole, also the crank bore is bigger than the one on the JL.

Please do post pictures on LRP forum, I don't want to abuse on Murnan's thread, which is meant to talk about his engines.

On a side note. We're having a big race here in Peru on April, with guys from Chile, Ecuador, Colombia......If you are interested in coming send me a PM and I'll fill you in with details.

The Modified JLR Red Dot is in stock, as well as the modified Ninja T01A. We also have the stock version of each engine if you are scared. :sneaky: Ninja pipes are here too. :tire: :tire: :tire:

Has anyone run Byron fuel with the Murnan Modified CRF, according to Nano in the CRF engine thread it's not the best fuel for performance, but my choices are limited, my only other option to Byron is Weston ProSynth which is readily available.

Any feedback would be greatly appreciated.

impalabob64,

Thanks for the feedback, I've always run Tornado but can't get it for love nor money locally now and the shipping costs are almost as much as the fuel.

The local model shop only sell Model Technics, not sure what there new Sical blend is like, I know I can get Weston ProSynth a short drive away but never had any experience with their fuel which leaves me in a dilemma, your experience with Byron backs up Nano's view. :confused: :confused:

Regards, Mark

fantini
 
Hi uriah I have a new in box fantini .21.
I am going to use it for drag racing.
Is there any improvements you can make to this engine if I send it to you?
What would you recommend be done to it?
How much and how long would it take?

quietstorm76 03-09-2007 03:10 PM

I run Bryon's in my Murnan. It's good fuel, very safe but I've ran other fuels that make more power. I chose to run Byrons because I can get it any time I need it.

Diesel Racer 03-09-2007 10:27 PM

Thanks for the info quietstorm76, I assume that Byron's has a slightly higher oil content to say Tornado?

Thanks for the review. :)

- How does the Ninja pipe compare to the Skyline pipe?

- Is your conventional break-in similar to what Mike S. is doing? If not, what are you doing different?

Thanks Uriah! :)

7th tank 1/2 throttle
8th tank full throttle (make sure engine is running rich)
9th tank 1/2 throttle
10th tank 1/4 throttle

Put the engine in the car and run two or three tanks at a rich setting on the track and then it will be o.k to lean it out.

Hi. I will try the Skyline pipe today. I used the similar break in to the one Mike posted. Works fine for me. Well time to go pound the Ninja's at the track. Stay tuned for a report!
