this engine is INSANE!

I am on my 6th tank, running at break in settings very rich, and I can keep up with tuned .12TZs, I can't wait till this engine is broken in and tuned cause I know it will RIP!

thanks
I have a X-Dyno on order from BK. I will be more then happy to test the JLR when the dyno arrives. The dyno should be here in a month or a little more... I'll deffinatly post up some results.

Default JL POWER

Can anyone tell me the temp this motor likes to be?
And the bottom needle likes to be rich instead of lean?

Around 200 F to 230 F degrees (max). As long as you see smoke.

this engine is easily making peak hp of about 1.8- 2.0 hp.

Not on a SAE corrected dyno such as a X-Dyno... But i would think it would hit around 1hp or so if i had to take a "guess". The engine seems very strong! I'll soon know for sure.

Since we all know these JLR engines are Picco based engines, so as the LRP engines, I thought it might interest all to know the results of the LRP engine on the dyno, which can give us pretty much an idea of what the JLR has in terms of powerand considering that the JLR is more close the LRP spec.3 I would say that peak HP might be closer to 1.13hp

AFM

LRP Z.12R Team Spec.2 ,on Xtreme RC Car Magazine X-DYNO test:

This Italian Picco based engine was made to the specifications set forth by LRP.

Performance
We used our Serpent break-in bench to get the engine prepped for dyno pulls. One thing I noticed before even running the engine was that it didn’t have the typical amount of pinch at TDC that I’ve felt in some engines. Pinch used to be considered a good thing, but having too much during break-in stresses the con rod and generally isn’t good for the engine at all. The LRP had just the right amount to where it wouldn’t stress the rod, and after 7 tanks on the bench and getting it up to operating temps, I was ready to get it on the X-Dyno.

We switched our display this month to use the higher resolution of torque readings (now in oz.-in.) and initially I was confused by the look of the graph. After 7 pulls and tuning the engine I clicked the graph function and up came a number I wasn’t prepared for. The engine had set one of the highest mark in peak horsepower for the class, displaying a staggering 1.11 HP @34,500 RPM and an equally impressive 32.46 oz.–in. @ 34,250 RPM and spun to a dizzying 41,250 RPM.* I had to double and triple check all the settings to see if I had something wrong, and after verifying the settings it was official. Tuning was also very easy, with changes making improvements to the performance but not to the point of 1-hour changes causing it to go extremely lean or rich. That’s a very good thing to have when tuning on the track.
The power delivery of this engine is very peaky, something that’s more typical in .12s and really can’t be seen as a negative. This means that to keep the engine delivering that killer power you’re going to have to make sure that you’re in the upper RPM of the engine, and not past the useful range because it also has a steep drop off after peak. Keeping that engine revving will result in some top-notch acceleration on the track, and depending on the pipe used you could tune it a little broader. but our MSR pipe has proven to put out some of the best useable power we’ve seen.

* Specification on 30% Nitro fuel used, MSR (Mugen./Shimo P1002 pipe and header)

X-Dyno Horsepower vs. Claimed Horsepower
You may have noticed that X-Dyno power data doesn’t always match up with manufacturers’ claimed horsepower and torque figures. We attribute this discrepancy to the fact that many manufacturers publish theoretical horsepower and torque figures based on rough estimates rather than actual dyno data, or that a manufacturer’s data collection protocol doesn’t match our own. The X-Dyno calculates horsepower using known mathematical formulas and precise physical data measurement.
