Large tracks may require an extra 0.10mm shim to reach higher top speed and improved fuel consumption, but this will decrease acceleration slightly.

TURBO COLD GLOW-PLUGS to use when humidity is below 70%
P5TC hot filament
P6TC medium filament
P7TC cold filament

P5TH hot filament
P6TH medium filament
P7TH cold filament

The filament number will depend on the ambient temperature. Colder use hoter filament. Hotter use colder filament.

Much needed info. Thanks AFM.

1. I guess you haven't seen this motor in action... 2. You don't go to the track much and see what the real racers are using now... 3. You don't go to any of the major races in the US or read what's winning the major races and placing the top drivers in the A-main... For the most Bang for the Buck... The JLR is must have... Not trying to blast your posts, but listen to how you sound... This motor is a Monster on the track when tuned right and matched with the right pipe and header... Either believe what the top drivers are saying, go see one in action or keep using what you're using since you think JLR translates to being slow... .02

I am curious to know how high above sea level you have been using your engine, AFM.

I am not suggesting altitude will make it a bad engine. Not at all!! I would only like to know since many places in Peru are extremely high!!

Thanks!!

Eventhough Peru has cities at altidudes as high as 3,200 mts (Cuzco), I've only run engines in Arequipa at 2,400mts, and the best engine I've run at that altitude is the OS TZ.

Our only serious track is located in Lima (sea level), see our association's web site www.apercar.com, and after every race results of last year's there ar lost of pictures.

Jokes aside, the latest Picco Evo3 is not even for sale yet, so the JLR is based on top Picco available engine, and I wouldn't be wrong to say that soon after the Evo3 is released there will be a JLR II or something like that....constant evolution my friend....so just rip the tracks with the current one......by the time you can handle its power, a faster version may be available.....jejejejeje

How do you think the JLR will perform at 2400 mts?

Thanks!

With the proper carb tuning, shiming and pipe it should work fine...it has a lot of torque which is good for high altitude. Lets see if in the near future we can organize a race in Arequipa to try it out.

Wow, they even have a Murnan Modified JLR Red Dot!!! If the original can hang with any motor out how much faster is Murnans? I have two motors, but would still like the original JLR to use.

I plan on getting a JL Red Dot soon, but a friend of mine was telling me that I should change the rod after break-in. Does anyone have any feedback on this? Is this something I should worry about?

No you don't need to do that, the rod is strong enough to last up to 5 gallons. It's best to replace the Rod every 4 to 5 gallons assuming it was never abused.

But if you want to play it safe, replace it every 2 gallons, specially if you have abused it.
