It is difficult to answer that question 100%. I would start around 60mm myself and work from there. My R40 loves between 60-58mm at my local track.

Leaning a motor will always increase heat. Because you are taking away the cooling agent , aka the fuel.

When you richen , increase the amount of fuel in the mixture. You cool the engine more by allowing more liquid to enter the chamber at the time of combustion.

The best way to run a motor is to find the optimum tuning point and richen a little to allow the most power and proper cooling. You should also watch your exhaust. If smoke isnt coming out on throttle then your possibly running to hot.

Hope that makes sense. I will post a guide to what you are supposed to do when you are faced with different temperatures , humidities and so on.

Nitro eats tires like crazy... I'm only able to run two races with my nitro on a set of tires while on my electric I can run four or so.

I let the track wear down the tires for me. There is no point in losing those 4mm when the first race is usually just a practice or warm up. I run the practice and warm up on full size tires then true them down to the lowest tire's diameter.

Tire wearing also depends on car setup, shore, and how you run them. I've had runs for over 30minutes where the foams hardly worn down. That constant high speed runs back and forth and putting down 5-6tanks of fuel. I run 40 Shore GRPs and let them dry out in the air so they last longer. Traction is still great.

Welp, gonna get my R40 and MRX4 to the track on fathers day unless my friend has different plans. Regg are you gonna be there?

Also depends on the track... I run on a parking lot surface which is very agressive.

Nana. Looks like we have the same motor. Do you know exactly what model number or engine name you have? Also whats your specifications if you know it.

As from what I can tell mine is a 5 port turbo , with the words race and s5 at top. But when looking up info the s5 is designated to be a non-turbo. So I wonder if a turbo model is the t5 race model.

I believe the model number is rs12t5s1

I know our engines are very hard to find and to also find any info on them. Do you have the box still, what does it say on the side. Also do you have the manual and could you show me a picture of your middle speed needle cause im sure mine has been touched from the factory.

Id be really appreciative, your the only person after months of searching that Ive ever seen with it. Funny enough you just so happen to have an r40 and post here....Thanks.

I think with a different picture that would have looked really cool. But its def funny that face.

The theory was humor, I thought he made it a little too big. But he was going for the "wearing the helmet" look, that's why it's just my eyes and nose. Next time we're putting a sedan body together, we're putting the whole face on, and adding family and friends and pets as well(my girl will be ridding shotgun, with the inlaws in the back seat, all with the scared crappless looks). It's an Escudo...should look pretty funny. I got it because it looked like an exadurated rice rocket from high school land...

I spent most of last night tearing down and reassembling my r40.. This was the first time I had done this and have gone through about a gallon of fuel..
The first thing I noticed was how heavy the axle and bones are.. its like holding a piece of lead... anyone tried the 3racing axle and bones? I found them at rcmart and they look pretty good.. The shocks were only slightly low on oil and the front diff had been leaking leaving me nice gooey mess.. this I was aware of and have cleaned a few times already.. this time I took the diff apart and cleaned it up, refilled it, and it seems to not be leaking anymore but only time will tell. all the bearings are like new again after some motor spray and wd-40..
now I just have to wait for the rain to go away to dirty it up again....
