Hi people I'm goin to get a 21 engine for my 1/8 ic on road just wanted to know the best way of running engine in.Is it better to run in on track?

Thanks people

It would definitely be better to do it on a track, when there are little to no people on it. Just keep temps up, nice and rich and go through the rev ranges for about 8 tanks, but this varies from person to person.

There are 1001 topics about running in, search them and read them all to see that all methodes will work.....

The heatcycle is the most common

We have several heads to control the heat, you can start with removing the head and start running rich with only the buttonhead on 100 degrees celcius and mount the head back again after 2 or 3 tanks.

i start off by putting 2-3 drops of after run oil thru the button head, then the move piston up and down back to bdc..next i use the heat gun til it reach 100-120 degrees then start it up and run it rich but the the first tank i let it idle on the ground after that next tanks then i do figure 8's in a parking lot

This is how we do it.

Thats how I did my RB T10, but only recently I realised how important it is to keep the temps up.

My style :

1. I put another 0.30mm shim to lessen the compression

2. 5 tanks break in on the bench, and keep temperatures around 80 - 90 C

3. 5 tanks break in on the circuit, and start closing the hsn on the last two tanks.

4. I remove the shim after two race meeting.

Actually I would run it at track but With People so you can ask around for tips and assistance! Good luck

Thanks for your help when u say break in on bench do u just keep car idle or slightly rev throttle as its on bench this is what I don't understand.

Thanks

Bench means on a stand/off the ground! Let it sit at idle no need to have to keep remote on once you everything is idling normal and smooth

Nothing worse than hearing a piston screech against the liner, you run a richer mix so higher revs needed to keep the engine temperature up enough to prevent the screeching.

The engine thread has sticky break in tips.. read them first.

So give it airflow too. Why many put props on.
