How exactly do you gear a drifter? It has the stock gears, 22 pinion and I'm not sure on the spur gear.

I ran it last night, it was a little cooler outside. It barely broke 155. The problem is that it doesn't get much airflow because its drifting. If I put a fan on it and it is cooling it even when I stop, it should keep it down. Running it in the evenings also helps.
