My GT break in is coming along, think I'm on the 6'th tank now starting to lean a little, just started shifting into second gear - it seems to keep up with others even though blowing smoke on the straight. I've left the bottom rich and just leaning the top needle at this point. I haven't pushed the engine hard as yet but the race is this weekend. Plan to run as is for a couple more tanks before race tune. Its running just over 200 F about 220-230 at empty tank. Any suggestions on that temp, needle settings etc? It's about 85 deg here in Houston, not very humid yet. Thx
The engine will need a good number of additional tanks to become completely free, I usually run about 20 tanks through it before race tuning it.
Even you can still feel the engine getting stuck at TDC, you can race it, but give it a couple laps to get to temperature before you give it full throttle. For the moment, keep the engine running at that temperature. What nitro percentage are you running, and what plug? My prefered settings are 25%, deck height increased by 0,10mm, OS RP8 plug.
