You can be the best tuner in the world and if your way over shimmed at altitude your gona run hot, have no power, and chase a tune all day. There were a good number of pro drivers this year that really struggled with their engines at Nationals here and the altitude at that track is 6,500 feet. It's not like any of those pros are bad tuners, so it's not as easy as just tuning it to make good power.

I was asking because I was hoping someone in here has actually been running a GO engine at altitude, and has tested different things. I mean it could be as simple as running 40-50% nitro or it could be pulling a head shim, running a cooler plug and going to 20%.

I remember last year at nats in Colorado everybody was having power issues. Most people ran either 40 or 50% nitro and decreased deck height to compensate. That was every brand of motor. I am glad I live at 14 feet above sea level cause my tuning skills would not make it up there.

Well I do not run GO Engines, I do engine breakins, bearing swaps, engine rebuilds, and sleeve pinches for local racers here in Colorado. Because of this many of these people come to me for tuning help at the track or suggestions on engines for their kids. Since GO's are a budget engine it is naturally one of the engines people ask about and pick up without much knowledge. So Sorry I am not gona do the testing of these things, if nobody has anything they know is working well I will just recommend other budget engines when people ask. Sorry for the trouble.

Chris- I just talked to puddin. He was working with Drake and they ended up leaving the stock shim setup, but with 40%. That's one copper and one aluminum shim. If you feel like you're not getting the answers here or just smart ass comments, please feel free to ask us at our email addresses below.
