best break in method

[Tachyon]

I just broke in a new engine last weekend. I already had a tune for the setup so I could get on it without worrying about running lean.

I first let the car warm up to operating temperature, then I did repeated full-load, full-throttle 3rd gear accelerations followed by engine breaking in the same gear (18 psi). I did this for 20 minutes and then brought the car back for systems check. I've since then put about 300 miles on the engine and it feels very very crisp. I need to do a compression check, but will probably put another 500 miles on it before doing so.

I like to give the engine lots of load in the initial 20 miles or so. After that, just normal driving (which is quite heavy (weekend toy))

GL with your engine.
