And my engines always seem to run at 270-280. I'm now running a Collari B7 and I already have about a gallon and a half through it and it's still waking up and giving me more power every time it's out.
I didn't say that this is the method that should be used,I simply figured that while we were all on the discussion of engine break in methods I would provide a link with some info to another method of break in.
personally this is how I was taught to break in an engine and this is how I've done it on all my engines to date (with great success I might add).
the first tank I run through at idle on factroy settings,along the way I measure temp and assure that I'm hitting about 200-210F (if needed I'll make some adjustments to both the LSN and HSN to assure I reach that temp),when the first tank is done I turn the piston to BDC and let it cool for about 10 mins.next tank I let it warm up for a min,then I drive around while slowly throttling it to about 1/4 to under 1/2 throttle and back to idle.basicly I'm slowly accelerating and decelerating,I do this for the second tank again checking that I'm running just over 200.again piston at BDC and cool ten mins.3rd tank I drive around again this time as I throttle up to about 1/4 or slightly more I hold it for 2 seconds before decelrating,I usually just count one-one thousand,two-one thousand and release.again I'm just driving around throttling up and down.for the 4th tank it's the same but I count to 3 and get more to about 1/2 throttle.5th tank I start leaning out a little more untill I'm around 220-230 and drive just drive around getting more speed and time on the throttle but still not going full out,usually around 3/4 throttle runs.from then on I just slowly keep tuning and driving a little harder untill I've put about 7-8 tanks through it.
is it the best way,maybe, maybe not,it's one of those subjects where you'll get answers according to each person's preference and how they've learned.I just know that this has always worked well for me,I have a TT 21 from my MGT that has about 6-7 gallons through it and still runs very strong,I'm sure I can easily get another 3 or more gallons through it.in the case of high priced engines or engines bought from a retailer that offers some kind of warranty,I would just go with what they reccomend only to avoid any warranty issues.but hey that's just my opinion
