Timing key
Have the key in 3 M1000 sleds, ran 8lbs last year with RK Tech turbo head on straight pump and pulled the pistons this year (after 4 yrs) and looked like brand new still.
Second sled fresh built last year with WTA I/C and 3076 turbo and PCV and stock head cut .020 and ran 8-12 lbs on 50/50 av/premium and no issues.
3rd sled this year put together a bunch of used parts with a 500 mile crate motor (left stock), used BD turbo kit with 3071, Attitude controller, 3degree BD key and run straight AV at 12 lbs and no issues. Has a 174x2.5 CE. Ran uphill snow drags this past weekend at 5500 ft and only competition I had was a 300 Hp MCexpress Nytro with a 3" track running race and we were neck and neck off the line and all the way up the hill. I won 1 race and he won 1 race and I blew a belt on 3rd race. Other M1t, Dealers M1100 with Hijacker and other 800 turbos were not even remotely close.
With the 1000 I have noticed very little difference with key other than I can run cheaper easier (here) to get fuel. This is running at 5-9000 ft.
