Car has been running great lately, weather getting colder. Today, took it out, first time run since Wed. last week. Got on it just a bit at a few stop signs, all well, boost was 5 to 10lbs but pulling hard due to cooler temps. Then, from a roll of about 25 mph, hit it pretty hard, not full throttle, but maybe 3/4 boost probably hit 16-17, I say probably because I was passing a car on a slight curve and did not want to look away from the road. All of a sudden heard a knock, looked at scan master, retard was 22 let off the gas, went to 19 then 17 then to 12 to 7 to 5 or 6 at idle. Car has has a knock now oil pressure is fine, temp is good.
Where do I start? Last time I had a tap, it was a collapsed lifter, this is not a tap, but a knock knock.
Car has the following:
20K on new motor. Has Champion heads, 216/216 cam, 70 series turbo and plenum, as well as front mount. 50lb injectors and SMC kit. Was getting ready to tune for the Alchy is why the boost might have hit 17, usually only go to 15. Today was going to be the day I worked it up with the alchy kit. Kit did not turn on so I do not think the boost went too high, probably not past 12 as previously today, 5 lbs was pulling real hard, and this was not nearly as hard.
Where to start? All input outside of selling it is appreciated.
Not what I had hoped for before the holidays.
