Breaking in new motor. Break in w/ Alky or Not

[87WE4BOOSTED]

Alright guys I’m getting ready to order a 6.0 Turbo Tweak Chip for my new combo. Should I order two chips? One chip set up for Alky and one chip set up for no alky? I’m thinking I should break the new motor in on 13~15 psi on 93 Octane without Alky. 93 octane is the lowest octane the car will see. When I get a handle on this tune I can turn the wic up slowly and move to the alky chip. What do you guys think? Please help as I don’t want to hurt anything.:redface:

"Break-in" is done after the first 1 hr of driving... Turn the boost down to 93 level, leave the alky off, and drive it. Once you have a few miles on it, change the oil, cut the filter open, check everything over, and start tuning... Done deal.

Steve, it's good to hear that you are ready to get onto the street. Take it easy at first, then enjoy it later.

I logged about 600 miles in the 95-100* heat of this past summer with mine set at 10# of boost. I made a 2 hour trip to a car show and then back 2 hours on the hottest day of the summer. Changed the oil and filter and started dialing it in. Then I began to lean on it a couple of weeks prior to the Nats.

Listen to Chuck. The only thing that needs breaking in is the piston rings. (assuming you are running a roller cam, if not, the cam lobe to lifter face also needs breaking in) I just start the engine, run it at 1800 RPM for about 20 mins. Then drain oil and cut filter and check for debris. Then change oil/filter and start it up and let it warm up to operating temp. Then put in gear and slowly bring the boost up to 3-4 psi against the converter and then slam the throttle wide open. This will seat the rings and you are ready to run it like you stole it. I've never had a problem doing this in over 30 years of building engines. An engine dyno would be the best way to break it in, but most folks just don't have one in their garage. If the engine has been machined and assembled correctly, no parts should ever touch a bearing. There is an oil film between all parts.

Used this to break in all of my motorcycle race motors. Most reved to 13,000 rpm and I beat them like a drum. Never had a problem.
