breaking her in!!!

[raverboy]

Ok everybody, I just got my slowboy racing stage 3 port and polished head installed along with crower titanium valve springs and retainers, crower stage 2 turbo cams, unorthodox racing cam gears, huge accel injectors, cometic head gasket, and arp head bolts. HOW DO I BREAK MY CAR IN WITH THE NEW HEAD?? Should I just get it tuned at 10lbs for the 1st 1,000 miles or what??? I donno want to blow or do damage to the head so I need your guys help

NOt much to break in on a head. You are supposed to keep the rpms a little high for the firs few minutes for the cams, but I think thats it. I break my motors in by checking for leaks, overheating and then running the s**T out of it. But thats just me. Good luck.

WTF thats the exact opposite of what I was thinking, hmmm... thanks for the advice though.

ya......... I just recently had my motor rebuilt, and I had the boost at 8-9 psi, and didnt shift past 4k rpms, for the first 500 miles, and at the first 500 miles, I changed the oil, but thats what I do to break my motor in.

the one thing that you should try NOT to do is keep the rpm's steady while driving.(ex: highway cruising). Try to vary the rpm's to make sure that everything seats properly in the head.

thanks fellas , you guys have been a ton of help. I would have thought that cruising would have been good for it but now I see why i should vary the rpms and drive around town for the first 500 miles or so or drive to school on the highway during traffic hours Sucha paradox

I dont agree with this, maybe you shouldnt hold it at 3k or above, but low cruising speeds is fine, I kept mine in low rpms whenever I can, once I hit 5th gear, I would cruise at 2500rpms, no higher.

Hey let me know how that SB Stage 2 head works out for ya. I am thinking about buying

I worked at a Company that would dyno big V8 motors on an engine stand. Im talking like 632, 540's and whatnot. Anyways they would break them in on the dyno by just making a pass all the way up the rpm rand like you would do a chassy dyno. Lets say the motor made 500 hp. They would do another few runs, all the sudden the Rings would seal.....the Motor now makes 530 hp.

Dont be a pansy, put the pedal to the metal.

If you didn't do anything to the block then theres no reason to have a real break in period. I've always been told that on the head, when getting new cams and what not to just hold the rpms around 2500-3000 for a bit, and then your good to go.

Ding ding ding! Thankyou. Breaking in a WHOLE ENGINE is alot different than just the head.

exactly, not to mention that if you're breaking in the motor, beating on it hard is the best course anyway.

This isn't an engine break-in thread. There of enough of those arguments already.

it really does not matter how high he revs it, of course not at wot and i would suggest not above 5k. if you cruise at a steady rpm you should be fine but a constant rpm can wear the new parts a certain way and they may not seat properly. by varying rpms you are loading the engine and making sure that the new parts adjust to the engine properly. this is a fact.

Hhahahaha, being soft on it is inevitably unavoidable becuase, as you are stating, my mechanic will halfto tune the engine and will more then likely rev those grands I still feel like it's a though .
