on monday i get my car back from the shop, it will have a drag gen 3 kit, jg intake manifold, 3" turbo back exhaust, act aluminum flywheel and extreme clutch. then after i break it in (i was thinking about in a week after i put about 200-300 miles on it) having it dyno-tuned with hondata, rc 450's, and running 10lbs. anyone have any other suggestions, or does that sound cool?

on a new clutch i believe it is a minimum of 500 miles to break it in properly...I would think more that way it gets broke in properly and doesn't have any trouble down the line.

the act recommends 200-300 miles on their street disk. I just instaled mine last week.

I babied my car for the first 300-400 miles, then I drove it hard (but not reving past 6000 for the next 200 miles...then I changed the oil and drove it like normal

alot of clutches need 400-500 miles to be broken in correctly, but some may only need the 200-300 miles as mentioned. i personally always go by the instructions, sometimes even going a bit over the needed breakin mileage to be sure it's ready for the abuse it's gonna see. once the clutch is broken in then i'm sure you can start boosting (or start hitting full boost) and use the higher rpm power.

when i comes to an engine breakin (i think you only were referring to a motor that now sees boost for the first time, not actually rebuilt competely with internals) it's a bit more detailed than a clutch breakin so that everything seats properly and the rings seal. to put it simply, you can raise the top rpm limit 1K every 100 miles that are put on the engine. for instance drive 100 miles shifting at 3K rpm, then 100 miles up to 4K and so on. some do a "race breakin" which is normally almost an instant breakin, but that depends on the how the car will be used and the time schedule etc. i use my motors for daily driving so far, so i take my time breaking the motor and clutches in.

ahh excellent, all very good info. yeah im going to have a brand new clutch, and a motor taking on boost for the very first time. so im going to be putting mad miles on my car this week. the taking it up another 1k rpm every 100 miles sounds good. im also going to have a daily driver and i usually shift between 3-4 on a regular basis. thanks for the info

sure no problem. also what was mentioned before about oil changes is good info.
when breaking in a rebuilt motor it's good to change the oil and filter after you run it the first 20-30 minutes (at 2-3K rpm to help seat the rings and bearings etc at first startup) and also after the first 500 and 1000 miles as well. just to be safe and keep everything clean. you should be able to feel where the power falls off on a rebuilt motor that is being broken in, when you feel it fall off then you know to shift. then you can keep shifting at that point for 50-100 miles, whatever seems good for the motor, til you get to redline.
