explan to me what about a turbo needs to be broken in?

there are different preferences to how engines should be broken in. some say take it easy for 1000miles. others say beat onit right away to get the rings to seal properly. seems like the beating on it theory has be proven to me quite often in the past few months

you home yet fiz?

i bet he slept outside the shop overnight...

by the way anthony as you can see from my sig i heart that picture you posted

I am going to chime in here:

Great job Fizzy. I have been on these boards since you first got your 240 and swapped the rusted hatch. Remember that write up?

Another thing: I would say take it semi-easy and let the engine see 1-3 pounds of boost for about 250 miles. Then 3-6 pounds of boost for another 250. Change the oil to synthetic at this time and go dyno and beat the living hell out of it. That's my own sort of formula. I don't agree with beating on it immediately (for longevity's sake). But 250-500 mile break in isn't that bad. Someone told me 2000 miles once. I just don't think everything will seal up well enough if you don't ram on it for that long.

A few pulls on the dyno for tuning purposes will not hurt the motor as long as he has oil circulation. If he runs into a lube problem then he may have issues. The brake in period is usally 500-1000 for me. That doesn't mean I won't occasionly flog it though. Daily driving with a few high boost balsts has never doe me wrong. I used this method on 5 or 6 RB20's and a couple RB26's.

I also don't use synthetic till 1000miles goes past. I brake it in with the cheap stuff.

Yeah for Fiz!Damn good numbers for a crappy tune.

Still waiting to see what the EMS will do...

Nice numbers fiz even with a ****ty tune and no methanol yet and BTW I'm stealing that pic with the methanol for my background that's F***in sweet.

you know i don't know for sure what it is exactly that needs to be done with breaking in a turbo, i have just always heard/read that it is good practice to go 500-1000 miles without boosting it up...

it made sense to me because when i first got mine installed it didn't spin very freely (floating bearing) and then after daily driving for a few weeks and taking it easy on the engine it spun/still spins soo easily and just wants to boost up all the time... and no my foot has not gotten more heavy.

i guess i shoudl have a more definitive answer here but it just made sense to me that letting it get used to spinning all the time and warming up/cooling down etc was something that a turbo should be introduced to slowly. i didn't really question it, because those reccommendations came from turbo manufacturers (not just mine but multiple kits for different cars and multiple websites etc.). i guess i should have asked why maybe but i just accepted it as it was no inconvenience anyway because i couldn't boost my car up safely at first because i hadn't installed the fuel pump yet...

anyhow so if anyone has a definitive answer to why does a turbo need to be babied for 500+ miles please do tell...

my reasoning was kinda along these lines i guess:it just made sense to me that it would wear itself into spinning the way it should because all of the seals/gaskets/everything are new... so i just thought that babying it for a while would maybe promote the turbo keeping good seals and everything while it gets hot and gets cold (expands and contracts)... i don't know i could be way off here... someone else want to chime in?

sorry not trying to thread jack here...

[HolyShiznit]

I wasn't talking about breaking a turbo, I was referring to breaking in a motor. Sorry.

[hysteria]

nothing to be sorry about, if you look i was responding to structure. no worries mate.

i guess this thread is done since he just boosted 20psi..........so much for the "proper break in period" lol. congrats again fiz
