Break In time after new turbos?

kennejp · 07-17-2010, 04:08 PM

Hey guys just had my turbos replaced under warranty. I was trying to figure out if there was some kind of break in period for the turbos before I put my tune back one? I have driven it about 100 miles now.

when i put bigger turbos on i drove "normally" for about 50 miles than gave it a go on 15 psi straight away and kept on pushing. Just make sure the engine is warm and oil on norm temp.

No break in needed as there should always be a film of oil between the common shaft and bearing journals. Slap on and go!

Are the new turbos a big difference? How much whp are you putting down?

Most shops will recommend you prime the engine before starting to make sure the turbos are properly lubricated but there is no break in period for turbos.

big turbos = very big difference. at 19 psi i guess i was putting down around 420 whp, 60 whp over stage 3 than at over 21 psi i blew my engine.... look up my thread for more info.

guaranteed the tech floored your car when testing after the install. no need to worry

probably doesn't matter but I drove "normally" for about 50-75miles before going crazy with mine. you should be fine either way though
