At moment my eaton m62 blows 0,5 bar at redline. Original m62 pulley is 94mm.
Is this formula correct for calculating eaton rpm?
(Crank pulley / Eaton pulley) * redline
I am not sure,havent measured myself,but found on web,that g60 crank wheel is 140mm.
So with stock pulley i should have
9234 rpms at redline.
And with 60mm pulley i should have about 14 500 rpm at redline. 14500 is also limit of eaton m62. After 14 500rpm its not so effective anymore.
Also did this calc. I have 9234 rpms and 0,5 bar? So does 4167 rpm gives 0,25bar? And 1846 rpm 0,1bar?
If these calculations are correct,then with 14 500 rpm i should have 0,8bar at redline?
Please correct my. My math isnt the strongest and i dont know can i calculate these things so easy?
What pressures you guys have gotten with m62 and smaller pulleys?
Well read old posts,and someone had 16psi on M62 with 54mm pulley.
I started to make new pulley,smaller. I use G60 alternator pulley for this.
Must drill pulley 44mm to 45mm inside,so i can use 30x45x20 needle bearing. Then must drill otherside hole 4mm larger and use some parts from original m62 clutch.
Pictures are coming soon.
Hope to boost 1 bar after this.

so im currently running an autothority stage 3 tune ,with stock injectors(risky iknoe) 3.5bar fpr,260 cam, along with a fmic. i recently lost a good eaton to a machine shop turns out they bent the rotorbearing plate while trying to remove the old berings and it was toast.... today i finished up with mounting the new eaton,along with the intercooler tubing all seems well it starts right up just have to get around to looking for a slim radiator fan i cant wait to test drive it i mean thatm90 whine is music to my ears
so i took my corrado for a test run today from the get go first way very responsive when at wot second is were i get a jerking motion then it cuts out when pushed to wot under load could this be a fuel issue? the eaton is not putting out that much psi so i dont think its a fuel issue but i could be wrong im thinkg about retiming the motor with the eaton on mabey this will help because i was running the g60 charger on a slightly retarted timing ? any help you thread Gurus?
Fueling (or lack thereof)
Timing (can't hurt to double check it)
charge temperature (the eatons are known as a "heaton" for a reason... you'd best have a GOOD IC on there to keep it in check)
This is sounding very similar to what I was experiencing on my 16VM90 setup. anything over 4-5krpm (highway in particular when it had a chance to load up)... car would buck, shudder, fall on its face. I originally attributed it to blowing out spark (running a 25 thou gap)... but not so certain now.
I never did figure out what was going on, as my giggle nerve over-came the intelligence part of my brain one morning... ignored all the bad noises n signs... 3-4-5 pull on the highway... now it runs on 2 cylinders... ... ... Don't drive it hard until you figure out what your problem is... unless you LIKE replacing motors for no good reason?
