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?
SO, finally made new pulley for my m62. Its between 55-60mm. Its stock g60 alternator pulley with little modifications. Now need bigger injectors. I think 440cc is enough.
Hope to boost 1.5 bar and hope that engine will not explode Management is megasquirt with mtx-l WB. Can anybody have some clue how much power would it make? All other engine bits are stock.
