WoodsWagon Posted September 3, 2007 Share Posted September 3, 2007 SPFI EA82 8,000 rpm's. You could hear the valves starting to float. Did it a few times. Still runs fine. Link to comment Share on other sites More sharing options...
Nate007 Posted September 3, 2007 Share Posted September 3, 2007 revved my EG33 to 7k no problem. I've also had a chevy small block to 9K. Link to comment Share on other sites More sharing options...
Subaru_dude Posted September 3, 2007 Share Posted September 3, 2007 pegged the tac when the throttle cable got stuck on the linkage while I was standing outside of it revving. blew a coolant line to the carb. the line needed replaced anyway.

GeneralDisorder Posted September 3, 2007 Share Posted September 3, 2007 I've had all incarnations of EA81's and EA82's to valve float. Never damaged one from it. I had a rod through the block of an EA81 once but it wasn't RPM related. None of them can make it to rod burst speeds in stock form. A member here that was into engineering once postulated that the rod burst speed is somewhere north of 11,000 GD Link to comment Share on other sites More sharing options...
jeffast Posted September 4, 2007 Share Posted September 4, 2007 well, i was driving while talking on my cell phone and took my car to 7200 rpm in second, then asked the passenger to get third gear while i pushed in the clutch, he shifted it into first and i dumped the clutch, and i threw a rod, like a week later, not sure if it was related or not. this was in an 89 xt6 er27 motor Link to comment Share on other sites More sharing options...
TheLoyale Posted September 4, 2007 Share Posted September 4, 2007 SPFI EA82 about 3500rpm in park.. And 4000-4500 in 2nd if i'm on the highway and on a dead stop. Link to comment Share on other sites More sharing options...
Phizinza Posted September 4, 2007 Share Posted September 4, 2007 When I first got my Brumby with the EA81 dual carb motor I tested it on a dirt road in 4WD low. Before I knew it it was about 8,200RPM and still going up freely. Now the engine has trouble going above 6500rpm while driving. That will change though when I build it up. It's just sitting in the shed now gathering dust. EJ22 cuts out at somthign like 7,200rpm? So thats the maximum from that. Link to comment Share on other sites More sharing options...
mikeshoup Posted September 4, 2007 Share Posted September 4, 2007 6500RPM on the EA81T... it just stops making power after about 5500rpm, so there's no reason to pull past that. Link to comment Share on other sites More sharing options...
Corolla Frenzy Posted September 4, 2007 Share Posted September 4, 2007 3000 rpm to drive it from the school parking lot across the street to the driveway. Despite the warped/cracked head, it felt worse than a geo metro for power hahahha Link to comment Share on other sites More sharing options...
TheLoyale Posted September 4, 2007 Share Posted September 4, 2007 When does the EA82 SPFI stop makeing power? 5200rpm? Link to comment Share on other sites More sharing options...
RenaissanceMan Posted September 4, 2007 Share Posted September 4, 2007 I have the same problem with my ea81T. Right when you hit 6K the thing runs out of fuel. I would do 8300 on my EF12 FI on a regular basis. That was the only way you could keep up with traffic anyway. -Mike Link to comment Share on other sites More sharing options...
i_c_the_light Posted September 4, 2007 Share Posted September 4, 2007 EA82T saw at least 9k 4 times for quite a long period. It was totally sharted afterwards. Link to comment Share on other sites More sharing options...
mikeshoup Posted September 4, 2007 Share Posted September 4, 2007 My EA82 SPFI made power up to about 6500. They were pretty high reving motors. Link to comment Share on other sites More sharing options...
TheLoyale Posted September 4, 2007 Share Posted September 4, 2007 Oh really! wow i dident think it would make pwoer that far up! Nothing like a EA82:headbang: Link to comment Share on other sites More sharing options...
Corolla Frenzy Posted September 4, 2007 Share Posted September 4, 2007 So I assume the EA82t has no rev cut? Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 4, 2007 Share Posted September 4, 2007 So I assume the EA82t has no rev cut? Nope - just valve float, fuel pressure, and injector sizing. It's got a fuel cut for overboost, but that can be overcome if a variety of ways. GD Link to comment Share on other sites More sharing options...
kiwi subbie Posted September 4, 2007 Share Posted September 4, 2007 ea71 1982 wagon i red lined another 500rpm it it would go off the clock er27 red lined all most went of the clock due 2 the auto was shot and wouldnt chance up eg33 about 7000 Link to comment Share on other sites More sharing options...

Gloyale Posted September 4, 2007 Share Posted September 4, 2007 So I assume the EA82t has no rev cut? No, but If you've got a MT with Digidash, the digidash will beep an alarm at you when you hit 6000 rpms as a warning. Link to comment Share on other sites More sharing options...
TheLoyale Posted September 4, 2007 Share Posted September 4, 2007 Humm, That's cool! I don't want to rev it to high right now as of i got old T-belts and a leaky MM-seal. I start to get a lifter tick if i diside to put it about 4500rmp in 2nd. So i let off the gas and let it shift. I don't want to hurt my Roo. PS: It's an auto trans.

testy Posted September 5, 2007 Share Posted September 5, 2007 8000rpm on regular basis. Freereving. 93 EA82. 5spd. 7700rpm in 3rd gear. Link to comment Share on other sites More sharing options...
TheLoyale Posted September 5, 2007 Share Posted September 5, 2007 Man, I know Subaru engines are made for high rev's but why would you want to go that high?? I mean 8000rpm just free reving! And 7700 in 3rd! damm that's pushing it a little hard don't you think..... All i can say is i guess there's no carbon buildup in your engine Hahahahahahaha:lol: Link to comment Share on other sites More sharing options...
4x4_Welder Posted September 5, 2007 Share Posted September 5, 2007 Hit over 7k in traffic, in 4low in wonderful Auburn trying to get from I5 north to the left hand lane of 18 west to make a left turn. Scared some people, and the car burned oil worse after that for a couple miles. My old Hatch, in RWD. I did blow a 390 when the motor mount broke, pinning the throttle wide open until it dropped a valve at about 6500rpm. Cracked the block, bent the rod, shattered the piston, and hydrolocked a cylinder on the other side bending that rod. Didn't trust the crank, so couldn't even save that. Somewhere I have pictures where you can see light through the crack in the block. Link to comment Share on other sites More sharing options...
