avatar382 Posted March 19, 2005 Share Posted March 19, 2005 No seriously, does it? It's so much more fun to drive an ea82 keeping it above 3-4k rpm. Where do the valves start floating? I saw 7K rpm this morning, and they seemed fine! Quote Link to comment Share on other sites More sharing options...
Lukas Posted March 19, 2005 Share Posted March 19, 2005 I never rev my EA82 over 4000RPM, I shift at 3000RPM most of the time. Lukas Quote Link to comment Share on other sites More sharing options...
Vanislru Posted March 19, 2005 Share Posted March 19, 2005 Valve float depends on the cond. of your valve springs, if they're new or have never really been abused then it'll happen at the upper rev range. I have 2 86 ea82t's and the lifted wagon floats em at 7000rpm but the rally wagon floats at 6500rpm on a good day. If you install some new springs or stiffer aftermarkets then you should be able to take it up to 8000rpm with no float. Quote Link to comment Share on other sites More sharing options...
Syonyk Posted March 19, 2005 Share Posted March 19, 2005 How can you tell that your valves are floating? I usually shift somewhere between 5k & 6k when merging onto the highway. I learned that if I treat it like a rotary engine, it's much happier. -=Russ=- Quote Link to comment Share on other sites More sharing options...
bushbasher Posted March 19, 2005 Share Posted March 19, 2005 when the valves float you will hit a flat spot that you cant rev past, and you will hear it too. my spfi wagon floats at a bit over 7500 according to the stock tach, and its got 290k kms on it. My old turbo wagon floated somewhere above 7k according to the digidash. Quote Link to comment Share on other sites More sharing options...

I saw 7K rpm this morning, and they seemed fine! it seems to me that in that range(3-4k rpm) is where u get most of the engines power.

TheSubaruJunkie Posted March 20, 2005 Share Posted March 20, 2005 when the valves float you will hit a flat spot that you cant rev past, I guess my valve float is around 4700-5000rpm -Brian Quote Link to comment Share on other sites More sharing options...
RenaissanceMan Posted March 20, 2005 Share Posted March 20, 2005 with an open exhaust (sidepipe) and a carby cam on a spfi engine I was able to get mine to rev to 8 grand without complaining (No low end tho, so I switched it back) Quote Link to comment Share on other sites More sharing options...
rallyruss Posted March 20, 2005 Share Posted March 20, 2005 I guess my valve float is around 4700-5000rpm -Brian thats restriction you feel or somthing else wrong. it wont float that early. trust me I raced that car. I never take my cars over red line but right up to it on occasion seems ok to me. subie94 and lukas must drive non turbo cars. turbos like to run at high RPM. just the nature of the beasts.

bushbasher Posted March 20, 2005 Share Posted March 20, 2005 I guess my valve float is around 4700-5000rpm -Brian The rpm that your valves float will be the same under accel or free revving. If your car cant make it to the rpm under accel that it can while in neutral, then something else is restricting/your powerband drops off really quickly.

erik litchy Posted March 20, 2005 Share Posted March 20, 2005 once in a while ill drive it at 5000 rpm for a few miles to clean things out. Quote Link to comment Share on other sites More sharing options...
Vanislru Posted March 20, 2005 Share Posted March 20, 2005 I redline mine everyday and have for a year and half. It likes it that way:lol: Quote Link to comment Share on other sites More sharing options...
subiemech85 Posted March 20, 2005 Share Posted March 20, 2005 beyond redline!!!!!!!!!!! 6.5K is where the ea81 sounds the best with ea82 carb, intake maniflod, and complete exhaust with glasspack at the end I held it there for a while of course, I let it warm up to normal operating temp first, I ain't stupid a redline a day keeps the gremlins at bay anyone else redline the ea82 in 1st rwd lo goin up a muddy "road"??

dragonwingsubaru Posted March 20, 2005 Share Posted March 20, 2005 hey subiemech ive done that 1 quite a few times while offroading i believe most engines need a redline every now and then if nothing else to clear the crap outta it lol Quote Link to comment Share on other sites More sharing options...
iluvdrt Posted March 20, 2005 Share Posted March 20, 2005 My ea82t makes power all the way up to 7k. I have never taken it farther than that though. It pulls hard throughout the entire rpm band. Quote Link to comment Share on other sites More sharing options...
bushbasher Posted March 21, 2005 Share Posted March 21, 2005 anyone else redline the ea82 in 1st rwd lo goin up a muddy "road"?? Just about every time I get in the thing In double low thats about jogging speed Quote Link to comment Share on other sites More sharing options...

soobscript Posted March 23, 2005 Share Posted March 23, 2005 I do up to 3 hrs. a day highway in my RX. 75 mph = 4000 rpm. Usually shift around 3k, but it's seen 6k a few times since I got it. (BTW, 195k engine with gasket problems) Quote Link to comment Share on other sites More sharing options...
