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!

I never rev my EA82 over 4000RPM, I shift at 3000RPM most of the time.

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.

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.

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.

it seems to me that in that range(3-4k rpm) is where u get most of the engines power.

I guess my valve float is around 4700-5000rpm

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)

I guess my valve float is around 4700-5000rpm

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.

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.

once in a while ill drive it at 5000 rpm for a few miles to clean things out.

I redline mine everyday and have for a year and half. It likes it that way:lol:

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"??

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

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.

Just about every time I get in the thing In double low thats about jogging speed

I buried the tach in my brat today!!!!!!!!!!!!!!!

 

and the tach stops at 8k

 

it idled to warm up 2.5 hours before I did that

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)
