For an engine?

 

Or to even go over 80 for a few minutes...

 

if you were in 2nd gear in a 5/6speed yes it would be bad. But if your crusing..i usually cruise at 90ish.

 

So it doesn't run the engine really hard cruisin?

 

Just watch the RPMs. Make sure you're not in like 2nd gear pulling 4500 rpms. On the highway, its usually between 2000-3000rpm, depending on how fast you're going (Speaking in terms of auto transmission).

 

no

you might be thinking about break-in... that's when they recommend you vary your rpm/speed (and even that's debatable).

Once you get past 1,000 miles, you can drive at 90 in 6th (or 5th but it would waste gas) all day. 90 in 6th is less than 3k rpm. You'd do damage if you went 40 in 1st, but 90 in 6th won't hurt anything.

 

mine goes 80 MPH for about an hour eevry day.

 

 

Can you imagain the car problems the Germans would have, being that they cruise at speeds over 100MPH on their highways.

 

manual 3.0 5th gen is at 3200 rpm at 80mph, and at 4000 rpm at about 90mph. Guess what I just made a 1200 mile trip last weekend and my RPMs barely dropped below 4000RPms...gas mileage sucked at 20MPG though

 

Yep, made a one day business trip from Houston to Austin and back again...around 266 miles total at 80+ mph. Engine was fine, economy wasn't.

 

you need a 6th gear D: .... 3k rpm in 6th is 93 mph!

 

in order to sustain speeds of 90+ in FL, NV, TX and so forth, you're going to need a tranny cooler. You might go into safe mode and have to pull over let it cool (and restarting car to get out of safe mode).

I've gone 100ish in cool weather for over an hour. Obviously I was in a place where that is acceptable and speed limits arent enforced.

 

This I just dont believe....cant do it...wont belive it

 

How much are tranny coolers, and where can we get them? (and what are the better brands?)

 

I go about 85 all the time too, thats why I asked. I just wanted to make sure it wouldn't run the engine down.

 

5am, about the 15th hour of a 17 hour trip. My max sustained 75+ for 17 hours, lemans style - only stopping for max & driver fuel. Didnt say 100ish for an hour wasnt nerve racking.. I knew I *could* be stopped. But I also felt better in the fact I was being passed frequently!

 

i told you if you go more than 90 you'd need a trany cooler.

 

Where was that pic taken at?

 

B&M tranny coolers are good. You can get a Hayden from Pep Boys for pretty cheap, about $45. They need a little more time for warming up than the B&M because of the design. So if you are in colder weather, I'd go with the B&M.

I've done over a 100 for 3.5 hours from Las Vegas to Los Angeles a few times. My 2k auto still runs strong,

 

haha ya you did, but that is for a long period of time right? How much is a cooler?

 

if your going to tampa from here you should be just fine without one. work on some actual performance mods first so you can keep up with the 3.5's.

 

haha I got it, believe me I got the 3.5 in my sights.

 

That's funny, I recently did the exact same trip. On the way up, 90+ most of the way (I was running late) - no problems, bad gas mileage. On the way back, about 85 the entire way, and about 24 mpg (which is GREAT for me, since I usually drive in the city and see something like 16.

Regarding running at steady 80+ for extended periods - as said above, no problem. Engine rpm is low, and you're not heating up the wheel bearings etc. excessively.

 

Is that for any car or just the Maxima?

 

any car.

So now we'll ask, why do you ask? You seem awfully interested in this, like you plan to drive over 90mph for hours on end....

In normal operation you do not need a tranny cooler. It won't hurt, but 90% of the time it won't "help" either (meaning you're not going to 'gain' anything if you install it). Do you think you drive like the other 10%? Are you a road-warrior salesman (I have a friend who drove 75,000 miles last year)? What's your story?

Like slickrick said, put the money toward some real performance mods instead.

Oh, and they range in price from around $275 - $1,000 depending on what you want.

 

I drive up to Los Angeles about twice a month and frequently drive 80-90mph for a good hour or so. I already have almost 1000 miles on my car and I just bought it 3 weeks ago!!!

 

I bought mine last July and I have close to 13K.
Thank God for Real Estate and Tax Write-Offs!

 

Not at all,
A Ford Aspire maybe (if that)
But no Max.

I used to drive my Q's much faster, once for 95 mph for a full half tankful (desert west).

Fred..

 

Bro, when i roll on the florida turnpike between MIA and ORL i go 100-110 all the way. 18000 miles and not a problem.

 

FHP is usually easy to avoid on 75, so I can see how that is possible.

 

Well my car used to drive on the interstate at high speeds for an hour a day for a few months, so I didn't know how bad that was for the engine.

 

Mine goes 80mph a day as well, but no longet then a total of 2min. I do alot of steet driving 90% steet 10% freeway/highway.

 

sneaky lil bastard

 

Hey I try, I dont do that unless I just break free from a rollin roadblock.(Slow cars in all lanes goin speedlimit of below=roadblock)

 

then that pic should look very familiar

 

I usually always get around 20-21 mpg even when I drive normally. That's not good. What's the best mpg you've gotten?

 

Turnpike not I-75. FHP helicopters and cessnas have I75 on lockdown

 

That's what I meant, turnpike, but I drive 75 all the time, and I've never seen a helicopter or cessna busting speeders.

 

I did my run at night on the turnpike.. It was all fun except when the deer started peeking out.. I about soiled myself, its what finally slowed me down.. Nobody else seemed to care
