on my 86' n/t 13b f/i 5spd with 79,xxx miles..

I am curious I heard these cars run better if revved high and hard alot.. and dont endure prolong periods of sitting time..

my question is how high should I be roaring the engine up to before shifting normally?

how high on occasion?

and if I am crusiing it is better to be in a lower gear at 3k-4k or in a higher gear at 2000-3000 rpm?

Might search, as this has been covered a LOT.....but a redlining isn't bad.

 

redline a day keeps the carbon buildup away
also so that the secondary ports open and have the secondary injectors kick in.

 

Depends how much gas you are willing to use. You use more when you shift past 3800 as thats when the secondary injectors come on. I usually shift at 3000-3500 for normal driving.

You should redline the car every once in a while. Most people do it every day. I do in both of my cars.

 

Everyday, just past the buzzer. And also a rev down when turning it off. Sweet sweet smell of rotary engine.

Worst carbin'd engines I have ever seen where from people driving like a panzy.

 

EveryDAY!!!!

 

Or from automatic cars, since they won't redline under load. I've seen some carbon'd up rotors come out of an automatic car.

 

I usually shift between 3-4k, redline a couple times a day. Use good oil, premix and follow proper maintenance.

 

dont be afraid to rev every so often but in normal conditions keep it in the 3000-3500 range. Its good to rev at least a good 6000-6800 sometimes to get the nasty carbon out but remember thats just a quick fix. No matter what you drive, if you are consistently driving the **** uot of your car, its gonna take a crap on you.

 

the"buzzer" when is that lol.. I usualy push to 5-6k when joy riding (atleast a time or two a day)

another question is you said use a good oil and "premix" Are u saying I should premix my oil? and if so with what and how much?

Dave

 

Street_knight just asked about premixing and I responded to it. Check it out, it should be near the top.
I personally drove mine fairly conservatively a lot of the time, but always made sure I had enough room to do a full-throttle acceleration on the highway on-ramp. I ran mine to the rev-limmiter, but my car actually made power that high. Most cars die off before the reline so theres no point.
Also, the buzzer is a bit before redline.

 

I replied to it!

 

nice

 

.... I premix and my car feels smooth all the way up to (and sometimes past) redline... I remember my old base model... I redlined the **** out of that car almost everyday.... on the original motor... It lasted me through high school... It finally blew after me abusing it for about 3.5 years (didnt know any better, or at least I didnt want to) w/ 220K on the clock... Anyway, now sometimes when I drive my cars now, since my 7 has a lightweight flywheel it gets to redline pretty fast now... Its a good thing I have a shift light... Also, I noticed that since I started using the light weight flys, I tend to drive more in the higher rpms normally.... I think if you do all of your normal maintenance on the car and keep it healthy, then it shouldnt be much of an issue...

 

so I shoudl give it a good rev or two a day, I should use some premix in with my regular gas every fill up, and I should enjoy my 7

Well, before I bought it my car was raced on a track a whole lot and it lasted 215k. Plus it died of coolant seal failure, not engine wear.

 

saweet

 

Me too. My car died of a coolant seal failure... The funny thing is that it was my fault and I didnt know it. My Alt/fan belt kept popping at the worst times, causing my car to overheat really fast and I didnt know why... It turns out, that because I removed all of the other belts and only left the one main belt I should have used the dual alt pulley to avoid that... Well, I didnt know about it so the belt kept popping and I let my friend drive it.... Well, he didnt pull over when he saw the temps go up because "he didnt want to get stranded on the side of the road" so the car overheated bad and the seals were toast... Even though I was pissed at my friend for not pulling over, I knew that it was my fault too for not fixing the problem to begin with... Thats a stupid way to loose your first car... *shakes head in disgust*

 

uhhh
no you dont.

first, staging is at 3644rpm
second, just because the secondary is firing doesnt mean it will eat more gas abnormamlly - it is a gradual increase of fuel with the rpm - why do you think cars bog when the secondaries fails to fire *gasp* because the injector cycle on the primaries are cut to ****!

 

Injector duty is split between the two sets when the secondaries kick on. So... +2 to slpin's post.

 

saweet.. I want to go drive my 7 now LOL

 

if you shift at the shift light you will get the best mileage, i did that for a tank, and got somthing like 23 mpg. wasnt very fun, and it took a lot of patience while everyone passes you with angry looks and birds, haha

 

yeah no thx I like high end!!

 

is it really necessary to go all the way up to redline to reduce carbon build-up? I would think anything above 3800 would exersize the secondary injectors and reduce carbon build up. I would think redlining puts unneccessary stress on the engine and accomplishes nothing that 5000rpm wouldn't do, other than stretch your smile muscles more.

I usually shift around 2500-3000 normal driving, 5-6k having fun, and around 7k-7500 when pushing it. I have only gone to the buzzer once. I could barely hear it because my exhaust is so loud.

 

Yeah, I could only hear my buzzer when I revved in neutral.
