No Red line on tach


most people stress about rpm way too much...

Spoken like a true 4 banger guy:ROFLMAO:

Go run a 460 to 5000+ RPM and tell me your thoughts.

I get nervous when it kicks out of O/D on the freeway at 70mph.
 
cars didn't have red lines on the tachs back in the day. shoot, they didn;t even have tachs.

i cannot remember which car i had first with a tach but i know it wasn't the karmann ghia, beetle, or 65 mustang.

My favorite is when manufacturers install a tachometer in a vehicle equipped with an automatic. You have to try in order to red line one of those. Like put in 1, 2, or N. In drive, you'll run out of power in most vehicles before you hit the redline.

Why you gotta pick on my Corolla like that? LOL
I was just going to mention my 1.8L Corolla has an auto w/tach. It also has a form of variable valve timing that has a 2nd powerband similar to the Honda V-tec, but not nearly as fun. Redline is a 6,500 rpm and I've never even come close to that. Myabe 4,500-5,000 rpm once, . . . maybe.

Ok, true, I do contemplate things much differently when I'm driving my F350, it just seems wrong to rev that 7.3L all the way up to 3200rpm :). On the other hand when I need it it doesn't phase me to go up to the 5k rev limit on the 5L explorer...
 
I liked the 3.0 in Tauruses after the first 2 years. The 86's were prone to piston slap, especially when driven a bunch of low speed short trips, which was fixed with hypereutectic pistons. The 87's didn't knock but the off shore head bolts often broke. It worked poorly in Windstars in the New England hilss s owe didn't sell many. I thought they were just OK in 2wd Rangers with automatic transmissions and absolutely useless in 4x4's.
I never liked the 4.0 sohc so I drove a new regular cab 4x4 Ranger with a 3.0, 4.10's, and a 5 speed during lunch one day. I had to downshift to 4th on the highway at 60 mph to maintain speed. I ordered the 4.0 in mine. The torque peak in a truck needs to be a lot less than 3000 rpms to be usefull in hilly country.
 
I liked the 3.0 that SHOed up in '89. it was fun to bounce off the 7400 rpm redline. :icon_thumby:
 
i like the 3.0 in my ranger. its great. 90mph all the way to colorado from the bottom of texas and no trouble going over raton pass in new mexico
 
Wow, I got a lot of input on this one. It's a remanufactured motor so I'm not going to take up to any of the maximum RPM. It is nice to know the highest RPM that is recommended, I have a couple of motorcycles and one of them I use to run it up to maximum RPM regularly. I'm older now but I'm going to get the older one out and work on the engine so I can ride it again. If anyone is wondering, the older one is a 77 KZ1000 and the newer one is a 1990 Goldwing. I got the Goldwing so the wife would be more comfortable about 10 years ago and parked the KZ.

Everybody and their brother wants that kz motor... extremely good base for a drag bike. My boss has one bored&stroked to 1400cc or so and it'll trap 5.6 in the 8th mile.

I get nervous even in my jeep. Its kicked into 4th before towing up a hill at speed. Cranked like 4500rpm...i laid off lol.

Redline is 6500.

I dont have a tach in my ranger but i doubt ive had that over 4500
 
My 02 4.0 SOHC rev limiter is set at around 6200 rpm. I don't hesitate to run it up until just before the injectors shut down at the rpm limiter. I don't hold it there I just grab another gear until I reach the speed I want. I don't treat it any differently with over 292K miles on it. I don't do it all the time and do it less as I get older (grow up) and wiser.

"Best Torque decides when you shift if you want the fastest acceleration, so go 200rpm above best torque then shift to next gear, that should get next gear 200-300 below best torque RPM, so still in the power band of that engine."
That sounds good in theory but if you used that approach in a race, you would most likely watch taillights zoom ahead running against a similar vehicle with a knowledgeable driver. Even if you go well past the peak torque in a lower gear, you will still have more torque to the wheels compared to shifting into the next higher gear. Lower gears are torque multipliers. Higher rpm will typically go on to higher HP too. Even if you go past peak HP, you will still accelerate faster in a lower gear. That is until the engine HP or torque drops off too much.

My 2000 Ranger with the 3.0 and manual, I used to turn onto highway on-ramps in second, rail on it until I was into peak torque for 3rd, grab that and run it all the way up to 65-70 mph and pop over to overdrive as I merged. Unfortunately I also did that in front of a cop (unknowingly), he was not as amused as I was and made sure I knew it by the end of it. Still didn’t stop me from doing it, lol.

We've got a 460 (well, 497, I think) that regularly sees 8,000 rpm. Of course about the only original Ford part is the block itself. It can be done. LOL
 
You could get to know the motor by feel instead of by sound.
As it gets to it's feet in one gear move it on into the next, you shouldn't have much trouble doing that.
You really should feel it somewhere, such as the steering wheel, gas pedal or the shift knob, even somewhat as it pulls you back in the seat
I think if you give something like that a shot you'll be just as well off, possibly better
