What's your method of including some Wide-Open-Throttle?

[Mojo88]

Yes, I'm trying to get specific about various methods of including some Wide-Open-Throttle operation. I think we all realize that it's a good thing once in a while. I guess I'm curious how much, how often and best way to accomplish WITHOUT damaging any parts.

Personally, I don't like to just take off from a start and floor the gas pedal, and then run it up to ~60mph. I think that's a lot of stress and strain, especially on the tranny as it shifts gears. My preferred method is use manual gear selection while driving, set in 3rd gear while cruising at ~25mph and then floor it, running up to ~50mph, then let it decelerate to 25mph, and maybe repeat (if traffic allows). I swear the engine feels a tad smoother after these little outbursts.

If I was regularly doing highway driving, this wouldn't be an issue. However, the vast majority of my driving is local, so I worry about things getting gummed up.
Let me hear what you guys are doing.

When I'm screwing around out on country road, I'll accelerate like normal up to third, but instead of maintaining half throttle or whatever and shifting to 4th, I'll slowly increase the throttle until I'm flooring it, doing 85 or so. On a closed track of course.

Local dragstrip which is also a 155 miles away by the local freeway where i usually run at 85/90 mph getting there
Also a member of the local Challenger/Charger club,where i've ran it up to 140 mph lots,just to prove the truck will keep up,with 3.21's it was good to 156mph,with 3.55's it's done at about 149/150mph

Good, old fashioned Italian tune-up. Personally, I use the shift limiter pretty much always. PU never gets out of 3rd around town, about 2100 rpm. Running higher revs consistently, and letting the engine get to 5000 or 5500 rpm in second gear and above, before shifting, means you don't have to floor it, just use normal throttle application and let it rev out a bit. It keeps things running better and actually seems to get better mileage around town.

Nice answer, thanks. I have done similar, with just getting revs up without flooring it. The big question is: does this accomplish the goal of cleaning things out?? Or is WOT actually necessary?

I'm gonna shoot this right at @Wild one , since I know he's probably been around plenty of engines, haha. What say you sir - can we clean out our daily-driver engines by just getting the revs up, as @Dean2 does, or do we need to get some actual WOT to force the gunk out??

There is nothing more fun than tapping the ERS button twice and matting the skinny pedal.

I like long high speed road trips. Two three tanks of fuel. Montana to Minnesota via I 94 across North Dakota. With a couple of WOT freeway merges shifting at 6200 thrown in for good measure.

If it's gonna break, it'll happen out there.

Several interesting concepts. I do 98% local running, and no speed limits over 60 mph. I can only get it up there is I travel and get on IH 35 and head South, where the traffic moves at 85-100 MPH, till U get North of Austin and tends to go to 10 MPH real quick. I do not like slamming the skinny pedal, but working it up there. I can get up to almost 90 MPH on road from Highway to my place, but since it is only 1.3 miles from state road to my house, to time to goof. The idea of getting revs up by limiter is interesting too, tho I admit a bit leery to it.

Keeping the revs up helps with the oiling issues facing the cam and lifters,but it doesn't do anything for keeping the carbon off the piston tops/combustion chambers and to keep the piston ring grooves clean,to do that you need wide open runs that put enough heat in the cylinders to burn the carbon off and blow it out the exhaust valves.You could do the old water spray in the intake manifold or seafoam trick,then take it out and drive it like you're 16 again,if you do that once or twice a year,it'll usually keep the chambers fairly clean

Stock the engines are governed at 5600,they aren't gonna hurt themselves at that rpm. There's guys running stock bottom end 5.7's to 7,000 rpm,and they stay together.My truck was set to shift at 6600,and i can't say as i ever worried about the engine throwing a rod at that rpm. You gotta remember they're a smallblock engine that's not a hell'va lot more cubes then the old 340's were,and they have a relatively short stroke,they'll handle rpm pretty good

And, being forcibly planted into your seat while listening to the Hemi sing is a very special place.

I will bet that you've had more than your fair share of liftoffs that make our stock trucks feel a bit compromised.

I neva have maxed my RAM out to THE Limiter, so I got no idea where it is set, 107, 8, 9??? I can tell U on my Govt Ford F 150 that I drove the heck out of, it was set at 99 MPH, once U hit 99 MPH, it drop down to 90 MPH, so I learned to never go past 97 MPH.
(2014 F 150 with 5.0L). Just for clarification.

Been 135-140 MPH in the old floating Crown Vic, and that was white knuckle driving trying to keep on the road. No fast jerking of the wheel there, lmao.

I had thought of changing out to a Borla kit and/or 5" tips, but than thought: truk is a driveway princess, just not needed, and I do like to hear the radio. Stock running down road is pleasant for sure. Just IMHO.

Hell at 155 you could drive my truck easily with one hand,lol. Had the wifes Challenger to 174mph,before she started to get mad. Note to self,leave the boss at home if you're gonna take her car out and beat her top speed numbers,she'd had it to 168,and i couldn't let her have the top numbers,

U try and drive a Crown Vic 155 MPH, with unknown amount of MX, proper MX that is, and tires and brakes and and, and the roads like they R, quick trip to the 6 foot under club. Especially on rural roads, state highway, nothing like an interstate.

Always wait to drive spiritedly until the engine and transmission are at full operating temps.

My rig is a DD and already has 57,000Km's on it, and it turns 2 at the end of this coming February, so, I drive a lot, both highway and in town.

So my HEMI breathes better I have a custom mandrel bent y-pipe that goes into a Magnaflow cat back (reso delete, too), and out a pair of 5" tips.

Always run premium fuel and oil/filter, and do a 2-bottle SI-1 cleaning at least 3 times a year.
I also have the Caulk-4 transmission bypass valve as well.

Doing all this ensures that my engine and transmission are running in top condition and can handle daily spankings!

Entering highways (of course, when it's safe to do so) I smash the go-pedal and take her to the rev limiter through several gears...I'm usually at just north of 150KM/H by the time I'm ready to merge onto the highway.

When on the highway, (of course, when it's safe to do so) I'll smash the go-pedal periodically and take her to the rev limiter in that gear... then continue my cruise.

In town I enjoy spirited take offs, and with 3.92's it's a lot of fun, both with and without the traction control on.

Keeping her out of granny mode is important as I always like 100% of my truck available at all times.

They recently changed the law in fl. Where if caught going 100 mph or above, it is now an arrest able offense.
I heard 105 was the top speed limit for my 14 , so now that jail was an option , I tested .
Topped out at 106 .
Highest till then was a little over 95 on the turnpike or interstate.
Pretty disappointed, as my 73 b200 with a 383 hp ,and 323 rear gears , would peg the speedo holding over 120.
For a big brick it hauled a$$ pretty good.

LOL, just have to press your luck to make a point, eh? LOL

Now that Rick said the rev limiter is set at 5600 rpm, I need a warm day to disprove that spec.
I'm sure I saw 6000 rpm last year, but maybe not.

Now, I need to know. Thanks, Rick.

It's between 5600rpm & 6000rpm.. I swear I see closer to 6000 on my tach...
I peg the go-stick to the floor on the highway onramps and don't let up one bit until I'm at about 150KM/H on the highway..
Shifts clean and hard within that RPM range.
