Figured id get the most looks here.

Just wondering how the 3.4L likes being rev'd up high. I hit rev limiter in it a bit, but im driving it hard, Ive hit it many times wheeling, but i don't let it just sit there and bounce off it for a long time. Is hitting the rev limiter and holding it there for a few moments okay or is that too hard for it?

I know a bunch of people who are under the impression that the 22res can bounce of their rev limiters all day and be fine as long as it doesn't overheat.

A few of us were just wondering the info about the 3.4Ls and how it tolerates such driving.


Discuss. Thanks.

crap i know i spelt the title wrong but i can't sleep and im tired as hell.. lol

 

I wouldn't do it on a regular basis but with the 3.4 being a bit overbuilt form the factory you're probably ok.

 

i got a completely stock 3.4 its got 218,000 miles on it and ive never replaced the timin belt head gasket nothin the motor is completely stock excpet the alternator that is new ince i burned it up muddin. but i constaly rev mine up to 5.5 to 6,000 rpms and i have never had a problem wit my motor im the only guy in my area with a stock 4runner that will race ricers with turbos and beat the snot out of them all day long and i een have a fully cutom front bumper made out of 3/8 steel plate it weighs at least 150-200 lbs and im still beat the snot out of it without a problem.

 

bouncing off the rev limiter is the best though.....

 

does that thing have vtech?

 

Heck yea man..

Along with my super light, titanium, ported and poslished, aeronautical, nasa approved, custom, hybrid, antimicrobial, anti bacterial, shiny, superchager!!!!!!

 

but you dont have 3 angle valve grind like i do. Adds 20 hp. Also, are you running dyno hybrid full synthetic. If you are, you can run 8k rpm all day. Just so you know.



okay all kidding aside, as long as you're not reving to 5k in neutral should be okay and as long as you're not pinning the needle for more than you need to should be safe.

 

Define 'revs'? I can put mine on the limiter all day, as the blower loves pushing it there & honestly, it just sounds great.

BUT- you're asking for trouble due to two main factors:

1. The factor rod hardware doesn't like revs, nor do the rods for that matter.
2. The valvesprings are pretty much done at 5500rpm anyway, and frequently hitting that # greatly shortens their life.

If you want to spin it a bunch, build some heads & get some good rods. Then never look back.
