I am running a quadzilla box and I run it on the 215 Level and it raises the rev limiter and yesterday I was rappin it out pretty good and let it go to about 4500 in first second and third and I know it can't be good for my engine but wondering how bad I'm hurting it by doing this. Let me know what yall think.

I know that range is ok when using the engine brake while towing. But remember its a diesel not a gas engine. :bigglasse

 

[djms]

ANyone have any more info on how bad this is?

 

[moss022]

i use to run that box, my motor is still going so far

i use to run that box, my motor is still going so far

Key words there I USE TO RUN THAT BOX... lil high for the :chevy: eh?????

 

[moss022]

red line in the tts box=4500. the only time it sees that high is in a very loose track, or a very very bad shift, and even an input shaft breaking too

 

[MartyK]

high rev's mean heat. lots of it. Diesels dont like heat, hope youve got a good exaust.

 

[djms]

well it make me feel better hearing that you have run that kind of rpms and that your truck is still running.

 

[moss022]

imo high rev's means less heat.....moving more air. and diesels do like heat

 

[nay6]

More RPM's = more friction. Friction = heat. Therefore RPM's = Heat. Just a little algebra for ya.

4500 probably wont hurt the motor, the turbo is another story. i blew mine doing a burnout....i dont think my truck will rev to 4500 unless its spinning. going through the gears it will shift at 3700 or so

 

[McRat]

Yeah, it will probably smoke a stock charger. You won't make power up there without nitrous.

 

[moss022]

the friction creating heat is probably nothing compared to the combustion going on. my bet thats where the heat is coming from. god help the gassers that run 8k+!

 

[ecc_33]

ive hit 4500rpm's in a few dmaxes and there still living....my guess is you will be alright just dont make it a every day thing

 

[JOHNBOY]

Cant even count how many times I have been to 4500 and past. Still running strong.

 

[moss022]

must be those good exhausts!):h

 

[djms]

This happened while spinning the tires, gonna have to get out if it a little sonner I guess. Will try not to make a habit of it

 

[New_LB7_Owner]

More RPM's More Btu / Horsepower = Heat Diesels like heat in the right places just like padding on some ladys. Just don't abuse it..... control the extra

cyl. wall to piston friction makes up the majority of friction in an engine (roughly 65% I believe)...and it goes up exponentially with rpms, that's why high rpm motors usually only run 2 rings. that combined with the heat from diesels combustion properties = lots of heat....all that said, it's only 4500rpm, I wouldn't worry about the rotating assembly
