Just wondering how high you guys rev your motors.

I've taken my 1.6 NA up to 6000 a couple of times but normally shift around 4000.

So, how high have you taken your motor and it still survived?

I take my 1.5 na way over 4000 when I'm wheelin. Hasn't died yet.

I generally shift between 4000 and 4500 but have pushed it to 6000 more than a few times.. Tyring to pass going up the mountain with an NA no less...

I dont have the gov mod (yet :oops: ), so I dont get past 3800-4000 without bogging down. My usuial shift point is 2250 - 2500

And 6000!!!#! WOW! Anything over about 3500 scares me a bit... I have visions of parts coming out of the hood at that rpm!

Not to hyjack, but do these motors make power up that high? (5-6k?)

Pends on the build.. I know my engine is pretty much done a little under 5000.. All I have is a governor mod, and larger exhaust.. With a Giles super pump I'm guessing it is better...

if you modify the governor properly they can rev up to and maybe higher than 6k and deliver all the fuel you need. timing advance mod might be necessary at that point though... because you need enough timing advance to properly burn that extra fuel :wink:

Last year with all the snow and my unlimited slip transmission the 1.7 na got wound up to at least 5500 a few times. Not great since the motor wasn't really warm but ya gonna do? certainly didn't seem to affect it. It really astonished me when i first found this site. I was under the assumption that a diesel just couldn't breathe well enough do wind up like they manage to.

Routinely wind up past 4000, generally consider 5000 to be "enough". :wink:

I run 4000 at 60mph. I was concerned about cruising rpm that high, but it runs good.

Did you guys ever read in the Bently about setting the max rpm? If I recall, they talk about revving the motor to 5500 rpm and adjusting it to there.
I don't have my book right now, somebody else will have to look.

I was kind of curious what RPM people are cruising at not so much the revs. I dont think the revs are that bad on it. But I wonder how high is to high for prolonged driving.

Rabbit on Roids · « **Reply #11 on:** March 08, 2009, 05:10:05 am »

i read in a bently that you adjust a TD motor to 5850 rpms for the max setting. so if thats a stock absolute redline.. then why cant we balance our bottom ends and turn 6500 or more? i really dont know how many revs im turning, but i shift my gears when the motor starts getting quiet if im really trying to get somewhere fast. i dont really have a top speed limiter screw setting on my pump either. its just backed way way out. this probably isnt the best way to get revs out of your diesel motor, but whatever, i did it when i was still way new to diesels. and it still works too good. so im not gonna fix it.

I usually change around 4k, but when needed, I've seen 5k sometimes... the engine didn't complain... yet. :lol:

About cruising.. I had to do 900 km (550 miles) some time ago to pick up a GTI interior (mint condition, pickup only

), and keeping a good pace, the engine did go between 3500-4000 all the time (this worked as an italian tune-up, btw).

The first n/a I owned I got it stuck in the driveway. After trying to be nice getting nowhere and then upset, I held the skinny pedal to the floor for about 4-5 minutes popping the clutch from 1st to reverse. I got it out and that is why I didn't hold it there longer, I wouldn't recommend this practice and I didn't have a tach so I have no clue what the rpms were. I did continue to drive it for another year then sold it with no engine related troubles.

I don't really like the feeling of cruising at high RPMs for extended periods of time. 3000 is the highest that I like my motor turning at on the highway. Lately I do find myself cruising at 3600 though.
