when to rev

[dodgeGTI]

Hey guys, how many k's should I have done before I can get the engine up to 5800rpm to get max power?

The manual says to stay below 3/4s of max power for the first 1000kms.

Get the manual out of your glovebox and give it a good read when you get home tonight. There is a fair bit in there to learn.

Formula 1 teams and superbikes don't have hours to spend running in their motors.

True, but I doubt any of us have to coin to change over engines as often as F1 and motoGP teams.

If you've babied it, you'll be slower then someone who has gunned it every where. First weekend I had mine I did bout 800km, most of that was between a max of 4Krpm-5Krpm

5800rpm might be redline, but power starts to die between 5000rpm & 5500rpm.

5800 isnt redline, and VW say that peak power of 110kw is at 5800rpm.

oops who put that 5 in place of the 6 Actually redline is prob 7200rpm

I normally change at 5500, there's a real dead spot around 5500rpm.

While the motors are bench run, im not sure how hard they are run in, and I would hazard a guess that its only the engine and not the gearbox/drive train etc

Check this out for a bit more info on how they are starting to run in the motors at the factory...

When I was last at Wolfsburg, they were just switching to the Golf V production (back in 05').

The production line ended at a multi line dynometer where the cars rolled off the production line and sat on top of the rollers. They then proceeded to rev the crap out of every car up & down the gears for about 10 minutes per car. & I mean hitting the rev limiter in each gear.

personally I think that that is worse than giving one to a bunch of journalists!

Anyway - the theory explained was that if anything was wrong, that was the place to find out. Now these cars were dead cold, zero miles straight off the production line. I don't think anything we do could compare to that

I'm sure it would be the same at the other plants!

two of my wifes cousins work for a well known trucking company that collect cars off the wharf.everytime I see them at a family do,I ask them the latest fun they have had.they have THRASHED cars from r32 golfs to jags to renaults to rs4 audis.so if it comes from o/s they have driven it.they explained to me that the cars are first collected off the boats,burn outs all the way out,many scrapped on the way out.then passed onto the truckies.thrashed again all the way onto the trucks.they think its part of their job!!!
so as guy_h has explained ,first thrashed in the factory.collected by truckies,thrashed off the truck,thrashed by the wharfie there.thrashed by a wharfie here,thrashed by a truckie here.thrashed by some pre delivery monkey.then babied by some poor sucker new car buyer who thinks he is the first to drive it!!!!this is exactly why I drove my new vr6 hard from the day I got it.whatever the booklet says is a load of b/s just to make you believe the car is a virgin.

Interesting link..... sums it all up perfectly.

No longer do they fire it up, but attach it to an external electric motor to spin all the bits and make sure its all good.

"'And instead of up to nine minutes in the hot tests, the cold tests take only around 2 minutes per engine."

I found this article a while back when researching bike engine run in's.
Whether you agree or not its an interesting read. http://www.mototuneusa.com/break_in_secrets.htm
