Run In for Track Driving

[NTY]

Hi all,

What is the recommended mileage for a new noble before it is suitable for hard driving on track?

I'm aware factory manual says running in is 1,000 mile, but is it adequate for track driving? Any comments?

[Ash M400]

I ran mine in up to 1600 miles.

I think you will find Noble will say it is perfectly ok after 1000, I am just cautious. I slowly increased my revs after a thousand miles from 4000 to 4500 for the next 200 miles, and then up to 5000 and so on. I did not hit max till just over 1600 miles.

I would also consider changing the oil every 4k or close, for what it does it is not very expensive.

[Mr Noble]

The running in process that Ash adopted, although exceptionally good for the engine, was only adopted due to the pace of the car and the intimidating feelings that the pace can generate in a driver.

Basically, Ash was too scared to use any more revs!!

I've just had a new engine fitted to my car, and before I ran the car on the track I did the following.

1) Run in on low boost for 1K miles.
2) Complete engine check, new oil and upped boost to normal levels.
3) Drove the car to Rockingham.(100 odd miles)
4) Caned the hell out of it !

It was fine, and I experienced no probems.

As a rule of thumb, I always change oil and filter before a track day, and replaced brake pads which were passed 50% used. Also give the car a check over for ware and tear.

I ran over 50K miles on my previous engine, which included many track days and lots of driving to and fron france (Noble is faster than BA!)

Would add that the 1st 1,000 miles should be driven with a good variation in the rev range. Sitting at 70 in 5th on a motorway for a day is not the way to do it.

When we've had new engines built for rally cars you can't get that sort of mileage on them to break them in. 150 - 200 miles at a test venue up and down the box, a few quick blasts at the end of the day and then off to an event. Mind you most of them are taken out and stripped down after 500 stage miles as a matter of course anyway

Are there any DATA for all this advice?

Thanks guys I'll probably run her in progressively to 1500 miles before tracking.

Noble is my third car and hence it's going to take me a while to get to 1.5k. Running in is a painful process

Btw, I can't see the oil filter from the engine compartment. How to access it?

[JLSELAN]

Access to the oil filter is through a hole in the undertray. Ideally, the rear of the car should be in the air to get to it--using either ramps for the rear wheels or a jack and jack stands.

As I understand it it's important to use the engine to some degree during run in in order to get a good seal between piston ring and bore. Failure to do so can result in loss of performance and more oil use! My approach was to warm the engine up nice and steadily then not be afraid to use the throttle through the gears. Not absolute mash the pedal to the carpet and redline it obviously and certainly not labour the engine in to high a gear.

Once I'd got the 1,000 mile service done I was away

(There is a school of thought that the 1,000 mile rule is cobblers in this day of fine manufacturing tolerances anyway)
