Run in procedure for Boss 290

She's arrived. GT(white, blue stripes).

With 290 kw under the bonnet I know she will take it but at 1000 km on the odometer, I am not keen to push limits.

I have stuck to the 4500 r.p.m. limit for the first 750 km and have pushed to 5500 r.pm. and she's done just over 1000 km.

What is the engine red line?

What are your thoughts on when I should push past 5500 r.p.m.?

cheers

Re: Run in procedure for Boss 290

I pretty sure they rev limited to 6000rpm. I 've got a BA XR8 ute with 1900km on it now and was told to drive it hard from the start, but not to thrash it! I've taken it to 5500rpm about 6 times now but generally take it 4500 - 5000rpm in 2nd & 3rd 5 times out of 10. I believe that you've got to drive them hard for them to go hard! That's what I've done with all my cars. But I reckon you shouldn't tow anything for 3000kms.
Cheers TS 50

Re: Run in procedure for Boss 290

Thanks TS 50!

5500 rpm is not exactly standing still especially from 3rd upwards!!

The rev limiter on my last car (XR6T) had a severe cut in when I hit the engine speed limit. The first time it happened it scared the you know what out of me.

Have any of you guys had similar experiences with Boss motors??

cheers

Re: Run in procedure for Boss 290

Thanks for your replies.

Just got back from Rainbow Beach (nice bit of road) around 5 pm. It's now 7.20pm and I'm still smilin'.

Rev limiter kicks in at 6500 r.p.m. (oops) The "bounce" is not as severe as the T and there was no drive line/transmision noise as I have experienced in the past when I hit the limiter.

The car just keeps getting better each time I drive it, and now I have had a chance to drive at speed, the difference between the XR6 and GT is noticeble: starting with the brakes, then suspension. Not to mention the note..... sweet. The GT has a "wall of torque" directly proportional to the planting of the right foot. I feel the GT is definitely quicker in third gear (onwards) highway passing than the T. In a word "Awesome"
cheers

Re: Run in procedure for Boss 290

As far as running in, I have always been told the most important thing is not to keep the car at a constant speed... and the obvious, not doing flat-floor starts at every take off.

Re: Run in procedure for Boss 290

I have been giving mine heaps from day one, running in procedures these days isn't important as it was years ago, as long as you give them a bit of everything, like loading them up in higher gears, giving them a good rev and varying rpm whilst cruising along. ie, using a lower gear for a while. The service manager where i did my apprenticeship for Holden, favourite saying was "run 'em in, run 'em hard" and all his company cars used to fly !
