Hey so i've heard it from my tuner before, seen mention of it in street magazine and once more in motor (in reference to a new clubby they had on the dyno that put out 220rwkw) but couldnt find any topics on it

New engines supposedly put out less power until they've "loosened up" whats the go with that? Is there more resistance and friction before they've been driven a few thousand k's or something? In general how much less power would you expect out of a freshly rebuilt rb compared to one rebuilt 2000 or 5000 k's ago?

Cheers

ah ok cheers mate, i've put 2000km's on mine, did all the bedding in things, going to assume the engines well and ready to go back onto the dyno then

that is a question for you to ask your tuner and discuss about it.

yeh car scored a bit low on the dyno (about 30kw's lower than average), just wanted to make sure it wasn't the engine that needed loosening up as he suggested

suspecting possible cat collapse now.. hoping for anyway, failing that theres something shagged somewhere

      Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!

      Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure

      A Brumby would probably fit a big metal toolbox in the back... this is how it begins

      Picked up a new OEM boot seal for the MX5 today as the old one got ripped a bit by me being a idiot by seeing if I could fit a large metal tool box in it, it didn't fit, and ripped the seal with the corner of the tool box I am still waiting on time to get the cams and new balancer installed, as well as the repairs to the boot Time will not be an issue soon though

      I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?
