Morning folks, Nice dryer. I can't see much problem with shaving the mount in this case as it looks like an OEM mount as opposed to a backyard purpose built one. It doesn't require much clearance in that area - 5mm is ample as the mount & the turbo will move in the same plane at all times - you do get a small amount of flex thru the manifolds but it's minimal.
If you're worried about the integrity of the mount post shaving I'd suggest that you weld a small brace on the inside between the vertical plates or an easier method to brace it is to use a decent size bolt eg 8mm thru either a round or square tube that's positioned flush between the inner vertical surfaces - either method is acceptable for racing engines so rego shouldn't have a drama with either. The position of the reinforcing brace would be say 25mm i.e. around half way from the bottom of the mount. Any time I've been required to shave a mount I always repaint it etc to make it look like it's not just been hacked with a grinder - if it looks like it's been hacked then it probably has been in the minds of most engineers. Actually from looking at the photo, I'd be more worried about the clearance between the static part of the mount (i.e. below the insulator) and the housing when the engine moves at WOT on the mounts. Hard to say from the pic how much static clearance there is there but it needs to be at least 10mm. Heat will not be a factor in this case as far as I could tell from the pic. Have fun with it, Regards, Terry -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Mick Ralph Sent: Wednesday, 14 June 2006 5:26 PM To: [email protected] Subject: Re: shaving the engine mounts? Adam I would be inclined to get out the grinder in this situation. But then I'm usually a bit quick to get out the grinder so.... usually I ask here first.... so I guess ur on the right track My issue here is with how much clearance do u actually need. If for example the mount on the other side was a bit soft (old or new?) then u would probably need more clearance on the turbo side. Having seen a lot of engines misfiring over the years, and seen what it can do to the clearances we are talking about here my GUESS would be at least 20mm clearance. having stuck my neck out I would also imagine that Terry or Errol et al would have some sort of formula for working it out properly Cheers Mick PS Aren't digital cameras a blast ----- Original Message ----- From: "Adam Jackson" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, June 14, 2006 4:46 PM Subject: Re: shaving the engine mounts? > Jeff, > > I can't see how there would be.
