Re: Engine mount ala Porsche

Before the work on the engine frame I used a decibel meter app on my iPhone to record noise in the cabin and with the windows shut I was getting high 60s (67-68) at low running speed and 70-75 when revving over 3krpm I drove to work yesterday with a decibel meter app running on my iPhone and here ar...

Re: Engine mount ala Porsche

update on NVH - after about 20 miles it looks like the harmonic vibrations are gone. I don't know if the A frame or engine mount location was responsible but aside from volume and pitch changes, the painful bass vibrations are gone.

Re: Engine mount ala Porsche

and now complete! I've only driven it a mile or so but it's really nice to drive, the most startling difference I've noticed so far is the low speed control and setting off, none of the standard imp bite and bounce (which I never noticed until it wasn't there). When you lift the clutch it really ste...

Re: Engine mount ala Porsche

yes it's a GRP construction with lots of corematt and weighs in at around 6KG. The arms extend inside the cabin and are glassed in and around the rear spring turrets. If I put enough weight on them I can lift the nose of the car in the air off the axle stands which are about 6" ahead of the rea...

WFD 577H

a quick thought, does anyone know any details of my Davrian prior to my and Myles Castaldini's ownership? It occurred to me tonight that I have zero idea about history and it would be great to know. Having dug the GRP about, I have concluded many years ago that it was smashed up pretty badly at one ...

Engine mount ala Porsche

In an attempt to reduce NVH in my dav I'm fabbing up a rear crossmember structure to replace the single dangling pivot. I googled a few porsche pics and noticed they have a very different approach to engine suspension to that on imps and davrians. It's bascically a wide bracket solidly mounted to th...

Re: vibrations/noise

Ordered a set of 8 x m16 rod end bearings tonight to make up a four link bulkhead mounted engine brace to replace the standard a frame. Will post pics as and when. Should be lighter than the a frame and I hope way quieter.

Re: Steering column?

Two UJs upgrade now underway. I've realised the best place for the wheel is probably appearing from the centre of the dashboard. It's also about an inch closer to me as it suits my preferred driving position in my daily Audi A4. Is a nearly vertical wheel desirable? I think yes and perhaps we don't ...
