115/3484 Restoration

Post by NigelK »

Dear All

The restoration of 115/3484 is gathering momentum. The work is being done by Chris Marsh Classics near Chippenham (that's Marsh as in Marcos) with strategic guidance from Paul Lewis, former owner of the car and all-round top bloke. The bodywork was done by Colin Holley a few years back, so efforts to date have focused on gathering the required parts, and sending various components off to third party suppliers for restoration.

One minor hiccup has been the temporary "loss" by the couriers of the refurbished axle - this was delivered in error to a building site, and only recovered by chance when a builder noticed the Simply Performance packing tape on the pallet and phoned them up to check what it was. Fortunately it wasn't damaged, only a light dusting of sand...

CMC are currently completing the stripping of the original underseal before the body goes into their spray booth. The block has been dipped in Deox-C, shed an amazing amount of crud and casting sand, will shortly be sent off for machining, it looks in good shape so hopefully only a 30 thou overbore will be required so the new pistons will fit.

Just heard from LEDA Suspension that my Selectarides are now restored and fully functional (both hydraulics and electrics). Excellent service from Roger and the LEDA team, who provided an extraordinary level of technical detail during the refurb process and answered all my questions.

Pre- and post-refurb dyno testing results for the Selectarides below. One of the dampers was not functioning at all (the blue line in the top graph), as the adjuster had come adrift, while the other was not functioning properly because of debris in the piston valve. Post refurb both dampers are working properly and, critically, showing pretty much the same damping force characteristics at all four settings.

906 heads back from Hauser Racing today. Hardened exhaust seats fitted, plus 2.14” Manley Race Flo intake valves and Comp Cams valve springs. Heads ported and polished, and refaced to achieve 86cc combustion chamber volume for a 9.79:1 static CR.

The block came back from South Cerney Engineering yesterday, rebored to 30 thou over. They spotted some dimpling on the deck surface so 6 thou was skimmed off, necessitating a minor rethink of the head gasket selection in order to maintain static CR below 9.8:1.
