For your information and interest, we have listed some sample power figures for the various TVR Speed Six engines on this page. Some of this data is for the standard factory specification engines, and there are also sample outputs for a couple of modified engines.
Latest power graphs that we have to share with you are courtesy of Sabre Tuning's dyono (Sabre are on 07969 165334) The cams and redesigned billet finger followers are ours at RND Engineering, with 360 degree oiling, GT Valve springs, and an oil feed to the back of head. As with all our components and engine packages, technical and cam timing specifications were supplied by ourselves, with the work on the customer's car being carried out by Lloyds Specialists Developments in Warminster (Lloyds are on 01985 998082).
The power figures below come from Rob
from Oz who managed a creditable 313.3 at
the wheels horsepower with our GT cams and our parts on a TVR Tuscan.
- Rob's figures are at the wheels, not at the flywheel, and are
measured at a steady output state. See also our page on 'Dyno Facts
Fictions' elsewhere on this site.
