Mike,
Thank you, I do appreciate. I post another vid tomorrow, I did a mistake with reconnecting the leaking engine mounts in the system, but figures are somewhat similar and the more speed the engine revs the less vacuum I have so the problem remains the same....GRRRRR !!!! Finally the turbo may be in good condition (it may !!). Aside from the vacuum pump, I can't see what could be the culprit, connections are limited to the minimum. Vacuum pump, hose to the TCG vacuum port, hose from the out port of TCG to the Turbo Vacuum Regulator and that is all. Hoses are leak free, TCG is new and TVR don't leak either ! Do you know if there is one or two vacuum source (compartment) in the vacuum pump, i.e. one for the brakes and another for the turbo vacuum system ?
I look forward to see your video ! Thanks again Mike for your help...
