Hello Bugsy

Nice project. What condition is the bottom end of the block. If it hasn't been rebuilt proceed with caution. It very common with these mods to blow the bottom end out.

This car, I've only just got and I dont have any history on the motor, but all compressions are even, old pressure is good, and the motor is ultra smooth and quiet. All the mechanical side of this car is near perfect, s**t even the gearbox and diff dont leak oil. I feel confident it can handle a mild boost of around 5-6 pounds

I know what you mean. I thought my engine was good. Same as yours but a PI ran like a Swiss watch. 40k on the clock. I thought it just wanted new gaskets. How wrong was I. All bearings was down to copper and some mains was past the copper.
All sixes when on choke start at 2000 rev this is what drops the bottom end. For this reason on my TR6 I on have the choke cable going to the MU and not the throttle bodys I control the revs on my foot. The PI has a special twin choke cable.

I know CW was looking into supercharging back in the early 80s. I don't know how far he got. Also my memory isn't what it was, so it could have been turbocharging rather than supercharging!

Cheers,
Mike.

I'm sure I read something somewhere about turbo or supercharging a big six. Think they were planning on using MG Metro Turbo carbs, can't remember much more.
Interesting project, I look forward to reading about it.

I allready have a mate building an alloy intake plenum to bolt onto existing "S" intake maniflod in place of existing carbs, (didnt want the hassle of trying to build whole new manifold), Ive got a 6 rib pulley already mounted to a Triumph harmonic balancer. These superchargers are pretty neat as the charger is internally bypassed so they have an electric clutch on front pulley, so with it setup I can run on motor as normal, and when boost needed just switch it on. I plan running just 1 single 2 inch SU carb infront of the supercharger. I think that would be easiest to setup and tune.

That would be ME!

*waves at anyone who remembers me*

Unfortunately the car was a victim of circumstance and had to go, I do still have the proposed engine in the garage. Pity.

Anyhoo, hopefully I will be back in the 2000 scene soon, and the turbo trummy might yet live.

Very interested in this project.

Is there any system for ignition retard under boost?

Mike
