Ahh i see, any side effects from this? I did ask someone and got advised against it with a charger. Really wouldnt mind doing the snip and cutting it off though.

 Sorry for the thread hijack 1982mk1, it seemed right at the time to ask in here.  :-[

side effects could be that the dump valve can't maintain enough air flow to keep the vacuum levels in the engine correct off-boost.  I know someone tried using 2 dump valves once to over come this.  Just caused weird running issues.

There's nothing to be gained here, at best it's a waste of money.

Ahh i see, might have to leave that scruffy T piece on for abit longer then. I dont mind mods that dont increase performance if they are abit more aesthetically pleasing but if its more of a head sore than a eye sore i'll live with the eye sore ;-)

So how do people get away with using a G60 throttle body?

G60 throttle bodies also have a boost return, its the same system just a different way of doing it. The only way to get a progressive throttle without the boost return valve I would have thought is having a throttle body before the supercharger that altered how much air intake the whole system could have.

I have never really paid much attention to a g60 throttle body up close, next time i will.

Throttle body before supercharger sounds very complicated  :)

Would that not be damaging to the Charger in any way?

One minute full boost and the neck a sharp stop to all Air.
Or even at 4,000rpm how would the charger cope with minimal air.

I don't see how it could damage the charger, it just wouldn't be pumping very much thats all.

My mate fitted an eaton m45 to his old MGB with a carb on the inlet. Seemed to work alright. granted it's a different charger and not a TB but the theory is the same.

That is good then, in my head i somehow managed to think it could have been.

 But i still think it would be an extensive amount of work.

I have now seen 2 G40's running the g60 throttle, both high powered.
I wonder what made them decide to follow that route

most of those big American supercharger stacks seem to use a similar arrangement too.  With those big "fly catcher" throttles on top of the supercharger to stop air getting in.

I guess they want the g60 throttle body because it's bigger.

Do you know the size of the TB on a standard g60?


At what point would a G40 throttle become restrictive though?

I tried to find out and i asked mad mike but he didnt get back to me.

I guess if a G40 is 45mm maybe a G60 is 65mm?
