Any ideas?

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.

Thats fine POLOMON, im as interested as you are! 

[hayesey]

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.

[Justin14100]

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.

[djtez]

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

[hayesey]

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.

[hayesey]

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

[djtez]

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


At what point would a G40 throttle become restrictive though?

[Jezza-7]

Drag cars use them same thing as well.

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?
