because the charger is still using crank power to turn it, which in turn is not being fed back into the motor and been vented, hence wasted power...

just leave the TB where it is, and get a nice size cooler like a Vr4 cooler and i bet u will hardly notice the acceleration when u let go of the throttle.
guy who lives near me done it to his car with standard boost and it still retained the standard boost when he put a spec front mount on, large surface area but a thin cooler with only using 2" pipes to plumb it.

thanks for all the help the idea of moving the throttle body will be the go but will moving it to after the supercharger mean that my supercharger is constantly spinning or something?

your s/c clutch is ecu controlled, from memory it something like 5~7 inchs of vacum, it will switch on, and after you back off it delays the disengagment of the clutch a futher 5 seconds, the reason behind this is not to over use and wear the s/c clutch every time you change gear etc etc

Well i don’t know what every one is talking about as i have a massive intercooler and heaps of piping for the front mount. Please see picture beside this and the intercooler goes to the top of the bumper.
I have an aftermarket pulley (Home made for extra boost and bigger than any aftermarket one you can buy) and have had no problems with coming on boost but i have a delay when coming off the throttle of about 1 second.
Whether or not the pulley has something to do with this i do not know but you can’t buy a much bigger intercooler than what i have.

So i can’t really see the point of changing the set up to the degree that has been said here. It may work but you might as well turbo as it will be easier and only cost a little more to do.

For the original guy wants to know where are you from? You might be able to come see mine or i can e-mail pictures to you.

comming OFF the throtle. Who cares about that its on that you dont want lag and that is only at low rev's. 5000rpm and above no problems.
Was bad and took corolla for skid last night.

what is the throttle responce like on a stock setup map gze? does it still have the lag after throttle off? is it really as bad as you guys are talking about? what about changing the top mount air to air, to a water to air i/c? would this be better than running the factory air to air?

It really is as bad as we say, and the only way to stop it is to move the TB, and then run a nice big BOV to evacuate the excess air that is between the TB and the SC when the throttle closes.

im sure any bov will do, there is no need for a big bov! the more air that goes out the bov the more u will have to build up in all the piping and intercooler, if u have a big cooler it will take a while to build pressure up again. all u need to do is vent the pressure the sc builds up wen it is spinning after the tb is closed.

throttle response is GOOD wen it is stock! only wen u put piping to a big cooler does throttle response become bad!

would changing the top mount air to air i/c to a water to air and leave it top mount help at all? say a legacy rs unit? that way the air will be getting colled better than the current top mount setup, and the piping will be still the same length so the throttle responce will still be alright.

any thoughts?

you would, but the heat soak would be heating the water, which is getting circulated away to the front mounted radiator for the setup, so gets cooled down anyway.
