Splatt,

I know my customer was somewhere in the elevens....dont remember how deep in the elevens.

Concerning the post highlighted above the throttle response from the 90 mm set-up is half the reason to purchase it. Its just the opposite of what you described above. Once you drive your car with a 90mm TB you will never want to look at another 78mm TB ever again. SOTP is up big....It will feel like you picked up twice the 20-25 ponies you see from the swap (typical results from my ported set-up).

Im not exaggerating....talk to anyone that's experienced both.

Regards,
Tony

Think AIR valve....no airspeed needed to atomize fluids....volume of air is all we are concerned with here. The TB opening simply provides a source of air for all the much smaller intake ports....thats where the airspeed will increase as the cross section drops immensely. You want the opening and plenum of that intake as freeflowing as possible.
