One PSIG is a big deal when the atmosphere is only about 14.7 PSIG before the TB.
A larger TB assists but it can not be too big unless serious programming is done on the engine controller. Rob and I tried a PAIR of TB's on a DCI and it sorta worked but the engine would have a continuous hick-up during normal driving, ok on WOT but I could not get the computer to accept the fact that more air was available at any throttle setting.
Enjoy, only 19 days till election, finally cant wait. Woody
Would I not be correct in saying that the pressure before and after the throttle body when the car is running is below atmospheric pressure?
