Tom,

Thanks for the offer to help.

I want to add some electric blowers to the induction system of my drag race
car. I want to be able to ventilate the induction system to keep it cool
before racing, then add some air pressure, hopefully, to increase air flow
into the motor.

I have a sketch on my web page: www.cmc.net/~xero. Sketch is called EEI.jpg
(Electricaly Enhanced Induction). This illustrates my current system except
I have added blowers where the induction system makes 90 degree turns into
the engine compartment. You can see the car at www.fordmuscle.com. Click on
the feature 'The Mouse'.

I need to find a way to measure the minute amounts of pressure I hope to
create at low speeds, untill the system intakes can take over and force air
into the motor.

I would like to recreate the effects of high barometric pressure, which
really increase power. What kind of pressure are we talking about with
barometric pressure.

The Blowers are rated at cfm at certain static pressures. How does sp
relate to barometric pressure. Are they close in values?

Anyway, I am dealing with a lot of unknowns here as you can see.

Hope you can help me out a little.

Thanks
John
