Dommination of FI cars.

Hey Larry,

Lets see how everybody feels by August of 2008, by that time the sandbagging should be over..
Then they will see how it really is ? Please don't tell me that FI cars are now factored correctly, its a Joke... But I guess this is the only way to prove it... Larry, it will take years to even this move out @ 1-3 HP per hit... I guess they want us all to move to FI cars, hey its only money... Time will tell..... I do think we had too many classes,but not enough thought was given to the HP factors... Should be an interesting year on top of high gas prices and the cost of traveling....

Recommendation: give imput to NHRA to tighten up AHFS so it works faster or more often or at more places and EVERY bogus combination will be corrected faster as well as the FI cars... It is the right idea and based on real racing but just not effective enough yet...

A while back someone commented that you couldn't increase air flow in an FI unit. How about the fast idle control valve? On my bracket car thats a 3/4 inch o.d. air leak when activated. It could be activated with a switch. Do they even tech that? Sort of like pulling the line off the vacuum guage only with a map sensor to increase the fuel. Has to help.

Why do you want to increase the amount of unregulated fuel when it is metered and controlled by the injector rate? Also, a vacuum leak does not increase airflow; the airflow is controlled by the size of the throttle body.

The fast idle control lets additional air in down stream from the throttle body. The MAP tells the computer to turn up the fuel. More air = more cfm that isn't controlled by the throttle body.

At WOT, it will not make a difference.

I guess the man doesn't realize that at WOT there is no vacuum.
