does it matter how big the m/a sensor is compared to the throttle body like if use a 75mm throttle body and a 90mm m/a sensor would it cause any trouble

 

I might be corrected, but i dont see where it would make any difference

 

The mass air should always be bigger than the tb, so they would work fine together. But neither one should be used on a stock setup. Whats are the other mods?

 

331 stroker, holly systemax II intake, 185cc afr heads, 30# injectors

 

well the rule of thumb is that the MAF should be equal to or larger than the TB, generally speaking the TB should be the same size as the inlet on the upper intake otherwise a lip will be created , interfering with airflow. what intake/ motor setup are you running? a 90 MAF will be okay with a 75mm TB but the sensor needs to be cal'd to the injector size your running. give more info on what your setup is and what your trying to do...k

 

i must type slow....

 

do you guys think this could accomplish 400hp?

 

80mm would probly be big enough

 

what cam are you using? what compression? it should make about 400

 

i'd say with a 9:1 or 10:1 compression, 345 hp
