well that'* possible when you have a car that has 1/3 the volume of a real engine
As for laminar flow, think of it as a measure of how smooth the flow is. Our MAF sensor (mass air flow) needs to measure how much air is moving past it, but for it to do the job right, the flow needs to be very smooth and steady - laminar. If you throw something in the intake (Tornado) that'* meant (or heck, not even meant) to create a 'vortex' or anything of the sort, you're chopping the air up, and taking away the smoothness. Under those conditions, our car'* MAF'* will have a hard time reading the true mass flow rate, which in turn tells the PCM that the engine isn't moving as much air as it thinks it is. End result? Lower performance.
And it'* this way for pretty much any car with a MAF... some cars have less trouble with it, others have more - but it'* not really good at all. On the other hand, I have talked to people who had good results using a tornado on a carbureted vehicle.
have fun with your 95, and don't be afraid to ask questions -
