I have a BA3000 placed blow through. I think the car was draw through at one time. Everyone seems to think blow through is the way to go with a procharger. The BA5000 in a 3 inch tube is only good for around 600 wheel hp. So I'm at the point that I change everything to get the BA5000 into a 4 inch pipe and larger throttle body from the 3 inch inner cooler or just place the BA3000 in to a draw through configuration. Is there really a noticeable difference in the amount of piping from the MAF to the throttle body in a draw through application?
