Procharger buddies please help . At a loss here.
I am saying you do loose 3 square inch of area. That is a lot of area to loose. I think 3.5 inch or 4 inch piping would be ideal. 3.5 inch pipe would be the same area as the twins actually.
To match the area that was lost.
I am going with air to water, that will be in the same place as my twins. 800 cfm air to water twins.
The 4.5s are not bad either. They are not. I know they are only good for 800 rwhp though.
I added a fmic this winter, better catback , 3.4 to a 3.0 pulley , washer fluid to 50 50 m1 and water .
I brushed off the 572 number but then two days later he dynod a 13 grandsport auto car and make 360. So the dyno seems right on.
