My new ve 4-1 header
I just got this header. It was prettier but because its mild steel it doesn't have a nice finish anymore. We'll see how it does when i dyno it.
OK first thanks to Bruce over at pro-tech for making this header and getting it to me in the amount of time allowed. Also thanks to Cory n ser007 for letting me use their stuff to tune and the tuner Shane for doing a great job with our cars. Now on to the header the overall gain is good but not what was expected from me or a 4-1. I guess its just hard for my motor to make good power and i believe it was since i did a rebuild with a de 8cwc although most would say that the de crank is better. Also this header should do better with a motor that is set up right. Previously i dynoed tuned my car with fuji header and n1's and it made 192.7whp/143tq. With the Pro-tech 4-1 bolted on it made 196.5hp and with the tuner tryin to tune it made the best of 198.1hp/146tq. Here a picture of the graph to show the gain from this header vs. the fuji.
