in the video he posted, it dident jump up till right at redline. maybe the supercharger just turning harder, idk
Its a roots blower, It's pushed air. Your not going to have the same psi from car to car, pulley to pulley.
Just went back to the 3.4. I had 5 psi on the stock 3.8. With the 3.4 i have 7psi at WOT. I have ported blower, lim, tb, 1.9 rockers, headers, full exhaust.
Excessively ported blower?
I dont know, its not excessively ported its the same i do for all my other customers. Before the ported blower i had the 3.4 on there, 10 psi of boost max. When i ported the blower, went to the stock 3.8 pulley and observed 5 psi. This weekend i installed the 1.9 modified rockers and it had slightly more pull but not that noticeable. Yesterday i put on the 3.4 again and even though it only has 7 psi versus the 10 before, it has way more power like i can light the tires up from a 20mph roll. This is keeping in mind that i dont have a tuned pcm either so i know there is more to be had.
Btw, the rotor coating is good in tact also.
at the top of second at 6k i saw 8psi. top of first it was 7.
back on the stock tune shifting at 5500rpm i see about 6 at the top of first.
the consensus is...........there is no consensus...all different
A tune is done by adjusting the valves in the muffler to change the exhaust note.
No no no...that's the nitrous.
