Right, sorry. I finally understand. I read your posting too fast and overlooked the detail.
and by 400HP more... what are you going to do to it? did you mean 40 more/ with the waste gates somehow?
You put a solenoid valve on the line that goes from the manifold to the waste gates. Right now, the waste gates are set for 12 psi. If you turn the valve on and off in a controlled sequence, it fools the waste gate into thinking it has 12 psi, where in fact you are going up to 20 psi or higher. It just takes programming one of the spare outputs from the ECM.
The tricky part is making sure it has enough fuel to go with the added air. I know I need another fuel pump.
The setup I am running was tested at Banks on a 360 cubic inch sbc and they took it up to 1050 hp. I’m sure this 383 can do the same. The rule of thumb is 50 hp per pound.
I think I mentioned before, I’m just curious to see if I can beat the Camaro I’m towing around with this thing. The Z is going to be in the high 10’s with different tires. It’s best time so far has been 11.01 @ 130 mph, but that was with a 2 second 60 foot.
I’m just playing here, the Hoe is my daily driver first and foremost, so I can’t get too crazy with it.
