will procharger D1SC work with vortec after cooler i've got?And Will it be allot more money to change over to procharger than just bolt on T-trim? Also are the crank pulleys completely different because im about to buy custom pulley for $275 dollars to work with ATI superdamper. BTW Call911 CR is 8:1 is this to low?

 

The aftercooler from Vortec is specifically for the Vortec blowers. I suppose with the right fabrication anything can be done, but it was not manufactured to do so. I would go with a good FMIC like I am running if you go with an ATI blower. I believe the T-Trim is about as much as the D1SC. Call Bob at EPP and tell him CALL911 sent you. He will give you the best deal by far out there on both the ATI blower, and their FMIC. As for the pulleys, I am not 100% sure, but I would guess you need the pulleys from the company that makes the supercharger. 8:1 is pretty low. I would say the lowest to go would be around 8.5:1. I am running 8.8:1 and mine is good to well over 25#s of boost.

 

yeah 8:1 is pretty low, there are import kids running 35 psi on 8:1. I am running 9.1:1 on my 355, which still gives me pretty good power out of boost. I am looking to run about 17-18 psi

 

9.1:1 is a good ratio. It should be good for 17-18#'s. 9.5:1 is where it starts to limit you to safely run more than 17#'s or so.

What is the parastatic drivetrain loss of a LT/LS T-56? I'm making 800hp at the crank and have yet to drive the car. I'm also wondering what kind of power I will make to the wheels.

 

800 at the crank would yeild somewhere in the 650 RWHP range I would guess.

 

why so much loss?

I don't under stand how this makes any sense.
some people say m6 = 16% loss and i don't know how true that is, but lets say you don't modify any thing but engine. why would the same m6,rearend,drive shaft loss so much more power now.because 16% of lets say 500fwhp is much more than 16% of 300fwhp?

 

I don't know "why". I just am basing that number off of numerous cars I have seen do an engine dyno, and then later had a chasis dyno done. I can't provide any more information other than saying, it is what it is.

 

call911 I didn't mean to pointing finger at, you i just never could under stand why? btw thanks for all the good advice.and to anyone else that gave there .2 cents.

 

Its all good. Cars loose power due to the transfer of power from the motor through the transmission and driveshaft through the rear to the wheels, and then to the ground. But I think you are trying to understand "why" the loss is that much, and I don't know the answer to that.

 

blown cars also loose as much as 80-100hp on top of the drivetrain loss due to the belt and how hard the motor has to turn in order to turn the blower. the biggeer it is the bigger the loss. So if you putting down 650 through an auto and a 12 bolt, add your drivetrain loss and then add your blower loss and that is what your motor is actually seeing.
