Realistically, what kind of power gains can be seen on a stock SS LS-1 with the following.....

I have already installed:

82MM SLP Intake Manifold
82MM Throttle Body
Magnaflow Cat Back Exhaust with Cut-Outs

Wanting to install:
Headers

I know it's not much of a gain, but I am looking for some realistic numbers.

I do plan on installing a ProCharger at some point in time.

 

Realistic numbers from the mods that you have:

82mm TB: 0
82mm Intake: ~10
Exhaust: ~10-15

Headers: ~20-30

The stock TB flows more than enough to satisfy an otherwise stock motor, you need to get into a bigger cam or better heads before you'll see any benefit from that TB. LS1's love exhaust side mods, so you'll get a good increase with headers.

 

Nice it.I think This will be public.
