Complete Bolt On list and rwhp expected from them?
I was very interested in having a list at my disposal - does anyone have one of these? Perhaps the price and possible rwhp gain too would be great!

I started a list for myself. Click "Mods Chart" in signature. Although, as big as it is, it's very incomplete. No hp gain for most items, and you can't necessarily go by the hp gains that are shown. The prices are (for the most part) complete and accurate.

1. Prices are always changing, different vendors charge different amounts. Plus something like a catback can vary between $200 and $1000 and still show the same gain.
2. There's thing called diminishing returns. Essentially ALL advertised HP gains claimed by manufacturers are compared to stock (and still often highly inflated or unlikely).
There simply is only so much HP available from an LS1 before the internals (heads, cam, etc.) become the restriction.
In reality a full bolt on LS1 will usually see somewhere from 340-360rwhp. This variance is due to dyno types and corrections factors. This can easily account for 20rwhp difference even from the same car.
Auto's tend to make less rwhp, although the engine will be just as powerful.
Sure if you are after a dyno queen then lightweight drive & propshaft combined with skinny lightweight alloys and tyres and low friction lubricants can net you a few more rwhp, but in this case the engine won't actually be producing any more HP.
Now as far as diminishing gains goes just look at all the claimed HP gains from all the bolt on's and add them together.
Example: 2000 LS1 manual 6 speed, ~345bhp SAE Net and ~300rwhp SAE Mustang Dyno.
-Ls6 intake = 15rwhp
-ported TB = 8rwhp
-lid = 15rwhp
-air filter = 2rwhp
-smooth bellows = 2rwhp ( )
-TB-bypass = 5rwhp (again )
-Pulley = 10rwhp
-Caback = 10rwhp
-!cats or high flow cats & mid pipe = 10rwhp
-Lt headers = 25rwhp
-electric waterpump = 10rwhp
These are all figures I seen claimed for these mods. And I'm sure there are still more mods I've missed. But we are already up to 112rwhp extra
So with bolt on's you can get 412rwhp SAE on a Mustang Dyno or 440rwhp SAE on a Dynojet. And claim to have a 470-500bhp motor.
But saldy this is total BOLLOX!
To see that kind of HP you'll need either a wild cam as well, or for most a decent cam and heads.
So remember the claims are only ever over stock.

Put down a solid 350rhwp/tq
Just installed ls6 intake so now I'm looking for a solid 360rwhp/tq after tune.

not to mention some people consider different things bolt ons..like I consider heads bolt on because its not hard to do them. I also think nitrous is a bolt on too because its easily installed.
author of this thread, dom a lot of research. These cars don't have "stages" like other cars get. That **** always annoyed me, I have a stage 3 audi a4, wtf would that mean?

Arguable items come in the form of non engine components such as gears, stalls and suspension.
