Cumulative HP gain?
Approximate cumulative HP gain?
Custom tune - around 15hp
Magnaflow cat-back exhaust - 10hp
K&N air filter - 3hp
Mid America Motorworks Mass-Airflow-Sensor Housing - 9hp(they claim)
So, added up...looking at about a 37hp net increase?

@unihusker
all those little horsepower "upgrades" are not upgrades at all. Here's the thread where it was explained to me- https://www.corvetteforum.com/forums...or-92-lt1.html
It costs real money to get any noticeable HP increases from an LT1

You may have gained a few hp from what you've done, but certainly not 37 hp. Instead of guessing, why not put it on a chassis dyno to find out?

You can't "add up hp" like that. Doesn't work. First, the advertised gains claim UP TO xx HP. Meaning, on a highly modified motor, where the item in question has become a meaningful restriction, changing to their part may gain the number that they're claiming. On a STOCK or stockish motor, where the item in question is not a meaningful restriction, the power gains will be somewhere between nothing and meaningless.

??? not sure what you mean....from that article
Baseline
"Accustomed as we are to 600-, 800-, and even 1,000hp C5s and C6s, we were primed for disappointment when Anti-Venom proprietor Greg Lovell strapped our virgin '96 to the shop's Dynojet chassis dyno for its first pull. We were pleasantly surprised, then, when the car registered a respectable 263.3 horses and 291.5 lb-ft of torque at the rear wheels, not too far off what one might expect from an early automatic C5. After a backup test produced virtually identical numbers, we unlimbered the tools and got to work."

per this article...http://www.superchevy.com/how-to/vem...p/viewall.html
they're added up net gain the same way I'm speculating what my net increase end result will be. So why can't I apply using this method as well?

Sorry as everyone is telling you. It does not work this way. Such as filter, 104 fuel, spark plugs, wires, dist, MAF housing & such.. NO gain mods. If this were the case. what I listed would make 30HP in your eye's or reading material. 1.6 rockers, Gears, Cam & tune and so on will result in the power add on's you are looking for.

Whatever they did, here is the bottom line: they spent ~$300.00 to get 13 hp. For that same amount of money, you could buy a cam, that would give you an honest 30hp or more. Diddle-f'ing around w/mass air meters, filters and mufflers is a waste of $$ if you're goal is HP.
