The performance chip always cracked me up. You could gain so much HP or whatever just by adding this damn chip lol.
Wha? These work with the right chip. My neighbour has one in is F-250 Super Duty diesel. He can also select different "stages" if you will, depending on what he's hauling.
Some of those are based on claims from the manufacturer of those parts. K&N claims a 5-11HP boost. Some header companies claim up to a 40HP gain.
Heck Ford claims I get a 15hp difference just by using premium gas (365hp) versus regular unleaded (350hp)
Some is marketing and Im sure some has merit. You can probably get 100 extra hp from a ricer motor but it will come at a steep cost (turbo charger/super charger, new cam, new heads, headers, cold air, etc etc)
If the vehicle is intended to be run on premium, and it isn't, power can definitely be lost. Common knowledge.

Sounds optimistic, but the point of adding or swapping to performance parts is to add power. Only the dyno knows the real numbers.

Chips are real. Not the $20 ebay junk, but they can make a substantial difference,. They are basically a fixed version of what handheld tuers or laptop programs can do.

Traction is always key, that's why the fastest cars you can buy from a dealer are all AWD with the McLaren 12c and 911 gt2rs being the only rwd up at the top that I can think of....
Ferraris? Vettes? Many of the much smaller exotic companies?
HP to weight is where every car begins. The more weight a car has the more power it needs to compete, more brakes to stop, and more suspension to manage the bulk. Colin Chapman made it his motto in regards to making cars faster-"add more lightness".
Dumbest thing I've heard is someone said that HP to weight ratio being the key to a fast car was the dumbest thing they've heard.
Weight, torque, and traction ARE the keys.
Torque is just a function of horsepower and rpm. Traction is a given, otherwise you just said the dumbest thing you've heard is are the keys which is kind of odd.
Back when ricing cars was hot, I heard a guy talk about the power he had thanks to all the add ons. He started with the factory horsepower. Each part he added promised a certain amount of HP increase. He'd add 5 HP for the air filter, 40 for this, 10 for that, until he added up to about a hundred HP more than factory.
Another claimed HP to weight ratio was the key to a fast car. Guess the transmission and other parts plays no part in speed.
That is how the high performance magazines of my youth, 1980s, would indicate gains with modifications. With dyno numbers with proof. I notice it is still the case.
other wya around, horsepower is a function of (torque x rpm)/5252. dynos measure torque not horsepower since horsepower is a calculation.
HP = (T * rpm)/5252
T = (HP *5252)/rpm
Potato is potato. Torque is a function of horsepower; horse power is a function of torque. You're right about dynos measuring torque, but that doesn't have anything to do with a function being a function. If torque wasn't a function of horsepower, horsepower wouldn't be a function of torque. The calculation has to worth both ways or it's not a function.

Do you know anything about performance? HP is for braggin'; torque is for draggin'
