Ignition HP gain

[PhilipMc]

Recently I adding a few upgrades to my Ignition. I changed the stock coil pack with a MSD 1. I changed the copper spark plugs for iridium and changed the stock wires with Magstar racing wires. How much Hp do you think I added both at the wheels and in the engine. And my engine is a 420a with a K&N air filter but the rest is stock.

Why didnt you use stock plugs for your car?

 

[PhilipMc]

Because the stock plugs were bad and the new plugs are performance and are oversized 8.5mm wires

Probably not enough worth measuring. If anything, your maybe back to what the horsepower when the car was new.

 

[PhilipMc]

No theirs gotta be some gain all 3 of those parts are performance

 

[92AWDHX40]

What kind of performance are you looking for from those items?

 

[PhilipMc]

Just general HP and better low end acceleration

This thread is awesome!

Dude, your upgrades likely have not gained you anything. The plugs no, the wires no, the MSD is the only part that has a glimmer of hope towards increasing your car's horsepower, and it probably doesn't but if it did a dyno couldn't tell the difference.

 

[PhilipMc]

Ok could someone please tell me why because all I hear is no and theres no supporting evidence

No no, here's what's going to happen. YOU'RE going to tell ME why the answer should be yes with supporting evidence.

Changing your spark plugs to different varieties of expense, when simple plugs work great will not net you any power. It could make you faster by lightening your wallet.
Upgrading to "super duper 8.5mm amazo!" wires also won't do much for you. Wires don't increase horsepower unless there was something wrong with the old ones. I'm not saying that you shouldn't get some wires, it's a personal preference - but still, no one gains power with spark plug wires.
As for the MSD ignition box, well I kinda want one.. but I certainly wouldn't fool myself into thinking it made my car faster just for having it.

The term "Performance" is a marketing tool to separate you from your money.

Riddle me this. What kind of gains were you expecting from plugs?

 

[skatershawn]

what makes the plugs "performance" to you? Because they have some rarer precious medal compaired to copper, and an excellent advertising team along with the folks at autozone trying to upsale you because theyre trained to? Or because they cost more than the coppers?

I feel there is no such thing as a performance spark plug that will magically give you a gain in HP. Nothing more than the restored HP that was lost from the other srt being old.
The only time you need to "upgrade" your plugs is when the current set you have are with holding potencial gains that colder plugs will help you with, due to them being hotter and possibly causing knock.

I am trying to figure out if the OP is being serious or not...

OP-Did you expect to gain hp by adding more spark to a stock N/T engine?

 

[PhilipMc]

Ok the spark plugs are iridium which is better than copper because it ignites the fuel better because iridium allows it to work better with less voltage to get the spark. The spark plug wires are over sized and have less resistance than the stock plugs which allows the electricity to move more efficiently and the Coil pack is made out of better materials and windings to create a better spark.

 

[skatershawn]

I correct my previous post about needing colder plugs as hyou have a n/t. But none the less you would only be gain the lost hp from the old plugs.
IMO the best gain you'll receive from the plugs and wire is a more efficent burn in gas, giving you increased gas milage, but still wouldnt be much to really notice.

its good you can read that stuff and believe it, thats where they make their profits, but its all sugar coating.
You wont gain anything more than you would with copper plugs.
When it starts to become effective and you would possibly start seeing gains is when you start adding more fuel and air. Till then theyre just expensive plugs. Sorry.

 

[GsXdSmKingGsX]

You would be better off grounding everything for a hp gain

So what? I mean that information you just posted is extremely generalized and without any basis.

So I'll say it again, so what? What's this imaginary spark improvement doing for you?

Oh right. It's igniting fuel "better".


btw, I'm not trying to thrash you but I am trying to encourage critical thinking.

 

[PhilipMc]

You guys keep saying im going to regain lost hp or whatever but my engine is not that old, only 88k, and right after i bought the car I got a tune up to change all these things with stock parts. Now its 5 months later and now that i have some money i changed the stock parts (which btw were in good condition) 5000 miles later with these parts and felt a significant performance difference.

5000 miles later meaning i got the tune up 5000 miles ago.

 

[92AWDHX40]

What did you feel? In performance was it faster, better accleration, a better launch? From your mods on your car?

 

[PhilipMc]

not much from a stand still but if i was going 10mph to 50mph and I laid on it, my car accelerated a lot faster and also climbed to higher speeds like 80mph+ faster than it used to. It used to get to 80-85 and climb really slow but know it climbs at an increased speed at 80+

 

[92AWDHX40]

oh i see.

 

[PhilipMc]

yea so do you still think i didn't add any horsepower

like obviously its no turbo kit but i mean i was hoping for something

 

[jls_frog]

The gain you feel is probably in your head, at least with the iridium plugs you wont have to change them for a while, my 03 eclipse had them and they are good for 60,000 miles according to Mitsubishi.

 

[skatershawn]

Do you have any physical proof of these gains?
To me it sounds as if you are feeling the improved burning of fuel, not added power.
A more efficent burn will smooth idle and acceleration, and have a possible gain of a fraction of a horsepower.

But to end this, we cant really answer that question for you anyways.
One, its beanch racing and is against the rules.
And two, there is no real way for us to know the gains it provides on your car with out doing a before and after dyno.
Sorry again!

Whats beanch racing?
