cheap HP

anyone know how to increase my horsepower by just a little bit by doing really cheap mods to my engine? now i have a few add-ons here and there. but like everyone else, im always looking for that extra hp here and there. everylittle bit i can squeeze out of my motor will make me happier. if you have any hints and/or tips please let me know.

it would be helful to list the mods you already have....and by the way you can get some octane boost....my buddy told me you actually can tell the difference....but if anyone disagrees let us know...

nevermind...i see your mod list there...

there are a few free mods that can get you sommers around 50 more hp, according to a couple websites.

if you actually try octane booster, tell me how it went :p

guy i know kept talking about having a bottle of NOS in his car and lead me to believe it actually had nitrious. it was really NOS brand octane booster... :D if he was still around i would make fun of him some more about it :D

well good news, ive use the prestone, 0-60 octane booster. 2 bottles for around 10$ at wal-mart. result? = no real noticable increase in performance or horsepower. a touch more pep in accel. but top speed and hp gain? nahhhhh..... so.. i will keep looking.
thanks.. anymore tips?
-p.s. ive heard of turning a screw in the intake manifold of the 420a n/t which allows more air into the intake, which in turn increases hp by a fraction? anyone Know this to be true?

it would be really helpful to you and everyone else if you look above a couple threads up on for tips and info, these questions have been discussed countless times. search engine on this forum is also very helpful.

i have a 4G63 can't really tell you what else to do. however consider you have a 420a, there really isn't much more to do other than intake and exaust for the amount of money you're looking to spend. you'll prob get more response from other people telling you either slapping on a turbo or selling the car and get a gst/gsx which costs about the same. you might find that response unhelpful however, it's true.

perhaps some Naaawwz will get you somewhere, altho it might require some degree of tune-up of your engine first.

goodluck!

thanks.. :)

np, make sure you check out www.vfaq.com too. chances are you'll find most of your answer there.

have fun.

damn i was really hoping the octane boost would increase the power....yea i seen those gay ass NOS bottles....my cousin works at a detail place and a lot of ricers go in there and in their car they have those bottles glued on their pillars...funny shit

There are quite a few things you can do some of them hurt driveability though. One of the main things is if you have a dremal, some sand paper, and time. You can port and polish well just about every thing. Your throtal body, intake manifold, exaust manifold, and your head.

Then you can hook up a imrpoved grounding system, Check that out here (diffrent motor but it still applies)

There are some throtal body mods you can do on this page,

The PCV to breathers mod,

Then you could buy a intake spacer (they are like $50) and disconnect the water line hoses on the throtal body. That will keep the intake much cooler and keep the air passing thru it cooler to.

Anthor really big thing you can do is weight strip it, every 10lbs you remove is the same as adding 1hp.

There are lots of things you can do if you have the time and the ability.

Wouldn't suggest porting to someone who didn't know what they were doing. PCV valve either works or doesn't, I don't see any performance there. The water lines that go to the TB don't affect intake air temperature, so they don't affect performance. Sorry, fast and cheap don't go together.

and the weight thing is every 100 pounds get you 1hp which equals like a thousandth of a second in the 1/4 mile

1stgenrocks you must stand corrected.... 100lbs = 1/10 of a second......

ok i just knew it wasnt 1hp for every 10 lbs

I dont see how the water lines dont heat up the throtal body. Its used for in the winter when the tb is cold to heat it up. Its the water from the engine. So isent that hot?

As for 10lbs = 1hp, + or -. It is a mathmatical fact and i will prove it to you right now. (you can test it to if you dont believe me [to figure out power vs weight ratio its the hp of the car dividied by the weight])

lets take a car with 250hp that weighs 2,500lbs its power to weight ratio is 0.1 that meens it has 0.1 hp for every pound.

now lets take a car with 350hp that weighs 3,500lbs its power to weight ratio is 0.1 WOW! it also has 0.1hp for every pound

The 3,500lbs car is 1,000lbs heiver and inorder for it to have the same power to weight ratio it has to be making 100 more horse power. That meens 1,000lbs = 100hp. If you drop 2 zeros from them bolth BAM!
10lbs = 1hp

It is a fact not a theroy

That is horrible logic. If you don't see why-- I recommend re-taking math. That said, you might notice that I didn't deny the ESTIMATE of 1lb=10hp. I didn't say anything about that in my reply, so stop defending yourself.

FYI, the reason you are wrong is because you assume everything is linear. Also, power/weight ratio doesnt have anything to do with how much 'power' you gain from taking away weight.

3 parts
1. Yes you diddent say i was wrong about that, but others did.

2. Weight is a constant. If you took away all friction, then it would take the same amount of energy to go from 0mph to 1mph, as it would to go from 1000mph to 1001mph.

Take a space ship for example, That would use the same amount of energy for every mph it gains. Because its accelerateing the same amount of mass.

Friction is the growing drag on the car that causes you to take longer to accelerate on the top end.

So weight is linear.

3. I dont quite understand what your talking about here
"Also, power/weight ratio doesnt have anything to do with how much 'power' you gain from taking away weight."

When power vs weight ratio is a mesure of how many horse power you have per pound. I diddent say you gained any power (If you though that for some strange reasion), But you will gain power per pound. So you will become faster.

As Jake and I found out today by getting a ECU out of a maunual gs eclipse your rev limiter is set higher. Jake was actually able to get the wheels to squak comming out of second while shifting it manualy. If I had an auto N/T I would definetly pick one up. as for getting one for FREE go take a walk in a junk yard thats what we did haha...3 for the price of 1 today boys...

yea i beat on my brothers car way to fuckin much!!! anyways that was a good trip up there man... fun times!!!

The general rule is that it takes 10 HP to go 1/10th quicker or 1mph faster, on a car that weighs about 3000 pounds. 100 pounds is also good for a tenth. So taking out 100 pounds is like adding 10 hp. The thing is on a turbo car, 10 HP is very easy to come by. On a NT, its a different story. But even if you take out 500 pounds and go 5 tenths faster, who cares, the car will be a noisy, uncomfortable POS. :D

I woudlnt quite call it a fact though, there are many variables it depends on. Its not that cut and dried. But its a good bench racing standard.

Yeah your very right about that GSXracer. There are alot of veribles for the track. But it is a fact if you had no friction on the car (it might be a fact with friction on the car also, i dont want to say it is for sure. Untill im able to prove it is). Because of friction just looseing some weight wont help as much on the top end (maybe it will?) because you need that raw hp to over come friction (mainly aero drag). But it will help some, because your mass doesnt change just because your going 130mph (witch goes back to my point maybe it does have the same effect on the top end i cant be sure yet though).

But light weight has other advantages like every hp you gain goes further. Just look at the Lotus Elise it has 118hp but it goes 0 to 60 in 5.2 sec. Now turbo that car and give it 218hp, That would be pretty fun :evillol:

I agree with everything you said in your reply, sorry I thought you were saying I denied the 'fact'.

The reason that it's not a fact, and is just an estimate is because it depends on the weight of the car. For a normal DSM, it may be 10lbs to 1hp. It's definately not a theory though, and you can't prove it using power/weight ratio because a heavier car will 'gain' less power per 10lbs than 1hp. Definately not a constant, or fact. I realize it's not gaining any horsepower, I'm just quoting 'adds horsepower' because that's what it feels like, or seems like on the track.
