Ok im trying to get an exact number of the horsepower gains from the following mod's

1) RRM Piggy Back ECU
2) 2.25 Magnaflow Catback
3) Headers + Downpipe with 2.25 outlet
4) Ground wire kit
5) spark plugs


Combined i think im looking at 40HP???? (Ball park figure)
If anyone has some of these mods put some input in.......

--------------------------------------------------------------------------------------------------
Im trying to obtain at least 160HP from these mods.... Looking for a good HP increase without buying a T-25 intercooled or non, their still outta my league in prices

 

ive got the magnaflow catback with a RRM test pipe.. i felt a nice little push to it. i dont know exact.. but id go with around 20HP-ish..

 

every car is different, All depends on how it is tuned and what gas you are running etc. It is impossible to give definately numbers.

 

no way a catback and test pipe will give u 20hp. i say 10 at most. an dlike 5 to the wheels. u don't get good gains from this motor untill u boost it. prove to me that u have 20hp from catback and test pipe with a dyno sheet. no way

 

LOL

dude, lets be honest, if all you got going is a catback and test pipe, you may have 5whp added, maybe............and i'm skeptical about that.

guys always overestimate gains with simple bolt ons. are they worth it? sure, but don't talk about power until you start adding some real mods (tb, ported im, cam shaft, ported head, pistons, header, etc etc)

 

the piggy back ecu will increase tourque and horsepower by a percentage, not a given number. So the more mods you have = more horses. The combo of the piggyback, headers, and exhaust will give you a real nice push, but I doubt 40 hp, especially at the wheels. As for the spark plugs and wires, I've heard that they smooth out your idle and acceleration, but hp gains are minimal if anything. Again, that is simple what I have read on these boards.

I do know that the magnaflow on my car is fun and made me really happy. I suggest the exhaust and piggyback first, but that is just the route I am taking. Good luck.

 

Not sure what kind of gains you get from that. I have:

- Intake
- Header
- DP
- Cat-Back

The gains are nice, a difference but nothing extreme. Still need to add TB, IM, Green Psychos FR

 

look at the dyno'd lancer list in my sig to get an idea.

The problem with "I want exact numbers" is, always has been and always will be, that the effects are cumulative. So, while on a stock lancer the piggy may give 15hp/9tq on its own, and the test pipe gives 2hp/-5 tq on its own, the cumulative effect may be something like 18hp/5 tq.... it's hard to say, is what I'm getting at.

GP is right that everybody overestimates the gains from simple bolt ons.

Spark plugs don't actually produce any additional HP once they're broken in (which only takes a few miles, really). hotter and colder plugs can support various timing and fuel management changes, but the plugs themselves don't actually produce power.
Grounding kits.... long story short: make your own for $30 and don't expect much more than headlights that don't dim when you're rolling down the windows, and maybe a smoother idle.
header will show decent gains, DP will take them away, opening the exhaust will actually hurt your performance- until you start opening the intake side and working the fuel management.

For the very basics, I would start with:
*header
*short ram intake
*Piggy if I never wanted to tune my own car, or add mods that aren't made by RRM AND supported by the tune in the piggy- otherwise I would learn to tune the eManage (which, BTW is what I did)

So that's a nutshell answer. spend some time in lancer engine tech to get LOTS more info. Yes, it's a lot of reading, but frankly if people are too lazy to do the reading then they get what they deserve- wasted time and money and a car that's slow as hell..... my $0.02

 

Why does everyone forget the most important part of modding?

It does not matter how many peak HP you gain with a mod.

Unless you want a trailer queen so you can go "if have 200hp!", you look at the real stat.

The shape of the curve.

Who cares if my axleback only added 1 hp? If the HP curve is larger, that's what counts.

OK, I'm done lecturing.

 

you're preaching to the choir. The problem is that the curves from these mods are shot to ****. Look at the hp/tq curve on the dyno'd lancers list. my TQ starts high and stays high- that's indicative of good power across the band. The HP climbs pretty steadily to the peak at 5300RPM or so. It's like that because I've carefully selected my mods to give good power across the band- peaky power is useless on a track or at autocross.

If you look at my buddys hp/tq bands (with his axel back, test pipe, no AC or power steering, and generally a mishmash of mods thrown at the car) they pretty much follow each other- which means bad power delivery until you reach the RPM peak.

And that's what's been shown when the exhaust gets opened up- loss of torque, which means a powerband that LOSES AREA UNDER THE CURVE. Integrating 1 hp over the length of the curve gives way more power than integrating 1 hp over the last 1000 RPM of the curve. Opening the exhaust generally only gives that 1hp gain at the top....

alright, I'm beating a dead horse

 

i agree its about the curve...dont be concerned about peak hp to much... just be worried about the power that is at your disposal...a well tuned wide powerband will own a car tuned for peak power... ive seen it first hand, two civics, relatively same amount of mods and money spent but the other one had it by three cars cuz he researched and new what he was doing when he put together his mod combo...

good luck withur 40 hp.. lol

 

you realise that this would then put you in the ralliarts hp range and should then net you a 1/4 time in the 15s depending on the shape of the curve? thats not going to happen. look at what times ppl are getting with simlar mods, they are still in the mid to high 16s.

^^^^ Ooohhhhh..... denied- you didn't actually answer the guys question Plus, we've referenced him to other threads for more info, but we won't let this one die.... hey DJ, why not lock it down

 

We just need one big "hey n00b - here's how much HP you can add!" thread.

As per Kris' request...
