What is that?? Help me I was thinking SRI by Injen but idk yet!?

No such thing as Cheap & Performance in the same sentence...FYI.

Gotta PAY to PLAY.

 

^ correct. An intake,header or exhaust will only net like 4-6 hp tops unless you get tuned. the best bang for your bucks is a turbo kit. your not going to make anywhere close to the power of a turbo without a full motor overhaul.

 

Cheap, fast, good. Pick two

True lol I ment like what the best mod to start with lol I just got tein sprigs.

 

Plenty of guys have bolted on parts and seen substantial gains. Tuning always helps with supporting your mods to get you there but isn't totally needed until you do more than bolt ons. I think this is my third post today about smartest first mods and I'll say it again. A good fitting cai with name brand filter, the Dezod header and a properly sized s-pipe are a great way to go. Keeps the cel's off and should see an easy +15whp at least. That's being pretty modest, you might see more. I know header is good for right around 9whp alone with stock intake and s-pipe.

 

I am going to add NST crank pulley to this. If fact I would do it before CAI or exhaust. NST pulley frees up already existing power where as CAI and exhaust you will loose back pressure which will result in a loss of power. But if you just want it to sound cool do a CAI and exhaust ultimately its your car and you do it the way you want.

 

You won't lose power with the correct intake and exhaust. That's just silly.

 

Best mod = high performance driving education class and track time.

 

IMO the best mods to do first are the ones that will make the biggest impact and then slowly work your way through the list of more minor upgrades.

With this being said it's difficult to make an appreciable gain in power without laying out some big bucks, so I'd start elsewhere.

Two good places to start are with interior or suspension. With less than a grand you can make the handling if your car feel completely different with some new sway bars, or you can upgrade the audio system or add some neon accents to the inside.

All of these ideas are mods that you will feel the benefit of every time you turn the key

 

Seen or felt? There's a difference.

It is possible, and more likely, to see a loss in power somewhere in the power band rather than a gain from just bolt-on's, no tuning. It doesn't matter which brand. I'd like to see the before and after dyno results (same dyno, of course) from a third party (not the company selling the product).

 

whiteline rear sway bar. best "bang for the buck" mod for any fwd car. by the by, I've been running an "ebay" intake and header ($130 together) on my Xb for over a year, with increased power and no negatives. I even have a whole thread on it.

 

Measurable gain (dyno results) or feel?

 

Raced a similarly modded xb with "real" parts(intake/header), we were dead even. The driver mod could be brought into this, but a 30 pull doesn't really require skill.

(on a closed/sanctioned circuit)

If that isn't a testament to them...then what is?


Still sticking to my guns on this one, on a fwd car, a rear sway bar is the best upgrade you could do.

 

That may be good enough for some, but that still doesn't show any measurable gain. There are plenty of factors that come into play, which include the driver's skill, shift times, car component maintenance (is the car taken car of or beaten on), amount of gasoline/items/extra weight/driver's weight in each car. I'm talking about a straight up measurement. If you can produce the same result 100% of the time, which dyno results of the same car, before and after modification, will often show, then you will have something more than just conjecture. When it's driver vs. driver, there are too many variables that are used as a crutch/excuse.

All I'm saying is that we get a lot of "this feels like more power" on these types of forums, rather than "here are the results of said modifications showing a measurable gain".

I haven't been contesting anything about the sway bar. Going AX or Lapping you'll notice a difference with that modification more than anything you put on it that isn't forced induction.

 

Nope, this was an actual test of a car equipped with ebay parts, vs a car with "high end" parts. same cars, same mods, dead even.

I never said it "felt" more powerful, all I said is it was dead even with the same car, modded in the same way in a drag race. No missed shifts, no launch to worry about (30 roll) no vehicle problems from either.

You can nitpick the results all you want :D

Again, on a closed circuit.

If someone feels like paying for a short dyno session, I'm happy to dyno my xb to see what it makes at the wheel!

 

I think you're misunderstanding my argument. If you read my earlier posts, I did mention that it doesn't matter which brand mod you end up putting on the car. My point is that you will see little to no gain with bolt on mods (no tune) and in fact will most likely lose horsepower somewhere in the power band. I wouldn't say any of this if I hadn't experienced it myself and done my research.

There are plenty of forums with neutral party (non sponsored) dyno sheets showing little to no gain from bolt-on parts without tuning. Realistically, on average if you were to see any gain you'd see 1~ whp gain per modification (that all depends on the part, what engine, current outside temp, height above sea level, etc. you get my point).

 

It's simply unwarranted to say "Oh, slap on these 3 parts and it will net you 15 whp, no tune." It just doesn't work that way.

 

First test: grab a friend and a bag if dog food and go for a drive.

Second test: leave the friend and the dog food at home, go for the same drive.

Could you tell a difference? Well ditching your friend and the groceries is the equivant of 15 hp (give or take depending on your friends dietary habits).

Unless you are the type that worries about spitting seconds on hot laps, than minor performance mods are going to leave you wanting more bang for the buck.

 

Christ.

You're missing the point. I'm not even sure if your comment was for or against what I posted.

MEASURABLE GAIN. You know.... SCIENCE? You cannot simply bolt parts on and say, "Okay, now my car's horsepower is 200 hp, since the ad said it gives me +10 for the header, +5 for the exhaust, and +5 for the intake. You know because my baseline is 180 hp." and expect that to be a legitimate assessment.

You didn't add any fuel or change any timing on the stock ECU. And, since the stock ECU makes adjustments under strict parameters, it will most likely not produce more power due to those limitations.

For example: I know I had an increase in power after the turbocharger was installed and tuned because I took a baseline measurement on the dynamometer and then a measurement after the install and tune on the same dynamometer to find a measurable increase of 140 whp.
