No, what is illogical is you coming to this board filled with people looking to modify their cars and telling them that modifying their cars is a useless, endless endeavor.

$7-12k to get to 12 lbs/ horsepower? I have a suggestion for you: Go read the ____ing board before you come here telling us how much money we're going to have to spend to get a set amount of power. Here, I'll make it easy for you:

In that topic there is a nice man selling one of the first production turbocharger kits for the Scion tC. It purportadly makes nearly 300 wheel horsepower at just under ten pounds of boost. So, at 34% of your stated cost we'd be getting, conservatively, 10 pounds per wheel horsepower. Thats 17% more than you guessed. For 34% of your projected cost. Sounds like your figures were a little pessimistic.

Over 100 models? Is that right!? Tell me - what kind of car can get me Toyota quality and refinement, with all the features I'm used to in the tC, and a similiar positive response to modifications. Oh, and I mean new.

HAHAHA! You come here - to a Scion board - and suggest a turbo rotary!? What are you smoking? Have you looked over why Mazda no longer sells turbocharged rotary cars? Maybe because they got their ___ handed to them in warranty repoairs because the damn things were so unreliable! Going on RX-7 boards, I see people bragging about 87k and 100k miles. What a complete joke. I'm not going to buy a car knowing that it's unreliable and that I'll need a new engine in fifteen thousand miles. Sorry, thats why I bought a Toyota.

Do yourself (and us) a favor and never come back here. You may just avoid making an ___ of yourself again.

 

Very true. You cant compare actual HP gains for different engines. Its the percentage gain you are looking at. Not sure which camaro he was talking about , but lets assume it is a 5.7L 300 hp engine... a 15hp gain is a 5% gain. A 15 hp gain on a 160 hp scion is a 9.4% increase. As you increase the air into the system via an intake, exhaust, FI etc you increase the fuel proportionally. So you are effectively increasing the power by the same percentage minus the efficiency losses in the system. A 15hp increase on a 300 hp engine is really not much at all, while the same increase on a 160hp engine is definitely noticable. A good example of what I am talking about is estimating a turbos power addition. 7psi is a 47% increase over the normal 14.7 psi atmospheric pressure. This means that 47% more fuel needs to be added to keep the AF correct. Now ignoring efficiency losses that means 47% more power. We all know this number will be much lower due to compressor efficiencies etc. not being 100%, but you get the general idea. This means that 7psi on a 160 hp engine will add less HP than 7psi on a 300HP engine. The percentage is what you need to compare. Ok... i have stuff to do, and I'm acting like mr wizzard, so I will stop now

 

EXACTLY! I just had to explain to a friend off mine the other day why I would wan't to install springs. She was just puzzled and was like, "all of that work and money to look cool?"

It took a bit to explain to her I get the most enjoyment out of building it. Taking it apart and actually installing the mods. I have this car and I work on this car as a hobby. This is my art!

 

I simply can't bring myself to spend that much money for so little in the way of "seat-of-your-pants" improvement. Where you start is usually a pretty good indicator of where you'll end up.

 

Yes, a strong bottom end that can take a good amount of modification. sounds like a good starting place to me.

 

I plan on getting the DC Sports exhuast for my fiance's tC. Doesn't it come with a silencer?

 

ha! well done. but i'm thinking i'd like my tC to be a bit quicker. i'm not interested in relation to an M3, just in relation to how it is now. still $900.00 for that gain is not the way i'm gonna do it.

 

Well this is all at peak. I'm more interested in what kind of gains these mods got at around 2-4000 rpms. What I like about AEM/DC is that they go for the middle range whilst other companies concentrate on raw hp numbers. Since I drive around 15-3500 rpms that's what I'm interested.

Then again, that means I'm not going for that header. It seems the axleback DOES in fact add hp. Very heartening!
