HI. I bought a scion tc back in 2005 and recently I install an TRD exhaust and cold air intake in which it should help the car run faster but I couldn't find a slice different but I experience the losing performance.. This sound so weird right.. My Tc is an Automatic or is it that's the reason why you don't fix up your automatic car:-(.. I test drive my friend scion tc 2007 and it run great and his car is an automatic as well and interm my car should be fast bc I have extra performance stuff added to the car.. So i took it out to the auto repair and found out that the strut has oil and it been leaking plus I need an Alignment.. So my real question is if my car have an Alignment problem plus the strut is leaking oil, is this the cause of my car losing horse power?... I try to race against my friend and found out that not 3 but 4 I got smoke LOL.. I'm not into racing and I just love the Tc model... so can you please answer the following question

thank..

 

what's your question? I couldn't find one, it was like playing "Where's Waldo" with your post.

if it's about why your car is slow, it's because it's an automatic, and the TRD exhaust adds no noticeable gains, and "an intake" doesn't do anything more than make noise. Show me timeslips of proven performance from minor bolt-ons and I'll show you money better spent elsewhere, like tires.

Put your original intake back on and sell whatever piece of garbage you obviously attached to the engine in hopes it'll make your 120hp car faster. Your car right now is barely faster than a base-model civic. If you want the car to go faster, either have a reputable shop install a turbocharger reliably pushing 10PSI for about 4grand, or take that 4grand as a down-payment on a trade-in for something fast.

 

its cause you got an auto! like otocan said sell your exhuast and intake and get a turbo and then you will love your car. if not keep those blot on and go for a show car not a speed car cause bolt on wont do anything to the car. or just trade in your car for a 5 speed!

 

I get so sick and tired of this "your slow because you have an auto"!! GIVE ME A BREAK!!

 

Improper alignment and leaking struts have no effect on the engine's power.

 

you must have an auto huh? i'm not saying cause you got an auto your slower but when it comes to our cars yes. autos aint slow its just not as fast as 5 speeds or 6 speeds. cause i came name alot of autos that will rape our cars. i was just saying in our cars.

 

but improper alignment has an affect on your speed

 

you might be right i have to check my alignment i never aligned my car after i dropped it cause it was pulling to the side or whatever might have to check it out.

 

I don't know where to even start here. Auto or 5 speed...who cares this wasn't even part of the ?.

As far as your leaking strut.....you blew it replace as a pair or full set or go to TRD or coilovers if your car is lowered. However this has nothing to do with how fast your car is.

You mentioned something about smoke and 3 and 4 which made no sense can you clarify please?

The 07 against yours has I believe a 1 hp gain....not enough to matter.

 

You can leave the exhaust if you like the sound. I have the TRD and love the way it sounds.. but you arent gaining any power there.

For the intake, it will gain you nothing. I did some work for someone and they gave me a k&n (which of course came back off when it broke the bracket). I ran it for a while just to dress up the engine bay and sound different (Which really was a bit too loud). But, there was no difference in performance with or without it, which I expected. Some actually report a loss in performance. Either way it is not worth spending money for.

Alignment will not make you noticeably slower.. I dont know where anyone got that idea. Yes, it may hurt traction, but if you are scooping enough to actually notice the car is slower, you must have one duck footed car

Either you just expected huge gains and got nothing, which is why you feel it is slower, or the intake hurt performance.

If you want real performance gains on almost any newer car, then you arent going to get it cheaply. Manufacturers these days are trying to market on the best performance they can get while keeping economy in check, emmissions in check and overall price in check. They are pretty good at squeezing the power they can out of the car. Our stock intake, for example, pulls from about 1 foot away from where a CAI pulls from. And the metal CAI tube will heatsoak more, so after sitting still idling, you performance will most likely be worse.

An SRI... well, that is amazing marketing I guess It pulls hot air from your engine bay as opposed to cooler air from the fender.

Thing is, neither will help you. If you want to really feel this car change in performance for a reasonable amount of cash, look in the handling dept. You can make this car a pretty good handling vehicle for relatively cheap. For other gains, you can either buy a lightweight flywheel (doesnt change power to the wheels, but allows the car to rev quicker) or start looking at FI.

 

Try to toe-in your car and see how fast you go down the line. Most likely he isnt toed in though

 

its not ur losing power but maybe your wheels arent displacing the power correctly or fully. alignment shouldnt matter..take out your intake and see tthe differnce..and is it full trd exhaust or trd muffler because a muffler isnt really a perfomance upgrade by much

 

you could be getting used to the car? when i used to race my truck everysetup (most of the time) seemed to get slower after a few runs but i was actually getting faster. Anyhow you mods dont make anypower and the intake could actually be costing you power. BTW i had an 06 and now have an 07 and i can feel the diffrence it is faster.

 

I think the car feels quite a bit more responsive off the line and during WOT with aftermarket intake and exhaust. I have compared it back and forth between stock and those two addons a few times and came to the same conclusion each time. As far as the auto barely beating a base model civic, my friend has a 99 civic si with intake and sadly he cannot keep up with my auto tc, which he hates to admit. That means pretty much nothing, as yes, our cars in automatic or manual form are not fast cars, just pointing out the poor example given by Otocan.

 

how would you feel your 07 is faster then your 06 its just a 1hp difference aint it?

 

He knows it is 1hp different so he thinks it is faster. As far as I have seen or read, it has the same times all the way around, so the power band is not shifted or wider (which is the only way you would feel any difference).

People also slap on a louder intake and think the car is faster as well

 

Hey! The extra noise from my CAI makes my car faster. It has to do with the low pressure area created by the higher decibles. The sound waves traveling out from the intake create a vacuum of sorts which then drag the tC. Kind of the same concept behind behing theoretical "gravity drives."

But with sound....or something....

 

The bark is always bigger than the bite...

 

and why is this thread in the suspension section...

 

look at the dyno from toyota of th e06 -07 the 07 has a flatter torque curve and its measured based on a sae corrected dyno (diffrent method) so its actually like 10 horse across the board
