lol ok man, First of all, the passge in bold is absolutely incoherent. This is not a debate, thats the problem, you are turning it into some kind of debate.

According to EDMUNDS, there is no debate, so go ramble on somewhere else.

 

short answer....... No. And there are too many factors to discuss for me to even waste my time right now. Biggest 2 are probably weight and LSD though....

 

Ugh. So edmunds is completely full of crap then? No credibility?

 

ah, yeah, pretty much. lol, its not that they're full of crap, its just that Toyota and Scion PAYOLA their way into getting good reviews. You know what Payola is right??? i HAVE a Scion tc w/ TRD shocks and Eibach Pro Kit springs (same as, if not better than TRD springs)..... and it doesn't handle NEARLY as nicely as a new Si.

Skunk2 (pretty sure)'s Si won the skid pad challenge (beating the AMS evo, crawford Sti, JIC magic Silvia, Full Race 240, Chris Rado's TC, etc....) at Modified mag's Shootout. They won by a LOT. convincingly over the tc.

 

Can you not read? I quote myself...

"When people like edmunds state that a sc tc would lose against an si, they are wrong. But when they say something the community agrees with to back up a tc owners claim, they are correct.

Never fully trust testing made by companies. The professional drivers hired don't own the cars therefore have a limited amount of time to get "use" to the car they are driving."

 

I have no clue wtf you're talking about. First you post incoherent nonsense, then you become redundant quoting your own BS.

Since we're on the topic of redundancy:

"According to EDMUNDS, there is no debate, so go ramble on somewhere else"

Also, you do not own a Scion, stop trolling. You= the real .

 

I used to own a scion and im still helpful to many on this site.

According to one magazine there is no debate, since when is Edmund's (of all places to look) the end all be all of automotive information?

And again, if the tC does prove better in the corners than a base Si, you have proved that with x amount of money you can hang with a STOCK Si. Well, congratulations if that proved to be true.

But as far as im concerned, it hasnt been proven based on Edmund's. Infact, i would pull my sources from a more reliable place.

TRD is very conservative, not to mention the tC has the high center of gravity which can't be replaced with trd or any other suspension. Replace the top than it would be more competitive. Not to mention the LSD, powerband suitable for track and a more track friendly suspension the Si has.

Thanks for playing along.

 

And the help of a clutch, upgraded tires, suspension and trd supercharger if you actually read more than that on paragraph, that tC had all of what trd had to offer at the time to manage the 66.3.

Strut bar's barely make a difference, especially on their own.

 

Bone stock 66.1. Which proves the clutch, blower, wheels/tires barely made a difference.

So, stock for stock, it's only a 1.7 MPH difference; which I'm sure would easily be made up via springs/shocks/sway/strut.

Stock tC handles like ____. With the way my car handles now, it would easily make up a 1.7MPH difference.

 

Oh, and if you really want to go on the Edmund's way..

The Si is better.
Heres the full review...

The first acceleration run is worthless, nothing but front-tire spin and smoke. Easing up the second time around, we bog the engine, miss a shift, and turn in a quarter-mile time that could vote.

You would think we were trying to launch a nitromethane-spewing Top Fuel dragster, but instead we're behind the wheel of a 2006 Scion tC coupe that looks like it could barely chirp the tires.

Ordinary tCs do struggle to grab rubber, but this is no ordinary Scion. Under the hood of this tC sits a centrifugal supercharger developed by Toyota Racing Development (TRD). It's squeezing 7 pounds of boost into the stock 2.4-liter four-cylinder with the help of a revised air intake. Bigger fuel injectors and a remapped engine control unit (ECU) assure an adequate mix of fuel and spark while a TRD exhaust spits out the leftovers.

Still, it's no Hemi Charger, so we continue to rip it down the drag strip in search of a respectable quarter-mile time.

Oldest trick in the book
Superchargers are old, older than cars in fact. They work on a pretty simple idea: instead of relying on the engine to suck in its own air, you force-feed it with compressed air. By stuffing in more air, you can add more fuel and the result is more horsepower.

Sounds simple, but it's easy to screw up. That's why aftermarket superchargers rarely come with a warranty.

With TRD's setup, the tC retains its 3-year/36,000-mile factory drivetrain warranty as long as everything is dealer-installed, a 6-to-8-hour process by Toyota's estimates. Combine that with the $3,200 cost of the supercharger and you're looking at around $3,500 minimum on top of the tC's $16,200 base price. Do the work yourself and the warranty drops to 12 months or 12,000 miles.

Second time around
A few more runs and we're finally getting the hang of the tC's power. Its supercharged thrust is instant, so the tC takes a restrained foot to keep it hooked up. Even with our test car's optional 18-inch EMX wheels and Pirelli P Zero Nero tires (225/40R1, traction is a problem.

We shouldn't be surprised. Adding the supercharger gives the tC a solid 200 horsepower at 6,200 rpm according to TRD. That's 40 more horses than the stock tC and 200 rpm higher on the powerband. Torque is up, too, from 163 pound-feet at 4,200 rpm to 184 lb-ft at the same speed.

Not exactly Neon SRT-4 numbers, but they do stack up pretty well against the 2006 Honda Civic Si, which puts out 197 hp and 139 lb-ft from a 2.0-liter four-cylinder.

The TRD way
With so many aftermarket systems already available for the tC, we ask Gary Boler, business operations manager at TRD, what makes this system different. "We designed this system with three major goals in mind: maximum power, clean emissions and refined operation," he says.

Since there are aftermarket turbo kits that boost the tC's output by considerably more than 40 horsepower, we ask why TRD didn't go the turbo route. He mentions the tC's close-coupled exhaust catalyst that makes a turbo difficult, if not impossible, to fit. "We wanted to keep the installation simple for our dealers. Plus, a turbo generates a lot more heat under the hood."

We didn't need a smog test to confirm the cleanliness of tC's emissions. The system earned an exemption from the strict California Air Resources Board (CARB) making it legal in all 50 states.

Scion smooth
Other supercharger setups might deliver more power, but they would be hard-pressed to match TRD's setup for refinement. Start it up and you barely hear the compressor. Other than a faint flutter off idle and a couple of quarter-panel badges, you would hardly know there was anything different under the hood. Even the TRD exhaust is relatively quiet.

With no other driveline modifications, the supercharged tC drives just like any other Scion tC. It idles smoothly, builds power progressively, and would probably get decent mileage if we didn't have our foot in it the whole time.

TRD offers a high-performance clutch, but the stock unit handles the extra power just fine. Same goes for the five-speed shifter. If you have an automatic-equipped tC, you're out of luck since the TRD system is for manuals only.

The larger wheels and tires give our test car good grip, and the optional Hotchkis strut tower bar stiffens up the front end slightly. With the help, our Scion weaves through the slalom course at 66.3 mph. Fast, but not quite as fast as the Civic Si's 67.8-mph run through the same set of cones.

Last chance
With its big torque advantage over the Civic Si, we expect the Scion to be quicker in a straight line but the Honda has a couple advantages. One is a six-speed gearbox that allows it to run shorter gears to keep the revs up. The other advantage is the Si's standard limited-slip differential which allows the Honda to get its torque to the pavement more efficiently.

After a few more runs down the drag strip, we nail the launch and click off a 7.2-second 0-to-60 time and a 15.1-second quarter-mile. Solid times that are identical to the numbers we ran in the Civic Si. With a limited-slip splitting up the torque, there's no doubt that the tC would be quicker, but as of right now, Scion doesn't offer one.


The money matters
Being in the same drag-strip bracket as the Civic isn't a bad place for the Scion, but keeping a supercharged tC in the same price range as the Si isn't easy. Between the cost of the supercharger, installation and a handful of options, our test car has a sticker price well over $26,000.

With the Si going for a mere $19,990 for everything but a navigation system, $26K for a 2006 Scion tC Supercharged is hard to swallow.

 

Right. TRD has made springs so advanced they blow everything out the water. No use for coilovers in a track environment when you have trd there with their springs.

Even with your springs.sways, the tC has incredible body roll. Why? Next time your in your car, look up and thats part of it.

 

Sure.

The only reason I posted this thread in the first place was to see how my TRD tC faired against a SI.

From the research I've done, a tC with TRD suspension against a STOCK si would pretty be a driver's race.(Handling only).

And that is pretty much it......

 

Yeah if you have better tires and around 200hp...

 

 

who??

i think this is hilarious and pointless of a thread personally. but i have nothing else to do tonight.

 

lol we were simply on a mission to make this thread show up NUMBER 1 on google when searching for "TC SLALOM SI".

 

Congratulations, you succeeded.

 

^
lol. damn google.

at least you dont take things personally on here like most.

 

Straight answer..... NOPE!

 

how about this guys...my good friend just got a civic si, and i have a tc..i am installing my new front and back hotchkis sway bars in a week, im not sure whether to do trd coilovers, or trd lowering springs and sport struts (so any help with that would be amazing!!) im also getting a supercharger in the summer, sooo....when me and my buddy race a couple times, and when i drive his car, i will let you guys know, ok?



but seriously, i do need help with the coilovers and the lowering springs/struts, like which would be better for handling
