Hi

I've a 2005 Scion TC

with K&N typhoon , DC headers, tri phase, Agency Power Crank Pulley + DC strutbar


I'm looking for more info to go for more HP but Naturally aspirated.

any suggestions?

thanks in advance

 

What is tri phase? I ordered the NST underdrive crank pulley and I will have it on my car by next week. I'll update then.

 

omg are you for real??

 

OK I looked up the tri-phase... I don't know what to say. I don't really understand how it works, and I don't know of anyone else who has bought it.

First off, do you have a manual or and automatic? A stock manual tC will have around 140whp (wheel horsepower) and the auto will have around 120whp. I'm not sure if you are talking about wheel horsepower or crank horsepower in your projected numbers...

The K&N Cold Air Intake produced 3whp and 3wtq as shown here https://www.scionlife.com/forums/vie...ht=intake+test

Your DC Sports Header produces 7whp and 5wtq as shown here https://www.scionlife.com/forums/vie...ht=header+test

So not including the "tri-phase", you are looking at having about 151whp.

There are two types of pulleys, lightweight pulleys and lightweight underdrive pulleys. ZPI makes a lightweight stock sized pulley and NST makes the underdrive pulley. Underdrive pulleys send less power to accessories and more power to the wheels, so you will see more power with an underdrive pulley. NST also makes overdrive alternator pulleys to compensate for the lost power to the accessories and lightweight water pump pulleys. Check out https://www.scionlife.com/forums/vie...ghlight=pulley

With intake, header, full exhaust, and pulley, you should be able to make it into the 14's with a manual... If you have an auto, then it will take alot more work to get there.

The point to all of this is, manufacturers will make claims that are not always dyno proven, so some numbers are vaulted. If you do some searching around on this website, you can find dyno charts for just about every part available for our car. Next time, do some searching and you will find what you are looking for and avoid getting flamed by some of the members here.

 

What is the tri Phase?

Like TTURedRaider311 said, unfortunatley you arent making anywhere near the power you think you are. You might be making that much crank horsepower, but its HIGHLY doubtful. The supercharger is forced induction and is only running about 220 crank HP. So to get 190 crank HP out of intake header and tri phase (whatever it is), I dont think will be happening.

Have fun on the endeavor of modding.

 

tri phase you know.wish to TRIpple your power

 

you can try doing a search and you will find a whole lot of helpful information on pulley's. i'm currently running NST's 3 piece pulley set and i love it. its a perfect product.

 

Hi

Maybe you're right but
here are the sites on the internet that I've visited to get those info

I will apreciate to get your reaction/opinion of what you think about it after chec
king those sites

thanks in advance

I've seen the numbers you quoted before, but like I said above, some of those numbers may not be dyno proven.

I see in your sig you want to hit the 14's... You are well on your way to that, I would add a full exhaust (ZPI, Draxas (my personal favorite), Creative Compacts, etc.) and a lightweight or underdrive crank pulley (ZPI, NST, etc.) The search button on this website is your best friend, there are many threads talking about hitting the 14's naturally aspirated, you should check them out to get some advice. Keep in mind, it is easier on everyone, including yourself, if you search for the information you want first instead of asking a question. Most of the members on here probably know the answer to your question, but few have the time to explain in detail.

 

tri-phase.you actually bought that crap.that thing is a waste.tri phase my azz

 

The numbers you see on those sites are generalizations and are most probably overrated... to say the least....

I sort of see the point to the whole TRIphase thing... but would rather go with a Emanage or something that allows real tuning control...

You most definately are not running that much to the wheels.... the stock tC runs like 135 to the wheels, plus around 5-8 with an intake, maybe 13 with a header/intake and if you push it with a good tune - 10 more hp by tuning it... you're most likely pushing around 155-160 at the wheels and possibly up to 190 or so at the crank... if it's tuned really well which I couldn't think that you could do taking into account mods and a general tuning device like the "Tri-Phase".

 

First and foremost, you need to educate yourself about your car as much as possible. Thats where you need to start.

After that, take a lond hard look at what you want to achieve vs. what you want to spend. Then consider how your mean to reaching your goal may or may not void your warrenty. Risk assessment ;)

Then, plan out how you're going to do this with mods. Bolt on or custom? When you think you've found parts you want, you need to educate yourself on what they do, how they do it, and wether or not they REALLY do what they claim they do. Chances are, someone here has been there, done that, and you could save yourself both money and hard lessons learned by educating yourself on said products.

Scionlife really is the Scion's foremost community for knowledge. Use this forum as a tool to help you reach your desired results.

Finally, do not believe everything you read. Especially from someone making a claim without supporting evidence. Like any other market, people sell products and services that result in no gain and money lost. IMO, this Tri-phase appears to be just that. A little snake oil for the tuner-noob if you will. There are no magic switches or amazing fuel additives bla bla bla, and you'll learn all about this stuff the more you read and learn.

Ignorance causes the most problems.

Good luck with your ride and tuning and welcome to Scionlife

 

maybe the numbers aren't dyno proven

but one thing is for sure

with this setting I've smoked 2 different Acura RSX -S and a 4WD VW VR6 a 6-speed Matrix XRS on 1/4 mile

 

The numbers are dyno proven




to be false. You will not get 10hp from an intake, you won't get too terribly much from an aftermarket header, and you definitly will not see any kind of gains from something like "tri phase" Did you order a Turbonator too? :p

In order to beat an RSX S in the quarter mile as an auto, you were likely racing someone who has never been to the track and is likely still learning to drive and doesn't know how to shift.

 

LOL

 

No way you smoked a decently driven RSX-S.... They are much lighter, much more powerful and with the 6 speed, a tight little machine... I have a co-worker who races his and can push 14.7-15.0 with just CAI and DC Header over and over again.

AS an AUTO.... There are tC's with EManage and all your little mods that can't break 15 yet....

You're going to hit a wall with the serious guys around here.... me included, who've studied and put time into understanding the tC's setup.... You can't just take the blue pill and get what you want to get.

All your little box does is change mixture and timing, to DEFAULT and AGRESSIVE tunes, based on a BASELINE dynoed car. It's super general, and not suggested for anyone who really loves their engine or its longevity. An Emanage can adjust the same settings, but tailored to your engine, your bolt ons, and your fuel.

Playing with fire and going cheap tends to end up as "Boom"

 

I was looking into getting a pulley and i was wondering is it reliable and how hard is it to install, and which one offers the most torque, i have an auto i was lookin at the nst or agency power

 

Oooooooooooooo
