Here are the dyno results on a 2005 Scion TC NORMALLY ASPIRATED..
The 2005 Scion Tc had an ARC intake with WR Race Header and a Precision Exhaust.

THIN LINES = STOCK MANIFOLD + ARC AIRBOX + PRECISION EXHAUST + WR RACE HEADER
THICK LINES = WR MANIFOLD + WR SECRET WEAPON INTAKE + PRECISION EXHAUST + WR RACE HEADER



We dyno'd the intake manifold and noticed that the car wasnt getting enough air from the ARC intake system..

We then changed out the ARC intake for a WR Secret Weapon Intake.

The only change is the WR INTAKE MANIFOLD and the WR Secret Weapon Intake System.

We feel this manifold will make even more power and torque on a Forced Induction Vehicle.

 

finally a dyno....now how about puttin it on a boosted tc for some other results?

 

were is the baseline before the manifold install?

 

i might have to get one of these...

 

thin lines...

 

interesting, i thought peak torque happened at a lower RPM...

 

The lower the torque comes in the better you get off the line..
Torque is what pulls you off the line.. Its not always about Peak HP.. Without Torque Hp is nothing.. I was surprised to see the Torque numbers higher than the HP.. Thats a FTW to me..

Making more HP and less torque is a not our goal.. Im very happy with this manifold..
Especially on a NA car with minimal Bolt ons... It made a huge difference in the pick up off the start.. I think most people will agree with me that low end and mid range power is more useable than PEAK POWER and HIGH RPM torque.. I dont drive at 6000+ rpm everyday... I hope you dont.. LOL

 

did you do a dyno with just the weaponR intake, then with the intake mani and intake?

seem like the gains may be from the intake...........

seems like a repeat of the 27hp weaponR header gains..........

 

thats what i was referring to... i thought that the max torque happened at 4k (according to factory specs), the dyno chart shows otherwise...

i know its not all about high end torque (it only gets you going, HP keeps you moving). i would love to run this on my car once my kit is done.

 

I swear... READ DOOD....
WE put on the intake beacause the ARC intake was the bottle neck.. It didnt allow enough flow to the intake manifold.. So we switched out the intake.. The manifold wanted to breather but the intake didnt allow it to.. I STATED that up on the post..

And as far as the 27HP gain on the headers.. If people would read more instead of looking at the numbers and assuming.. That was with the Intake & Headers & Exhaust compared to STOCK...

WE never claimed 27HP on the header.. Here's a link to our website..
On the old MMW website we CLEARLY stated.. it was with I/H/E...

Yes it's Very interesting how the torque changed from the OLDER design to our newer design.. Longer runners and different plenum design with larger velocity stacks..

 

the header HP claim is neither here nor there, and i did read, and you did not dyno the tc with the intake alone, then with the intake and the manifold correct?

im not gonna bash you guys, i was just making an observation, its safe to say that the intake made power, and not just the mani.

you need to do a true no BS comparison, with mani and without, all other factors unchanged.......

 

chico, all that is really irrevelant though. Look at the graph again...the thin line represents the car with the stock manifold, ARC intake, header and exhaust...the thick line represents the same setup but with a different intake and the WR manifold...the HP increase is only 6hp but the torque is nearly 12lb/ft increased. The change in intake is not gonna do that as the only real difference is a slight difference in air being pushed...not gonna change the numbers alone in just that...
i'm not jumpin on you either chico, just tryin to explain a little better..
this graph does show the difference/baseline...thin line vs. thick

 

trust me, i know what the graphs are showing, however what they don't show it EXACTLY how much HP and TQ the intake manifold ALONE added.

this is a moot point anyways since no one else seems to care, oh well......

carry on........

 

pic of it installed?

 

I understand your point, but just changing the manifold won't get you much power. He just stated that the arc induction box, which is already aftermarket and "better" than stock was a bottle neck and didn't allow proper gains to be shown on the manifold. Its like getting a turboback exhaust and leaving the stock muffler, the gains will not be right. The true power with this manifold will only be seem with all the other supporting mods, thats were the real power is. If your getting a manifold chances are you've already changed all the other things that go with a mod like this. So just seeing the intake manifold tested "by itself" wouldn't be a fair comparison.

 

well put.

 

I mite look like a nitpicker but..

What they should have done is dyno'd the car like this:
1st test: STOCK MANIFOLD + WR SECRET WEAPON INTAKE + PRECISION EXHAUST

2nd test: WR MANIFOLD + WR SECRET WEAPON INTAKE + PRECISION EXHAUST

This way, everything remains constant throguh each of the tests except for the manifold. Doing this allows us to see the exact gains of the manifold.

 

well when you guys want to test on a FI car let me know... should have the fic and meth injection in here pretty soon hopefully just need the fic harness...

 

Numbers look good, im glad some1 chose to help Weapon-r do a test run.

As far as professional presentation, Leo seems to get easily aggrivated lol. Ive never had a salesman or any professional employee address anyone with I swear and dude.

Anyway not hear to start an argument, Bump for weapon-r I too have some of their products. Good stuff.
