I will have some pictures of the Exhaust a sound clip and a dyno graph for all to see next week. I have not even seen the exhaust yet, but its on the way here now.

as far as the Vibrant website its at www.vibrantperformance.com great quality exhaust products. we have been selling there WRX/STi exhaust and header for a few years now. Here is the link to there other exhausts we carry http://www.gscmotorsports.com/categories/?id=3641 you can see the quality in the other exhausts.

As far as cost its obviously going to be more than just an axel back but should be in the $600 range maybe a little more but we will see. I know the tC exhaust is very similar to the mazda 3 exhaust on the GSC site.

I would be more interested in seeing an average of three runs with each intake. With the run, switch, run switch method you are not completely cooling down, and you are only taking one data point for each, which completely neglects variation. It isnt a bad test, dont get me wrong, but I would like to see more statistically sound data before basing the type of intake I use off of it, mainly because of the small differences between each. Just my .02 though.

 

The SR is drawing heated air from inside the engine compartment, which is less oxygen dense... thus, less fuel can be burned at a time (same reason you run a FMIC with a FI setup). So basically they are WORSE than stock in that area since the stock airbox draws from the fender well. They are better than stock in the sense that they "should" be more free flowing.

 

well we did let the car cool. it takes at least 10-15 minutes to change the intakes. and as far as letting it cool totally inbetween runs then it wouldn't be a true real world test. sense we did test all the intakes the same way giving each intake the same cooling method should net close to the same margins if we let each run cool back to ambiant temp.

The main reason for doing 3 runs was to adapt the ecu or mass air before the final pull.

 

I would still like to see this
Thanks!

 

thanks for the numbers. this kinda sucks because i just baught a k&n drop in filter....

maybe i can return it.

 

Thing is, while there is no difference between stock and K&N by just dropping in the filter, the AF ratio is a bit better.

I think you'd actually see a difference on a modded airbox setup. Its the stock intake plumbing below the filter that's terrible.

 

Sorry it took so long but here is the Stock VS K&N Drop In Filter



Also wanted to let everyone know that Weapon R is sending us one of there intakes for testing. we will compair it to the Injen CAI that is on the car.

 

this ought to be interesting injen or weapon errrr monster R works . thanks for doing this guys....it is great to see actual data than just hear say and butt dyno's. no test is actually going to be 'perfect' or satisfy everybody, but thanks for doing your best.

 

Yea im with Nemesis...

I have a question you said you let the car cool down for 15 minutes... what was the first intake you tested that day?

 

I used to have the vibrant axle back on my 98 Neon RT. I really liked the sound. Was nice and deep, not even a hint of rasp. I'm very interested in the vibrant kit for the tC. I wanna hear it first tho!

 

Thanks for the dyno. I really thought the stock filter was more restrictive than that, but at least it never needs replacing..

 

First tested was the K&N CAI the Stock, then K&N drop in, Injen CAI, Injen Short, and F5.

Weapon R and maybe umajitiawanatouchthehinny might be sending in there intake. Just got an email from them. All i got to say is sure would have been nice to have them to include on the first round.

I'll try and post the info on Sunday we will try and do it then.


As far as the vibrant goes we will do a sound clip and give our opinion of the sound. and trust me when we say something sounds like crap we will tell you.

 

Keep up the good work...thanks a million!!!!

PS.
You should ask Draxas.com if you can test his Exhaust........
I have the Injen CAI and the Draxas full exhaust and the thing pulls beauitfully.....i work love to see the numbers....it is also a 2.5 with high flow cat straight through with medral bents!!!! I love the sound!!! Just a thought...

 

Intake leaves today. Subscribing for results.

 

can't wait to see the results. these threads are great!

 

It'd be great to compare the CreativeCompacts header-back exhaust with the Vibrant one, when you get around to that....

 

with the k&n drop in filter, would it have been better if the ecu was reset? would i get better gains with this filter is i already have a creative compacts catback?

 

We received the Weapon R intake today and we are waiting on the Umnitza intake. I think the Umnitza was shipped out yesterday, hopefully we will see it before the end of the week.

we will test both of these and post the results for you as soon as we can.

 

Great thread guys!
I'm only chiming in so I can track it.
