i also have the injen intake, i prefer the weapon r over it.

it appears that the only solution would be to get something to control the A/F ratio.

 

Dam, i wish i didnt see this.... im putting my WRI in today....

 

Well, I finally found a photo database to use. The link below goes to the dyno that Ray at Weapon-R/MMW sent me back on 10/24. It shows the power curve of the newly designed intake. Too much loss at 2300 RPM's for my liking...When the pictue loads click below it for full size, otherwise the blue line on the dyno chart is dark and difficult to see.

I just installed my intake yesterday, and just from driving it for 2 days, i can definitely say that there is a drop in torque in the 1700-2900 RPM range, especially in 2nd gear. But I have to agree with senseiturtle>>

 

i guess alot of us are figuring out what the dyno details are eh??? lol

if you check K&N and WR's dynoes, they both start to drop on low end torque. though WR leads with a better top end

i havent seen Injens dyno, well dynos from other people and not the company itself... tho the one that Injen officially dyoed should have just a tiny bit of lose on low end...

from the looks of all the dynos, weapon-r loses the most torque..... and i think Injen is the overall good performer... now you guys got me thinking i should get an Injen intake instead, and i bet that nice dyno shows the INJEN CAI (no SR)...

and hydrolocking would suck because of the CAI, i mean it only takes 2 teaspoons of water to take your engine out

 

And now someone must show the gains from a cold air box.

I imagine if a box doesn't replace the MAF mount portion of the pipe than it'll keep that torque while showing similar gains up top.

 

Unless you are driving through 2-5 feet of water, I doubt you will ever see hydrolock on a TC with the Injen CAI. The position of the filter is pretty high from the ground. Not to mention all the engine covers located underneath the front bumper.

 

my butt dyno says that the injen has very little low end loss as a sram. it does not pull as hard as weaponr at higher rpms but it's still kind of nice to have that low end response.
i would imagine that when someone develops a decent a/f controller that the weaponr will be pretty awesome.

 

well...
i have the weapon r with the cold air box
and the dc sports exhaust.
i havnt lost much low end,...
it sounds great too.

 

WOW! and I was going to get the weapon-r... forget thaT!

 

honestly, I believe that this is just an issue with all after market intakes, I dont think there is any other intake out there that will solve the problem. I have the WR Short Intake on my car right now, and I did notice the difference you speak of. I could actually hear the difference now then I had heard before. However I love the look and i do notice a loss in the low rpm's but, I can definitely feel the gain in the higher rpm......so in reality, you win some, and you lose some.

 

I had the WR for a while and it wasn't very noticeable. You have to realize though it adds the tq and hp at the high end like most intakes. Most people buy it to race or have that "race feel" and when you race you take off at least 2500rpms and will never enter the lower end were you'd feel it. If you want your granny top end then keep the stock.

 

Everyone has been experiencing the same problem. I stumbled into the same issue before I even knew about it. I now have a NST SC pulley and a WR SC intake sitting in boxes. I know my ulitmate plan which is worthy and I suggest it you everyone one of you guys. Just get some type of piggyback or any software that can adjust parameters set on the ECU and dyno it. You will get the A/F ratio you want while being able to stab at other adjustments. Trust me, I know it is more money yet you will be so happy after you do all of this. You will be running closer to power ranges that the SC should have come factory with. I am very excited and I will keep you guys posted if you interested.
