The only way to get this much power out of an Injen Intake is if you combine it with an HKS SSQV and remain untuned.

 

hehe

 

I totally agree, that's what I did. I was torn between a china made turbo on ebay and a SSQV, but I decided the SSQV was the better choice.

 

I don't think there is any way on earth you'd get 22whp with that intake without a tune either. Heck.... i think you'd get 22whp with ONLY a tune.

 

ok, ok. So is there any proof/dyno numbers/timeslips, that an intake with cone filter like the Injen will yield better results (with a tune) versus the stock intake system (with a tune) given the same or similar A/F ratio?

I'm not skeptical, but just curious?

 

I highly doubt anyone has put this much into an intake by itself. I would be pretty confident in the Injen dyno sheets.

 

You might ask over in the Vishnu forum, or send them a PM. I think they've done some testing like this, but I'm not sure.

 

hahaahh funny you should menchine that i have 1,300 in my intake manifold LOL, mangus, though similar i would not know about the differences inbetween the two BUT... mine is equipped with piranaha injectors, 5 solenoids for a setup where i can adjust everything independently, :P

 

Here are two dyno charts of my car back when I just had a UTEC, TBE, cams, MBC, and the Injen kit. I later learned my AFRs were very rich (low to mid 10s) which is why my power is low for those mods. Injen's sniffer wideband was off (reading low), and my tuner's had been high.

The graphs in red are the Injen graphs (Intake and UICP kit). These were done in front of me on the Injen dyno on a very hot (95-100 deg) day. I watched them dyno with my stock intake and UICP, then quickly swap in the Injen kit (~20-30 mins) and dyno again. 3 runs on each setup.

The kit apparently caused a significant gain across the powerband, but the peak numbers are very similar. There was another graph of a 3rd run that I can't find which showed a greater peak gain. On one there appears to be a ~40 WHP gain at ~4-5000 rpm.

 

Can you post the dyno sheet?

 

 

The thing is that if you are AFR is too rich, then the intake will give more power, but after a tune you should get more powe.
Now when you guys say 22 hp after a tune , How we know it was not the tune that gave the power?

 

Bahh, screw the intake! Just take that sucker off and use an hks ssqv. MAD POWA!

 

Greetings All,

One thing to remember about open intakes on the evo is that you can not compare dyno numbers to real world gains. The main reason is that you are on the dyno with the hood up and fans directed at the engine. There is one rule with open intakes. The second the air intake breathes air that is warmer than ambient, you will lose power, period. This has been tested time and time again. Now for drag racing, different issue. Driving on a road course, different issue. In daily driving, stop and go traffic, you underhood temperatures will reach upwards of 160 degrees. Doesn't take rocket science to realize what that would do to performance.

For what it is worth, that is my two cents.

Cheers,

Same old song and dance. If everyone is so worried about underhood temps, then why don't you just make your own cold air? It would be too easy, and I'm sure that by the time the air reached the MAF it would be smoothed out enough for it to continue reading correctly. Or... (gasp) Keep the stocker. I for one like a little "bling" so I don't care. But it would be interesting to actually see tuned stock vs. tuned not.

By the way, since when do you care about your power output in stop-and-go traffic? I'm lost.
