Injen installed, open/closed hood dynoed
 

Added injen intake system today. Did a number of pulls on a dynojet

Stock base pull 145.2whp 129.1tq

Comparison between stock and best pull on injen intake

Max gain recorded was 20whp 3tq

Pulls were done on the same day, same hour on 4th gear

Do we have to reset the ECU to get the after effects ? and if so how do we reset the ECU ?

Thanks :D

I just unplugged the battery while installing the intake, just like what I read on this forum. I cud be wrong tho ;)

No you are right...just need a 10mm wrench and pull off the black wire(negative) leave it off for about 10-20mins and then put it back on. Nice gains, with this car i believe in resetting the ecu with any mod that affects afr and things of that sort(even if it doesnt do anything i will still reset). Just wondering whats up with those weird dips in the graphs, regardless nice gains with the injen

I read this as better top end power but the low rpm power dip has gotten worse with a loss of about 10HP. Am i reading this right???

The rpm sensor on the dyno kept moving... That's why it diss connected on the graph, sorry for that:thumbdown:

That's right sir, but my butt dyno didn't feel it on public roads :iono:

I had mine installed at a dealer so not sure if they reset the ECU or not ... if they didn't ... can I still do that now ?

ECU shud adapt eventually

Nice gains! Seems like it lost a little bit of power/tq in the lower rpm range though. I wonder if the ECU will compensate down the line and negate any gains?

The more i read about the Injen intake, the more i see impressive results.

How is the drive-ability with it? is idle alright, is it rough?

Seems like a really low baseline pull.... hmmm

This is encouraging me to grab an Injen and do some comparisons of my own.

I'm really intrigued at how low your car dynoed stock. My stock pull with ONLY an SRT HB exhaust was 174whp... but I also ran a full unit leaner too (like on your injen run). Take away the exhaust, which is advertised at 10whp and that puts me at 164whp stock... which is what your car ran with Injen.
@Bahraini86, any chance you could email your drf files so I could do a direct overlay in WinPEP?

Wow 10HP??? Could that be real? I mean when do you ever see 10HP from an intake. Especially, it's not even a CAI. Just wondering here...

there's something wrong with your 145whp initial pull to me..

Idle so far is good and drivability ain't effected

I was also shocked with the base run, guess its the crappy 91 fuel

Well if you look at other Injen dyno results, the gains are pretty consistent.. so yes it is real.

which dyno was used, just with that you will have your answer. Or maybe the value wasn't the right one I.E drivetrain loss for a AWD instead of RWD.

:thanks:

Dynojet

was the ECU reset before the baseline dyno too? or just before the injen dyno?

I counted 20...



Indeed, doesn't look quite right.

Out of curiosity...was the snorkel in the bumper removed for any of these tests? My guess is it was removed for all of them including stock if anything.

injen make some nice stuff. they have R&D to back it. they make the best diesel air intake on the market.

ECU was not reset before base run, wanted to know how much it was pumping during day to day driving

Car was totally stock during base run, including snorkel

I assume this was a 6MT? Also, what was the heat / ambient temp like? You end result was similar to my findings but your initial baseline was 20WHP lower than mine.

Also, your runs are in Speed and not Engine Speed (RPM) so maybe you can have those guys send you JPGs of your runs with that selected instead.

So you're saying the different roller dynos will read that differently (outside dynopack?)

Agreed, but it does show trending information to my runs, which was leaner than stock...

Thanks!

I have always work with a Dynapack and can adjust the drivetrain lost.

But i remember one of our guy having a mustang dyno and had to readjust because the number didn't match up.

And didn't know it was a roller before somebody answered the question :p

Be nice to see where it's at after 100 miles or so...

The RPM sensor kept on moving (u can see curve drop extremely in some areas). Runs we're from 3000rpm until redline

Temp was 31 Celsius, hot day indeed

And yes, mine is a 6MT

Sick nice ass gain. lol

Guess we just needa tweak the low end power with tuning or have the header fill in the low-mid range power

Here's a vid of the pull

I did a very rough "eyeball" overlay of our two intake runs in excel. Bahrain is going to send me the drf file when he has a chance to go grab it so I can get a more exact comparison.

The only difference in mods between our cars in these runs is mine has an SRT HB exhaust... other than that it's AFE vs Injen.

The curves look very similar and the 8-10 whp gap I attribute to the exhaust difference.

I'm still going to try and get my hands on an Injen for my own dyno comparison, but from the looks of it... it makes probably around the same power as the AFE. In the case of BAH's car, it fixed his AF so that the car puts out more normal numbers. 145 whp is way too low for a stock car.

Also note this is his best open hood Injen run.

go cowboys

Hi. I may have missed it elsewhere but do you have a dyno with your Visconti tune with and without the Injen? This would be really useful as I may go that route if the gains are worthwhile. I have already signed up for the Vis tune and E85 but have no car to put it on yet! Thanks.

this whole thread is no good to me .. that baseline dyno is just too weird. 145 is the lowest I have ever seen.

Any base dyno runs with 18" wheels?

Any dyno tunes with aluminum shift knobs?

Seems u haven't heard of rotational mass. How come a light pulley put some power on the dyno!?

watching.

What kind of gas do you have there? 145 is very low on the stock dyno it's possible the ECU had encountered some detonation along the way and the advance was down. I bet if you had reset the ECU before the stock run it would have been near 160 by itself.

FWIW, I did two pulls on a dyno with my car relatively stock. 152whp average. Pulled battery for 2 minutes, did 2 pulls, average 161whp. So unfortunately the battery pull on a 145whp baselin could have seen 15whp more just on that if its like my car and 5whp for the intake.
