Because we found out that the A/F was OFF, so i was way too annoyed to get alex to do a Final dyno chart. If you want the right axis, there's another pic that i did that has the right axis.

Thanks for all the comments. I love my intake. It should gain power once i tune. So, im okay with that!

Looks like this is off the axis too then



Not trying to start a conspiracy here, just noticed this myself and wondered why they do this to all their dynos. This was on the same day too no?

They always have the axis correct. Perhaps they got forgot this time.

Just out of interest.. How much did you spend in total? Like over $3000 for all that?
I bought the Technocraft stuff and its nice, but only three pieces. It should make horsepower so there is a mistake. It takes 30 minutes to remove, why don't you remove it and re do the dyno and then re install it while it cools down for 30 minutes?

In any event, for an extra 9k you could have a supercharger! What you have done is a little bit of a waste

Why does your torque curve look all funky with the tecnocraft stuff?

The car doesn't seem to be running right. You are barely making more horsepower than an E46 at the crank.

Maybe it's time to take all the mods off and have BMW check it out. An ECU tune might fix it, but it also might be something like fuel pressure or high leak down numbers from the bottom end (rings) or top end (valves) if the car is that weak.

Well, I would do that, with AFR, but there is still value in doing a dyno after the engine management has adapted. Fuel trims will be adjusted over time, so you could potentially show short term gains that dissapear as the ecu attempts to hit desired values. The opposite could also be true.

both your dyno before and after should line up where tq crosses over with the HP at 5252 rpm range. More importantly both those graphs should at least intersect at the same rpm range. Look at almost any dyno graph and you will see that they all cross over at 5252.

Ed, I think I just missed you on Friday. I was at Gintani around 1pm, Alex said you lost some power, sucks to hear that. On the bright side, the full intake looks AMAZING and hopefully a tune can resolve this.

The Gintani dyno is a really low reading dyno. I'm sure he'd be close to 340whp on a dynojet. Don't think there's anything wrong with his car other than the intake cost him 5whp.

imo, you need to start getting some ecu tuning done to fine tune your A/F's. I really think once you do that your car will perform to the best of its ability with the given mods. If you plan on doing any other performance mods like a pulley or xpipes etc (assuming you don't have them already), do those mods before the tune...no point in paying to get tuned twice.

anyways, good luck..seriously. I know what it feels like to dump money and getting less than desired results.
I think its a simple equation....your letting more air in and freeing up the flow. Stock ecu can only correct timing and fuel to a degree. Getting a flash tune will help tremendously.

good luck and keep us posted

Gintani has been in business long enough and prides themselves on proving power that their products make. I don't understand why they scale the numbers differently for their after mod runs.

The only time I have ever seen the curves not crossing @ 5252 is due to the scale being different on for HP and TQ. I can't explain is the one below and Eagleeye's don't cross at the same RPM on the different runs. Since both curves are in the same scale they should cross at the same rpm point and on those graph they don't. Is there something in the Dyno dynamics Software that does this? I have never seen this from any other dyno manufacturer.

True. However, his baseline was 310, which is pretty low even given the other dynos I've seen from Gintani. The intake loses power and/or his car is running very weak.

Let me first point out that, yes, this dyno maybe skewed because i did NOT dyno a stock dyno and an after dyno ON THE SAME DAY! yes i know it is NOT that accurate but imo, its good enough for me.

So, the bad. I LOST 5whp. Yes sir. LOST. SUCKS!!!! I had 310whp before. Now its dynoing about 305whp

Stock Dyno results:



Stock dyno thread: http://www.m3post.com/forums/showthread.php?t=337047

After Dyno results:



Videos:




Now the GOOD! Gintani was pretty puzzled by this as well so, Alex decided to pull out the A/F ratio while he was dyno'ing and his gut was right. YEAHHH for ALEX!! Stock A/F is 14.1 ish and now my A/F is around 12 ish:




Sooo, its fixable! PHEW!!! So, now the question is how much will this ENVY gain with a TUNE?!?! I dont think i can answer that question cause ill probably be getting a tune after my exhaust. i hope someone steps up and does it tho. Im guessing tecnocraft will

So yea, its not what i expected but meh! BUT!!! The WHOLE system looks SICK!!!!! I got the headlight covers and the left passenger cover as well.





Again, Thanks to ERIC@PYSPEED and KING@TECNOCRAFT for getting me these piece so quickly so i could have them this past weekend for WEKFEST!

Ed Lin
you forgot to leave me those covers over the headlights dude!

The torque and hp curves intersect at 5252 rpm only when the torque is measured in ft-lbs and the power in horsepower.

I would be willing to bet that there is no power loss. I would say it is due to the fact that the two runs (pre and post intake install) were done on different days. So, what does the ole butt dyno tell you? Does it feel faster?

So he paid more than 2k for the system and end up not gaining one thing at all. The claims of the tecnocraft system with the intake alone was suppose to be +18 but that is with an aftermarket filter and not OEM filter. Now everything is enlarged to receive more air but nothing charges on the car but a loss of hp. How doesn't more air get in the car when the two places that receives air isn't increased at all? This isn't like a supercharger where it is forcing more air into the system.

Butt dyno doesn't do anything, but give you a placebo effect where the amount of money spent you feel it goes faster but it doesn't.

The system looks nice, but there is no function to it. The system rubs on the hood in various places and has gaps around the charge pipe (so you get unfiltered air into the motor), on top of that, there is discussions about why did tecnocraft drop the accordian looking piece and why other major players (Dinan / Gruppe M) that have been modifying bmws for a while kept it just like OEM and didn't change it.
