Default Dyno #'s for '02 WRX

I went to Agile Auto yesterday for there Dyno Day that turned out to be 3 people in 3 hrs. They have a dynapack, which i hear runs 10-15% less than other dynos. I made 199 hp and 206 tq. if you take in the 10% correction that is 219hp. If i am wrong with the correction please let me know, i dont want to be telling misinformation.

Mods that Matter: Lightened Pullies, TXS UP/DP/Mid Section/FMIC, Blitz Nur Spec Rear, HKS/ZeroSports Intake. This is on a stock turbo without engine management spiking to 16 psi then leveling to 14.

That is the plan whenever i can get some $$$. i know that i am doing the modding a little out of order.

would injectors fix the AF problem without EM or would EM alone fix the AF problem?

You don't need an in injector upgrade for the stock turbo.
I am running a tuned map of the cobb stage2 and my IDC probably peaks about 90-92%. I am running about 11.2:1 A/F and my boost spikes to around 17.5psi.
What some people don't realize is that, the IDC reaches it's peak at redline typically where it's richest, NOT where your peak boost is on the stock turbo. I could easily turn the stock turbo up to 20psi and still have headroom. My IDC at my peak boost level is (off the top of my head) around 87%.

Is the FMIC throwing my AF out of wack? Or is it the boost controller? The controller that i have is the ABC from a UTEC. Would a Fuel pump fix the AF. If i was to go back to a TMIC but stay with the ABC, does anyone think that would help with the AF.

Running a "boost controller" with no means to adjust your fueling is throwing your AF out of whack. Are you getting any knock?

Just adding a boost controller is fine on an 02-03... your AFR's are probably ok. Problem is you threw another factor into the equation... the front mount is DEFINITELY skewing your AFR's.

And just because you don't hear or feel any ahrd knock, doesn't mean it's not happening.

you spent tons of money on those parts to gain ~30 whp and most of that probably comes from the $20 boost controller. Please do yourself a favor. Spend under $1k for EM and a tune and you'll probably double that hp gain.

I totally agree. This is stupid. Why waist money and risk destroying your engine. If you don't know what knock is, you should probably do some research...a lot of it. Why put on mods on an expensive car when you don't know anything about what it does!?! Did you talk to Hill at AA? He's a very knowledgeable guy.

Sell the FMIC and boost controller and buy an AP and you would probably end up with some extra cash not to mention your car will have more power and SAFER power. And definatley get a protune from Hill if you can.

No i did not talk to Hill about the AF. No on e there seemed to awfully concerned about it. The only thing they said was that the car is idling a little rough, and to change my spark plugs.

I have thought about doing this after going to the dyno.

You would get very similar numbers on a tuned stock WRX and not have to worry about blowing it up. Even the OTS Cobb Stg1 map will get you around that area, a 590ish dollar part that Agile can use now and in the future for making your car operate properly.

As everyone else has mentioned get some EM and your going to need it professionally tuned for your mods. Even still it might be tough to take advantage of alot of your mods with a stock turbo and stock fueling.

Knocking is pre-detonation. Combustion accures when its not supposed too due to air/fueling being out of whack. I've never heard it on a WRX but most be say it sounds like a BB in a tin can being shaken around. A couple serious knocking events will take its toll on your engine, if it doesnt take it out completely.

i would just put ur stock TMIC and stock intake back on until u get some type of EM.
dont waste ur money on an intake since stocker works very well, especially for the minor mods u have. i think the FMIC and intake are making ur a/f whack.

just keep ur FMIC on the side until u get the bigger turbo, injectors and fuel pump.

then put it all back on, get ur EM tuned and u wll be good to go. then save up for a tranny.
