with all this talk of spinning out wheels, i always second guess if my car is running strong

Now my stage 2+FMIC aggresive dyno:



Notice the "red" line pull... I took off the stock air box cover and let it basically run no filter (about what would happen with DCI) and you can see the gains, especially after 5k RPM's it was like 10 TQ and 15 HP. I also still have stock exhaust...

Ran a 12.8 @ 113 last night, seems slow but track was slow. C5 Z06 (automatic tranny) best run was a 12.9 @ 108 and there were 2 of the 5.0 mustangs there with intake/tune/x-pipe type mods both running around 13.2-13.4 @ 110-112. My 60' was 2.0

Enjoy

I went to the track last night too but got rained out before getting a run in

What are your exact mods? And where were you shifting?

Zeph

lol what a ricer! too bad you didn't get a pic of that. most of the guys with fixed roof coupes that try to make them look like z06's at least do the rear wheel vents. to go as far as to add the z06 emblem though...what a poser

AMS FMIC, AR 3" catless DP's with ceramic coating, Synpase charge pipe and BOV kit, MS panel filter (wasn't really dirty either), Cobb AP Stage 2 + FMIC aggressive, 6MT. I shifted around 6k to stay in my torque band. Tried going to about 6500 and ran a 13.1 @ 110.

Yeah need to find the balance of rpm drop between gears to shift at or before 6200 rpm and fall back on or before 4700rpm maximize the powerband... Car should theoretically be trapping higher at that power level wish I could have offered a comparison today as my mods are cobb stage 2+ aggressive, helix fmic, afe sealed intake, plm dp's, helix bov's! It's literally been raining here for 2 straight weeks

If you still got dws, they're simply awesome.

I can't break these loose either no matter how cold it is from a roll. Best kept secret in tires today.

I really think the track had some issues, my friend's new 5.0 mustang has a cold air intake, tune, x-pipe, and 4.10 rear end. He ran a 12.7 a little while back, but best time last night was 13.3. We are going to a different strip within the next couple of weeks to try again...

Still can't really figure out how to chart the results, tried using some line charts in Excel but they aren't working right. Boost gets up to 18.39 psi @ 4138 RPM but @ 6003 RPM it is 11.63 and by 6779 it is 8.96 psi. Wasn't stage 1 holding 13 psi until redline?

The boost reporting for stage 2 past say 5k rpm is incorrect. Someone logged the Cobb stage 2 boost curve using the jb4 logging and it showed 13 psi at redline. You didn't think u were making close to 350 whp on 9 psi boost did you?

[Jeff@TopGearSolutions]

Shifting at redline is not the fastest way down the track on this car. I'd pull 1-2 lengths on most cars shifting at ~6100 then if I brought it to red line.

As themyst said the current stage 2 logs are wrong for boost after 5K.

[Skrba]

Mods:AMS,TBE,MR.5 intake


Stage 1 91octane map 13.5psi
Stage 1 93Octane map 15.2psi
Stage 2+Fmic Drive map 16.5psi(linear is NOT good choice feels way to slow)
Stage 2+FMIC Sport map 17.3psi
Stage 2+Fmic Agressive did not even want to push after seeing 17.3psi on Sport map.

In my opinion after trying all maps Stage 1 93octane map in clear winner!

Lowest boost levels but feels stronger than even Stage 2 Sport map with its more agressive throttle.

15ish Psi off boost with full bolt ons and intake on 94octane gas is more than enough for this car in every way.

Even now i do feel that lowering the car is a must and it would be fair to say that at this point 335i in every aspect is lacking rigidity of M3 chassis.

Zeph,
What mods were done on your first dyno?

[vasillalov]

Tried the Stage2+FMIC Aggressive map last night. There were some random oscillations under part throttle in 3rd and 4rth gears. Those oscillations can be felt on the butt dyno and heard in the exhaust note. I don't think those were throttle closures but I could be wrong. Unfortunately, no log, but I'll try to get one soon.

This must be specific to the Aggressive map because the Sport maps does not have this problem.

It pulls harder on procede but it is also more boost.

I have encountered the same thing. It seems to be common for those running a full turboback exhaust. I have not heard Themyst mention it happening to him.

I am currently running Stage 1 because I don't like Stage 2's linear throttle for my daily driving, and have not had these issues on anything but Stage 2 Aggressive.

Still trying to get the hang of logging so I can see what is happening.

[themyst]

Yep, no oscillations here. I'm running stock exhaust.

[thebigragu99]

What do mean by oscillations??I really don't know how safe these maps are with all this boost.The stock turbos are very tiny, it seems that's there over spinning with these type of boost levels ..why not make the same power with less boost and a bit more *?? There should be a equal balance in the two while making a great map.

Have you ever seen compressor maps from these turbos?

And here you are again

The turbos are fine for this boost level down low. No problem.

Anyways, the oscillations can be felt and heard. The exhaust note does a braap braap braap. It's not a misfire and causes no codes.

It only happens on Stage 2+ Aggressive and only when applying partial throttle with minute changes in throttle angle. I have been paying particular attention to exactly what my foot is doing when it happens and it never occurs when at a steady partial throttle or WOT.

Seems almost like there's a point where the throttle is too sensitive and that's what causes the problem. It's as if you're giving gas then letting off then giving then letting off several times rapidly.

[jb's335]

Would the Cobb AP ever be able to bypass the stock boost control solenoids so we could run upgraded turbos with external wastegates? I still want to run twin turbos however I would like to go bigger than upgraded stockers. I know the JB4 cannot do this, so I was wondering if the AP would have this kind of control over the DME?

I could use a standard EBC to control boost. I am not trying to go over 20psi at the moment, especially with big turbos as the engine probably would not be able to handle it. Also, is more fuel possible if we upgraded the in-tank fuel pump?

Sorry for the 20 questions, and if these have already been asked/answered in this thread. Thanks for the help!

[thebigragu99]

I know what your taking about now ..my old turbo did this when I went s.d Te tune dis a crappy job!

From the dyno graph posted above by the op ,it seems to make the same or less power the a Fbo jb4?? Correct me if I'm wrong ? Thanks

It should be able to but you would need a custom tune. Anything can be done with money. But I would think a standalone is the way to go for full control.

^ Did you just quote yourself?

Yes, should make very similar power to any properly tuned JB4 / Procede V5. Power delivery and tuning may be different, but at the end of the day it's limited by hardware. So all competent tuners should be able to hit approximately the same amount of power.
