Out of interest, I looked at your logs. I see what my budy did....hehehe. Nice to see the implementation though. Based on your wgdc and IAT you were in negative DA weather. So was your numbers SAE, or STD ?

Here is some reference and comparison, but it was triple digit temps in 1700 DA. Didn't get a chance this year to tackle the negative DA weather.



Here is my 100-200 times in 83f after midnight couple days before the dyno






Here is the dyno log

Its 30 degrees here lol. It was std. But even on sae i think it was 500whp.
Is that an appfor 100 to 200. I have the winpep file aswell if your interested.

What do you think of the logs?

I credit good numbers to good weather too.

I like what he did with the AFR

Seems he kept things more in "characteristic" to stock but with more power, and kept it simple but effective. I do something significantly different and perhaps more detailed.

How it performs on a dyno vs how it will perform on the streets are two different things, but you will come to know this soon. I am interested though to see what you do at the track, just dont break anything, its not worth it. It will cost more than a vbox if you did break something. Keep that in mind.

BTW my dyno and lapse time was done with a CM 850 twin disk, beautiful clutch but I couldn't bare it anymore. Was either bad install or bad kit.

What didn't you like about the clutch. That's what i have.
Last time at the track snapped an axle hence the mfactory ones.

It was noisy as hell.....lol, I mean way more noise than what I have experienced with their competitor twin disk that most N54 owners get.

Like I said though, I dont know if it was an install error or bad kit. Im sending my kit back to CM for them to inspect it. My feeling is that it was a bad install due to the aftermath of the install work that had me in doubt. So damn happy it didnt affect my gearbox though.

Just keep an eye out for when you engaged the clutch and start getting a grunt or roaring sound as though you have a bad throwout bearing. The first instance you start to experience it you need to address the issue. The grunt or roaring sound will eventually follow when you start to shift fast.

When the tranny was pulled the throwout bearing , pilot bearing needed replacing, plus when they went to pull the flywheel the snout just fell off, and there was no effort at all to pull the flywheel. So needed a new flywheel also.

Ive had about 7k no problems. It is noisy tho i have solid bushings for trans and diff and all you hear is drivetrain. I don't mind it tho.

I heard 12-13% for manuals, 15% for auto's, and low 20's for AWD models. Obliviously there can be a lot of variables though.

Theres many variables to all of this. Drive train and so on. Even for power. Motor wear, oil wear, turbo wear all play factors in power made. Every car is very different.

But who knows, maybe you have a freak car! I have seen with my own eyes a local 135i on OEM turbo make 495whp and 612tq on the same dyno as mine. But his power fell like a rock after 4800rpm.
I'm sorry. You are correct. There's no way this car is actually making 500 at the wheels. The dyno might have read that but it will be wrong. On 19 psi. Not a chance.

I'd also be amazed if a car without meth, throttle body injection or port injection had enough fuel to reach 500.

As Terry said you'd be looking to trap around 130. Never going to happen.

I'm sure the car feels fast but in reality I'd think more in the 420 to 450 range at best.

I did a test hit on vargas GCs. 20 psi at 6500 rpm came out at a predicted 508 whp. I'm running port meth injection. Down *****. Inlets, outlets etc.

A quarter mile trap speed will confirm the rough power level. Or the 100-200 pull.

I haven't seen his log... But maybe boost is scaled wrong and its making more than 19psi, etc. 500whp is certainly possible with inlets on stock turbos. We've done it before. But it takes more like 22psi peak and lots of timing.

That's why it's best to capture boost on an external boost gauge to put a hush to the doubters

420 lol....you predicted 508 so that's like imaginary. The dyno confirms the level thats what's it job is....your just silly.

Lol idc about the haters. I honestly don't post much here because of that. I only did it as a referance for other users with stock turbos to see what you can do.

Make 501 you need at least 22+of psi , methanol and a very aggressive tune
like Trebilia ---the best.

No I didn't predict it mate. It's a calculated estimate based on weight and acceleration data. Just like a dyno does. Recorded off the cars dme via the jb4. All Dynos have to predict and make corrections based on algorithms.

Sorry to break your dream with a reality check. Better to be realistic, no?

By the way, I haven't seen your log because I don't know where this datazap file is, but if I assumed you were running on an AFR of 12.5:1, then you'd be roughly asking the Turbos to flow 314 cubic feet of air per minute. That translates into 0.148 cubic metres of air per second and puts you somewhere along the red line for the stock turbo efficiency map.

I have made some assumptions and not thoroughly checked this but it looks plausible.
