M Coupe Turbo videos

[Blown M Coupe]

I finally got around to digitising some video I took a few days ago, so here they are!

The first one is on a private road accelerating from 0-120mph. The second is me having fun with the camera on a tripod. The exhaust sounds so damn cool with the high-flow cat installed, I just had to do a couple of external shots.

Here's a dyno of the car as it performed in these videos. My goal is to improve the 5k-7k range and hit 370whp. A little tuning is still needed.

Oh I almost forgot, this is an Active Autowerke OBD2 turbo stage 2 with no boost controller. If anyone has any thoughts on how to achieve my goals, please let me know! Thanks.

damn, good job with the M

Blown M Coupe, thanks for sharing the videos. It should be very easy to achieve your goals- turn up the boost and get it tuned. If you have the lower compression head gasket installed, our internals can easily handle 14-15psi. Just make sure you have the proper fuel tuning at those pressures. I would contact AA and ask them for advice, they know whats best for the system.

very nice, thanks for posting.

Hey, Nice car... I love the rims... part of the benefit of having an MCoupe, eh? What size tires are you running on those bad boys?

Also, few more questions, if you don't mind... are those magnaflows or stock exhaust? Do you have cats on the car? And finally, how much boost is your Stage 2 running?

Again, nice vids...

Boris - thanks, the rims are Kinesis K19R with 275/35/18 rear, 235/40/18 front. The exhaust is the loud B&B Triflow catback exhaust with a 3" single port high flow cat (not sure what brand). I don't have a boost guage so I'm not certain, but I think we're at 9 or 10lbs boost.

I'll check out the dyno/video forum.

Ahh.. I see... very nice.. I'm jealous of the size tires you're able to squeeze in the rear! Ok, I thought the exhaust sounded louder than usual but didn't know if it was your camera as sometimes they record quite differently than it really sounds (mine is super sensitive, that's why I asked).

You should really have a boost gauge on your car... get one on there so we know what's going on...

Again, sweet ride

Great #'s, have Karl give you 2-4 degree's more timing in the mid to upper end. 25-35rwhp gain can be achieved, good luck. 1 bar of boost with proper tuning = 400+whp with ease.

Hey man, sounds like you are well on your way. If you get that thing tuned properly you should be set. I suggest getting a fuel pressure regulator if you havent already, and something that will tune your air/fuel, you should be able to gain at least 25-30 HP if that is done correctly. You always have the option of raising your boost, but work with your other options first to be safe.

George, do you even know what kind of tuning he's running now? How much timing? Where? Or, even better, how much boost or anything else? How the hell do you predict where to add timing and how much power it will gain? Is this the way you calculate power on your cars?

I wouldn't make recommendations like that without even knowing anything about his setup... let him and Karl work that out... I'm sure Karl knows much better what the car needs.

very nice...

tell me more about the high-flow cat you have installed. your Coupe sounds awesome.

[M3 Kid]

Boris, I'm assuming George is giving that advice under the assumption that it is "out of the box" stage II software, and as we both know, George has extensive experience with AA stage II cars..
