I was very pleased with the NOS, I have never had NOS installed in any of my cars ever, but I figured I would give it a shot. So my brother ASR Engineering (Abid) in conjunction with Active Auto put together the NOS kit for the M5. My brother did the install and then Active help create the software to make sure the car ran safely with the NOS. I wil get Omar at Active to post the Dyno sheet.....
So far with my personal experience the M5 seems to love the NOS and according to the Dyno graph it is safe with a 100 shot and the Active ECU tune. From testing on the Dyno you can run the NOS without the Active ECU tune but ASR Engineering doesn't recommend it. He says the Active Tune makes running the NOS very safe and reliable. The tune used on my car currently is good for street use without NOS and also with NOS.
Also I was able to run a buddy of mine with the stock M5 with an X-pipe (MiamiM5) and we ran several times from 60-150 and by 150mph I have a car length on him. Also keep in mind I am running a 20 inch wheels during that test vs. a stock 19 inch wheel (MiamiM5). I have some video but the quality is very poor since we filmed at night.
For those of you that felt the ECU doesn't make a difference now there is proof it does, I will tell you most of the differnce in power is felt from 60mph and up.
Running on the 1/4 mile track both cars had very similar time slips in terms of ET and mph but also keep in mind I was running 20 inch wheels vs. stock 19 inch which will give you better 1/4 mile performance.
I want to thank everyone for the compliments in the previous post, thanks guys.....
I also want to thank FikseGTS for hosting the event last night and posting the video.
For those that want to know FikseGTS ran 12.07 @ 116.33 with every single thing still in the car from the floor mats to the stock Air filter, in fact I noticed someone asked if he still had the air filter in the car and the answer is YES. I tried to convince him to remove the filter and if he did I'm sure he would have broke into the 11's. In any case 12.07 @ 116.33 on a completely stock E55 is AWSOME.
I don't think the NOS is for everyone, but I will confirm that on the M5 with a 100 shot the car is very civilized and holds its composure very well; the power delivery of the NOS kit is very smooth and not abrupt.... Jay.S
