" Forgot to highlight, this is just an opinion based on what we've lived through before...take it FWIW "

" I call bs on this to be honest. I had one of the pretty well known euro tuners (who makes downpipes) claim that without a flex section in the downpipes the heads would 100% crack on the N54 how many are running downpipes with flex sections in them again? "

" Yeah, look at it this way, road courses key is to finish the race, 1/4 mile you just need to make it down the track lots of tune related things can be optimized for power at the 1/4 mile when not worrying about heat soak in top speed runs and such...OTS will be a good all around tune but it will never give you the ultimate edge in any sort of racing. You can get fairly close with OTS to a good all around setup though.

Don't know anything about any of these S65 kits other than what's being presented online and some things I've seen locally. I wouldn't have anything worth sharing there right now. From what I've seen so far they all perform well and some look to be of higher quality overall construction/build wise than others. If/when we get into tuning S65s we'll be able to share our thoughts better. "

" [QUOTE=evolve;468547]No.. that's knocking. Pulling timing does not create a jagged graph, it just smoothly lowers the graph and maybe add a few subtle waves if the timing is pulled by an equal amount globally on the WOT timing aim map.

Under 5th gear the run is much longer and the DME has a much longer time to achieve the targets and the sampling rate is higher on the dyno due to the extended time given.

Now, some of you have spoken about knock being possible at all. It is ONLY possibly if the targets are too high to start with. While the DME can retard knock it cannot do it fast enough on a boosted application. Knock tends to have very much a domino effect. Once it starts it keeps going. So you would have to pull massive timing quickly to stop the knock.

These are the very basic fundamentals of engine tuning.

Supercharged cars needs to be running as less timing as possible and that target should be set under the worst case scenarios where temperatures are high, octane is low, boost is high etc etc. Good tuning is always done for the worst conditions, not the best. Then you let the DME add to all of that with it's multiple compensation maps.
Setting high ignition targets and letting the knock detection system control everything is not very clever. "

" Good stuff actually! I've done the same last year on my car. All the charge piping is wrapped from the turbos to the intake manifold. Certainly can't hurt "

" We recently received a call from an east coast shop owner who does some of the cleanest work I have ever seen. He runs a full race shop and has a 2008 135i with only 5000 miles on it. All 5000 miles are track miles as the car has never been registered as a car to run on the street. He is running RB turbos and full supporting bolt ons and tracks the car on 93 octane. We have decided to join him and support his tuning needs for the upcoming track seasons. After hitting the dyno today we have dialed the car in a bit more and focused on a tune for long / high heat and intense track sessions. 3+ hours on a road course tends to take its toll on a car and without the proper tuning and cooling it could cause problems. Between the tune we put together and the custom built parts on the car - this is going to be a very fun partnership.

Without the specific components, additional cooling modifications, and custom built race parts that he fabricated in his shop - this car would not run as well as it does. The car put out impressive numbers on the dyno today. It made about 443whp and 432wtq and never touched over 18.09 psi (set to hit and hold about 17.5psi but flirted with 18.09 for about 150rpms lol). We have a few more revisions to get everything dialed in perfectly. This was a third gear pull on the dyno as we ran out of time to start doing some 4th gear tuning. We will probably keep the car well under 18psi even at high load.

On to the impressive pictures!

" Hey guys, for anyone interested, F10 M5 parts are slowly starting to trickle in. Our friends at AMS Performance have just recently released really great looking downpipes for this beastly motor. Check it out..

" Thought I'd start a thread to share out some customer vids we got over the last while. Some of them have descriptions some of them don't but they're always fun to watch and show some really nice real world results outside the dyno rollers where at the end of the day it really matters most...

Cheers!
