His statement about the bet is correct - unless you Track your car.
It's impossible to get the max out of your HP with street only driving.

That is subjective at best and inaccurate at worst.

It is neither. Sorry that you don't get it.

OK, then we’ll keep it your secret.

I reluctantly voted to leave it on this one.

As many others have said it is already a great car with plenty of power and a very well rounded package.

New stock performance cars these days are so well rounded that when you start to modify them no matter how high dollar the build they just tend to loose some of their overall livability and do not operate quite as smoothly and effortlessly as they were engineered to do.

No point in paying money to void the warrant on such a great package anyways.

I’m all for modifying ones a few years old though. Currently I have just a basic 530i for a daily but a 400hp Nissan Silvia as a toy just to satisfy both sides of the argument.

You won't be able to get that power to the ground. I had F10 M5 with massive power and you couldn't get any of the potential power to the ground through the first 3 gears. Just all wheel spin since it is RWD.

Unless you're on a rolling start, even then my car would go sideways under wide open throttle.

If you’re going to do it, go all in!
Is there any downside to altering the intake and exhaust?
Alternatively just pick up a V12 F of choice.
Maybe less HP, but more roar.

Not sure this is the best advice but coming from a guy who use to have an 800 plus hp Gtr , more is always better

Yup, CONTROLLABLE power, aka driveability.

What tune / mods, and gas mix were you using in the M5. Some tunes are a bit, ummm, reaching crazy agressive terratory.

My favorite part about this thread is that folks who have tuned different auto brands are all engaged. Most tune discussions are so brand-centric

Brrrp, brrrrrp, brrrrrp!!!!!

Stage 2, it is significant but there's no downsides. Pretty simple upgrade and cheap.

I used to be a professional Porsche tech and built many race cars and hundreds of mods/engines for stock bodies. I could build something that would destroy the track, but the longevity was 1/4 of what stock was if not less. What you are doing is simple and won't hurt the car at all in the long run (unless you the driver just run it ragged).

....he ain’t gonna do it.

Dinan gives you a warranty. You have a new motor and I think your car is out of warranty so it’s a win win more hp+ warranty on motor what’s not to like? Or just get the M8 and juice that up!

Larry's gone silent. Hopefully he's not on the side of the road looking at rods, bearings and valves from the outside that should be on the inside...

Larry’s golf bag has $20k in change mixed with golf tees and Advil. This doesn’t concern him.

Sorry for the delay, some great comments and good information to consider here.

My new out of the crate engine from BMW has 3,500 miles on it. The warranty has just run out and BMW did not provide any for the new engine.

I have been experimenting with higher octane fuel. I'm mixing 100 octane with the 91 premium octane we get here in California. I estimate my mix is 95-97 octane. I notice and feel more power and the engine loves it! I have always had trouble transferring the power of this car to the tires. I'm running four new P-Zero's 295/30ZR20 (101Y) and the back tires simply do not hook up off the line, when I hit second gear the car chirps and kick to back-end to the right a little.

So... I'm really wondering if I just run my mix and leave it alone? However, I am planning on meeting with the Professionals at Dinan in the next few weeks to learn more so I can make a better informed decision. I already have the Competition Package and all this might just be unnecessary since I don't track the car. We will see!

Personally, dump those Pirelli for PS4S. Have found the Mich offer higher grip, more predictable at the mechanical grip edge, and more forgiving on a bumpy tarmac. Seriously, you'll notice better all around performance. jmho

That high octane all the time is no good. Ruin your plugs and turn them orange

Really? What makes you say this? Even if I'm using it as an additive not at full strength?

I'll check the out. Thanks!

No. Plenty from factory you already aren't going to ever use on the street. I have never been a fan of messing with oem boost/piggyback systems to increase HP in Fi cars. Manufacturer built it to that spec for a reason with the factory warranty in mind. Keep it how it is.

The NOS octane booster has MMT in it Well known fact that it turns the O2 sensors and plugs orange. If you use booster with xylene in it you will be ok if used in small amounts.
I had an F 13 m6 and was advised against this. I now have an f90 with awd. You might want to consider upgrading your ride. I find 617hp plenty.

[Chewbacca]

Don’t worry. It’ll be fine.
