How do all these increased hp and torque modifications affect the 0-60 times and 1/4 mile times along with trap speeds?

If we really see 20PSI of boost in real world driving, then that is one piece of evidence that supports under rating (if we are to believe BMW's claim of a absolute max boost of 18PSI... This might have been misunderstood though and it might also be that 18PSI is max for normal conditions and the DME can use overboost for worse conditions?)
I'm not at liberty to post anything while the units are still in Beta. There is another website that you can go to to check a couple of the logs, but I still don't think you will be finding much there. Patience!

That's yet to be determined, but I will take donations for a VBOX and strip entrance fees and race fuels

Not sure at the moment. Your best bet will be to contact Burger tuning directly.

I'm curious if we will see 600whp on stock turbos. With meth/water injection, intakes, downpipes, catless exhaust etc... Seems like at least a small possibility. Would be insane. I'd have to guess high 10sec passes would be possible with the right tires at that point?

Thanks for the info (even though I am still looking for datalogging of the bone stock car, no JB4 datalogging needed)

Best of luck, impressive gains

I'll see if I can get you something when I get my car back. It's currently getting a proto exhaust put on. More to follow

It's no biggie. It was only if you had it "lying around"

Since we're still datalogging, we'll be getting data from 91 as well as race fuel.

That's great news, Tom. Again, your data and the info you're giving to the community is incredibly helpful and I think I speak on behalf of everyone for helping shed light for all of us.

I know Drew, Josh, I are all stoked to get up there at the end of the month!

It appears that it's vastly easier to throw a car on a dyno than it is to take it to the track.

Someone track this puppy. I mean, c'mon, with DCT it doesn't even require skill anymore. Just press 6 buttons and go!

Let's all remember that it all comes down to traction. A 100whp gain means little if you can only effectively transmit 50whp of that. Let's see how well this new diff does.

M4 was on the track all day at the Speed District event in stock form and performed without a hiccup (albeit tires) in ~110F heat. We'll be heading out there next time with the JB4 to see how things have changed.

Seems the heat wave is gone, so that's a plus.

R-compounds will be necessary to put all this power/torque down, a squared 275 or 285 setup should do nicely.

I'm a street guy. If I need non-street tires to put power down, I'm doing it wrong.

Haha, fair enough! There are some great super sticky street tires as well...Hankook RS3, BF Goodrich Rival's, Advan AD08R's, etc.

Throw on a 305 in the rear with any of those compounds and you should have a great amount of grip for the street.

Congrats Tom! Can't wait to see how this performs at the airstrip. Going to Shift Sector and NFZ?

I should be running the RS-3s in 305 soon and then will try out the R888 to see how they compare.

I think he's doing both. I will be at NFZ.
