After hundreds of qtr mile runs, this car is running as smooth and strong as ever. Still gets 30mpg+ on the highway, and to the street competition, it looks and sounds like a mellow 11 second daily driven family sedan. So much fun!

Did three back to back test runs. All 123.5mph.
This is remarkable because its probably the highest recorded traps on stock turbos (w/o N20), and back in the Sac glory days, this definitely would have been over a 126mph trap.

Definitely the fastest recorded traps on stock intercooler and the heavy rear factory exhaust and catalytic converter.

Same Map 3 settings that I always run. This is not the newest firmware. I'm kind of afraid to change it since the car is running so well!

52F, Calm (Cooler temps FTW)
Chevron 91+dual nozzle 100% meth.
JB4, Map 3 w/FSB.
17" K1 with NT05R rear tires.
Approx 3500 lbs running weight w/driver
All very soft 2nd gear launches with slight wheel spin.

Run1: 11.9 at 123.6mph, 2.1 sec 60'
0-60:3.7 sec, 0-100:8.2sec

Run2: 11.8 at 123.5mph, 2.0 sec 60'
0-60:3.7 sec, 0-100:8.1sec

Run3: 11.9 at 123.5mph, 2.0 sec 60' (CSV0827)
0-60:3.7 sec, 0-100 8.2 sec

Meth FSB is working flawlessly. Smooth with no quench problems, etc. Just pulls nice and strong as heck when on full boost. Had a splitting meth line leaking last weekend, and the boost was cut...traps went down to 119mph.

Also, I'm quite confident if I unplugged the meth pump, I would stil be trapping over 116mph.

Yes, traction is my ENEMY. But the runs are as consistent as can be.

[themyst]

Did I read that right? 3500 lbs WITH driver? Sure explains a lot.

You also have a freak car Good runs!

What's your car weight? Mines was 3420lbs (1/2 tank and no driver) at my last track event. (Only major weight saving mods are AE exhaust and Morr wheels)

[Jeff@TopGearSolutions]

My car is 3490lb without driver. That was a 1/4 tank of gas. I dont have Navi or any other premium or cold package either.
What else is out of the car hotrod?

[V8Killer]

Is that peaking 18lbs? What do you have your additive set at? Sorry iPhone app can't blow up the pic to see it better

What does it actually explain?? All the fastest stock turbos, 335i BMWs have the same weight reduction. And most of the top 135i times were done on weight reduction that I can't match in a 335i.

Actually, its not that simple. If you are trapping 116mph, take out 170lbs, and I can guarantee you are not going to be trapping 123mph+, LOL. On the other hand, put a 170lb passenger car and see if you lose 7mph in trap, it isn't going to happen. Got a Vbox? Go try it! Let us know the results.

Besides, a stock weight 135i is lighter than my car. And as far as I know, there aren't too many (if any) reduced weight 135i BMWs on stock turbos, exhaust, intercooler trapping 123mph...so weight is not the guarantee of good performance. I have put on heavier RFTs, put 100lbs of Salt bags in the back of my car to try and enhance traction. And guess, what...easily 120mph traps still. I can't tell you how many times I have pulled out my passenger seat expecting a nice trap speed improvement, only to be disappointed.

In General: 100lbs=1mph, .10 sec, 10hp.
So you may decide to pick up 17hp with your intercooler and fully catless aftermarket exhaust instead of dropping 170lbs. You can approach it however you want. I prefer the approach that results in better handling, better mpg, responsiveness, and is easier on the drivetrain.

There is more to maximizing performance than weght reduction. Remember, I set the trap/ET record for tune only, full weight, (besides DRs.)

Passenger seat removal, 17" wheels, and always run with less than 1/4 tank.
Again, still heavier than a 135i, much less a weight reduced 135i.
Still have the heavy stock catback exhaust. I would change the exhaust for the weight reduction alone. But on the other hand, my car is very mildly modified, in the sense that very little cost was involved, and the car can be returned to stock in a few hours..(the DPs being the most difficult modification).

Probably peaking around 18, and tapering up top to 14-15psi.
I have always used a 50 additive as my daily driving setup.
This all on 91 octane Chevron. Don't have 93 octane around here.

[V8Killer]

Nice.....im getting ready to install my meth and was thinking I would try those settings as I have 93 here

[Sneeze]

nice!!!
have you ever tried to do a little burnout just to get those 60' to 1.8-1.9 range? i was thinking about of doing it. lol.
heres my best vbox run. and with some ms109 traps would be around 123-125mph.

You will love the meth. In cooler temps especially, the car is so responsive. You get a kick out of it driving around town with explosive acceleration so readily available.

Nice run! What mods did you have? I generally haven't seen much improvment with race fuel on meth. Perhaps .5mph?

But no....I don't ever do any warm up burnouts in testing. And as you can see, I always let the car shift by itself at redline. More for testing consistency than trying to get the absolute best perfomance with results varying all over the place.

fbo+meth. weather was in the mid 50s.
first gear launch and shifting points around 6.5k-6.7k rpm.
nto5r tires. ive never seen 1.9 60' with these tires in my testing unlike the 555r.

Wow, I'm really beginning to doubt these NT05Rs. I saw 1.9s on the 555Rs also. (no burnout). I'm just driving the on NT05Rs now since I pretty much don't have much tread left on the NT555Rs. Although with a "0" tread wear rating, I am sure these NT05rs are going to be worn out really quick on the street. But the car is almost dangerous driving on my regular 19" setup. It spins the tires even when you gas it in the 40-50mph range.

For the street, its hard to beat the NT555R tires. I'm just not positive it the NT05Rs are supposed to be better at the track with a big warm up burnout compared to the NT555Rs. I am suspecting the Mickey Thompson ET streets might be the best for the track though.

Absolutely great results. You have a PM.

Holy hell, that's light as f*** w/a driver!

[dzenno]

Great results as always hotrod! Simply unreal

What do you weigh man? My car after all the mods and all seats kept in is 3540 on half tank so about 3500lbs no driver and 1/4 tank..I'm 220-230lb

You should be lighter than that with your mods. What wheels/tires are you running? Remember 1lb of unsprung weight = 10 lbs of regular weight.

[datbimmerdoe]

stock turbo, intercooler, n exhaust w/ cats? oh. muh. gawd.

[Mike@N54Tuning.com]

Great runs and great log. Timing looks fantastic, boost curve looks great. Must be a fun car to drive even though you have beat the #$%#$ out it over the years she still keeps pulling strong.

I weigh about 176lbs. So not really heavy or super lightweight. I am just estimating the weight as I never weighed it in this configuration with seat removal and 17" wheels. In all reality it probably does weigh more than 3500lbs with me in it. Just stating it to emphasize weight reduction. But also to emphasize it is probably close to the weight of a 135i.

The car is running in the high 8's in the 60-130, which is excellent for stock turbos.

I'm really intrigued with your testing of the 60-130 testing with the RBs. I'm glad you took the time to test and log. I wish others would run these tests also. Far too many times, I have seen dyno queens not measure up at the track or in real world races. With low 8's in your car, you have to be trapping around 127mph in the qtr mile. Did you verify the qtr mile trap yet? Based on how my car feels, your car must feel like a monster. I have never run N20 on this new firmware, (with the FSB) which seems to make more power down low, with substantial taper up top. I think it would be faster on spray also, but Im not sure all that power right after the shift will be good for the trans.

I really do need traction, LSD, and a good track. I would love to see what kind of ETs I could get if I could give this car full throttle on the launch.

[jpsimon]

I need to get to a scale, anyone know how much. an XI weighs with sports package, cold weather, and navi?

I think XIs weigh almost 200lbs more! But I really think if you have the power, your ET will benefit with the ability to make some full throttle launches. Even better than running on drag radials, without having to deal with expensive tires wearing out so fast. Probably get some insane 0-60 times too. If my car had the traction of AWD, I'm sure my 0-60 times would be lower than 3.2 seconds. Probably in the 2's. Soon as a XI owner with a very high power N54 on nitrous, or RBs runs at the track..10's are going to be an easy thing.

The only type of race the AWD will hurt you is in the higher speed roll ons.

But don't overhype this weight thing. Think of it, the total differences are the same as carrying a medium sized passenger. Will having that passenger get out of your car suddenly transform your performance by leaps and bounds? Of course not. But on the other hand, don't be racing someone else with no passenger when you have one in your car!
