Denver guys,
Anyone up for a few runs at Bandimere this weekend? It's $35 for a full day, test and tune, they call it.
I'm not a big drag strip guy, but I'm curious how we'd fare up here at 5k feet. It's Saturday, all day. I'm thinking about heading over around 9am and staying until lunchtime.
Should be a blast! Anyone interested?

This is drag-noobie question. The bandimere site says you need the following to race the 1/4 mile. Do our cars have these? If not, I assume they are pretty simple to install. Anyone know for sure?
"
I have a street car. What do I need to come out and test or race?
The basic items needed to pass tech inspection for the typical street car include good tires, a battery tie-down, radiator overflow catch-can, operable neutral-safety switch, seat belts, and a valid state driver's license or NHRA competition license is required for all participants."

For your car, all you need is a helmet.

Its my Professional Engineering (P.E.) exam. 8 hours, I have been studying the past month for it. I mean what else would I rather be doing on a Saturday then sitting in the National Western Complex taking an exam :thumbdown.
And yes, you will need a helmet if you are running in the 13's which with your mods you should be easily doing, if not dropping into the 12's hopefully. I don't know how much the altitude will be affecting times though.
Me and a buddy are thinking of starting up a car club so that we can race at the club clash drags. I will let you know how this goes if anyone is interested.

I definately cannot go tomorrow: need to get alignment done, and the drop on my car is too severe - so I have to take it back to MAC for adjustment.

So this was my first time drag racing and it was fun but a little disappointing. The track was a lot slicker than I expected. On my first run, I got pretty sideways before I realized I needed to let off the gas to avoid crashing into the wall (DSC/DTC were off). I got a 15.6@101 and got beaten by a Civic! :mad0260:
Next I tried a more conservative launch and got a 14.7@103. Then I tried a faster launch with DTC on and got a 14.8@103, and my last run was 14.7@104 with DTC off again. I just never could hook up very well. My best 60' was 2.547 (2nd run).
Traction issues aside, I'm not too convinced that the Dinan tune is performing all that well at this altitude. forza1976 has the SSTT in his 335xi seems and he ran a 13.7 today (were you on 91 octane?). We've played around on the street a little too and I was never able to pull on him, even from a roll.
We saw a Barrique Red E90 and a Space Gray E92 today -- were those any of you guys?
Another question: I was redlining in 3rd when I finished. Should I have been in 4th? I figured it would cost me too much time to shift given that I was so close to the finish.

Thanks for posting the results!
Looks like you were definitely having a problem putting the power down. Do you have the all-seasons or summer tires? When temps are in the 40's like they were today, the summer tires are basically useless unless warmed up. Those 60' times are definitely not helping your times. How were you launching? You shouldn't shift unless you absolutely have to as it will only hurt your times, but at the same time you aren't at your maximum hp above about 6500rpm and should probably shift.
I'm guessing the space gray was 335trackaddict, don't know who the barrique red is though, haven't seen one of those around.

JT, don't get too down... First time at the track is always tough, I have been there so many times, all the high school drags and the test nights that I did. It all comes down to just getting the launch correct. With your trap speed you will wipe me and I bet you get mid 13's. I was on straight Safeway 91 octane, gotta keep with my 10 cent per gallon discount.
I weighed the car after my last run and with me in it, it was amazing a solid 3900 pounds with about 1/4 tank of gas.
As for what gear, I was just about 6800 rpm at the finish so. I would hope you don't have to hit 4th as that will take time away from the ET. Was damn fun, sorry that I had to leave so early, Melissa was cold and I needed to get her home.
335TrackAddict, sorry that we missed you. We saw your car but didn't see you run at the track. What were your results?

I was on Goodyear Eagle F1 GS-D3 summer tires yesterday (265/30/19). I know the temps weren't helping so hopefully I'll do better when it warms up.
I revved up to about 2k when I launched, except for the 2nd run when I started from idle. The first time I just floored it immediately since I can get away with that on typical asphalt. In the subsequent runs I tried to modulate the throttle based on how much traction I thought I was getting. My tires were totally silent when they slipped so determining traction was hard too.
I definitely have lots of learning to do but it's kinda hard when you have to wait an hour or so between runs. Might be nice to go some weeknight next time.

Hey guys - sorry I didn't get there in time. We'll see each other at the car control clinic in a month or so. Also there's an auto-x next weekend if you guys are interested. It's not quite as fun as the road course, but it's a good substitute.
My times weren't that great. I only did two runs as I got tired of waiting. 14.5 or so, but trapping in the 105-106 range.
I tried to run my r-compounds in the back, to see if I could get better grip. Bad mistake.
The temperatures surely didn't help and I could not get them to warm up no matter what. I'd do a non-water burnout and even after doing a run, I stuck my pyrometer into the tire and only got 105 degree temps! The tires don't stick till 160degrees, so as you can imagine, I literally spun 1st, 2nd and top of third. My tail was wagging 1/2 way down the strip! It was nuts.

So what mods do you have? I only had traction problems in 1st (I think) so you must be putting down a lot more power. It can't all be due to our tire differences since you still got better times than me.

I've got V2 and a high flow cat.
I'm putting down about 320whp uncorrected last I checked and I did a few more tweaks to the map since then.....so probably in the range of 330whp.
If you want a more direct comparison, we can check our terminal speeds at Pueblo. As you might surmise, I can't launch worth crap. At Pueblo, there's a >1/2 mile front straight that you enter ~60-70mph. You virtually remove the wheelspin and it's a long pull that you do about 16 times a day when you add up all the sessions.
I can let you borrow my logging chip and we can view the terminal speeds later. I typically hit 135-137 mph indicated (~133mph real) on that front straight. A stock car hits about 123-125mph indicated.

Here ya go. Note that this was an original version of V2 (2.01?) and therefore had the torque dialed down considerably from V1. Oh and there's a noticable boost drop above 6500 rpm that Shiv implemented after my problems on track with high rpm lift-related limps. He's since dialed up the boost up high and resolved the limp issues there in other ways.
I think Shiv intends to dial low end torque back up with V3. But personally, I like it nice and "low" like that, because it makes tracking the car much easier.
This was done in Denver.

Yah know, I don't really pay much attention to corrected, since it's a correction factor for NA (I believe).
If you take your percentage correction and apply it to my uncorrected numbers, I'm pushing 385-390whp, which as much as I'd like to believe, I don't, lol.
How much more does the sedan weigh compared to the coupe? When I go to the road course and put on my light wheels, I'm 3480lbs with 2/3 tank of gas and no driver.
BTW - you guys should consider coming out to see the BMW autox tomorrow. You can see the info at rmcbmwcca.org
I'll be driving, but I am by no means good at auto-x. There's another guy there with a bone stock E90 335i that whoops on just about everyone, including me. I don't think a stock E46 M3 has ever gotten close to his times. He's damn good.

As stated earlier, I was trying to run my r-comps on my RWD, which are absolutely worthless until they heat up. I spun through 1,2 and top of 3rd.
ET is based on drag strip driving skill - of which I have none. Most of my track time is on a road course where you aren't launching at all and you don't power shift.

I agree that the correction is for NA cars so shouldn't be applied to ours. But your numbers are great considering they're uncorrected and we still lose a lot of power at this altitude. I need to re-dyno my car soon but I doubt my numbers will be close to yours.

I really think that the Procede is best for us here at altitude. It produces far more power than any other solutions (another guy in Denver with an AA Xede is producing about 285-290whp uncorrected).
Regarding reliability, it's error free on the street. I have had issues in the past on the track, but generally because I crank user settings up too high. I've had it for over a year and nearly two dozen days on the road course, so it doesn't blow up your car, lol.
Weight wise, the only other thing is the high flow cat, which probably saves about 5-10 lbs max. My track wheels are around 16 lbs though, so I'm saving 15 lbs a corner. My R-comps are heavier than the stock runflats (which aren't that heavy, despite people's complaining).

In my opinion, the warranty fear is overblown (no pun intended).
Quite a few of us have spent extended time on track, where you're running nearly full boost for 20 mins at a time, multiple times per day. I've personally logged nearly two dozen days with more coming. And on the original fuel pump!
Dinan's warranty isn't the ironclad guarantee that people may believe it to be. On the E46, I am personally aware of people who have had their Dinan warranty voided because of an aftermarket exhaust. Now, you can pay $2k for a Dinan tune + $2k for a Dinan exhaust + $xk for an intake and then retain your warranty....
But that's akin to buying a car bra for $1500 to protect your $500 front bumper. Insurance is a probabilty game (warranty is insurance). Take the cost of buying the insurance, multiply by probability of failure and compare it to the expected cost of repair/replacement. That's a generalized description of how actuaries determine proper rates for insurance companies.
The fact that I've been able to flog the 335i over nearly two dozen track days should indicate that the probability of failure is far below anything meaningful for the average non-track user.

I can't really argue with any of that. I feel like I might have a longer-term reliability advantage, since Dinan supposedly tapers off the boost at higher RPMs to preserve turbo life. But I guess it'll be a long time before I'll know. All I can say is that if I had known I could get results like yours at this altitude, I would've been a lot more tempted to get the PROcede.

Anyway, Trackaddict's view on insurance is logical with respect to the population of people involved. I think more "personally", and I only insure things that I cannot afford to replace.

Don't get me wrong, I don't have major regrets or anything. It just makes me think twice when I consider how many more kilobucks I'm gonna have to cough up (continuing to go all Dinan) to get 345 whp in this thin air, if that's even possible.
Speaking of which, I see you have the Dinan exhaust too. Have you dyno'd it yet? 1/4 mile times?

I think you might have a very hard time reaching 345whp at our altitude based off of DrEvil's dynos. With his Dinan S1 and exhaust he is dynoing (uncorrected) 265whp. So you need another 80whp from bolt on mods, which I am just not sure is possible with our stock turbos.

You are probably right. But then again, the dynos seem to be optimized for N/A engines at sea level, so who knows what they really mean, plus I did not do a baseline. With all corrections and fudge factors, I calculate I am getting 407 hp at the crank. That, too, is irrelevant. Then, you might want to see my 1/4 mile - but what good is that without an experienced driver doing the run?
So, statistics are just one component of my Dinan value equation. The others are the feeling this car has now, how it differes from stock, and the warranty. Maybe track performance, if I get around to that.

Woah there. JTM has a 335i while DrEvil has a 335xi. That alone is good for 20'ish WHP, as proven on the dyno by JTM and forza. So it's not an apples to apples comparison.
To DrEvil's point, the dyno CORRECTION FACTOR is to correct to equivalent sea level power for an N/A car. That's why it is so imperative that you use uncorrected numbers for comparison. Uncorrected numbers are not affected by altitude because (on a dynojet) it's simply a calc of how fast it gets the heavy dynojet drum spinning.
I believe forza, on the same MAC dyno, got 242'ish whp stock (uncorrected) with his 335xi. Since ambient conditions were similar between DrEvil's run and forza's run, we can safely say that the Dinan tune + Dinan exhaust gives you about 23 whp increase.
Not sure where you got your 407 crank HP value. Being that you got about 265whp uncorrected, if you tack on the (admittedly incorrect) correction factor of 1.24, you're at 328whp. To get to 407 crank HP, that assumes a 25% drivetrain loss, which I hope to high heaven is not the case with BMWs.
By that same math, my car is making 492 crank HP.
Regardless, the track test I suggested to jtm earlier will probably mirror the dyno results, or maybe not. At Pueblo, we will come out of turn 10 at 60-75 mph, depending on driver skill and top out at 130-140mph at the end of the straight prior to turn 1. To completely eliminate driver skill, we can use my logging chip and log the time interval between 70-105mph, which happens entirely in third gear.

Actually forza got 223 and I got 242 (we were both stock at the time).
Just to correct the record, I thought for a minute that you had dyno'd at 345 whp but now I see it was 345 lb-ft (~320 hp). Still damn impressive, and enough to make me just a little jealous. :)

Ouch, I'm cowering in the corner with those low numbers... Don't laugh guys :(

Don't worry forza, you're still faster with your fancy AWD. ;)

I went yesterday, as well as last Saturday. Best time so far was a 13.5 @ 105 with a 2.1 60ft. I mixed in some race gas at the end because I was getting some stumbling. Not sure if the fuel pump is going, or if its the AA piggyback. ALl I have right now is a turboback and the AA Xede with the R07 downpipe file, on runflats.
How many of you guys are having issues with your tunes and the altitude? We are working on a factory ECU flash tune that is altitude specific. No ETA as of yet, however.

I've got V2 and a high flow cat.
I'm putting down about 320whp uncorrected last I checked and I did a few more tweaks to the map since then.....so probably in the range of 330whp.
If you want a more direct comparison, we can check our terminal speeds at Pueblo. As you might surmise, I can't launch worth crap. At Pueblo, there's a >1/2 mile front straight that you enter ~60-70mph. You virtually remove the wheelspin and it's a long pull that you do about 16 times a day when you add up all the sessions.
I can let you borrow my logging chip and we can view the terminal speeds later. I typically hit 135-137 mph indicated (~133mph real) on that front straight. A stock car hits about 123-125mph indicated.
stock can hit 128 mph with a perfect execution of turn 10 and a wait, wait, wait, oh shit! BRAKE! to the entrance of turn 1. Turn 10 has changed now and the entrance is slower so I would expect a lower speed all the way around this year at the end of the straight. :D

Haha, I know the feeling.
Perfect execution of turn 10, to me, is "ignoring the wall and going big". :) On R-comps, I'm comfortable apexing 10 at exactly 70mph, and holding off on full throttle until I hit the left side of the front straight. Call me a wimp if you want!
They actually changed Turn 10 back to the original configuration. They were going to make it a 90 degree super tight turn (2nd gear) with a 15 foot wide track at apex(!!!!!), but them the motorcycle guys basically said they would never come back, so they just repaved the original Turn 10.
I'm headed to NASA next weekend, so I'll let you guys know.

Just checking if there are any 325/328/330 times at bandimere yet?
