Took her to a "Dyno Day" event last weekend. I neglected to confirm that I was on Map5 before handing the keys over, and after a service visit at the dealer I forgot to change it back to Map5, so I got a somewhat baseline on Map 0 instead. Mods include:

JB4 - MAP 0
VRSF catless DP w/ MPE
VRSF FMIC 6" Race version
VRSF CP
BMS Intake

Car is a 6MT, Elevation at the shop is about 1300ft, and it was hot AF inside the shop, so I'm pretty happy. IAT's wouldn't go below 100*F!! Shop must have been 120* inside we were all swamped by the end of the runs. Only getting about 1-2* of timing with those IAT's as well. Was a good time and am happy with the outcome.

Pure Turbo Inlet and Meth going in next week. Will probably re-dyno next time I go to the coast, or in the Fall on the next Dyno event. Hoping to get it up around 380whp or higher. Thanks to all who've helped me along my journey, thus far!

Thanks, I'm happy with the report. Been driving it pretty hard on the roads here and it's making up to 17-18psi as opposed to the 12-14 I was seeing on the dyno. Only this time with 11* of timing instead of 0, lol.

Is that with the methanol?

No, just Map2 instead of Map5. The meth kit goes in later in the coming week

That's the dyno result of map0? Wow, is a lot over stock spec. Wonder what map2 or 5 would get.

[SeanWRT]

Ok I'll be 1st one to look at facts here.

It made 310+whp over only a small dip at 5k and lasted less than a period of 200rpm. In this sense, 310whp is a better and more representing number for baseline. Given the fact that dynojet adjusts to altitude, there is nothing to be happy with seeing around 315whp decatted. That leads to 300-305whp or so when stock, which is the typical American number with m235i we have been seeing.

Next time with more bolt-ons installed, run map2/5 to know the delta, the only thing that matters.

Everything is typical, yes, aside from the 107*F IAT's causing full timing pull. The car would have put down more if the intake temps would come down, best we could get them to was 107 after loading it up for some time.. If the car was stock it would have put down under 300whp on this particular day, due to namely the heat.. There was also a WRX that put down 360whp, meanwhile two months ago he made over 400 on the same dyno, same fuel but just a cooler day. This is why I don't get bent out of shape over this stuff.

I'm very happy because it's running well, and is running better on the road than what you see on that sheet. Dyno #'s mean very little, as every report will vary and every dyno, day, and location will change the result. They have a sister company in Vancouver of which the shop owner claimed that location will make 20-30whp more just due to being at sea level and having a cooler climate. There are too many variables to consider with Dyno's, and I could care less if the car could or should have put down more. The writing is on the wall, if I can still make over 300whp/350tq with extreme heat soak, pre meth, I'm pretty happy!

Again, dynojet adjusts to ambient condition including air temp. 107F is far from the point where DME would do protective timing pull. Therefor in this particular case of yours, given temp delta is minimal thanks to bigger IC, you will NOT see a higher number even in a much cooler day.

BTW, take a second thought about what that shop owner said.

The car was making no timing advance whatsoever, and stock boost, seems pretty logical to me. Once it was on the road, was making 11* of timing, again. But wouldn't on the dyno. How do you factor out timing pull from heat soak? The car can't take any more bolt ons, is FBO aside from meth which was my whole point of taking it in that weekend. The Map0 dyno was by accident, and honestly I have never had 41"C intake temps on a dyno, ever (I am not talking about ambient shop temps, which were much higher). I rarely see higher than 25-30*C IAT's when I'm on the road, so it goes against what you're claiming will happen. This isn't my firs rodeo, by the way.

I appreciate your input, though.

That's so strange, or maybe I'm the strange one. I never seem to hit above 13-14 on map 2. Fbo and good quality 93 gas.

I have seen other guys hit pretty high boost on map 2 as well.

[SeanWRT]

Dylan,

let me put this simpler - 310-317whp on Dynojet are adjusted numbers that already reflect your car's performance in real world where timing is advanced and boost is higher.

Your findings are very true, which I appreciate, but they lead you to untrue conclusions. Let's stop from here if both our points are well understood.

BTW, turbo Inlet is a great bolt-on with your boost level. Do a comparison dyno. Good luck!

Yea it's not holding 17 just spiking for a few hundred RPM and sticks around 14-16 for the most part, but that's 2-3 more PSI than I ever see on Map5. That said, Map5 feels stronger from start to finish, and more linear as most have reported. Can't wait to get the meth hooked up!

Understood, and there's only one way to find out

I don't have mine hooked up currently . I decided to go from single cm 10 on 50% meth to cm 5 and 7 on 100% meth. After I swapped nozzles, I was having some issues with leaks and with purging the system properly.

I am going to move my solenoid as close as I can to the nozzles. Also I'm going to replace PEX tubing with stainless braided lines and an4 fitting for safety and longevity. Still trying to figure out which lines and fittings to go with though.

[FSociety]

SeanWRT agree with you but this is Dynocom not Dynojet.
Dynocom reads happier than DJ btw

[XutvJet]

100+ degrees ambient temps? Yeah, that car is down on power, correction factors be damned. There are plenty of dynos out there of N55 cars, especially M2s, showing rather low numbers under hot/humid ambient conditions. Yes, dynos can and do correct for density altitude (DA) conditions, but there's no correcting for how an ECU is reacting under those conditions. Most late model turbo cars, including BMWs, get quite conservative on the power control to reduce the potential of a detonation situation, especially a low speed pre-ignition (LSPI) which is a big problem in a lot of direct injection turbo motors (not necessarily BMWs though).

Exactly our thoughts, too. I was actually getting 107* Intake Air Temps, Ambient was higher inside that shop!

Again, I'm not unhappy, I get all of the factors and that's why I am good with it. The car was literally making no timing even at 6k rpm, and that alone tells the story of power loss. I know Dyno's correct for ambient temps and altitude but they can't read an ECU, or factor in timing pull and boost, but I can read a log and tell what was happening and the reasons behind the final number.

Will be tapping into my washer tank and running my feed from there. Everything will be wired as short as possible to mitigate any unnecessary routing and make for easier diagnostic if I ever run into trouble. Never had an issue with the plastic tubing, and I usually run it along the floor beside fuel lines, etc, but for this car I'd like to keep everything up front and in as "oem" in form as possible. Hence the low fluid warning via washer tank, and stealth pump install under the frame rail.

I plan on the single CM10, with a 50/50 water/meth blend. Hoping for good times

Dylan86 props for taking your car to Dyno at least majority of others don't and think their cars makes the same power as the next car (WRONG).

107F IAT starting or at the end of the run?

Thanks man, appreciate it. Once warranty is up I'm probably going with the Bootmod3 flash as well

The IAT's were tracking about 113-115 when rolling freely on the Dyno. He was doing his best (the operator) to load the car for at least 20-30 seconds before each pull. He even waved me over to show me what was happening. I asked him to press "Start Logging" before each run but he forgot probably because it was f'in hot inside my cabin and I didn't get a record. When I was in the car and under load on the "pre-run" we couldn't get it below 110*F the run itself I saw the lowest number which was 107*F (41*C), which is about 10*C higher than I've ever seen the car run. Sure enough I had my eye on timing advance and it might have hit 1-1.5* for the entire run but that was all the way up top once the run was basically over.

Do you think water/meth would remedy this completely, or only partially? Cheers

Yes Water/Meth injection will definitely fix this cooling issue.
Also, were their fans adequate? If not I'd go somewhere else for Dyno and look for a Dynojet instead.
Why didn't you just grab your mobile and logged each run ?

They had three of those high powered fans, but honestly the air was so hot it didn't seem to matter. We were all sweating profusely inside there, and the air from the fan just felt like hot blowing air, lol. They have some air circulation issues to sort out, and I may not return until they do so.

I tried standing with the phone in my hand and I kept disconnecting via bluetooth. It was a "Dyno Day" event and that machine is buried in the back of their shop, with a chained off entrance about 40' away, which is how far away I was standing when they ran the car. Video was done by their staff. It wasn't until he called me over that I was able to take a look at what was happening, live. Sure enough I found out after that he didn't log it as discussed beforehand..
