We had our M2 on the dyno this week to test out a few new upgrades. After finishing up the tuning on our Mustang dyno we drove over to a local shop to get some Dynojet numbers.

The car currently has our prototype downpipe and intercooler installed, and with some information provided by our friends over at TTFS we reflashed the ECU and are now running a consistent 15-16psi at the intake manifold. The fuel has been cleaned up and now richens sooner with a nice taper at the end. With an additional 3-4psi the car is going to make great power.

We plan on having our complete exhaust and meth system complete next week as well, so stay tuned for updates!

378/414?

[135iDCT]

meth + 93oct

Nice!

[NameLess2756683]

The power that was generated was done with no intake mods? I note that is the one area that BMW improved over the M235i.

What fuel is that on

This is on 93 octane only.

Bone stock intake.

Any plans of e85?

[zenmaster]

So this is prob max reliable to expect with a flash tune on 93oct w/ downpipe and intercooler?

[SukSqueezeBangBlo]

378 whp 414 wtq with tune, downpipes, intercooler and 93 oct gas? Sounds pretty good. With a final tune and some tweaks this car is going to be pretty strong with meth or e85.

What were the stock numbers on this dyno?

[DrKevM5]

So when will the intercooler and tune be available?

We are not finished with the tuning, and expect to extract a few more HP over the next couple weeks. ETA for the parts should be roughly two months. We should have our full exhaust system prototype finished by the middle of next week and then we'll be back on the dyno again to finish everything up.

Is this a catless DP? I was just comparing this dyno to the fabspeed one with sport cat on stock tune. It looks like peak torque is about the same, though it looks like you guys sustain it a bit longer and hp is up about 30 or so. Idk, I just expected a tune +catless DP would yield more drastic improvements.

Yes, this is with a catless DP. We are running a very conservative 15-16psi and we do not ramp boost very hard down low. Our car needs to be able to withstand a 25-30 minute hot track session without any hiccups. 30+whp is a lot, especially up top when we're only running 1-2psi more than stock with a richer AFR as well. The stock tune runs pretty lean down low so we've added a bit of fuel to keep things cool. For example, using our Active-8 in combination with our reflash, we were able to see 462lb/ft and nearly 400whp by turning the boost up a bit.

What did the car make stock vs tuned ?

With Sports CAT DP, intercooler and tune you are looking near 400whp?

Bone stock our car made 330whp on our dyno as documented here: http://f87.bimmerpost.com/forums/sho....php?t=1252662

I'm not sure about a sports cat dp, but with our catless dp, intercooler and tune 400whp should be achievable.

[Norcalmav23]

I personally find this pretty encouraging. Active 8, fabspeed DP, and bms intake all for under 2k and we should get 60+ HP and 80+ TQ on 93oct with amazing sound?! That's a big time win! I don't plan on tracking the car so I will pass on the intercooler. Just a guess but if a stock m2 is running 12.7's in the quarter mile I think a stage 2 will easily get to the mid 11's

Very impressive.

Does the different intercooler change the throttle response compared to stock ?

Considering there is a grand total of 1 m235i running mid 11's and 1 435i running 11.7 using race gas, Pure Stage 1 turbo, upgraded fuel pump, race gas and FBO you're most likely going to be disappointed with 1/4 mile times following tunes and mid 11's while possible is going to be far from easy, just as it is for other cars with the N55. You will have issues launching the car without drag radials and will most likely create a scenario where you took a beautifully balanced track car and overpowered the tires.

[FSociety]

378whp / 414wtq 14-15psi seems like what another M235 FBO just did with 91 octane in SoCal at 14psi though.

Active, do you guys have the Dyno on the Dynojet graph I saw the previous post was on Mustang Dyno. Not sure how to compare 378/414 without seeing what it did on the same dyno before the tune and mods ?

Cheers

Good points, daaaaahhhh
