M2 stock dyno testing on 97 and 99 RON Fuel
We finally got our running in service done at 950 miles (couldn't wait any longer!) and drove straight from the dealer onto the dyno. During the the running in we mostly used BP Ultimate 97 RON (equivalent to US 92 oct) and the first dyno was carried out on this fuel. We then filled up with Shell V Power 99 RON (equivalent to around 93/94 oct) is our normal fuel of choice.
The result is not completely scientific but we tried to make sure the conditions were as similar as possible. It gives an indication of the difference the fuel makes on a stock car. evolve_bmw_f87_m2_lowered_dyno by Evolve Automotive, on Flickr Our dyno is a DynoDynamics machine which reads much lower than Dynojets. We do not use a correction factor to make them ready like Dynojets. The calculated flywheel BHP is very close to factory quote figures. We will get some VBOX figures as stock so we have a baseline of dyno and real world figures before after various tuning parts are added. Flywheel Power BMW M2 Dyno Graph by Evolve Automotive, on Flickr Wheel Power BMW M2 Dyno Wheel by Evolve Automotive, on Flickr So there is a difference of 6 BHP peak and 13 BP in the midrange and around 15 lb.ft torque through some of the power band. For reference a stock M1/235i will make between 333-345 Flywheel BHP on our dyno. We will get some comparison graphs up soon so you can see the difference. Over the coming weeks/months we will be developing the ECU tune (in beta testing), FMIC and downpipes so will provide data on these as we progress. |

What an interesting comparison, that's a noticeable increase with different fuel grades. You can see the increase mid range, right where the timing would be getting pulled on the lesser grade fuel and then again at top end. What's the dip just after 5000?do you think it's the ECU pulling timing or the dyno?

This site is a good start www.vboxverify.com but Dbsnanned corrected files are as good as you can get IMO. When are you doing the stock runs and what sort of ranges are you looking at? 0-60 0-100 100-200 30-130 60-130 1/4 mile? |

100-200 KPH and 60-130 we will be looking at. Will take it to Santa Pod at some point to do some 1/4's. |

Imran@Evolve how you getting on with the ECU tune etc? I've got a pile of mods waiting for after my break in period and wondered how youre going about the tune. Will you be using a piggyback or aftermarket ECU?
What mods are you making? What figures do you expect to achieve? Thanks in advance! |

Secondly: Is it safe to run the turbo up to the max like this for days to day driving, for non track applications? Would the stage 1 be the way to go without changing anything else I. E. Intercooler, dp,.. Or would you recommend these? Also, do you know the volumetric efficiency of the turbo? Just wondering if it's being maxed out. |

So far we think this is the most that can come from the stock set up. |

I don't think we will get plus 70 BHP with just bolts on TBH. Its early ays so lets see how we progress.
