EVOLUTION OF POWER

Fireballed! Racing is the official motorsports program of BMW NA/MINI USA and we have been in partnership to develop programs to promote the MINI Cooper platform in the lifestyle and performance segment of the Sport Compact industry. Our project vehicles are currently the fastest and most powerful street and race MINIs constructed and we have developed and tested innovative components and assemblies. In our quest to push the limits far beyond what was originally intended or expected, we have also expanded our knowledge of the platform and our approach to product development and factory integration has been evolutionary.

In 2007, we will be continuing our efforts to push the performance envelope of the M600 Race Car and will be incorporating new technologies and components into the program that will raise the bar once again and continue our success in showcasing the versatility of the platform to industry leaders and automotive enthusiasts.

The purpose of Project "MARY" is to provide insight into the inner workings of building a successful program and the effort that is required to design, manufacture, and test prototypes and production components and/or assemblies. Project "MARY" will evolve and eventually integrate into our race program and its success and potential will be showcased at the NHRA Sport Compact World Finals, Oct. 20-21 at Pomona Raceway, Pomona, CA.

Testing performed on DynoJet Chassis Dynamometer



Baseline testing on stock vehicle yielded 169.47WHP.
As a reference, we included data from a MINI GP which made 178.48WHP at 7100 RPM.
The stock vehicle made 158.40WHP at the same RPM point.

Next, we replaced the stock cylinder head with our Fireballed! Stage Three Race Head and returned to the dyno a few hours later.

With only a cylinder head change, "MARY" mustered an incredible 202.98WHP at redline which equates to a whopping 33.51WHP increase!! in peak WHP.

As a reference, using the GP data at 7100 RPM:

 

Wow. When I saw this thread title, I thought Kris (GBMINIGIRL) was getting her MC Fireballed. She has a site called "ProjectMary.com".

 

What RPM was used to compare?

Why that RPM?

What was the RPM limit increased to?

Would it be possible to overlay the RPM on the graph please.

From the graph it looks like you could have chosen a slightly higher RPM to acheive an even greater delta.

Thanks for sharing your research.

 

 

 

Oh yeah...where are the torque figures?

 

THAT JUST HAPPENED!!

Way to go guys.

 

Bit of a pain but you can work it out by; HP divide by rpm x 5252

 

 

If you see the black line going from bottom to top this is where the GP rpm limit kicked in.

 

You got me on that one

Okay first you have to go; mph divide by .01239

 

 

 

 

Some omniscient being.....

 

I think its interesting that;
and
yet;

Is there anyone else with a professional drag race MINI besides Fireballed! ? Put in that context this;
doesn't really mean much.

 

I thought that another FB car, "The Widow", was primarily a street car, but also could be run on the track or road course, and thus would qualify as a "race car". Thus, one wouldn't need to restrict the concept of "race" to the drag strip. If so, then the claim by Hubie would still be valid, at least at this point in time. Perhaps someone from FB Racing would comment.

Thanks...

 

maybe there are other drag minis that you dont know of

 

Can we keep it on topic? Take the pot shots on PM.

Hubie-
What is in store for Mary next????

 

The RPM was increased to 8200.
I appreciate that you have the insight to see that this is not about choosing numbers to show the largest deltas. We used the GP redline just as a reference point. Unfortunately, the tach pickup was acting up at high rpms, but i will post rpm graph and torque data.

Nice work Hubie and Brian. Keep the good news comin'.

 

oooowwwww, prudy!

 

Is the Stage 3 head suitable for a street driven car?

That's an amazing gain considering stock header & exhaust, congrats!

Just curious, what octane fuel was used?

Thanks!

 

Thanks! Its sure is street able, we did those pulls on 91 oct
