This is from last weeks Helix Minisports Dyno Day - www.helix13.com
The only modification I have done is to put the Rogue Engineering exhaust on. Since this is the first I dyno'd the car, I don't have a comparison to what the stock exhaust would yield. I suspect there is no real gain, but the car does feel like it has more grunt. The exhaust was installed at around 6000 miles. I'm holding off on a cold air intake until I see some comparison tests in Grassroots Motorsports or another publication. Since it's still a fairly young aftermarket here in the States, I can wait a bit.

How did that compare with other MINI Coopers there on the day?

ddp · Dec 23rd, 2002, 03:17 PM

I was the only one with a Cooper that day, the others were all Cooper S. Helix13 did have a modified Cooper of their own that had previous dyno test, mine did okay against theirs.

What is the average power at the wheels considered to be?

Seems like those are pretty good numbers, maybe an exhuast is worth it after all?

ddp · Dec 23rd, 2002, 03:44 PM

Not sure about average power to the wheels from the factory, but the general consensus that day was that mine seemed a bit better than stock. Then again, I have heard that the factory numbers are underrated. And in the next issue of Grassroots Motorsports, they are supposed to have results of exhaust testing. The guys at Helix didn't think the Rogue produced any power in those tests.

Don't get too excited about comparing dyno test results. We have found great differences between dynos and even larger changes from day to day when the weather conditions change. The best use for a chassis dyno (unless you have one in a temperature and humidity controlled environment) is to compare changes and modifications done THAT DAY. It's a great tool if you test, do a modification and immediately test again, otherwise do what everybody else does and make sure you're comparing your apples to the other guy's old oranges!

They are also good for 'dyno day' head to head comparison between two or more cars in the same of different states of tune. But then again, if we're getting really picky, then the ratings first thing in the morning, high noon, and evening will all also be affected by the different conditions, but not too much to worry about for a fairly good head to head.

It is hard to compare dyno charts...especially from a Mustang Dyno.
Most places use a Dynojet (248 model I think???) and comparing two of those will be a lot closer. But it is good to get a baseline number so you can see what your mods are actually doing for your car.

stryder · Dec 28th, 2002, 02:51 PM

Am I just misreading the chart, or does torque and hp drop off at 5300 and 6500 rpms? Do you have a CVT, or is something else going on, since the car doesn't fuel cutoff until higher I thought....(and least on my 5sp...)

lotuseatsvipers · Dec 28th, 2002, 07:34 PM

5900 not 5300
edit: and in reality its past 5900 at around 6300 ish. Not right at 5900

ddp · Dec 28th, 2002, 09:11 PM

It's a 5 speed.

the results that you posted from your dyno run match pretty much what my baseline dyno from 11/11/02. I have added a Borla exhaust and Pipercross Viper Carbon Fibre CAI. I will be getting it dyno'd again about the middle of next month. I have been posting to this thread here on Mini2.com. Here is a copy of the best run of that day.

You will notice that HP & torque both tail off after going from 5500 to 6000 rpm's. All of my runs tailed off at roughly the same rpm's. This dyno was run on a DYNAJET, don't know the exact model number.

paddy,

I'll be curious to see how you dyno in the future, thanks for the link to the other thread, I had actually been following that one as well. Still wondering about my next step with an air intake.
