Went to the dyno this saturday with some local guys...Dynojet dyno, Pulled 197 @ 6600 ...only has alta cai, 17%, Volt w. center resonator delete, stg3 clutch and lightweight flywheel...pretty happy will have dyno charts up hopefull tomrow?

 

Assuming you have the R53, you got about 47 whp gain by just a pulley, cold air box and a light weight flywheel??!!

 

Kind of hard to say, seems to me that every cars is diffrent from the factory, if i recall ryephile had a verrry strong car.I've seen stock r53's pull almost the same as JCW.Guess my car is strong from the factory which makes me

Do you have baseline pulls? That will let you determine exactly how much power your mods made. Or, any other MINI's been on that dyno?

 

Dont have a baseline, just did it for fun, buddies E36 m3 pulled 218 on the dyno....

 

very nice for intake pulley and exhaust

 

You should get an RMW tune. If that number of yours is true, then you have one of the strongest MINIs.

 

Most 15% and Intake jobs get 188 at the wheels...his pulls 197 w/ the 17%, exhaust, and intake...completely believeable, and somewhat normal I would bet. 11whp (188 -> 197) out of exhaust and 2% extra reduction...strikes me as normal. Nothing particularly strong (or weak) about that.

Actually his numbers are way out of the norm. The base R53 puts out between 160-165 BHP then you have to take out the 12-14% drive train loss which puts you somewhere between 140-150 WHP approximately, depending on your car.

So putting out 197 WHP like his does is in fact way out of the norm. When you consider that he just added about 45-50 whp with only a pulley, intake and a light fly wheel it does sound sorta off to me, or perhaps the better word for it would be unbelievable. It just doesn't add up to me regardless of how his car came out of the factory being strong or not.

 

It is on a Dynojet also.. they read fairly high. Not really a wheel hp number.. more of a crank number.

 

Yep...I read 19 whp higher on a Dynojet than a Mustang in similar weather.

 

I did some research for a thread I posted in awhile back where I attempted to look up as many dyno results as I could where the person had only an intake & 15% pulley...a few had an exhaust as well. After digging up more than 10+ results, they were all within +/- 5whp of 188. The thread can be found should you care to dig through all my posts...ugh.

So for me, seeing someone at 197whp from stock w/ a 17%, intake, and exhaust does not strike me at all as odd. Evidently even less odd when, according to those posting above me, this particular dyno reads on the high side of things.

once again.....a single dyno pull is meaningless. in archaeology we say it 'lacks provenance'...like finding the coolest artifact lying in the parking lot of the locall mall. without a frame of reference, it's a cool thing but meaningless in the big picture.

 

It was 3 pulls if it matters Doug.....I can email it to someone if they want to post it...i cant seem to be getting it up uggghhh

Ahh there she is

 

You're running really lean... Eek. What kind of injectors are you using?

 

As of now stock....should i run it easy until i get bigger injectors? I thought it felt lean up to.....

Jack

 

I have a 15% pulley, stock ecu, ALTA CAI and the GP works I/C. I went on the dyno and it pulled out 181 BHP. The thing is that the guy that was there pushed the car only to 6795 rpm and not until 6950.

Is this a good result or should i start looking for pressure loss???

 

What kind of dyno?
What kind of correction factor was used?
...there's a dozen or more questions that could be asked that could effect the outcome of a dyno run. Your number suggests to me that you were running about 155-160 whp, which again, depending on conditions, sounds about right. You might have gotten a couple more hp running to 6900. The most important part about dyno runs are the deltas achieved between modifications. Could you have a boost leak...sure?!?!!?? But without more data, it'd be real hard to tell just looking at the numbers. Try this; get a stopwatch and time yourself from 30-70 mph on a flat road and let us know what your average time was...try about 5 runs and throw out the best and worst times, then average. Good luck and welcome to the jungle of info called NAM

 

Highlife do you have a larger pic of your sig? need it for screen saver FTW

 

If it hadn't been for that damn R56, those bikinis would've been off


***skip to 2:24 if you're feeling impatient

 

True True, nice video...

Jack

 

That's awesome!

 

Thanx a lot for your response (and for the welcome). The dyno was MAHA. By the way one friend of mine was in the dyno before me and pulled out 190 BHP with 17% pulley only.
Tonight i'll do the time tests you recommended and i'll post the results. Please have in mind that my Mini is heavy (roof, leather, clima, stock wheels with runflat tires, me - 94 kg)
