Drivetrain BOOH YA ! Awesome dyno #'s !!

bhp*.88 = whp
whp/.88 = bhp
( this is for a 12% loss)
bhp*.88 = whp
whp/.88 = bhp
( this is for a 12% loss)
Stock: 163 BHP * .88 = 143.4 WHP
Mod: 209 WHP / .88 = 237.7 BHP
Mod 209 WHP - Stock 143.4 WHP = 65.5 HP or a 46% gain. So I admit that there's a discrepancy of 0.1 HP in my calculation.
But my point is that these numbers see pretty high for a WHP measurement and may be a result of WHP to BHP confusion/conversion issues. And, if this IS in fact an accurate WHP number, WOW!

you were the guy with the "white cane" right???????

2 corrections to an earlier post.
My car is an 05 so its actually rated at 170 crank, and the # are WHP #'s and the car feels like its making power!
Can it kill a vette? Depends who is driving the vette...Personally I will say no when we are talking straight line acceleration but that isnt where the mini shines and not what it was biult for and not what I want it for. Guaranteed to spank honda's though

Just had a look at those plots. Lots of folks would like to see Dyno sheets like those.
I dunno about max power on run 8, but I really like the plot on run 7. ...That hp climbs at an almost perfectly straight line!!!
and the torque curve has fewer dips.
Did you decide to further modify fueling for safety? Looking at run 7 vs. 8 there's significantly more fuel in the mix between 5 & 5.5k rpm.
Also noticed that run 8 is a little more lean all the way from 2.5k on up to 5k rpm. But the graph doesn't show much visible gain over run 7 in that range. Did the butt dyno tell you that you were pulling stronger through the mid? Irrespective of this, you'll save some gas on the run 8 tune for daily driving. ...Unless you have your foot into it constantly.
El, what was your A/F target(s) up in the ranges above 4.5K?
Good stuff guys! & thanks for sharing detlman!

I am not really sure about the tuning part because that is El's dept.
All I can say is my car pulls very strong from about 3K all the way to the limiter! clean smooth and linear. There are a couple little spots I need to work on with the low throttle settings. Alll around good stuff !

that laid down the 202whp first run
2 tweaks later and 209whp...... with a few ponies still sitting in reserve
first car I have seen lay down over 205whp with STOCK injectors....

So would you call what I have blind faith in TBD (Tuned by the Devil)=Thinking inside the box.

I feel an urge to get a 100+whp boost on my crappy slow car, to me atleast, to really be able to kick butts:smile:
All this talk about HP is making me feel nautious.. not at the most
Nice setup you got there
Keep going up and up and up... then you'll need an engine rebuild to handle even more and more and more... you get my point.
Where are the companies that were willing to get the twinscrew setup out and running... it just died out
El D : Is it possible for you to provide us with a 0-100km/h run so we can get an idea of what to expect? A video of the car in action maybe? Am I asking too much?

The stock Mini can do 0-60 in 6.9 seconds. I really doubt 67 more hp is going to knock 2+ seconds off a run to 60. Not going to happen. He would have to be putting down 300whp to start giving the Vette a run for his money.
Im yet to see a stock car on that dyno. However, the place that is tuning my unichip is going to use a different dyno than the one Ive been using to measure mod gains.... we will see if I can throw down 200+ on both of em
Most 15%+intake+exhaust cars are throwing down low 180s.

over 100 mini's have been dyno'd on this particular dyno
I have done mine there and in Phoenix and they were within 1-2 hp of each other.... If you do the tests the same there are very little differences in dyno's.... it's operator error in my opinion

1st run 152.8 hp 142.6 ft/lbs.
2nd run 154.4 hp 140.3 ft/lbs.
3rd run 156.9 hp 141.5 ft/lbs.
My a/f ratio was 15 (ouch)
There were two other stock engines there that day. One did 153.6 hp, and the other did 161.9 hp. I believe they were both 04's. I was really bummed that I didn't do better when I saw that guy pull 161.9 hp with an older model. But his car wasn't completely stock. He had no engine mods, but he had lightweight rims. I don't know if light rims (in contrast to us running the S Lites on the dyno) would transmit into that much of a difference, but the completely stock 04 and me (both running S Lites) were relatively close, with my 05 edging slightly above. I'd like to go dyno my car with new rims to see if there's a difference, but I'll at least have my pulley on by the time I'm ready to buy new corners.
The only people who have dyno'd above 200 hp there without a twincharge (El correct me if I'm wrong) are detlman and D1JL, who have all the typical bolt-ons plus cam, head, and A'PEXi. In fact, I believe the only MCS's who have run over 200 hp there are running the A'PEXi...

How many Mini engnes are those
You better trailer a gas station behind you in that Z06 then maybe two when modded.. lol

The C-6 Z06 with 427 c.i. (7.0 liters) LS7 engine is going to be producing in the neighborhood of 500/500 from the factory. Wait until people like Lingenfelter Performance get to tweaking the LS7 engine. Think the MINI is going to be a vette killer? Maybe in a wet dream. In fact, the Viper better watch out; a LS7-engined Z06 is taking a bead on it.

1. MINI has rated the '05 MCS in stock form at 168 (US) BHP.
2. BelowRadar has a stock '05 MCS.
3. BelowRadar's best pull was 156.9 WHP on the DRS DynoJet.
Using the accepted 12% driveline loss factor, we can verify the accuracy of the DRS DynoJet WHP calculation by dividing BelowRadar's 156.9 WHP by the .88 driveline loss factor to arrive at MINI's 168 BHP rating, yes?
156.9 WHP / .88 = 178.3 BHP ????
This is obviously 10.3 BHP higher than the stock factory BHP specification. How can that be? Read into that what you may but I believe that DRS's DynoJet may be the culprit and may be consistently reading about 10.3 HP too high.
However, detlman's best pull was 209 WHP and, assuming the 10.3 HP dyno inaccuracy is fixed and not linear or exponential, the new BHP can be calculated as follows:
209 WHP / .88 = 237.5 BHP - 10.3 HP correction = 227.2 BHP
Based on the mods detlman has made, 225 - 227 BHP sounds right on target.
In and of itself, the 10.3 HP correction does not affect the good work El Diablo Rojo does; he is working with net-change analysis from run-to-run. It is when one those numbers is taken as an absolute value to the "outside" world as a "standard measurement" that a problem surfaces.
I suppose the only way to truly develop a "standard dyno rating" is to use a single, high-end dyno (like the Mustang??) to measure all MINIs; obviously not a practical answer. Thus, we have to recognize that there will be a variance between dynos from the various manufacturers.
Again, The Red Devil at DRS has done a terrific job tuning these MINIs and I am not trying to flame anyone's fine efforts or well-sorted mods here. You are all helping to push the performance envelope of our cars and you should be recognized for this.
However, as with many numbers that are thrown around these forums, there needs to be a common sense examination to determine what's behind them. There are some very smart technicians hanging out on NAM (Ryan Malcolm, Randy Webb, Andy Ross, and many others) and I think they will echo my concern for a more critical assessment of the "pronouncement of numbers".
Andy Ross' signature says it all.
