Mark from Psi Fi was at Helix to get some baseline dynos before installing his turbo kit. We started goofing off after getting woozy on carbon monoxide and decided to dyno the car while hand-spraying water onto the intercooler. The results were pretty impressive.


BTW, we had just finished dynoing a JCW car with Alta intake, MTH, and header. Mark's car out-powered that car with less than $1000 in mods. He has HAI, Helix 19%, one-ball, and tuned with the Psi Fi Powerpaq with 420cc injectors.

Here are the graphs for the dry and water sprayed runs:

 

:smile:

That's pretty cool info. Thanks.

 

What is a Psi Fi powerpaq????

 

Piggyback fuel/timing computer.

 

By how much was the other car outpowered?

Alex

 

Only by a couple of hp and ft pounds.

BTW if our dyno is looking suspiciously like a dynojet it's because I need to recalibrate the torque arm. Over time the numbers tend to creep up. You can assume that these raw numbers are inflated by maybe 5 to 8 hp, although the difference is accurate. Nonetheless, these both are very strong cars (Mark's hitting nearly 97 at the strip last week).

More info and cool Powerpaq options coming soon.

 

Since everybody is saying that you dyno is more conservative with numbers (I hope I used the right word) those are some very nice numbers.
Eric.....a stock JCW car is at about 167hp on your dyno? I just would like to see on how bog the difference is from both cars....since I believe the JCW kit being a true 200hp motor otherwise I would wonder about BMWs testing specially for TUV.

Eric: We are all waiting holding our breath Go-Go-Go for it!!!!!!!

 

We are jonesing here man... Just waiting on 1 part(should be done this week) and then it all goes on the cars(erics as well as mine). I'm going to tune in the 530cc injectors on my car today in anticipation of the turbo kit. We should have some dyno/track data as well as installed pics in the very near future.

 

Eric,


What numbers did the JCW show? Could you post your graphs for the JCW, I am really interested in seeing numbers for this modification. Also was the graph you have up of the Psi-Fi car? Thanks.

 

I've been lurking about, reading about heat and the effect of finely misted
liquids on heated surfaces. Take a look at what the Porsche privateers are up to:

Alex:

We just received our dyno computer back from Mustang for service. They changed some of the MANY calibrations on it, and the numbers were showing high yesterday. Yes, JCW cars consistently show 165-168 whp on our dyno, which is no where near 200 hp. Using a 12% drivetrain loss, it's 184.8-188.16. I don't know whether it's BMW or the Cooper garages that are claiming 200hp, but they're not close on our dyno. But so what else is new: imaginary tuner numbers are everywhere. Can you imagine me trying to sell our Stage one kit (RDR intake, 15%, exhaust) as our "192.64 hp kit"? Wouldn't sell a-one, even though they are quicker than a JCW.

The JCW car was a paying dyno customer and thus I will leave it up to him whether he wants to post his dyno plots (are your ears burning, Trevor) He is at the track this weekend, so I don't know if he's tuned in. BTW, his is no ordinary JCW car. His sweet little ride has a bunch of go-fast stuff on it: all top shelf.

One last interesting note: in this week's Autoweek, they compare a R32 to an EVO. They mentioned that the water sprayer on the EVO made no power, and was designed for those in love with automotive doo-dads. That on the same day that we saw a substantial increase on the MINI. Go figure.

 

Eric,

thanks for the reply. Dyno numbers...never know what to do with them. That is why I wanted to know about the stock JCW number on your dyno to see what the gain over it is/was on the 2 cars. So if the numbers where with the new calibrated computer I wonder what the stock JCW does now on your dyno. There are always so many factors that take a role with dyno numbers.

Thanks again Eric,

Alex

 

Psi-Fi:Mark, I need a fix bad. Help me out How about your 530cc injectors on my car with your fuel system controller. That will hold me for a few weeks.

 

This guy is running 530cc injectors and yet I don't hear Chris saying anything about too MUCH INJECTORS.... roflmao.....sigh*******

Why knock something until you tried it to see if it really doesn't work? enjoy

 

Eric,

You can post my dyno numbers and the comparison chart comparing the two cars, I don't have a problem with it.

 

I just don't understand how you can compare a car with a 19% pulley against a car like the JCW with less than a 15% pulley. How about you installing a 19% on the JCW and put the uprated injectors in it and tell us what those numbers are. You guys at Helix just love knocking the JCW. People buy them because they want them for whatever reason they have.

 

my guess is they are attacking the $$$ spent on JCW vs the $$$ spent on less costly mods to get the same or more HP..... I have nothing against either but bang for the buck is where it's at in my book.

 

Besides, the JCW package comes with those really expensive badges and a warranty.

 

That JCW is mine and Eric is really not knocking my car, its a known fact that anyone can get the same amount of power out of an S by adding their own parts for a lot less. The bottom line here is there was only a 2 HP difference between the cars before we started the water spray, and the mods on the other car only cost $1K in parts.

We guys who spent our money on the JCW should not be so thin skinned about the price comparison for the amount of power, look at it this way we could afford it so we got it.

I understand what you are saying. But show me the numbers that would come from your car if it had a 19% pulley. I would have to think there would be more than a 2hp difference on your side with a 19% pulley installed ,not to say even more with injectors..But then again why would someone want bigger injectors on car that runs pig rich as it is. I could see bigger injectors with a big valve head,cam and headers. Then again I could be all wrong. I also don't believe all you got for your money is a warranty and so called expensive badges.

 

To some people JCW is more than a warranty and badges. I do not have JCW and I will not have it. I just felt that I needed to chime in and let people know that first of all, this is not a JCW bashing thread. Second, this forum is not for bashing anyone elses MINI. We all love our cars, that's why we're here. If you can't say something nice about someone elses car, ESPECIALLY A MINI, you should keep it off this forum. Thank you I feel better now.

 

I am always suprised at the low numbers that some people get with the JCW. I am really interested in the JCW and am going to purchase it with my '05. Of all the dyno parties that I have seen, the JCW has consistently been the top or near the top for most mod groupings. Obviously there are some who have spent over $10,000 in performance mods and are obviously getting higher numbers. Granted if you were just in for bang for the buck you can get more power for less money. But I think some of the criticism is unwarranted at times. I hear some people say my 15% pulley and Alta intake can beat a JCW. I just can't get that. Especially since the JCW is basically a 15% pulley anyway (13.8% exactly). At this point I am ignoring the criticism. I am really excited at getting the JCW. First for the heritage and pedigree. The resale value on a bunch of 3rd party kits doesn't come close to the retained value of the JCW. Second, the proven dependability and warranty. And third, I know the company will be around to continue to support the product. Not knocking any vendors but nothing stops Helix from closing up shop tomorrow, or MTH to stop supporting their chip. We have seen it with the Powerchip already and the problems that come about. That is most likely not anything we will experience with JCW.


Now that I am off my soap box, I am interested in seeing the dyno plots.

 

Trev:

Will post tomorrow if I get time between 2 installs. I heard you had a good weekend at the track, save for some ECU issues.

BS: You're right, a JCW with a 19% pulley would be sweet. We have done 4 JCWs with 17%, and they run very well. The JCW has collector value and presige that a Helix Stage 1 would never have. The Helix Stage 1 has a price and performance that JCW can't touch. I'm not hatin', I'm just statin' (I apologise: I hade about 4 Johnny Cochran slogans bouncing around in my mind, and that was the least tasteless).
