Please continue your development work, this shows promise!

 

so that means they did some changes from the last time.. which is a good thing.. cant wait to see the final product...Way motor works... do u guys have anything or a date when you would be testing?

 

MaitlandImports what kind of mods are you running to get that power other than a sprintex blower and modded IC?

My car is a DD and will occasionally see some track use, but primarily I want more power for the fun of it. 3k could buy me a lot of power mods.

 

I don't know what Way's involvement is on this, As far as I know mine is the only working model on a running vehicle. We were developing this with Revolution Mini and Jan has stepped away from the project with concerns about the product. Since Jan stepped away from the project the Us Distributor has mentioned about every Mini shop in the country to me as distributors of the product so you'll see it forsale from everyone. I'm told I'll get the first updated version soon. I look forward to that and will post info when I get it.
Other mods to the car are an RMW head, Cam, Header. It made the same hp with a big intercooler as with the stock one.
The Blower they show in the PDF I was told will be running the stock pulley tensioner system and will be set up for much lower boost then I run. They have specifically sold me they are not interested in selling this as a "race" kit making 15-20 psi like I have mine doing. The Stock tensioner does not apply enough tension and that was one of the first things to go. We could watch the arm on the tensioner bend and flex as you would rev the engine and you could smell the belt slipping on the dyno (and see it in the dyno curve). They sent me a different tensioner which took some work to make work, it made more power but makes an absolute racket and it flex's and smacks the timing cover at idle. A LOT more work needs to be spent on the belt tensioning if you want big hp numbers. But from what I've been told I think the plan is to keep them relatively low boost and run the stock tensioner.

 

After seeing it make good power first pull and then watching the thing make less and less power every pull, even after adding Meth was beyond frustrating, have to say something was terribly wrong with it.... Think the last pull was like 240 with every fan we could find with in a mile blowing on it..

Confidence was definitely low the next morning at the UTCC; then the freaking so called weld breaking first lap on the IC horn was ....

PS: Gotta say it took guts to walk away from it after all the personal time and money you guys had invested in it... But guess sometimes ya just have to call a spade a spade and move on...

 

Ian thanks for your thoughts. I totally agree that there is more development that needs to go into it before it will ever be ready for sale. That's what happened when we were working on the M62 supercharger kits, the cost for the gain never made it worth it. It did work, we actually have 2 cars still running, but the big numbers over were never there, the same amount of money on an M45 would net more power.

 

Hmmm sounds like there are a good number of concerns that need to be addressed...

 

I do believe that's the exact same issue Jan ran into on the TVS, by the time you got done changing everything that needed to be changed to make the power your had an insane amount of money in making it work. We added up out labor time here on this blower and in pure time alone if you were a customer paying we have near $10,000 in labor involved in just making it work. I haven't even thought about sitting down to add up the misc parts I've had to buy to try to solve an issue, only to strap it on the dyno and do the same thing. The Good news is it does go a hell of a lot faster then any M45 will ever go. The Bad is it just needs more work and I think some of the work needs to go on inside the blower it's self. I mean our initial test day the car rode the bumper of a 380whp Z06 till the top of 5th gear at sebring. It's quick, it just doesn't stay quick right now. I do believe we have the belt slip issue solved as it doesn't scare the belt very much any more but it took a couple different idlers and a different tensioner. The problem is the thing still hits a wall and every dyno pull the wall gets lower and lower.

 

Borrowed this from another board. The company that did the test is not on this forum...
==================
We have finished the testing on the Stage II kit and here are the results... the mods on the Green test mini is as follows:

2006 MCS Manual, stock ECU, stock 1.6L (stock pistons and rods, stock compression), stock clutch, stock tranny, stock intake, stock coils-pack and wires.

Modifications:
- Sprintex S5-210 unit.
- TPR1 Ported head with matched Intake Manifold.
- Mynes V2 header with factory CAT.
- MegaMINI Cam shaft.
- GP Intercooler.
- Bosch 550cc OE Injectors.
- Nvidia exhaust.
- Bytetronik FA53 Tuning Kit.
- NGK BKR8EIX Spark plugs.

Baseline:
On the M45 stock supercharge with the 15% reduction pulley, it put down 219whp / 177wtqe.

Sprintex Stage II kit:
On the 91 octane pump gas, car put down 243whp / 197wtqe.

Remarks: Being in California, the '91 octane' we get at the pump doesn't really provide the actual potential of this super charger. For guys in areas where you have access to higher octane fuel, you should hit 250whp without any issue.

On E85 fuel, we were able to get the power level up considerably: 266whp / 220wtqe.


Power Progression from M45 (area in blue) to Sprintex (area in yellow):



Here is how the dyno graphs look on the S5-210 kit (91 Octane vs E85 fuel):


Here is a comparison from the M45 baseline to the S5-210 with E85 (max potential of the Stage II kit as tested):


Here is the comparison between the M45 and Sprintex (both on E85 fuel):
Note: the M45 on E85 was done prior to addition of the Thumper head. We didn't have time to test on E85 with the M45 after the THumper head install. So the Sprintex HP and Torque is aided by the addition of the Thumper Stg I head and Ported Intake Manifold..
=> M45 : 228WHP / 187Wtqe
=> Sprintex 60mm: 266WHP / 220Wtqe (aided by TPR1 + Ported IM)


Triple Overlay:
Top one: Sprintex on E85
Middle graph: Sprintex on 91 Octane
Bottom graph: M45 on 91 Octane.



Data Logs shown below:

4th Gear dyno with the 16 PSI Pulley:


4th Gear dyno with the 19 PSI Pulley:



About two weeks ago (March 2011), we had a heat spell here in Southern California and the outside temperature was 95-F; so while cruising on the Freeway, did the following two logs (5th Gear and 6th Gear)...




Note: Even when the outside temp was 95F, the IAT was under 51C cruising at 80 MPH. No over-heating whatsoever

Test Recap:
On almost 270whp and 220wtqe, it's shocking for me to say this, but the car is a little scary to drive in its current form without upgraded clutch, better tires/suspension and definitely needs a good LSD. So before we move onto Stage III testing, the before-mentioned parts will have to be upgraded before we make any more HP.

In 1st and 2nd gear, if you give it more than 30% throttle, the front tires will just spin continuously. By the time you get to the top of 2nd and going into 3rd, that's when the wheel spin stops. The power is awesome and the 220 torque is definitely noticeable. Even while passing in 6th gear on the freeway, instead of having the need to down shift to 5th, one can simply give it a little more gas and the car will scoot and go...

We know from testing the S5-210 on the Jeep that this Sprintex unit is definitely capable of producing 300whp (b/c we actually got 300whp from a Jeep ... so the factors that are limiting the full potential of this SC are other parts.

So for Stage III testing (which will be "on-going basis"), we will try the following mods (utilizing the Stock ECU):
- TPR2 or TPR3 Head (Thumper, we need to talk when you get back from vacation :bounce: )
- W/M system
- bigger fuel injectors
- upgraded Suspension and brakes
- OS Clutch and OS LSD

Thus far, we have run into no over-heating issues. Even on back to back to back dyno runs, the car produces very consistent HP and wtqe (if the power go down by 3HP, the Torque comes up a couple; and if HP goes up a couple, the Torque goes down by a couple). The Max HP produced in Stage II test config was 270HP, max torque was 220.

Will post more data and data-logs from the streets and freeway driving. The past few days got up to the 98F temperature and we have those logs to share as well. Overall, very nice setup and i'm keeping this Sprintex on the Green MINI permanently

 

That's a lot of MODS and money for 243 HP.. Lots of MINIs out there with stock SC and just the basics plus, head, cam, header, and tune with that or a few more..
Granted that is with a mildly ported head but if your spending that kind of money go all out and get the better head..

 

^ Those are real hp numbers not jacked up numbers you see around here....

 

+1 To what D-MAN said.

I am planing on installing one of theese on my car in a month or two. So we will see once I get the last little bit of the cash.

 

I have been to a couple of tuning days in the last couple of years. A very wide range of stock and modded cars there... Seen the numbers for myself. Nothing jacked up about them..
Yes the Sprintex will get you some HP but if you "only" want 250 HP there are other cheaper ways to get there is all I'm saying.. Then add the Sprintex or other SC and see what you have then!!!

 

Watching this closely, but I don't want to be the guinea pig on this one. One pull on a dyno is great, but what'll it look like on pull number 20?

There were ALOT of issues with the Sprintex, which Maitland, to his credit, alluded to. There have been changes to the unit since this happened, which hopefully will help. But the development of the Sprintex, without getting into the gnarly specifics, has been anything but smooth.

I'll wait to see how things work out with the Rotrex, which I believe is available now too (not 100% sure on that one), and when my SC finally bites the dust, hopefully there'll be enough long term data out there to make an educated choice.

 

Where can I find the test data from Mailand or Rotrex? I tried the search button n found nothing. Tks

 

MINIProwler, the supercharger thing is kind of a can of worms at the moment.

I'd encourage you to talk to both Myne's, who have the Sprintex, and RMW, who has the Rotrex. I am slightly biased here, and I don't want to start a pissing contest on these boards.

IMHO, I'd wait a year on either these. In fact, that's the very earliest I'd consider either one of these, but more power to anyone willing to take the plunge (Just please, please, do some data logging after it's installed, and hang on to your old SC).

We're running out of things to do that are relatively affordable on the R53; the SC thing is the FOM at the moment. I've seen too many FOM's come and go to hop on this bandwagon until there is more long term data out there.

 

The Sprintex S/C's are nothing new to other cars (i.e. V8's, etc) and many of those guys have had quite a few problems, especially with vehicles that are tracked on a road course. The common item I remember is extremely high temps on the track & bearing issues, that brought your net power gain to 0 (or even a loss) compared to some more common blowers.

If it works I'll be interested, but I'm going to wait & see if the road racers (i.e. people that spend more than 15 seconds at full throttle) still like it after a year of abuse & data logging.

 

I think this new kit is being marketed as a "Street kit". How many people actually spend that much time at full throttle on the street?

 

I don't know but does that mean you're not allowed to take the car to the track at all? Marketed as street or not, it has to be able to take some extreme tolerances and be able to perform.

 

The unit being tested now is of a newer generation . Issues mentioned above were for a previous unit. Time will tell how well they have rectified any problems there may have been .

Randy

 

That is one nice piece of hardware!

 

Randy though you are right on it being a new design of blower and all the isues that Jan and the others had have been resolved. (ie: NEW tensioner design, NEW inlet and outlet that is all cast, and a couple others) The production units are avalible for sale NOW. All the testing is done, SPRINTEX is a big company in Austrailia that does OE castings and S/C systems for the Korean and Chineese market, so when they want something done they dont waste time.
Hell if I had another $1200.00 I could be bolting one of theese on next week!

 

You need to get that $1200 nao! Wanna see how well it does in our altitude. Time to sell some blood and sperm bro.

 

Which begs the point...Why would a strictly street driven car need a new, more powerful SC? How much is it going to add for a quick drive to the supermarket (Damn, I just beat that Nissan Cube in the Piggly Wiggly parking lot for the closest non-handicapped spot to the entrance--couldn't have done it without the new SC!!), or an occasional spirited drive?

That's why a few of us would like to see some data for the track, what it's doing after 10 or 20 laps--IMHO that's the best application for something like this.

****'sgarage said the testing has been done; be nice to see some of that data. If the Sprintex isn't for the track, that's cool, I'll move on, although I don't really see the point of it. If it is, and Sprintex tested it, let's see what it's doing after 10 and 20 laps--if it's holding up, then that's awesome, and it's in the running along with the Rotrex (which hopefully will have the same type of data available at some point) for eventually (when there is some long term data on both) replacing my SC.

 

$1200

Last I looked this kit was just short of 4k not including installation and a tune to make all work for the street.
